有什么区别，主要是两方面：一是交流群实时性高一些，二是交流群会更活跃一些。 8 | 9 | 另外，Issue 主要是用来发布一些项目中的错误和一些改进建议，当然也可以发布一些可以讨论的问题。 10 | 11 | 交流群可以讨论的内容比较广，例如在阅读本项目过程中不理解的地方可以在交流群中寻求别人的帮助、新技术的讨论、招聘信息、学习和工作的感受等等。 12 | 13 | 交流群不讨论政治，不讨论有争议性的话题，不发表仇视言论，不传播谣言，不发布广告（招聘信息之类的可以）。 14 | 15 |

23 | 24 | ## 发布/订阅 25 | 26 | 消息生产者向频道发送一个消息之后，多个消费者可以从该频道订阅到这条消息并消费。 27 | 28 |

29 | 30 | 发布与订阅模式和观察者模式有以下不同： 31 | 32 | - 观察者模式中，观察者和主题都知道对方的存在；而在发布与订阅模式中，发布者与订阅者不知道对方的存在，它们之间通过频道进行通信。 33 | - 观察者模式是同步的，当事件触发时，主题会调用观察者的方法，然后等待方法返回；而发布与订阅模式是异步的，发布者向频道发送一个消息之后，就不需要关心订阅者何时去订阅这个消息，可以立即返回。 34 | 35 |

36 | 37 | # 二、使用场景 38 | 39 | ## 异步处理 40 | 41 | 发送者将消息发送给消息队列之后，不需要同步等待消息接收者处理完毕，而是立即返回进行其它操作。消息接收者从消息队列中订阅消息之后异步处理。 42 | 43 | 例如在注册流程中通常需要发送验证邮件来确保注册用户的身份合法，可以使用消息队列使发送验证邮件的操作异步处理，用户在填写完注册信息之后就可以完成注册，而将发送验证邮件这一消息发送到消息队列中。 44 | 45 | 只有在业务流程允许异步处理的情况下才能这么做，例如上面的注册流程中，如果要求用户对验证邮件进行点击之后才能完成注册的话，就不能再使用消息队列。 46 | 47 | ## 流量削锋 48 | 49 | 在高并发的场景下，如果短时间有大量的请求到达会压垮服务器。 50 | 51 | 可以将请求发送到消息队列中，服务器按照其处理能力从消息队列中订阅消息进行处理。 52 | 53 | ## 应用解耦 54 | 55 | 如果模块之间不直接进行调用，模块之间耦合度就会很低，那么修改一个模块或者新增一个模块对其它模块的影响会很小，从而实现可扩展性。 56 | 57 | 通过使用消息队列，一个模块只需要向消息队列中发送消息，其它模块可以选择性地从消息队列中订阅消息从而完成调用。 58 | 59 | # 三、可靠性 60 | 61 | ## 发送端的可靠性 62 | 63 | 发送端完成操作后一定能将消息成功发送到消息队列中。 64 | 65 | 实现方法： 66 | 67 | - 在本地数据库建一张消息表，将消息数据与业务数据保存在同一数据库实例里，这样就可以利用本地数据库的事务机制。事务提交成功后，将消息表中的消息转移到消息队列中，若转移消息成功则删除消息表中的数据，否则继续重传。 68 | 69 | ## 接收端的可靠性 70 | 71 | 接收端能够从消息队列成功消费一次消息。 72 | 73 | 实现方法： 74 | 75 | - 保证接收端处理消息的业务逻辑具有幂等性：只要具有幂等性，那么消费多少次消息，最后处理的结果都是一样的。 76 | - 保证消息具有唯一编号，并使用一张日志表来记录已经消费的消息编号。 77 | 78 | # 参考资料 79 | 80 | - [Observer vs Pub-Sub](http://developers-club.com/posts/270339/) 81 | - [消息队列中点对点与发布订阅区别](https://blog.csdn.net/lizhitao/article/details/47723105) 82 | -------------------------------------------------------------------------------- /notes/系统设计基础.md: -------------------------------------------------------------------------------- 1 | 2 | * [一、性能](#一性能) 3 | * [二、伸缩性](#二伸缩性) 4 | * [三、扩展性](#三扩展性) 5 | * [四、可用性](#四可用性) 6 | * [五、安全性](#五安全性) 7 | 8 | 9 | 10 | # 一、性能 11 | 12 | ## 性能指标 13 | 14 | ### 1. 响应时间 15 | 16 | 指从某个请求从发出到接收到响应消耗的时间。 17 | 18 | 在对响应时间进行测试时，通常采用重复请求方式，然后计算平均响应时间。 19 | 20 | ### 2. 吞吐量 21 | 22 | 指系统在单位时间内可以处理的请求数量，通常使用每秒的请求数来衡量。 23 | 24 | ### 3. 并发用户数 25 | 26 | 指系统能同时处理的并发用户请求数量。 27 | 28 | 在没有并发存在的系统中，请求被顺序执行，此时响应时间为吞吐量的倒数。例如系统支持的吞吐量为 100 req/s，那么平均响应时间应该为 0.01s。 29 | 30 | 目前的大型系统都支持多线程来处理并发请求，多线程能够提高吞吐量以及缩短响应时间，主要有两个原因： 31 | 32 | - 多 CPU 33 | - IO 等待时间 34 | 35 | 使用 IO 多路复用等方式，系统在等待一个 IO 操作完成的这段时间内不需要被阻塞，可以去处理其它请求。通过将这个等待时间利用起来，使得 CPU 利用率大大提高。 36 | 37 | 并发用户数不是越高越好，因为如果并发用户数太高，系统来不及处理这么多的请求，会使得过多的请求需要等待，那么响应时间就会大大提高。 38 | 39 | ## 性能优化 40 | 41 | ### 1. 集群 42 | 43 | 将多台服务器组成集群，使用负载均衡将请求转发到集群中，避免单一服务器的负载压力过大导致性能降低。 44 | 45 | ### 2. 缓存 46 | 47 | 缓存能够提高性能的原因如下： 48 | 49 | - 缓存数据通常位于内存等介质中，这种介质对于读操作特别快； 50 | - 缓存数据可以位于靠近用户的地理位置上； 51 | - 可以将计算结果进行缓存，从而避免重复计算。 52 | 53 | ### 3. 异步 54 | 55 | 某些流程可以将操作转换为消息，将消息发送到消息队列之后立即返回，之后这个操作会被异步处理。 56 | 57 | # 二、伸缩性 58 | 59 | 指不断向集群中添加服务器来缓解不断上升的用户并发访问压力和不断增长的数据存储需求。 60 | 61 | ## 伸缩性与性能 62 | 63 | 如果系统存在性能问题，那么单个用户的请求总是很慢的； 64 | 65 | 如果系统存在伸缩性问题，那么单个用户的请求可能会很快，但是在并发数很高的情况下系统会很慢。 66 | 67 | ## 实现伸缩性 68 | 69 | 应用服务器只要不具有状态，那么就可以很容易地通过负载均衡器向集群中添加新的服务器。 70 | 71 | 关系型数据库的伸缩性通过 Sharding 来实现，将数据按一定的规则分布到不同的节点上，从而解决单台存储服务器的存储空间限制。 72 | 73 | 对于非关系型数据库，它们天生就是为海量数据而诞生，对伸缩性的支持特别好。 74 | 75 | # 三、扩展性 76 | 77 | 指的是添加新功能时对现有系统的其它应用无影响，这就要求不同应用具备低耦合的特点。 78 | 79 | 实现可扩展主要有两种方式： 80 | 81 | - 使用消息队列进行解耦，应用之间通过消息传递进行通信； 82 | - 使用分布式服务将业务和可复用的服务分离开来，业务使用分布式服务框架调用可复用的服务。新增的产品可以通过调用可复用的服务来实现业务逻辑，对其它产品没有影响。 83 | 84 | # 四、可用性 85 | 86 | ## 冗余 87 | 88 | 保证高可用的主要手段是使用冗余，当某个服务器故障时就请求其它服务器。 89 | 90 | 应用服务器的冗余比较容易实现，只要保证应用服务器不具有状态，那么某个应用服务器故障时，负载均衡器将该应用服务器原先的用户请求转发到另一个应用服务器上，不会对用户有任何影响。 91 | 92 | 存储服务器的冗余需要使用主从复制来实现，当主服务器故障时，需要提升从服务器为主服务器，这个过程称为切换。 93 | 94 | ## 监控 95 | 96 | 对 CPU、内存、磁盘、网络等系统负载信息进行监控，当某个数据达到一定阈值时通知运维人员，从而在系统发生故障之前及时发现问题。 97 | 98 | ## 服务降级 99 | 100 | 服务降级是系统为了应对大量的请求，主动关闭部分功能，从而保证核心功能可用。 101 | 102 | # 五、安全性 103 | 104 | 要求系统的应对各种攻击手段时能够有可靠的应对措施。 105 | -------------------------------------------------------------------------------- /notes/Docker.md: -------------------------------------------------------------------------------- 1 | 2 | * [一、解决的问题](#一解决的问题) 3 | * [二、与虚拟机的比较](#二与虚拟机的比较) 4 | * [三、优势](#三优势) 5 | * [四、使用场景](#四使用场景) 6 | * [五、镜像与容器](#五镜像与容器) 7 | 8 | 9 | 10 |

