错误类型讲解:异常与监控
项目接入
前端
Vue
yarn add @sentry/vue @sentry/tracing更详细的请查看 官网文档
2.x
import Vue from "vue";import Router from "vue-router";import * as Sentry from "@sentry/vue";import { Integrations } from "@sentry/tracing";Vue.use(Router);const router = new Router({// ...});Sentry.init({Vue,dsn: "https://138b35a0c5584646944565b51fa8a3f3@o1064497.ingest.xxxx.io/6055444",integrations: [new Integrations.BrowserTracing({routingInstrumentation: Sentry.vueRouterInstrumentation(router),tracingOrigins: ["localhost", "my-site-url.com", /^\//],}),],// Set tracesSampleRate to 1.0 to capture 100%// of transactions for performance monitoring.// We recommend adjusting this value in productiontracesSampleRate: 1.0,// 添加用户崩溃反馈弹窗beforeSend(event, hint) {// Check if it is an exception, and if so, show the report dialogif (event.exception) {Sentry.showReportDialog({ eventId: event.event_id });}return event;},});// ...new Vue({router,render: h => h(App),}).$mount("#app");
3.x

React
yarn add @sentry/react @sentry/tracing
umijs创建项目在app.ts中初始化sentry.init配置 更详细的请查看 官网文档
import React from "react";import ReactDOM from "react-dom";import * as Sentry from "@sentry/react";import { Integrations } from "@sentry/tracing";import App from "./App";Sentry.init({dsn: "https://138b35a0c5584646944565b51fa8a3f3@o1064497.ingest.sentry.io/6055459",integrations: [new Integrations.BrowserTracing()],// Set tracesSampleRate to 1.0 to capture 100%// of transactions for performance monitoring.// We recommend adjusting this value in productiontracesSampleRate: 1.0,});ReactDOM.render(<App />, document.getElementById("root"));// Can also use with React Concurrent Mode// ReactDOM.createRoot(document.getElementById('root')).render(<App />);
主动上报错误
有时候我们觉得它是个错误,但是sentry没这么认为,所以需要主动上报,这里sentry提供两个 API(captureException 与 captureMessage)
captureException:主动上报错误,这会触发系统内部钩子(webhooks) captureMessage:可以理解为埋点,不会触发系统内部钩子(webhooks),这里的 level: info
import * as Sentry from '@sentry/vue';export type ISentry = typeof Sentry;class TrackError {public sentry?: ISentry;constructor(sentry?: ISentry) {this.sentry = sentry;}captureException(exception: any) {if (!this.sentry || !exception) return;this.sentry.captureException(exception);}}export default TrackError;
SourceMap
官网有三种做法如下:
- sentry 提供
webpack-plugin(链接)- 脚手架工具
sentry-cli- 直接调用
sentry API(有点麻烦,参数配置有点多)这里介绍 @sentry/webpack-plugin 方式(方便接入现有 CI/CD)
.sentryclirc
[auth]token=42b21a34ca654530af08 授权令牌,认证凭证token(Settings/Auth Tokens)[defaults]url = https://sentry.io/ 上报 sentry 地址org = ws-ap 组织名称(Organization)project = qv-h5 项目名称
vue.config.js
const SentryCliPlugin = require('@sentry/webpack-plugin');module.exports = {// 开启 source mapproductionSourceMap: true,configureWebpack: config => {config.plugins.push(new SentryCliPlugin({include: './dist/',configFile: 'sentry.properties',// 版本(如果没有指定,sentry会自动创建 string 类型版本号),记得跟 init 版本一致sourceMap才会生效release: process.env.VUE_APP_PROJECT_RELEASE,ignore: ['node_modules'],urlPrefix: `${process.env.VUE_APP_COS_URL}/`}))}};
Tips
urlPrefix可以为上传的map文件添加前缀,默认是~/,sentry需要根据js文件的sourceMappingURL来解析map文件路径,所以SourceMap级别不能用hide-source-map或者类似的。
很多人反馈错误没有定位到源码,很多就是错在这个配置(urlPrefix),这里解释下,
关于这个,是要看你项目的资源地址,比如,你前端访问页面是:http://test.com.cn/test/login,同时你的资源地址是:http://test.com.cn/test/dist/js/app.ecbb420f.js,那么,配置就应该是(urlPrefix)~/test/(注意:非ip地址test)。
怎么看资源地址呢, 例如谷歌浏览器, F12控制台, 或者去 Application 里面找到对应资源打开。例如下图
再或者, 打开你的项目看看 build 下打的 assetsPublicPath 是什么,如果是:assetsPublicPath: '/test/',那你的 urlPrefix: '~/test/' 就是这个, 如果是 '/' ,那可以不配置,采用默认('~/')的即可。
