尝试在单击按钮时在Angular中附加一个REST url。

<button (click)="sendRequest()">发送请求</button>

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

export class YourComponent {
  constructor(private http: HttpClient) {}

  sendRequest() {
    const baseUrl = 'https://api.example.com'; // REST API的基础URL
    const endpoint = '/users'; // REST API的端点

    const url = `${baseUrl}${endpoint}`; // 构建完整的REST URL

    // 发送HTTP请求
    this.http.get(url).subscribe(response => {
      // 处理响应数据
      console.log(response);
    });
  }
}

const params = new URLSearchParams();
params.set('param1', 'value1');
params.set('param2', 'value2');

const urlWithParams = `${url}?${params.toString()}`;

const userId = '123';
const urlWithParams = `${baseUrl}/users/${userId}`;
