React应用上的Google Analytics（分析）不起作用 [英] Google Analytics on React app doesn't work

问题描述

我将我的投资组合（仍在开发中）托管在github页面上。它只是一个包含静态内容的网络应用。而且我需要将Google Analytics（分析）添加到我的投资组合中并获得访问次数（主要是为了熟悉该过程）。我发现了 react-ga 模块，该模块可用于在React Apps上配置Google Analytics（分析） （使用create-react-app创建）。

I hosted my portfolio (which is still under development) on github pages. It's just a web app with static content. And I needed to add Google Analytics to my portfolio and get the number of visits (mainly to get familiar with the process). I found out react-ga module which can be used to configure Google Analytics on React Apps (which created using create-react-app).

然后跟随此教程，并对其进行配置和托管。我用测试流量检查了该网站，但Google Analytics（分析）信息中心没有更新。可能是什么情况？它应该根据教程工作。由于我是 Google Analytics（分析）的新手，所以我很难找出问题所在。

And followed this tutorial and configured it and hosted. And I checked the site with test traffic but Google Analytics dashboard doesn't update. What maybe the case ? It should work according to the tutorial. As I'm new to Google Analytics it's hard for me to figure out the issue.

这是我的 App.js

import React, { Component } from "react";
import HeaderList from "./components/Header";
import "./App.css";
import { Layout } from "antd";
import { Router, Route, Switch } from "react-router-dom";
import createHistory from "history/createBrowserHistory";
import ReactGA from 'react-ga';
import Keys from './config/keys';

import AboutMe from "./components/AboutMe";
import Skills from "./components/Skills";
import Contact from "./components/Contact";
import Projects from "./components/Projects";

const { Content } = Layout;
ReactGA.initialize(Keys.GOOGLE_TRACKING_ID); //Unique Google Analytics tracking number

function fireTracking() {
  ReactGA.pageview(window.location.hash);
}

class App extends Component {
  render() {
    return (
      <Router onUpdate={fireTracking} history={createHistory({ basename: process.env.PUBLIC_URL })}>
        <div>
          <Layout>
            <HeaderList />
            <Content className="Content">
              <div className="RouteContent">
                <Switch>
                  <Route exact path="/" component={AboutMe} />
                  <Route path="/skills" component={Skills} />
                  <Route path="/projects" component={Projects} />
                  <Route path="/Contact" component={Contact} />
                </Switch>
              </div>
            </Content>
          </Layout>
        </div>
      </Router>
    );
  }
}

export default App;

推荐答案

反应v16.8或更高版本

浏览量可以通过 useEffect 函数生成； withRouter 用于在路线更改时注入道具：

React v16.8 or higher

The pageviews can be generated in a useEffect function; withRouter is used to inject props on route changes:

import React, { useEffect }          from 'react';
import { Switch, Route, withRouter } from 'react-router-dom';
import ReactGA                       from 'react-ga';
import Keys                          from './config/keys';

//Unique Google Analytics tracking number
ReactGA.initialize(Keys.GOOGLE_TRACKING_ID); 

const App = () => {

    useEffect( () => {

        // This line will trigger on a route change
        ReactGA.pageview(window.location.pathname + window.location.search); 

    });

    return (/* Code here */);

}

export default withRouter(App);

React v16.8之前的版本

您需要在componentDidMount和componentDidUpdate中生成综合浏览量：

Prior to React v16.8

You need to generate a pageview in componentDidMount and componentDidUpdate:

componentDidMount  = () => ReactGA.pageview(window.location.pathname + window.location.search);
componentDidUpdate = () => ReactGA.pageview(window.location.pathname + window.location.search);

因此，最终代码：

import React, { Component } from "react";
import HeaderList from "./components/Header";
import "./App.css";
import { Layout } from "antd";
import { Router, Route, Switch } from "react-router-dom";
import createHistory from "history/createBrowserHistory";
import ReactGA from 'react-ga';
import Keys from './config/keys';

import AboutMe from "./components/AboutMe";
import Skills from "./components/Skills";
import Contact from "./components/Contact";
import Projects from "./components/Projects";

const { Content } = Layout;
ReactGA.initialize(Keys.GOOGLE_TRACKING_ID); //Unique Google Analytics tracking number

class App extends Component {

  componentDidMount  = () => ReactGA.pageview(window.location.pathname + window.location.search);
  componentDidUpdate = () => ReactGA.pageview(window.location.pathname + window.location.search);

  render() {
    return (
      <Router>
        <div>
          <Layout>
            <HeaderList />
            <Content className="Content">
              <div className="RouteContent">
                <Switch>
                  <Route exact path="/" component={AboutMe} />
                  <Route path="/skills" component={Skills} />
                  <Route path="/projects" component={Projects} />
                  <Route path="/Contact" component={Contact} />
                </Switch>
              </div>
            </Content>
          </Layout>
        </div>
      </Router>
    );
  }
}

export default App;
