我将使用angular 4向django后端api提交表单，但是当我单击“保存”按钮时没有任何动作发生。我监视后端，没有任何传入的请求我无法弄清楚我的代码出错的地方，遵循我的代码：
addEmployee.component.ts：
import { Employee } from './../employee';
import { AddEmployeeService } from './add-employee.service';
import { Component, OnInit } from '@angular/core';
import { DataService } from './../../services/data.service';
@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(
data => this.jobs = data
);
}
onSave(){
this.dataService.saveEmployee(this.employee);
}
}
Employee.ts：
export class Employee
{
constructor

public id: number,