11 | 12 | # 一、解决的问题 13 | 14 | 由于不同的机器有不同的操作系统，以及不同的库和组件，在将一个应用部署到多台机器上需要进行大量的环境配置操作。 15 | 16 | Docker 主要解决环境配置问题，它是一种虚拟化技术，对进程进行隔离，被隔离的进程独立于宿主操作系统和其它隔离的进程。使用 Docker 可以不修改应用程序代码，不需要开发人员学习特定环境下的技术，就能够将现有的应用程序部署在其他机器中。 17 | 18 | 参考资料： 19 | 20 | - [DOCKER 101: INTRODUCTION TO DOCKER WEBINAR RECAP](https://blog.docker.com/2017/08/docker-101-introduction-docker-webinar-recap/) 21 | - [Docker 入门教程](http://www.ruanyifeng.com/blog/2018/02/docker-tutorial.html) 22 | 23 | # 二、与虚拟机的比较 24 | 25 | 虚拟机也是一种虚拟化技术，它与 Docker 最大的区别在于它是通过模拟硬件，并在硬件上安装操作系统来实现。 26 | 27 |

30 | 31 | ## 启动速度 32 | 33 | 启动虚拟机需要启动虚拟机的操作系统，再启动应用，这个过程非常慢； 34 | 35 | 而启动 Docker 相当于启动宿主操作系统上的一个进程。 36 | 37 | ## 占用资源 38 | 39 | 虚拟机是一个完整的操作系统，需要占用大量的磁盘、内存和 CPU，一台机器只能开启几十个的虚拟机。 40 | 41 | 而 Docker 只是一个进程，只需要将应用以及相关的组件打包，在运行时占用很少的资源，一台机器可以开启成千上万个 Docker。 42 | 43 | 参考资料： 44 | 45 | - [Docker container vs Virtual machine](http://www.bogotobogo.com/DevOps/Docker/Docker_Container_vs_Virtual_Machine.php) 46 | 47 | # 三、优势 48 | 49 | 除了启动速度快以及占用资源少之外，Docker 具有以下优势： 50 | 51 | ## 更容易迁移 52 | 53 | Docker 可以提供一致性的运行环境，可以在不同的机器上进行迁移，而不用担心环境变化导致无法运行。 54 | 55 | ## 更容易维护 56 | 57 | Docker 使用分层技术和镜像，使得应用可以更容易复用重复部分。复用程度越高，维护工作也越容易。 58 | 59 | ## 更容易扩展 60 | 61 | 可以使用基础镜像进一步扩展得到新的镜像，并且官方和开源社区提供了大量的镜像，通过扩展这些镜像可以非常容易得到我们想要的镜像。 62 | 63 | 参考资料： 64 | 65 | - [为什么要使用 Docker？](https://yeasy.gitbooks.io/docker_practice/introduction/why.html) 66 | 67 | # 四、使用场景 68 | 69 | ## 持续集成 70 | 71 | 持续集成指的是频繁地将代码集成到主干上，这样能够更快地发现错误。 72 | 73 | Docker 具有轻量级以及隔离性的特点，在将代码集成到一个 Docker 中不会对其它 Docker 产生影响。 74 | 75 | ## 提供可伸缩的云服务 76 | 77 | 根据应用的负载情况，可以很容易地增加或者减少 Docker。 78 | 79 | ## 搭建微服务架构 80 | 81 | Docker 轻量级的特点使得它很适合用于部署、维护、组合微服务。 82 | 83 | 参考资料： 84 | 85 | - [What is Docker](https://www.docker.com/what-docker) 86 | - [持续集成是什么？](http://www.ruanyifeng.com/blog/2015/09/continuous-integration.html) 87 | 88 | # 五、镜像与容器 89 | 90 | 镜像是一种静态的结构，可以看成面向对象里面的类，而容器是镜像的一个实例。 91 | 92 | 镜像包含着容器运行时所需要的代码以及其它组件，它是一种分层结构，每一层都是只读的（read-only layers）。构建镜像时，会一层一层构建，前一层是后一层的基础。镜像的这种分层存储结构很适合镜像的复用以及定制。 93 | 94 | 构建容器时，通过在镜像的基础上添加一个可写层（writable layer），用来保存着容器运行过程中的修改。 95 | 96 |

