官方`eosio.token`合约的`transfer`方法，`memo`被断言为长度小于等于`256`（`eosio_assert( memo.size() <= 256, "memo has more than 256 bytes" )`），那么作为一名“专业”码农应该觉得可以输入纯英文字符最多`256`个，纯汉字减半，然鹅在链上跑的时候，并不是酱紫的。 5 | 6 | ## 敲黑板： 7 | 在链上跑的时候，纯汉字最多可以输入`85`个，纯英文字符可以输入`258`个。每个汉字占用`length`为`3`。 8 | -------------------------------------------------------------------------------- /eosio的history插件自定义过滤/README.md:

修改完后回到`eosio`源码根目录，执行`./eosio_build.sh`。使用该`build`出来的`nodeos`启动，启动后通过`cleos get actions eosio.token`查看。 49 | -------------------------------------------------------------------------------- /eosio的mongo插件的使用/README.md: -------------------------------------------------------------------------------- 1 | ## eosio提供了mongo插件，实现把数据导到mongo中，从而可以更加灵活的操作数据。 2 | ## 配置（config.ini） 3 | ``` 4 | plugin = eosio::mongo_db_plugin 5 | mongodb-uri = mongodb://localhost:27017 6 | ``` 7 | ## 本地启动mongo 8 | ``` 9 | $ sudo mongod 10 | ``` 11 | ## 重启nodeos 12 | ``` 13 | $ nodeos --replay-blockchain --hard-replay-blockchain --mongodb-wipe 14 | ``` 15 | ## mongo中查询 16 | ``` 17 | $ mongo 18 | > show dbs 19 | EOS 0.372GB 20 | ... 21 | 22 | > use EOS 23 | switched to db EOS 24 | 25 | > show tables 26

-------------------------------------------------------------------------------- /eosio的快照功能/README.md: -------------------------------------------------------------------------------- 1 | EOS Snapshot可以帮助Nodeos快速的恢复数据 2 | ## 一、配置(在config.ini中) 3 | ``` 4 | // 配置保存snapshot的路径 5 | snapshots-dir = "snapshots" 6 | 7 | // 插件 8 | plugin = eosio::chain_api_plugin 9 | plugin = eosio::chain_plugin 10 | plugin = eosio::net_plugin 11 | plugin = eosio::producer_api_plugin 12 | ``` 13 | ## 二、重启nodeos 14 | ## 三、创建snapshot 15 | ``` 16 | // 下面将会在snapshots-dir下生成一个head_block_id的bin文件 17 | $ curl http://127.0.0.1:8888/v1/producer/create_snapshot 18 | ``` 19 | ## 从快照恢复数据 20 | ``` 21 | // 删除data下除blocks/blocks.log的其他文件 22 | // 启动nodeos的时候添加--snapshot参数，指定snapshot文件路径 23 | $ nodeos --snapshot + snapshot path 24 | ``` 25 | -------------------------------------------------------------------------------- /eosio获取账号actions/README.md: -------------------------------------------------------------------------------- 1 | ## 概述： 2 | 有时候我们使用别人的 rpc 地址，`get actions`的时候返回的是空： 3 | ``` 4 | $: cleos -u https://别人的rpc.io get actions myaccount111 5 | # seq when contract::action => receiver trx id... args 6 | ================================================================================================================ 7 | ``` 8 | 9 | 这是因为，你使用的这个别人的 rpc 地址，他的 nodeos 没有打开`filter-on`配置，或者他只开了他需要监听的账号和 action ，这个时候，你就要另找 rpc 地址了。 10 | 11 | ## 配置自己的节点： 12 | 如果你有自己的节点，你想用自己节点的 rpc 查找 actions ，应该怎么配置呢？ 13 | 当然，你可以在 `config.ini` 配置文件中，设置 `filter-on = *` ，这样会记录全网的所有账号，以及所有的 actions ，但是你要认识到这需要很大的服务器物理内存。 14 | 如果你只需要记录账号`myaccount111`的`transfer`，你只用这样配置就好了：`filter-on = myaccount111::transfer`。 15 | -------------------------------------------------------------------------------- /eosio计算ram价格/README.md: -------------------------------------------------------------------------------- 1 | ## 首先获取多索引表`rammarket`的数据： 2 | ``` 3 | $: cleos -u https://nodes.get-scatter.com:443 get table eosio eosio rammarket 4 | { 5 | "rows": [{ 6 | "supply": "10000000000.0000 RAMCORE", 7 | "base": { 8 |

