生成服务getallemployee时出错

problem
get error when make service getallemployee

在getemployeelist函数上完成错误

如何解决这个问题呢？



我尝试过：

error done on getemployeelist function
how to solve this problem please?

What I have tried:

export class Employee {
    EmployeeId : number;
    BranchCode:number;
    EmployeeName:string;
    EmployeeAge:number;
    JoinDate:Date;
    BirthDate:Date;
    Active : boolean;
}

import { Injectable } from '@angular/core'
import { HttpClient } from '@angular/common/http'
import {Employee} from'./employee.model'
import { Observable } from 'rxjs'
import 'rxjs/add/operator/map'
import 'rxjs/add/operator/toPromise'
import 'rxjs/add/observable/fromPromise'
import { map } from 'rxjs/operators'

@Injectable()
export class ApiService{
    employeeList : Employee[];
    constructor(private http : HttpClient){}

       
   
        
        getEmployeeList(): Observable<Employee[]> {
          return this.http
              .get('https://localhost:44326/api/Employee')
              .map((response: Response) => {
                  return <Employee[]>response.json();
              })
              .catch(this.handleError);
      }

}

推荐答案

this.http
.get('https://localhost:44326/api/Employee')
.then(res => //your logic)
