  2 | 
  3 | > 在React上集成Sentry的demo
  4 | 
  5 | ## 文件说明:
  6 | 
  7 | ### `scripts/transform-release.js`
  8 | 
  9 | 因为上传`source-map`到`Sentry`，需要`release`字段信息才可以。这个字段可以把它理解成`package.json`里的`version`字段。意思差不多
 10 | 
 11 | 这个文件就是把`package.json`里的`release`字段保存成json文件，文件在`src`目录下。
 12 | 
 13 | src目录下有代码需要`release`字段，但是因为限制，而不能使用`import`或者`require`去引入不在src目录下的文件。所以需要把文件放在src目录下，方便去调用。打包时会把这个文件的内容打包到最终的js文件里。其实src下的代码是可以去引入根目录的package.json的文件的，但是这样一来会把整个package.json打包到最终js文件里。这样会导致项目上线时，对外暴露了整个package.json的内容。所以写了需要这个文件把package.json里的`release`字段保存成一个json文件，相当于一个中间件的作用。避免之前所说的问题。同时也减少了最终打包的大小。
 14 | 
 15 | 这个文件会被`package.json`里的`scripts`里的`build:sentry`去调用。调用命令为: `npm run build:sentry`
 16 | 
 17 | 生成的json文件分别被`scripts/post-sym.js`和`src/index.js`文件去引用。
 18 | 
 19 | ### `scripts/post-sym.js`
 20 | 
 21 | 此文件用于上传source-map文件到sentry服务器上。
 22 | 
 23 | 上传之后，会把source-map文件删除，防止在项目上线后，source-map文件泄露。
 24 | 
 25 | 这个文件会对当前的环境进行检查，看是否有什么意外情况导致无法上传。
 26 | 
 27 | ### `sentry.properties`
 28 | 
 29 | 此文件为`sentry`的配置文件，用于上传的验证和最终上传到`sentry`的哪个项目下。
 30 | 
 31 | ```ini
 32 | defaults.url  # 为sentry的服务器，如果不写，默认就是https://sentry.io/。如果公司内网有搭建此项目，这里把地址更换下就好。
 33 | defaults.org  # 如果项目属于某一个team下，那就填写此team的名称
 34 | defaults.project  # 项目的名称
 35 | auth.token # 验证的token，需要保证此token具有以下权限: project:read、project:write、project:releases
 36 | ```
 37 | 
 38 | ### `src/SentryBoundary.js`
 39 | 
 40 | 此组件用于捕获错误，并把错误发送到sentry服务器。这个和之前的`scripts/post-sym.js`做的两件事情，不要搞混。
 41 | 
 42 | 此组件，是把捕获到的错误，发送到sentry服务器，但是发送到服务器的时候，js已经被混淆加密过了。所以需要`scripts/post-sym.js`文件去上传source-map，这样在`sentry`看的时候，就能准确的定位到错误的位置。下面是不上传source-map文件和上传`source-map`后的截图对比：
 43 | 
 44 | ![image](https://user-images.githubusercontent.com/8198408/43457174-9945b152-94f8-11e8-9aca-e8ab4069444f.png)
 45 | 
 46 | ![image](https://user-images.githubusercontent.com/8198408/43457143-823175d2-94f8-11e8-8140-f4e04708ad7e.png)
 47 | 
 48 | 此组件需要放在`React`的组件最外面，代码如下:
 49 | 
 50 | ```javascript
 51 | ReactDOM.render(
 52 |   <div>
 53 |     <SentryBoundary>
 54 |       <App />
 55 |     </SentryBoundary>
 56 |   </div>,
 57 |   document.getElementById("root")
 58 | );
 59 | ```
 60 | 
 61 | ## 流程说明:
 62 | 
 63 | ### 编写sentry.properties
 64 | 
 65 | 首先你去sentry申请一个[API keys](https://sentry.io/settings/account/api/auth-tokens/)。保证其具有以下权限: project:read、project:write、project:releases。
 66 | 
 67 | 打开你的项目，记录下url地址。如: `https://sentry.io/black-hole-m9/react/`，这里的`black-hole-9`就是org，`react`就是project。
 68 | 
 69 | 根据以上信息，我们编写`sentry.properties`文件内容如下：