false 18 | } 19 | ``` 20 | 21 | ## 那么`n KB`的内存价格为： 22 | ``` 23 | n KB内存需要的EOS = ( n * quote.balance ) / ( n + base.balance / 1024 ) 24 | -------------------------------------------------------------------------------- /eosio通过插件存储账号余额到mongo/README.md: -------------------------------------------------------------------------------- 1 | ## 通过mongo_db_plugin存储账号余额到mongodb 2 | 3 | 我们这里以存储`eosio.token`的`EOS`余额为例，思路是在发生`transfer`的时候，我们捕获该`action`，然后更新双方的余额。 4 | 5 | 首先，在`class mongo_db_plugin_impl`中声明我们需要的变量和函数 6 | ``` 7 | static const std::string accounts_col; 8 | static const std::string pub_keys_col; 9 | static const std::string account_controls_col; 10 | + 11 | + // for get currency balance 12 | + mongocxx::collection _currency_balance; // mongo集合的handle 13 | + static const std::string currency_balance_col; // 将存放mongo集合的名称 14 | + chain_plugin* chain_plug_handle; // chain_plugin 中 get_currency_balance 可以帮助我们获取余额信息 15 | + void update_currency_balance( const chain::action_trace& ); // 我们的操作放到这里进行 16 | ``` 17 | 18 | 给集合取名为`currency_balance` 19 | ``` 20 | const std::string mongo_db_plugin_impl::account_controls_col = "account_controls"; 21 | +const std::string mongo_db_plugin_impl::currency_balance_col = "currency_balance"; // mongo中集合将显示的是这个 22 | ``` 23 | 24 | 在`mongo_db_plugin_impl::consume_blocks`中初始化`handle`