41 | 42 | Gradle 和 Maven 的区别是，它使用 Groovy 这种特定领域语言（DSL）来管理构建脚本，而不再使用 XML 这种标记性语言。因为项目如果庞大的话，XML 很容易就变得臃肿。 43 | 44 | 例如要在项目中引入 Junit，Maven 的代码如下： 45 | 46 | ```xml 47 | 48 | 50 | 4.0.0 51 | 52 | jizg.study.maven.hello 53 | hello-first 54 | 0.0.1-SNAPSHOT 55 | 56 | 57 | 58 | junit 59 | junit 60 | 4.10 61 | test 62 | 63 | 64 | 65 | ``` 66 | 67 | 而 Gradle 只需要几行代码： 68 | 69 | ```java 70 | dependencies { 71 | testCompile "junit:junit:4.10" 72 | } 73 | ``` 74 | 75 | 参考资料： 76 | 77 | - [Java Build Tools Comparisons: Ant vs Maven vs Gradle](https://programmingmitra.blogspot.com/2016/05/java-build-tools-comparisons-ant-vs.html) 78 | - [maven 2 gradle](http://sagioto.github.io/maven2gradle/) 79 | - [新一代构建工具 gradle](https://www.imooc.com/learn/833) 80 | 81 | # 三、Maven 82 | 83 | ## 概述 84 | 85 | 提供了项目对象模型（POM）文件来管理项目的构建。 86 | 87 | ## 仓库 88 | 89 | 仓库的搜索顺序为：本地仓库、中央仓库、远程仓库。 90 | 91 | - 本地仓库用来存储项目的依赖库； 92 | - 中央仓库是下载依赖库的默认位置； 93 | - 远程仓库，因为并非所有的库存储在中央仓库，或者中央仓库访问速度很慢，远程仓库是中央仓库的补充。 94 | 95 | ## POM 96 | 97 | POM 代表项目对象模型，它是一个 XML 文件，保存在项目根目录的 pom.xml 文件中。 98 | 99 | ```xml 100 | 101 | junit 102 | junit 103 | 4.12 104 | test 105 | 106 | ``` 107 | 108 | [groupId, artifactId, version, packaging, classfier] 称为一个项目的坐标，其中 groupId、artifactId、version 必须定义，packaging 可选（默认为 Jar），classfier 不能直接定义的，需要结合插件使用。 109 | 110 | - groupId：项目组 Id，必须全球唯一； 111 | - artifactId：项目 Id，即项目名； 112 | - version：项目版本； 113 | - packaging：项目打包方式。 114 | 115 | ## 依赖原则 116 | 117 | ### 依赖路径最短优先原则 118 | 119 | ```html 120 | A -> B -> C -> X(1.0) 121 | A -> D -> X(2.0) 122 | ``` 123 | 由于 X(2.0) 路径最短，所以使用 X(2.0)。 124 | 125 | ### 声明顺序优先原则 126 | 127 | ```html 128 | A -> B -> X(1.0) 129 | A -> C -> X(2.0) 130 | ``` 131 | 132 | 在 POM 中最先声明的优先，上面的两个依赖如果先声明 B，那么最后使用 X(1.0)。 133 | 134 | ### 覆写优先原则 135 | 136 | 子 POM 内声明的依赖优先于父 POM 中声明的依赖。 137 | 138 | ## 解决依赖冲突 139 | 140 | 找到 Maven 加载的 Jar 包版本，使用 `mvn dependency:tree` 查看依赖树，根据依赖原则来调整依赖在 POM 文件的声明顺序。 141 | 142 | 参考资料： 143 | 144 | - [POM Reference](http://maven.apache.org/pom.html#Dependency_Version_Requirement_Specification) 145 | 146 | 147 | 148 | -------------------------------------------------------------------------------- /notes/Git.md: -------------------------------------------------------------------------------- 1 | 2 | * [学习资料](#学习资料) 3 | * [集中式与分布式](#集中式与分布式) 4 | * [Git 的中心服务器](#git-的中心服务器) 5 | * [Git 工作流](#git-工作流) 6 | * [分支实现](#分支实现) 7 | * [冲突](#冲突) 8 | * [Fast forward](#fast-forward) 9 | * [分支管理策略](#分支管理策略) 10 | * [储藏（Stashing）](#储藏stashing) 11 | * [SSH 传输设置](#ssh-传输设置) 12 | * [.gitignore 文件](#gitignore-文件) 13 | * [Git 命令一览](#git-命令一览) 14 | 15 | 16 | 17 | # 学习资料 18 | 19 | - [Git - 简明指南](http://rogerdudler.github.io/git-guide/index.zh.html) 20 | - [图解 Git](http://marklodato.github.io/visual-git-guide/index-zh-cn.html) 21 | - [廖雪峰 : Git 教程](https://www.liaoxuefeng.com/wiki/0013739516305929606dd18361248578c67b8067c8c017b000) 22 | - [Learn Git Branching](https://learngitbranching.js.org/) 23 | 24 | # 集中式与分布式 25 | 26 | Git 属于分布式版本控制系统，而 SVN 属于集中式。 27 | 28 | 集中式版本控制只有中心服务器拥有一份代码，而分布式版本控制每个人的电脑上就有一份完整的代码。 29 | 30 | 集中式版本控制有安全性问题，当中心服务器挂了所有人都没办法工作了。 31 | 32 | 集中式版本控制需要连网才能工作，如果网速过慢，那么提交一个文件的会慢的无法让人忍受。而分布式版本控制不需要连网就能工作。 33 | 34 | 分布式版本控制新建分支、合并分支操作速度非常快，而集中式版本控制新建一个分支相当于复制一份完整代码。 35 | 36 | # Git 的中心服务器 37 | 38 | Git 的中心服务器用来交换每个用户的修改。没有中心服务器也能工作，但是中心服务器能够 24 小时保持开机状态，这样就能更方便的交换修改。Github 就是一种 Git 中心服务器。 39 | 40 | # Git 工作流 41 | 42 |

43 | 44 | 新建一个仓库之后，当前目录就成为了工作区，工作区下有一个隐藏目录 .git，它属于 Git 的版本库。 45 | 46 | Git 版本库有一个称为 stage 的暂存区，还有自动创建的 master 分支以及指向分支的 HEAD 指针。 47 | 48 |

49 | 50 | - git add files 把文件的修改添加到暂存区 51 | - git commit 把暂存区的修改提交到当前分支，提交之后暂存区就被清空了 52 | - git reset -- files 使用当前分支上的修改覆盖暂缓区，用来撤销最后一次 git add files 53 | - git checkout -- files 使用暂存区的修改覆盖工作目录，用来撤销本地修改 54 | 55 |

56 | 57 | 可以跳过暂存区域直接从分支中取出修改或者直接提交修改到分支中 58 | 59 | - git commit -a 直接把所有文件的修改添加到暂缓区然后执行提交 60 | - git checkout HEAD -- files 取出最后一次修改，可以用来进行回滚操作 61 | 62 | # 分支实现 63 | 64 | Git 把每次提交都连成一条时间线。分支使用指针来实现，例如 master 分支指针指向时间线的最后一个节点，也就是最后一次提交。HEAD 指针指向的是当前分支。 65 | 66 |

67 | 68 | 新建分支是新建一个指针指向时间线的最后一个节点，并让 HEAD 指针指向新分支表示新分支成为当前分支。 69 | 70 |

71 | 72 | 每次提交只会让当前分支向前移动，而其它分支不会移动。 73 | 74 |

75 | 76 | 合并分支也只需要改变指针即可。 77 | 78 |

79 | 80 | # 冲突 81 | 82 | 当两个分支都对同一个文件的同一行进行了修改，在分支合并时就会产生冲突。 83 | 84 |

85 | 86 | Git 会使用 <<<<<<< ，======= ，>>>>>>> 标记出不同分支的内容，只需要把不同分支中冲突部分修改成一样就能解决冲突。 87 | 88 | ``` 89 | <<<<<<< HEAD 90 | Creating a new branch is quick & simple. 91 | ======= 92 | Creating a new branch is quick AND simple. 93 | >>>>>>> feature1 94 | ``` 95 | 96 | # Fast forward 97 | 98 | "快进式合并"（fast-farward merge），会直接将 master 分支指向合并的分支，这种模式下进行分支合并会丢失分支信息，也就不能在分支历史上看出分支信息。 99 | 100 | 可以在合并时加上 --no-ff 参数来禁用 Fast forward 模式，并且加上 -m 参数让合并时产生一个新的 commit。 101 | 102 | ``` 103 | $ git merge --no-ff -m "merge with no-ff" dev 104 | ``` 105 | 106 |

