跟踪Angular2中的Google Analytics网页浏览量

标签: javascript google-analytics angular

我使用Angular 2作为前端构建了一个新站点。由于一切都是通过推送状态完成的,因此没有页面加载通常会触发Google Analytics代码将页面视图发送到Google的服务器。

如何手动向Google发送网页浏览事件,以便跟踪我网站的哪些用户正在查看?

我设法通过订阅路由器上的更改,检查路由实际已更改(我有时在某些路由上获得多个事件)然后将新路径发送给Google来设置此工作。

<强> app.component.ts

import { ... } from '...';

// Declare ga function as ambient
declare var ga:Function;

@Component({ ... })

export class AppComponent {
    private currentRoute:string;

    constructor(_router:Router) {
        // Using Rx's built in `distinctUntilChanged ` feature to handle url change c/o @dloomb's answer
        router.events.distinctUntilChanged((previous: any, current: any) => {
            // Subscribe to any `NavigationEnd` events where the url has changed
            if(current instanceof NavigationEnd) {
                return previous.url === current.url;
            }
            return true;
        }).subscribe((x: any) => {
            ga('set', 'page', x.url);
            ga('send', 'pageview')
        });
      }
    }
}

在加载angular2应用之前,您还需要在主索引文件中包含Google Analytics代码,以便存在全局ga对象,但您不希望两次发送初始视图。为此,请从GA脚本中删除以下行

<强>的index.html

<script>
  (function(i,s,o,g,r,a,m){...})(window,document,'script','https://www.google-analytics.com/analytics.js','ga');

  ga('create', 'UA-XXXXXXXX-X', 'auto');
  // Remove this line to avoid sending the first page view twice.
  //ga('send', 'pageview');

</script>
<!-- 
    Load your ng2 app after ga. 
    This style of deferred script loading doesn't guarantee this will happen
    but you can use Promise's or what works for your particular project. 
-->
<script defer type="text/javascript" src="/app.js"></script>

使用第三方库

作为自己实施GA的替代方案,库Angulartics2也是实施GA跟踪的流行工具,也可以与其他分析供应商集成。

扩展伊恩的答案。您可以使用Rx的内置功能来处理当前路由和新路由之间的区别。

import { NavigationEnd, Router } from '@angular/router';

declare var ga: any;

export class AppComponent {
        constructor(public router: Router) {
            router.events.distinctUntilChanged((previous: any, current: any) => {
                if(current instanceof NavigationEnd) {
                    return previous.url === current.url;
                }
                return true;
            }).subscribe((x: any) => {
                console.log('router.change', x);
                ga('send', 'pageview', x.url);
            });
        }
    }

我们使用distinctUntilChanged运算符使观察者只发出NavigationEnd类型的项目,并且没有与先前发出的项目相同的路由。

如果您在2017年8月之后遇到此问题 ,那么您很可能应该使用gtag.js(Google Universal Analytics全球网站代码)而不是旧analytics.js。我建议您在继续之前检查Migrate from analytics.js to gtag.js页面和How gtag.js works in Single page applications之间的差异。

当您从Google Analytics获取代码段时,它看起来像这样:

<!-- Global site tag (gtag.js) - Google Analytics -->
<script async src="https://www.googletagmanager.com/gtag/js?id=<%= GOOGLE_ANALYTICS_ID %>"></script>
<script>
  window.dataLayer = window.dataLayer || [];
  function gtag(){dataLayer.push(arguments);}
  gtag('js', new Date());

  gtag('config', '<%= GOOGLE_ANALYTICS_ID %>'); <!-- Remove that one -->
</script>

您需要删除脚本的最后一行,然后将其余部分添加到index.html

然后,您必须将从上面脚本中删除的行添加到代码中,并将该页面添加到跟踪。基本上它与上面为analytics.js建议的人几乎相同,但现在你使用gtag.js函数。

例如,如果您想跟踪您在此处打开的所有页面,请参阅示例代码:

import { Component, OnInit } from '@angular/core';
import { Router, NavigationEnd } from '@angular/router';
import 'rxjs/add/operator/distinctUntilChanged';

// This still has to be declared
declare var gtag: Function;

@Component({
    moduleId: module.id,
    selector: 'my-app',
    templateUrl: 'app.component.html',
    styleUrls: ['app.component.css'],
})
export class AppComponent implements OnInit {

    constructor(private router: Router) { }

    ngOnInit() {
        this.router.events.distinctUntilChanged((previous: any, current: any) => {
            // Subscribe to any `NavigationEnd` events where the url has changed
            if(current instanceof NavigationEnd) {
                return previous.url === current.url;
            }
            return true;
        }).subscribe((x: any) => {
            gtag('config', '<%= GOOGLE_ANALYTICS_ID %>', {'page_path': x.url});
        });
    }
}

如果您已阅读gtag.js的文档,那么您就会知道可能有大量的跟踪选项,但我会专注于此处的最基本用法。

在Angular 6中,我建议使用app.component.ts:

import { Component, OnInit } from '@angular/core';
import { Router, NavigationEnd } from '@angular/router'
import { Title } from '@angular/platform-browser';

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})

export class AppComponent {

  constructor(
    private router: Router,
    private titleService: Title
  ){ }

  ngOnInit() {
     this.router.events.subscribe(event => {
      if (event instanceof NavigationEnd) {
        (<any>window).gtag('config', '<%= GOOGLE_ANALYTICS_ID %>', {
          'page_title' : this.titleService.getTitle(),
          'page_path': event.urlAfterRedirects
        });
      }
    });
  }

}

对于index.html:

  <!-- Global site tag (gtag.js) - Google Analytics -->
  <script async src="https://www.googletagmanager.com/gtag/js?id=<%= GOOGLE_ANALYTICS_ID %>"></script>
  <script>
    window.dataLayer = window.dataLayer || [];
    function gtag() { dataLayer.push(arguments); }
    gtag('js', new Date());
  </script>

您可以使用Angular提供的“标题”服务来管理页面的标题:https://angular.io/guide/set-document-title

答案 4 :(得分:0)

假设每个Angular Route在app.routing.ts中都有自己的标题:

   {
    path: 'shop',
    component: ShopComponent,
    data: {
      title: ' == This is Shop Component Title =='
    },
    canActivate: [AuthGuard]
  },

前面提到的解决方案仍将在Google Analytics(分析)报告中为每条路线显示相同的页面标题。为了利用相应的Angular Route标题(而不是始终使用index.html <title>标签内容),请使用以下app.component.ts

中的代码
  this.router.events.subscribe(event => {

  if (event instanceof NavigationEnd) {
    (<any>window).ga('set', 'page', event.urlAfterRedirects);

    // ----------
    //use the following 3 lines of code to use
    //correnct titles for routes        
    // ----------

    let currentRoute = this.route.root;
    let title = this.getPageTitle(currentRoute);
    (<any>window).ga('set', 'title', title);

    (<any>window).ga('send', 'pageview');

  }
});

...其中getPageTitle方法如下:

getPageTitle = function (currentRoute: ActivatedRoute) {
  let data;
    do {
      const childrenRoutes = currentRoute.children;
      currentRoute = null;
      childrenRoutes.forEach(route => {

      if (route.outlet === 'primary') {
        currentRoute = route;
        data = route.snapshot.data;
      }
    });
  } while (currentRoute);
  return data.title;
};

注意:此解决方案适用于Anguler 5及以下版本。在Angular 6中,您还可以使用TitleService

this.router.events.subscribe(event => {
    if (event instanceof NavigationEnd) {
        ga('set','page', event.urlAfterRedirects);
        ga('send', 'pageview');
    }
});