 70 | 
 71 | ```ini
 72 | defaults.url=https://sentry.io/
 73 | defaults.org=black-hole-m9
 74 | defaults.project=react
 75 | auth.token=ac1c75ca4f6b4c77a47c9b15dee8dfab86fce6fc4f484363a63e9d29f0bf6572
 76 | ```
 77 | 
 78 | ### 获取release
 79 | 
 80 | 前文也说道，sentry上传source-map需要`release`字段信息。现在我们可以确定的是这个信息，会被两处地方调用。
 81 | 
 82 | 一次是上传的时候，告知sentry当前的`release`。一次是应用初始化捕获错误的时候，告知错误发到哪个`release`。这样一来，错误和source-map就可以对应上了。
 83 | 
 84 | 所以根据上面的需求，编写了`scripts/transform-release.js`。同时在package.json里的scripts对象上增加了一条: `"transform-release": "node scripts/transform-release.js"`
 85 | 
 86 | *如果不是要上传source-map，而是上传PDB、SYM、dSYM等Symbols link(Debug Information Files)，那不需要source-map，其上传命令也是不一样。*
 87 | 
 88 | ### 编写组件
 89 | 
 90 | 因为我们要捕获错误，在纯JavaScript里(不含框架)的Web应用中，sentry的做法是重写`window.onerror`来达到捕获错误的功能，但是在`React`中，却不一样。需要增加一个组件，其组件在最外层。
 91 | 
 92 | 组件的代码其实很简单，通过`componentDidCatch`来监听所有子组件的catch。然后可以通过返回一个`render`，来替换掉崩溃的组件。具体的例子可以见: [Example](https://wiggly-power.glitch.me/)，[Example源码](https://glitch.com/edit/#!/wiggly-power)
 93 | 
 94 | ### 重写window.error
 95 | 
 96 | 这里的重写并不是指我们来重新，sentry已经帮我们做好了，我们只需要去调用他的方法就好了。
 97 | 
 98 | 我们打开应用的入口文件，也就是`src/index.js`，在里面通过`import Raven from "raven-js"`去引入`sentry`的包，再使用：`Raven.config(/** 配置 **/).install()`就好了
 99 | 
100 | 如果你没有跳过上面的部分，那你应该知道，这里就要需要`release`字段了。在`config`里，增加一个`release`字段，通过引入我们之前生成的json文件去获取
101 | 
102 | ### 上传source-map
103 | 
104 | 这里一定要开启生成source-map的选项。不然会报错的。上传的的命令其实就是下面这样:
105 | 
106 | ```sh
107 | sentry-cli releases new {releases字段值}
108 | sentry-cli releases files {releases字段值} upload-sourcemaps {js文件和js.map所在目录。如果没有找到，sentry会遍历其子目录} --url-prefix '~/{过滤规则}'`;
109 | ```
110 | 
111 | 这里需要注意的地方是`--url-prefix`这个字段，你可以把它想象成nginx的location。
112 | 
113 | 这里假设过滤规则如下: `~/static/js/` 当打开网站访问时，请求js的url地址为:`xxx.com/static/js/js文件名.js`时，就会匹配成功，当是`xxx.com/aa/js/js文件名.js`时，将不会匹配。
114 | 
115 | 我把这个些操作写成一个js脚本，让其自动化。其中包含环境检测、认证检测、上传source-map、删除本地source-map。
116 | 
117 | 这个脚本就是`srcipts/post-sym.js`，同时在package.json里的scripts对象上增加了一条:
118 |  `"post-sym": "cross-env NODE_ENV=production SENTRY_PROPERTIES=./sentry.properties node scripts/post-sym.js"`
119 | 
120 |  `NODE_ENV`这个需要是因为其文件里调用了webpack配置，如果不调用则会报错，`SENTRY_PROPERTIES`则是告知我们的sentry配置。
121 | 
122 |  ### 终章
123 | 
124 |  现在我们把上面的`npm script`统一一下，成为新的`npm script`:
125 |  `"build:sentry": "npm run transform-release && npm run build && npm run post-sym"`
126 | 
127 |  这样，以后我们写完代码，就可以通过`npm run build:sentry`来自动化了。后续的版本迭代，只需要修改`package.json`里的`releases`就好。
