如果需要传递参数给GET请求,可以使用HttpParams类。以下是一个示例: 代码语言:txt 复制 import { HttpClient, HttpParams } from '@angular/common/http'; getData() { let params = new HttpParams().set('param1', 'value1').set('param2', 'value2'); this.http.get('https://api.example.com/dat...
导入HTTPClient模块使用以下代码: import { HttpClient } from '@angular/common/http'; 然后,你可以在你的组件或服务中创建HTTPClient实例,并使用它发送GET、POST、PUT等HTTP请求。例如,你可以发送GET请求来获取数据: constructor(private http: HttpClient) { } getData() { return this.http.get('https://api....