107 | 108 | # 分支管理策略 109 | 110 | master 分支应该是非常稳定的，只用来发布新版本； 111 | 112 | 日常开发在开发分支 dev 上进行。 113 | 114 |

115 | 116 | # 储藏（Stashing） 117 | 118 | 在一个分支上操作之后，如果还没有将修改提交到分支上，此时进行切换分支，那么另一个分支上也能看到新的修改。这是因为所有分支都共用一个工作区的缘故。 119 | 120 | 可以使用 git stash 将当前分支的修改储藏起来，此时当前工作区的所有修改都会被存到栈上，也就是说当前工作区是干净的，没有任何未提交的修改。此时就可以安全的切换到其它分支上了。 121 | 122 | ``` 123 | $ git stash 124 | Saved working directory and index state \ "WIP on master: 049d078 added the index file" 125 | HEAD is now at 049d078 added the index file (To restore them type "git stash apply") 126 | ``` 127 | 128 | 该功能可以用于 bug 分支的实现。如果当前正在 dev 分支上进行开发，但是此时 master 上有个 bug 需要修复，但是 dev 分支上的开发还未完成，不想立即提交。在新建 bug 分支并切换到 bug 分支之前就需要使用 git stash 将 dev 分支的未提交修改储藏起来。 129 | 130 | # SSH 传输设置 131 | 132 | Git 仓库和 Github 中心仓库之间的传输是通过 SSH 加密。 133 | 134 | 如果工作区下没有 .ssh 目录，或者该目录下没有 id_rsa 和 id_rsa.pub 这两个文件，可以通过以下命令来创建 SSH Key： 135 | 136 | ``` 137 | $ ssh-keygen -t rsa -C "youremail@example.com" 138 | ``` 139 | 140 | 然后把公钥 id_rsa.pub 的内容复制到 Github "Account settings" 的 SSH Keys 中。 141 | 142 | # .gitignore 文件 143 | 144 | 忽略以下文件： 145 | 146 | - 操作系统自动生成的文件，比如缩略图； 147 | - 编译生成的中间文件，比如 Java 编译产生的 .class 文件； 148 | - 自己的敏感信息，比如存放口令的配置文件。 149 | 150 | 不需要全部自己编写，可以到 [https://github.com/github/gitignore](https://github.com/github/gitignore) 中进行查询。 151 | 152 | # Git 命令一览 153 | 154 |

26 | ``` 27 | 28 | 另一个用户浏览了含有这个内容的页面将会跳转到 domain.com 并携带了当前作用域的 Cookie。如果这个论坛网站通过 Cookie 管理用户登录状态，那么攻击者就可以通过这个 Cookie 登录被攻击者的账号了。 29 | 30 | ## 危害 31 | 32 | - 窃取用户的 Cookie 33 | - 伪造虚假的输入表单骗取个人信息 34 | - 显示伪造的文章或者图片 35 | 36 | ## 防范手段 37 | 38 | ### 1. 设置 Cookie 为 HttpOnly 39 | 40 | 设置了 HttpOnly 的 Cookie 可以防止 JavaScript 脚本调用，就无法通过 document.cookie 获取用户 Cookie 信息。 41 | 42 | ### 2. 过滤特殊字符 43 | 44 | 例如将 `<` 转义为 `<`，将 `>` 转义为 `>`，从而避免 HTML 和 Jascript 代码的运行。 45 | 46 | ## 富文本编辑器 47 | 48 | 富文本编辑器允许用户输入 HTML 代码，就不能简单地将 `<` 等字符进行过滤了，极大地提高了 XSS 攻击的可能性。 49 | 50 | 富文本编辑器通常采用 XSS filter 来防范 XSS 攻击，通过定义一些标签白名单或者黑名单，从而不允许有攻击性的 HTML 代码的输入。 51 | 52 | 以下例子中，form 和 script 等标签都被转义，而 h 和 p 等标签将会保留。 53 | 54 | > [XSS 过滤在线测试](http://jsxss.com/zh/try.html) 55 | 56 | ```html 57 |

AND password=?"); 197 | stmt.setString(1, userid); 198 | stmt.setString(2, password); 199 | ResultSet rs = stmt.executeQuery(); 200 | ``` 201 | 202 | ### 2. 单引号转换 203 | 204 | 将传入的参数中的单引号转换为连续两个单引号，PHP 中的 Magic quote 可以完成这个功能。 205 | 206 | # 四、拒绝服务攻击 207 | 208 | 拒绝服务攻击（denial-of-service attack，DoS），亦称洪水攻击，其目的在于使目标电脑的网络或系统资源耗尽，使服务暂时中断或停止，导致其正常用户无法访问。 209 | 210 | 分布式拒绝服务攻击（distributed denial-of-service attack，DDoS），指攻击者使用两个或以上被攻陷的电脑作为“僵尸”向特定的目标发动“拒绝服务”式攻击。 211 | 212 | # 参考资料 213 | 214 | - [维基百科：跨站脚本](https://zh.wikipedia.org/wiki/%E8%B7%A8%E7%B6%B2%E7%AB%99%E6%8C%87%E4%BB%A4%E7%A2%BC) 215 | - [维基百科：SQL 注入攻击](https://zh.wikipedia.org/wiki/SQL%E8%B3%87%E6%96%99%E9%9A%B1%E7%A2%BC%E6%94%BB%E6%93%8A) 216 | - [维基百科：跨站点请求伪造](https://zh.wikipedia.org/wiki/%E8%B7%A8%E7%AB%99%E8%AF%B7%E6%B1%82%E4%BC%AA%E9%80%A0) 217 | - [维基百科：拒绝服务攻击](https://zh.wikipedia.org/wiki/%E9%98%BB%E6%96%B7%E6%9C%8D%E5%8B%99%E6%94%BB%E6%93%8A) 218 | -------------------------------------------------------------------------------- /notes/集群.md: -------------------------------------------------------------------------------- 1 | 2 | * [一、负载均衡](#一负载均衡) 3 | * [负载均衡算法](#负载均衡算法) 4 | * [转发实现](#转发实现) 5 | * [二、集群下的 Session 管理](#二集群下的-session-管理) 6 | * [Sticky Session](#sticky-session) 7 | * [Session Replication](#session-replication) 8 | * [Session Server](#session-server) 9 | 10 | 11 | 12 | # 一、负载均衡 13 | 14 | 集群中的应用服务器（节点）通常被设计成无状态，用户可以请求任何一个应用服务器。 15 | 16 | 负载均衡器会根据集群中每个节点的负载情况，将用户请求转发到合适的节点上。 17 | 18 | 负载均衡器可以用来实现高可用以及伸缩性： 19 | 20 | - 高可用：当某个节点故障时，负载均衡器会将用户请求转发到另外的节点上，从而保证所有服务持续可用； 21 | - 伸缩性：可以很容易地添加移除节点。 22 | 23 | 负载均衡运行过程包含两个部分： 24 | 25 | 1. 根据负载均衡算法得到请求转发的节点； 26 | 2. 将请求进行转发。 27 | 28 | ## 负载均衡算法 29 | 30 | ### 1. 轮询（Round Robin） 31 | 32 | 轮询算法把每个请求轮流发送到每个服务器上。 33 | 34 | 下图中，一共有 6 个客户端产生了 6 个请求，这 6 个请求按 (1, 2, 3, 4, 5, 6) 的顺序发送。(1, 3, 5) 的请求会被发送到服务器 1，(2, 4, 6) 的请求会被发送到服务器 2。 35 | 36 |

