如何消費服務數據* ngFor

Question

在這裏，我訪問HTTP服務創建一個簡單的服務，請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綁定此服務的信息

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

    }

您需要從服務中返回數據並將其綁定到組件內部，

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