如何在angular 4中创建用于post我的表单的json数组

npm install @angular/common --save

import { HttpClient, HttpHeaders } from '@angular/common/http';

constructor(private http: HttpClient) { }

postData(formData: any[]) {
  const url = 'https://example.com/api/endpoint'; // 替换为您的API端点URL
  const headers = new HttpHeaders().set('Content-Type', 'application/json');
  const body = JSON.stringify(formData);

  return this.http.post(url, body, { headers }).toPromise();
}

submitForm() {
  const formData = [
    { name: 'John', age: 25 },
    { name: 'Jane', age: 30 }
  ]; // 替换为您的表单数据

  this.postData(formData)
    .then(response => {
      console.log('POST请求成功', response);
      // 处理成功响应
    })
    .catch(error => {
      console.error('POST请求失败', error);
      // 处理错误
    });
}
