如何使用下面的HTTP请求从服务器获取数据 [英] How to use below HTTP request to get data from server

问题描述

我对angular并不陌生，因为我得到了HTTP get service url以从服务器获取数据如何订阅并获取数据.

I am new to angular I was given HTTP get service url to get the data from server How can I subscribe it and get the data.

/dashboard/graphics-chart/v1/{roleId}.

下面是我在服务文件中编写的方法

below is the method i have written in service file

  getgraphdata(defaultroleID): Observable<any> {
    return this.apiService.get(WebServiceUrl.dashboard.getPiechartData + '/' + defaultroleID)
      .pipe(map(data => data));
  }

如何将其订阅到TS文件中.

How can I subscibe it in TS file.

推荐答案

在组件构造函数中定义服务，并按如下所示调用servis方法:

Define your service in component constructor and call your servis method as following:

this.yourServiceName.getgraphdata(this.defaultroleID).subscribe(res=>{
   console.log(res)
});