37 | 38 | 该算法比较适合每个服务器的性能差不多的场景，如果有性能存在差异的情况下，那么性能较差的服务器可能无法承担过大的负载（下图的 Server 2）。 39 | 40 |

41 | 42 | ### 2. 加权轮询（Weighted Round Robbin） 43 | 44 | 加权轮询是在轮询的基础上，根据服务器的性能差异，为服务器赋予一定的权值，性能高的服务器分配更高的权值。 45 | 46 | 例如下图中，服务器 1 被赋予的权值为 5，服务器 2 被赋予的权值为 1，那么 (1, 2, 3, 4, 5) 请求会被发送到服务器 1，(6) 请求会被发送到服务器 2。 47 | 48 |

49 | 50 | ### 3. 最少连接（least Connections） 51 | 52 | 由于每个请求的连接时间不一样，使用轮询或者加权轮询算法的话，可能会让一台服务器当前连接数过大，而另一台服务器的连接过小，造成负载不均衡。 53 | 54 | 例如下图中，(1, 3, 5) 请求会被发送到服务器 1，但是 (1, 3) 很快就断开连接，此时只有 (5) 请求连接服务器 1；(2, 4, 6) 请求被发送到服务器 2，只有 (2) 的连接断开，此时 (6, 4) 请求连接服务器 2。该系统继续运行时，服务器 2 会承担过大的负载。 55 | 56 |

57 | 58 | 最少连接算法就是将请求发送给当前最少连接数的服务器上。 59 | 60 | 例如下图中，服务器 1 当前连接数最小，那么新到来的请求 6 就会被发送到服务器 1 上。 61 | 62 |

63 | 64 | ### 4. 加权最少连接（Weighted Least Connection） 65 | 66 | 在最少连接的基础上，根据服务器的性能为每台服务器分配权重，再根据权重计算出每台服务器能处理的连接数。 67 | 68 |

69 | 70 | ### 5. 随机算法（Random） 71 | 72 | 把请求随机发送到服务器上。 73 | 74 | 和轮询算法类似，该算法比较适合服务器性能差不多的场景。 75 | 76 |

77 | 78 | ### 6. 源地址哈希法 (IP Hash) 79 | 80 | 源地址哈希通过对客户端 IP 计算哈希值之后，再对服务器数量取模得到目标服务器的序号。 81 | 82 | 可以保证同一 IP 的客户端的请求会转发到同一台服务器上，用来实现会话粘滞（Sticky Session） 83 | 84 |

85 | 86 | ## 转发实现 87 | 88 | ### 1. HTTP 重定向 89 | 90 | HTTP 重定向负载均衡服务器使用某种负载均衡算法计算得到服务器的 IP 地址之后，将该地址写入 HTTP 重定向报文中，状态码为 302。客户端收到重定向报文之后，需要重新向服务器发起请求。 91 | 92 | 缺点： 93 | 94 | - 需要两次请求，因此访问延迟比较高； 95 | - HTTP 负载均衡器处理能力有限，会限制集群的规模。 96 | 97 | 该负载均衡转发的缺点比较明显，实际场景中很少使用它。 98 | 99 |

100 | 101 | ### 2. DNS 域名解析 102 | 103 | 在 DNS 解析域名的同时使用负载均衡算法计算服务器 IP 地址。 104 | 105 | 优点： 106 | 107 | - DNS 能够根据地理位置进行域名解析，返回离用户最近的服务器 IP 地址。 108 | 109 | 缺点： 110 | 111 | - 由于 DNS 具有多级结构，每一级的域名记录都可能被缓存，当下线一台服务器需要修改 DNS 记录时，需要过很长一段时间才能生效。 112 | 113 | 大型网站基本使用了 DNS 做为第一级负载均衡手段，然后在内部使用其它方式做第二级负载均衡。也就是说，域名解析的结果为内部的负载均衡服务器 IP 地址。 114 | 115 |

116 | 117 | ### 3. 反向代理服务器 118 | 119 | 首先了解一下正向代理与反向代理的区别： 120 | 121 | - 正向代理：发生在客户端，是由用户主动发起的。比如翻墙，客户端通过主动访问代理服务器，让代理服务器获得需要的外网数据，然后转发回客户端； 122 | - 反向代理：发生在服务器端，用户不知道代理的存在。 123 | 124 | 反向代理服务器位于源服务器前面，用户的请求需要先经过反向代理服务器才能到达源服务器。反向代理可以用来进行缓存、日志记录等，同时也可以用来做为负载均衡服务器。 125 | 126 | 在这种负载均衡转发方式下，客户端不直接请求源服务器，因此源服务器不需要外部 IP 地址，而反向代理需要配置内部和外部两套 IP 地址。 127 | 128 | 优点： 129 | 130 | - 与其它功能集成在一起，部署简单。 131 | 132 | 缺点： 133 | 134 | - 所有请求和响应都需要经过反向代理服务器，它可能会成为性能瓶颈。 135 | 136 | ### 4. 网络层 137 | 138 | 在操作系统内核进程获取网络数据包，根据负载均衡算法计算源服务器的 IP 地址，并修改请求数据包的目的 IP 地址，最后进行转发。 139 | 140 | 源服务器返回的响应也需要经过负载均衡服务器，通常是让负载均衡服务器同时作为集群的网关服务器来实现。 141 | 142 | 优点： 143 | 144 | - 在内核进程中进行处理，性能比较高。 145 | 146 | 缺点： 147 | 148 | - 和反向代理一样，所有的请求和响应都经过负载均衡服务器，会成为性能瓶颈。 149 | 150 | ### 5. 链路层 151 | 152 | 在链路层根据负载均衡算法计算源服务器的 MAC 地址，并修改请求数据包的目的 MAC 地址，并进行转发。 153 | 154 | 通过配置源服务器的虚拟 IP 地址和负载均衡服务器的 IP 地址一致，从而不需要修改 IP 地址就可以进行转发。也正因为 IP 地址一样，所以源服务器的响应不需要转发回负载均衡服务器，可以直接转发给客户端，避免了负载均衡服务器的成为瓶颈。 155 | 156 | 这是一种三角传输模式，被称为直接路由，对于提供下载和视频服务的网站来说，直接路由避免了大量的网络传输数据经过负载均衡服务器。 157 | 158 | 这是目前大型网站使用最广负载均衡转发方式，在 Linux 平台可以使用的负载均衡服务器为 LVS（Linux Virtual Server）。 159 | 160 | 参考： 161 | 162 | - [Comparing Load Balancing Algorithms](http://www.jscape.com/blog/load-balancing-algorithms) 163 | - [Redirection and Load Balancing](http://slideplayer.com/slide/6599069/#) 164 | 165 | # 二、集群下的 Session 管理 166 | 167 | 一个用户的 Session 信息如果存储在一个服务器上，那么当负载均衡器把用户的下一个请求转发到另一个服务器，由于服务器没有用户的 Session 信息，那么该用户就需要重新进行登录等操作。 168 | 169 | ## Sticky Session 170 | 171 | 需要配置负载均衡器，使得一个用户的所有请求都路由到同一个服务器，这样就可以把用户的 Session 存放在该服务器中。 172 | 173 | 缺点： 174 | 175 | - 当服务器宕机时，将丢失该服务器上的所有 Session。 176 | 177 |

