reactjs - React 应用程序上的 Google Analytics(分析)不起作用

Question

我在 github 页面上托管了我的作品集(仍在开发中)。它只是一个具有静态内容的网络应用程序。我需要将 Google Analytics 添加到我的投资组合中并获取访问次数(主要是为了熟悉流程)。我发现react-ga可用于在 React Apps(使用 create-react-app 创建)上配置 Google Analytics 的模块。

并关注 this教程并对其进行配置和托管。我用 检查了网站测试流量但谷歌分析仪表板没有更新。可能是什么情况？它应该按照教程工作。由于我是 Google Analytics 的新手，我很难弄清楚这个问题。

这是我的应用.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;

React v16.8 或更高版本

可以在 useEffect 中生成综合浏览量功能; withRouter用于在路由更改时注入(inject) Prop :

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);

在 React v16.8 之前

你需要在componentDidMount和componentDidUpdate中生成一个pageview:

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

所以，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;
