如何消费服务数据* ngFor

Question

在这里，我访问HTTP服务创建一个简单的服务，请helpme我如何能在* ngFor

import { Component } from '@angular/core'; 
    import {Http } from '@angular/http'; 
import { Injectable } from '@angular/core'; 
    @Injectable() 
    export class EmployeeService { 
     constructor(private http: Http) { } 
    GetStudentData() { 

     this.http.get('api/Employee').subscribe(response => { 

      this.student = response.json(); 
       }) 
    } 
    } 

Student.component.ts绑定此服务的信息

GetStudentData() { 
     var studentser = this.EmpServ.GetStudentData(); 
        //Here How can i Bind 

    }

Answer 1

您需要从服务中返回数据并将其绑定到组件内部，

GetStudentData() { 
     this.http.get('api/Employee').subscribe(response => { 
     this.student = response.json(); 
     }) 
    return this.student; 
}