| EOS 中，合约的`action`对应合约 C++ 代码中的一个函数，如果你认为这个函数可以像传统 C++ 编码那样命名，那就错了。因为对应合约的`action`，所以有一些规则限制。 3 | 4 | ## 出错： 5 | 如果编译或执行合约的某个`action`，出现以下提示，说明`action`对应的函数命名不合规范： 6 | ``` 7 | Name should be less than 13 characters and only contains the following symbol .12345abcdefghijklmnopqrstuvwxyz 8 | ``` 9 | 10 | ## 规范： 11 | 从`出错`提示知道，`action`对应的函数名，长度不能超过`12`个字符，并且只能由`.12345abcdefghijklmnopqrstuvwxyz`这些字符组成。 12 | -------------------------------------------------------------------------------- /lnmp/lnmp迁移.md: -------------------------------------------------------------------------------- 1 | ## LNMP(Linux Nginx Mysql PHP) 2 | ### LNMP官网：[https://lnmp.org/](https://lnmp.org/) 3 | ### 这里记录一下LNMP部署的站点从云服务器A迁移到云服务器B的过程，服务器的系统为Ubuntu 16.04 64位，LNMP1.5 4 | - 首先，使用LNMP搭建的网站根站点一般在`/home/wwwroot`下，默认站点目录是`default`(通过`/usr/local/nginx/conf/nginx.conf`可知)，`default`里面还有一个`phpmyadmin`目录，由此，大概你能猜到能做什么了(由于安全问题，`default`和`phpmyadmin`可能已被重命名，这样就能禁止通过网页访问`phpmyadmin`等)。 5 | - 因为`Nginx`可以为同一`IP`绑定多个域名，所以`/home/wwwroot`下除了`default`应该还有别的站点目录。在对应站点目录找到数据库账号和密码。 6 | - 通过浏览器使用`IP`访问，这时访问的应该是`/home/wwwroot/default`，页面上有`探针`、`phpinfo`、`phpMyadmin`等功能链接。 7 | - 通过`phpMyadmin`导出数据库。 8 | - 使用`探针`查看站点`Mysql`数据库、`PHP`模块、`LNMP`的版本。 9 | - 到`LNMP`[官网](https://lnmp.org/)下载对应的版本。 10 | - 按照官网[安装](https://lnmp.org/install.html)教程进行安装，安装过程中选择对应的`Mysql`、`PHP`版本。 11 | - 安装完成后通过`IP`访问看是否出现`LNMP`页面。然后通过`phpMyadmin`创建数据库账号，并且导入数据库，设置数据库拥有者权限。 12 | - 打包网站代码，并上传至新的服务器对应的站点目录下。 13 | - 如果`Nginx`有绑定多域名，则打包原服务器`/usr/local/nginx/conf`下的`vhost`，并上传到新的站点服务器相应目录下。 14 | - `sudo /etc/init.d/nginx restart`重启服务，然后通过域名访问网站。 15 | ### 踩坑 16 | 如果网站是基于`thinkphp`等一些框架的，这时候通过域名访问可能返回的是`500`错误。这个问题的原因很可能是由于`LNMP`的防跨域引起的。 17 | 根据[这里](https://lnmp.org/faq/lnmp-vhost-add-howto.html)的说法，在`thinkphp`、`codeigniter`、`laravel`等框架下，网站目录一般是在`public`下，但 18 | 是`public`下的程序要跨目录调用`public`上级目录下的文件，因为`LNMP`默认是不允许跨目录访问的，所以都是必须要将防跨目录访问的设置去掉：`LNMP 1.4`或以上将 `/usr/local/nginx/conf/fastcgi.conf`里面的`fastcgi_param PHP_ADMIN_VALUE "open_basedir=$document_root/:/tmp/:/proc/"`这一行删除或在行首添加 19 | `#`号注释掉，然后`sudo /etc/init.d/nginx restart`重启`Nginx`服务。 -------------------------------------------------------------------------------- /mongodb简单使用/README.md: -------------------------------------------------------------------------------- 1 | ## MongoDB简介 2 | MongoDB是一个基于分布式文件存储，介于关系型和非关系型的数据库。 3 | 今天我们通过第三方平台（如Google等）可以很轻易地访问和抓取用户数据。用户的个人信息、社交网络、地理位置，用户生成的数据和用户操作日子已经成倍的增加。我们如果要对这些数据挖掘，那SQL数据库已经不适合这些应用了，NoSQL(即No Only SQL，MongoDB就是这种类型的数据库之一)数据库的发展却能很好的处理这些大数据。 4 | MongoDB将数据存储为一个文档，数据结构有键值对(key=>value)组成，类似于JSON对象，MongoDB中叫BSON(即序列化的二进制JSON)。 5 | ## MacOS平台安装MongoDB 6 | 官网提供了安装包：[https://www.mongodb.com/download-center#community](https://www.mongodb.com/download-center#community)； 7 | 也可以通过brew进行安装: 8 | ``` 9 | $ sudo brew install mongodb 10 | 11 | // 安装支持 TLS/SSL 命令 12 | $ sudo brew install mongodb --with-openssl 13 | 14 | // 安装最新开发版本 15 | $sudo brew install mongodb --devel 16 | ``` 17 | ## MongoDB操作 18 | #### 运行 19 | ``` 20 | // 创建一个数据库存储目录 21 | $ sudo mkdir -p /data/db 22 | 23 | // 启动 mongodb，默认数据库目录即为 /data/db 24 | $ sudo mongod 25 | 26 | // 打开另一个终端连接刚启动的mongod服务 27 | $ mongo 28 | ``` 29 | #### 操作(启动mongo连接数据库服务后) 30 | ##### 显示数据库 31 | ``` 32 | // 显示所有数据库列表 33 | > show dbs 34 | 35 | // 显示当前的数据库或集合 36 | > db 37 | ``` 38 | ##### 使用mytest数据库，如果不存在则新建 39 | `> use mytest` 40 | ##### 删除mytest数据库 41 | ``` 42 | > use mytest 43 | > db.dropDatabase() 44 | ``` 45 | ##### 创建集合 46 | ``` 47 | // 在test数据库上创建一个叫kk的集合 48 | > use test 49 | > db.createCollection("kk") 50 | 51 | // 或者插入数据的时候，也会自动创建集合 52 | > db.kk.insert({"name" : "hhily"}) 53 | ``` 54 | ##### 查看集合 55 | `> show collections` 56 | ##### 删除集合 57 | ``` 58 | // 删除test数据库中叫kk的集合 59 | > use test 60 | > db.kk.drop() 61 | ``` 62 | ##### 插入文档 63 | ``` 64 | // 在runoob数据库col集合中插入一条文档 65 | > use runoob 66 | > db.col.insert({title: 'MongoDB 教程', 67 | description: 'MongoDB 是一个 Nosql 数据库', 68 | by: '菜鸟教程', 69 | url: 'http://www.runoob.com', 70 | tags: ['mongodb', 'database', 'NoSQL'], 71 | likes: 100 72 | }) 73 | // 上面的插入中，如果col集合不存在，将新建 74 | ``` 75 | ##### 查询文档 76 | ``` 77 | > db.col.find().pretty() 78 | // or 79 | > db.col.findOne().pretty() 80 | ``` 81 | ##### 更新文档 82 | `> db.col.updateOne({'title':'MongoDB 教程'},{$set:{'title':'MongoDB'}})` 83 | ##### 删除文档 84 | `db.col.deleteMany({'title':'MongoDB 教程'})` 85 |

react-intl 是一个语言本地化的库 2 | *我们可以通过配置 `json` 文件或 `js` 文件实现多语言切换，可以还在用这么 `low` 的方法真的有钱途嘛~* 3 | *比如中文的货币符号是 '￥'，英文是 '$'，这些通过配置 `react-intl` 都能自动帮我们处理好。* 4 | ### 仓库地址：[https://github.com/yahoo/react-intl](https://github.com/yahoo/react-intl) 5 | `react-intl` 可以使用组件的方式，或 `api` 的方式进行语言本地化。推荐使用组件的方式，只有在组件方式不可用时（比如使用 `antd` 的`message`输出提示消息时），才选择使用 `api` 的方式。 6 |