178 | 179 | ## Session Replication 180 | 181 | 在服务器之间进行 Session 同步操作，每个服务器都有所有用户的 Session 信息，因此用户可以向任何一个服务器进行请求。 182 | 183 | 缺点： 184 | 185 | - 占用过多内存； 186 | - 同步过程占用网络带宽以及服务器处理器时间。 187 | 188 | 189 |

190 | 191 | ## Session Server 192 | 193 | 使用一个单独的服务器存储 Session 数据，可以使用传统的 MySQL，也使用 Redis 或者 Memcached 这种内存型数据库。 194 | 195 | 优点： 196 | 197 | - 为了使得大型网站具有伸缩性，集群中的应用服务器通常需要保持无状态，那么应用服务器不能存储用户的会话信息。Session Server 将用户的会话信息单独进行存储，从而保证了应用服务器的无状态。 198 | 199 | 缺点： 200 | 201 | - 需要去实现存取 Session 的代码。 202 | 203 |

182 | 183 | # 五、缓存问题 184 | 185 | ## 缓存穿透 186 | 187 | 指的是对某个一定不存在的数据进行请求，该请求将会穿透缓存到达数据库。 188 | 189 | 解决方案： 190 | 191 | - 对这些不存在的数据缓存一个空数据； 192 | - 对这类请求进行过滤。 193 | 194 | ## 缓存雪崩 195 | 196 | 指的是由于数据没有被加载到缓存中，或者缓存数据在同一时间大面积失效（过期），又或者缓存服务器宕机，导致大量的请求都去到达数据库。 197 | 198 | 在存在缓存的系统中，系统非常依赖于缓存，缓存分担了很大一部分的数据请求。当发生缓存雪崩时，数据库无法处理这么大的请求，导致数据库崩溃。 199 | 200 | 解决方案： 201 | 202 | - 为了防止缓存在同一时间大面积过期导致的缓存雪崩，可以通过观察用户行为，合理设置缓存过期时间来实现； 203 | - 为了防止缓存服务器宕机出现的缓存雪崩，可以使用分布式缓存，分布式缓存中每一个节点只缓存部分的数据，当某个节点宕机时可以保证其它节点的缓存仍然可用。 204 | - 也可以进行缓存预热，避免在系统刚启动不久由于还未将大量数据进行缓存而导致缓存雪崩。 205 | 206 | ## 缓存一致性 207 | 208 | 缓存一致性要求数据更新的同时缓存数据也能够实时更新。 209 | 210 | 解决方案： 211 | 212 | - 在数据更新的同时立即去更新缓存； 213 | - 在读缓存之前先判断缓存是否是最新的，如果不是最新的先进行更新。 214 | 215 | 要保证缓存一致性需要付出很大的代价，缓存数据最好是那些对一致性要求不高的数据，允许缓存数据存在一些脏数据。 216 | 217 | # 六、数据分布 218 | 219 | ## 哈希分布 220 | 221 | 哈希分布就是将数据计算哈希值之后，按照哈希值分配到不同的节点上。例如有 N 个节点，数据的主键为 key，则将该数据分配的节点序号为：hash(key)%N。 222 | 223 | 传统的哈希分布算法存在一个问题：当节点数量变化时，也就是 N 值变化，那么几乎所有的数据都需要重新分布，将导致大量的数据迁移。 224 | 225 | ## 顺序分布 226 | 227 | 将数据划分为多个连续的部分，按数据的 ID 或者时间分布到不同节点上。例如 User 表的 ID 范围为 1 \~ 7000，使用顺序分布可以将其划分成多个子表，对应的主键范围为 1 \~ 1000，1001 \~ 2000，...，6001 \~ 7000。 228 | 229 | 顺序分布相比于哈希分布的主要优点如下： 230 | 231 | - 能保持数据原有的顺序； 232 | - 并且能够准确控制每台服务器存储的数据量，从而使得存储空间的利用率最大。 233 | 234 | # 七、一致性哈希 235 | 236 | Distributed Hash Table（DHT） 是一种哈希分布方式，其目的是为了克服传统哈希分布在服务器节点数量变化时大量数据失效的问题。 237 | 238 | ## 基本原理 239 | 240 | 将哈希空间 [0, 2n-1] 看成一个哈希环，每个服务器节点都配置到哈希环上。每个数据对象通过哈希取模得到哈希值之后，存放到哈希环中顺时针方向第一个大于等于该哈希值的节点上。 241 | 242 |

243 | 244 | 一致性哈希在增加或者删除节点时只会影响到哈希环中相邻的节点，例如下图中新增节点 X，只需要将它前一个节点 C 上的数据重新进行分布即可，对于节点 A、B、D 都没有影响。 245 | 246 |

