如何在具有固定参数和可变形式输入的angular中发送post请求

npm install @angular/common@latest @angular/compiler@latest @angular/core@latest @angular/forms@latest

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

constructor(private http: HttpClient) { }

sendPostRequest(formData: any) {
  const url = 'https://example.com/api/post';
  const param1 = 'value1';
  const param2 = 'value2';

  const body = {
    param1: param1,
    param2: param2,
    ...formData // 可变形式输入
  };

  this.http.post(url, body).subscribe(
    response => {
      console.log('POST请求成功', response);
      // 处理响应数据
    },
    error => {
      console.error('POST请求失败', error);
      // 处理错误
    }
  );
}

<button (click)="sendPostRequest(formData)">发送POST请求</button>
