我要使用角度4提交表單到django後端api，但當單擊保存按鈕時沒有任何動作發生。我監控的後端並沒有任何傳入請求我無法揣摩出我的代碼出錯，下面我的代碼：發送POST請求 - angular4
addEmployee.component.ts：
import { Employee } from './../employee';

@Component({
selector: 'app-addemployee',
templateUrl: './addemployee.component.html',
styleUrls: ['./addemployee.component.css']
})
export class AddemployeeComponent implements OnInit {
jobs: Array<any>;
mahalyas: Array<any>;
courses: Array<any>;
employee: Array<any>;
constructor(private dataService: DataService, private AddEmployeeService: AddEmployeeService) { }
ngOnInit() {
this.dataService.getAllMahaleyahs().subscribe(
data => this.mahalyas = data
);
this.dataService.getAllCourses().subscribe(
data => this.courses = data

this.dataService.getAllJobs().subscribe(