247 | 248 | ## 虚拟节点 249 | 250 | 上面描述的一致性哈希存在数据分布不均匀的问题，节点存储的数据量有可能会存在很大的不同。 251 | 252 | 数据不均匀主要是因为节点在哈希环上分布的不均匀，这种情况在节点数量很少的情况下尤其明显。解决方式是通过增加虚拟节点，然后将虚拟节点映射到真实节点上。虚拟节点的数量比真实节点来得大，那么虚拟节点在哈希环上分布的均匀性就会比原来的真实节点好，从而使得数据分布也更加均匀。 253 | 254 | # 参考资料 255 | 256 | - 大规模分布式存储系统 257 | - [缓存那些事](https://tech.meituan.com/cache_about.html) 258 | - [一致性哈希算法](https://my.oschina.net/jayhu/blog/732849) 259 | - [内容分发网络](https://zh.wikipedia.org/wiki/%E5%85%A7%E5%AE%B9%E5%82%B3%E9%81%9E%E7%B6%B2%E8%B7%AF) 260 | - [How Aspiration CDN helps to improve your website loading speed?](https://www.aspirationhosting.com/aspiration-cdn/) 261 | -------------------------------------------------------------------------------- /notes/正则表达式.md: -------------------------------------------------------------------------------- 1 | 2 | * [一、概述](#一概述) 3 | * [二、匹配单个字符](#二匹配单个字符) 4 | * [三、匹配一组字符](#三匹配一组字符) 5 | * [四、使用元字符](#四使用元字符) 6 | * [五、重复匹配](#五重复匹配) 7 | * [六、位置匹配](#六位置匹配) 8 | * [七、使用子表达式](#七使用子表达式) 9 | * [八、回溯引用](#八回溯引用) 10 | * [九、前后查找](#九前后查找) 11 | * [十、嵌入条件](#十嵌入条件) 12 | * [参考资料](#参考资料) 13 | 14 | 15 | 16 | # 一、概述 17 | 18 | 正则表达式用于文本内容的查找和替换。 19 | 20 | 正则表达式内置于其它语言或者软件产品中，它本身不是一种语言或者软件。 21 | 22 | [正则表达式在线工具](https://regexr.com/) 23 | 24 | # 二、匹配单个字符 25 | 26 | **.** 可以用来匹配任何的单个字符，但是在绝大多数实现里面，不能匹配换行符； 27 | 28 | **.** 是元字符，表示它有特殊的含义，而不是字符本身的含义。如果需要匹配 . ，那么要用 \ 进行转义，即在 . 前面加上 \ 。 29 | 30 | 正则表达式一般是区分大小写的，但是也有些实现是不区分。 31 | 32 | **正则表达式** 33 | 34 | ``` 35 | nam. 36 | ``` 37 | 38 | **匹配结果** 39 | 40 | My **name** is Zheng. 41 | 42 | # 三、匹配一组字符 43 | 44 | **[ ]** 定义一个字符集合； 45 | 46 | 0-9、a-z 定义了一个字符区间，区间使用 ASCII 码来确定，字符区间在 [ ] 中使用。 47 | 48 | **-** 只有在 [ ] 之间才是元字符，在 [ ] 之外就是一个普通字符； 49 | 50 | **^** 在 [ ] 中是取非操作。 51 | 52 | **应用** 53 | 54 | 匹配以 abc 为开头，并且最后一个字母不为数字的字符串： 55 | 56 | **正则表达式** 57 | 58 | ``` 59 | abc[^0-9] 60 | ``` 61 | 62 | **匹配结果** 63 | 64 | 1. **abcd** 65 | 2. abc1 66 | 3. abc2 67 | 68 | # 四、使用元字符 69 | 70 | ## 匹配空白字符 71 | 72 | | 元字符 | 说明 | 73 | | :---: | :---: | 74 | | [\b] | 回退（删除）一个字符 | 75 | | \f | 换页符 | 76 | | \n | 换行符 | 77 | | \r | 回车符 | 78 | | \t | 制表符 | 79 | | \v | 垂直制表符 | 80 | 81 | \r\n 是 Windows 中的文本行结束标签，在 Unix/Linux 则是 \n。 82 | 83 | \r\n\r\n 可以匹配 Windows 下的空白行，因为它将匹配两个连续的行尾标签，而这正是两条记录之间的空白行； 84 | 85 | ## 匹配特定的字符类别 86 | 87 | ### 1. 数字元字符 88 | 89 | | 元字符 | 说明 | 90 | | :---: | :---: | 91 | | \d | 数字字符，等价于 [0-9] | 92 | | \D | 非数字字符，等价于 [^0-9] | 93 | 94 | ### 2. 字母数字元字符 95 | 96 | | 元字符 | 说明 | 97 | | :---: | :---: | 98 | | \w | 大小写字母，下划线和数字，等价于 [a-zA-Z0-9\_] | 99 | | \W | 对 \w 取非 | 100 | 101 | ### 3. 空白字符元字符 102 | 103 | | 元字符 | 说明 | 104 | | :---: | :---: | 105 | | \s | 任何一个空白字符，等价于 [\f\n\r\t\v] | 106 | | \S | 对 \s 取非 | 107 | 108 | \x 匹配十六进制字符，\0 匹配八进制，例如 \x0A 对应 ASCII 字符 10，等价于 \n。 109 | 110 | # 五、重复匹配 111 | 112 | - **\+** 匹配 1 个或者多个字符 113 | - **\** * 匹配 0 个或者多个 114 | - **?** 匹配 0 个或者 1 个 115 | 116 | **应用** 117 | 118 | 匹配邮箱地址。 119 | 120 | **正则表达式** 121 | 122 | ``` 123 | [\w.]+@\w+\.\w+ 124 | ``` 125 | 126 | [\w.] 匹配的是字母数字或者 . ，在其后面加上 + ，表示匹配多次。在字符集合 [ ] 里，. 不是元字符； 127 | 128 | **匹配结果** 129 | 130 | **abc.def@qq.com** 131 | 132 | - **{n}** 匹配 n 个字符 133 | - **{m, n}** 匹配 m\~n 个字符 134 | - **{m,}** 至少匹配 m 个字符 135 | 136 | \* 和 + 都是贪婪型元字符，会匹配最多的内容。在后面加 ? 可以转换为懒惰型元字符，例如 \*?、+? 和 {m, n}? 。 137 | 138 | **正则表达式** 139 | 140 | ``` 141 | a.+c 142 | ``` 143 | 144 | 由于 + 是贪婪型的，因此 .+ 会匹配更可能多的内容，所以会把整个 abcabcabc 文本都匹配，而不是只匹配前面的 abc 文本。用懒惰型可以实现匹配前面的。 145 | 146 | **匹配结果** 147 | 148 | **abcabcabc** 149 | 150 | # 六、位置匹配 151 | 152 | ## 单词边界 153 | 154 | **\b** 可以匹配一个单词的边界，边界是指位于 \w 和 \W 之间的位置；**\B** 匹配一个不是单词边界的位置。 155 | 156 | \b 只匹配位置，不匹配字符，因此 \babc\b 匹配出来的结果为 3 个字符。 157 | 158 | ## 字符串边界 159 | 160 | **^** 匹配整个字符串的开头，**$** 匹配结尾。 161 | 162 | ^ 元字符在字符集合中用作求非，在字符集合外用作匹配字符串的开头。 163 | 164 | 分行匹配模式（multiline）下，换行被当做字符串的边界。 165 | 166 | **应用** 167 | 168 | 匹配代码中以 // 开始的注释行 169 | 170 | **正则表达式** 171 | 172 | ``` 173 | ^\s*\/\/.*$ 174 | ``` 175 | 176 |

