Question

我在nodeJs中写了我的Api。我从Api获得了数据但是在[[object Object]，[object Object]]这个格式中。当我将这个数组设置为我的数组变量时，它给出了空数组。请帮我如何将这个数组分配到我定义的数组变量？

我的员工服务

import { Injectable } from '@angular/core';
import { Http, Response } from '@angular/http';
import 'rxjs/Rx';
@Injectable()
export class EmployeeService {
private baseUrl = 'http://localhost:5000/Role';
constructor(private _http: Http) { }
getRoleData() {
    const url = 'http://localhost:5000/Role';
    return this._http.get(url)
        .map(x => x.json());
}

EmployeeComponent.ts

import { Component, OnInit, ViewChild } from '@angular/core';
import { Response } from '@angular/http';
import { Employee, EmployeeService } from './employee-service';
import { Role } from '../../Modules/Role.module';
@Component({
       selector: 'app-employee-master',
       templateUrl: './employee-master.component.html',
       styleUrls: ['./employee-master.component.scss'],
       providers: [EmployeeService]
})
export class EmployeeMasterComponent implements OnInit {
 roles: Role[] = [];
constructor(private employeeService: EmployeeService) {}
 ngOnInit() {
  this.employeeService.getRoleData().subscribe(x => this.roles = x);
  console.log("Role" + this.roles);
}

}

角色模块

export class Role {
public OID: number;
public RollNo: string;
public RollName: string;
public GCRecord: string;
public OptimisticLockField: string;

constructor(OID: number, RollNo: string, RollName: string, GCRecord: string, OptimisticLockField:string) {
    this.OID = OID;
    this.RollNo = RollNo;
    this.RollName = RollName;
    this.GCRecord = GCRecord;
    this.OptimisticLockField = OptimisticLockField;
}
}

我的api回复

[
  {
     "GCRecord": null,"OID": 1,"RollNo": "1","RollName": 
     "HR","OptimisticLockField": null
   },
  {
     "GCRecord": null,
     "OID": 2,
      "RollNo": "2",
      "RollName": "Admin",
      "OptimisticLockField": null
   }]