53 | 54 | # 四、良好的代码风格 55 | 56 | 适当的空行和缩进。 57 | 58 | 排列整齐的注释： 59 | 60 | ```java 61 | int a = 1; // 注释 62 | int b = 11; // 注释 63 | int c = 111; // 注释 64 | ``` 65 | 66 | 语句顺序不能随意，比如与 html 表单相关联的变量的赋值应该和表单在 html 中的顺序一致。 67 | 68 | # 五、为何编写注释 69 | 70 | 阅读代码首先会注意到注释，如果注释没太大作用，那么就会浪费代码阅读的时间。那些能直接看出含义的代码不需要写注释，特别是并不需要为每个方法都加上注释，比如那些简单的 getter 和 setter 方法，为这些方法写注释反而让代码可读性更差。 71 | 72 | 不能因为有注释就随便起个名字，而是争取起个好名字而不写注释。 73 | 74 | 可以用注释来记录采用当前解决办法的思考过程，从而让读者更容易理解代码。 75 | 76 | 注释用来提醒一些特殊情况。 77 | 78 | 用 TODO 等做标记： 79 | 80 | | 标记 | 用法 | 81 | |---|---| 82 | |TODO| 待做 | 83 | |FIXME| 待修复 | 84 | |HACK| 粗糙的解决方案 | 85 | |XXX| 危险！这里有重要的问题 | 86 | 87 | # 六、如何编写注释 88 | 89 | 尽量简洁明了： 90 | 91 | ```java 92 | // The first String is student's name 93 | // The Second Integer is student's score 94 | Map scoreMap = new HashMap<>(); 95 | ``` 96 | 97 | ```java 98 | // Student's name -> Student's score 99 | Map scoreMap = new HashMap<>(); 100 | ``` 101 | 102 | 添加测试用例来说明： 103 | 104 | ```java 105 | // ... 106 | // Example: add(1, 2), return 3 107 | int add(int x, int y) { 108 | return x + y; 109 | } 110 | ``` 111 | 112 | 使用专业名词来缩短概念上的解释，比如用设计模式名来说明代码。 113 | 114 | # 七、提高控制流的可读性 115 | 116 | 条件表达式中，左侧是变量，右侧是常数。比如下面第一个语句正确： 117 | 118 | ```java 119 | if (len < 10) 120 | if (10 > len) 121 | ``` 122 | 123 | 只有在逻辑简单的情况下使用 ? : 三目运算符来使代码更紧凑，否则应该拆分成 if / else； 124 | 125 | do / while 的条件放在后面，不够简单明了，并且会有一些迷惑的地方，最好使用 while 来代替。 126 | 127 | 如果只有一个 goto 目标，那么 goto 尚且还能接受，但是过于复杂的 goto 会让代码可读性特别差，应该避免使用 goto。 128 | 129 | 在嵌套的循环中，用一些 return 语句往往能减少嵌套的层数。 130 | 131 | # 八、拆分长表达式 132 | 133 | 长表达式的可读性很差，可以引入一些解释变量从而拆分表达式： 134 | 135 | ```python 136 | if line.split(':')[0].strip() == "root": 137 | ... 138 | ``` 139 | ```python 140 | username = line.split(':')[0].strip() 141 | if username == "root": 142 | ... 143 | ``` 144 | 145 | 使用摩根定理简化一些逻辑表达式： 146 | 147 | ```java 148 | if (!a && !b) { 149 | ... 150 | } 151 | ``` 152 | ```java 153 | if (!(a || b)) { 154 | ... 155 | } 156 | ``` 157 | 158 | # 九、变量与可读性 159 | 160 | **去除控制流变量** 。在循环中通过使用 break 或者 return 可以减少控制流变量的使用。 161 | 162 | ```java 163 | boolean done = false; 164 | while (/* condition */ && !done) { 165 | ... 166 | if ( ... ) { 167 | done = true; 168 | continue; 169 | } 170 | } 171 | ``` 172 | 173 | ```java 174 | while(/* condition */) { 175 | ... 176 | if ( ... ) { 177 | break; 178 | } 179 | } 180 | ``` 181 | 182 | **减小变量作用域** 。作用域越小，越容易定位到变量所有使用的地方。 183 | 184 | JavaScript 可以用闭包减小作用域。以下代码中 submit_form 是函数变量，submitted 变量控制函数不会被提交两次。第一个实现中 submitted 是全局变量，第二个实现把 submitted 放到匿名函数中，从而限制了起作用域范围。 185 | 186 | ```js 187 | submitted = false; 188 | var submit_form = function(form_name) { 189 | if (submitted) { 190 | return; 191 | } 192 | submitted = true; 193 | }; 194 | ``` 195 | 196 | ```js 197 | var submit_form = (function() { 198 | var submitted = false; 199 | return function(form_name) { 200 | if(submitted) { 201 | return; 202 | } 203 | submitted = true; 204 | } 205 | }()); // () 使得外层匿名函数立即执行 206 | ``` 207 | 208 | JavaScript 中没有用 var 声明的变量都是全局变量，而全局变量很容易造成迷惑，因此应当总是用 var 来声明变量。 209 | 210 | 变量定义的位置应当离它使用的位置最近。 211 | 212 | **实例解析** 213 | 214 | 在一个网页中有以下文本输入字段： 215 | 216 | ```html 217 | 218 | 219 | 220 | 221 | ``` 222 | 223 | 现在要接受一个字符串并把它放到第一个空的 input 字段中，初始实现如下： 224 | 225 | ```js 226 | var setFirstEmptyInput = function(new_alue) { 227 | var found = false; 228 | var i = 1; 229 | var elem = document.getElementById('input' + i); 230 | while (elem != null) { 231 | if (elem.value === '') { 232 | found = true; 233 | break; 234 | } 235 | i++; 236 | elem = document.getElementById('input' + i); 237 | } 238 | if (found) elem.value = new_value; 239 | return elem; 240 | } 241 | ``` 242 | 243 | 以上实现有以下问题： 244 | 245 | - found 可以去除； 246 | - elem 作用域过大； 247 | - 可以用 for 循环代替 while 循环； 248 | 249 | ```js 250 | var setFirstEmptyInput = function(new_value) { 251 | for (var i = 1; true; i++) { 252 | var elem = document.getElementById('input' + i); 253 | if (elem === null) { 254 | return null; 255 | } 256 | if (elem.value === '') { 257 | elem.value = new_value; 258 | return elem; 259 | } 260 | } 261 | }; 262 | ``` 263 | 264 | # 十、抽取函数 265 | 266 | 工程学就是把大问题拆分成小问题再把这些问题的解决方案放回一起。 267 | 268 | 首先应该明确一个函数的高层次目标，然后对于不是直接为了这个目标工作的代码，抽取出来放到独立的函数中。 269 | 270 | 介绍性的代码： 271 | 272 | ```java 273 | int findClostElement(int[] arr) { 274 | int clostIdx; 275 | int clostDist = Interger.MAX_VALUE; 276 | for (int i = 0; i < arr.length; i++) { 277 | int x = ...; 278 | int y = ...; 279 | int z = ...; 280 | int value = x * y * z; 281 | int dist = Math.sqrt(Math.pow(value, 2), Math.pow(arr[i], 2)); 282 | if (dist < clostDist) { 283 | clostIdx = i; 284 | clostDist = value; 285 | } 286 | } 287 | return clostIdx; 288 | } 289 | ``` 290 | 291 | 以上代码中循环部分主要计算距离，这部分不属于代码高层次目标，高层次目标是寻找最小距离的值，因此可以把这部分代替提取到独立的函数中。这样做也带来一个额外的好处有：可以单独进行测试、可以快速找到程序错误并修改。 292 | 293 | ```java 294 | public int findClostElement(int[] arr) { 295 | int clostIdx; 296 | int clostDist = Interger.MAX_VALUE; 297 | for (int i = 0; i < arr.length; i++) { 298 | int dist = computDist(arr, i); 299 | if (dist < clostDist) { 300 | clostIdx = i; 301 | clostDist = value; 302 | } 303 | } 304 | return clostIdx; 305 | } 306 | ``` 307 | 308 | 并不是函数抽取的越多越好，如果抽取过多，在阅读代码的时候可能需要不断跳来跳去。只有在当前函数不需要去了解某一块代码细节而能够表达其内容时，把这块代码抽取成子函数才是好的。 309 | 310 | 函数抽取也用于减小代码的冗余。 311 | 312 | # 十一、一次只做一件事 313 | 314 | 只做一件事的代码很容易让人知道其要做的事； 315 | 316 | 基本流程：列出代码所做的所有任务；把每个任务拆分到不同的函数，或者不同的段落。 317 | 318 | # 十二、用自然语言表述代码 319 | 320 | 先用自然语言书写代码逻辑，也就是伪代码，然后再写代码，这样代码逻辑会更清晰。 321 | 322 | # 十三、减少代码量 323 | 324 | 不要过度设计，编码过程会有很多变化，过度设计的内容到最后往往是无用的。 325 | 326 | 多用标准库实现。 327 | 328 | # 参考资料 329 | 330 | - Dustin, Boswell, Trevor, 等. 编写可读代码的艺术 [M]. 机械工业出版社, 2012. 331 | --------------------------------------------------------------------------------
