如何在angular中使用URL编码的对象发出get请求？

import { URLSearchParams } from '@angular/http';

// 创建参数对象
const params = {
  key1: 'value1',
  key2: 'value2'
};

// URL编码对象
const searchParams = new URLSearchParams();
for (let key in params) {
  if (params.hasOwnProperty(key)) {
    searchParams.set(key, params[key]);
  }
}

// 将编码后的参数添加到URL
const url = 'https://example.com/api?' + searchParams.toString();

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

// 构建GET请求
this.http.get(url).subscribe(
  (data) => {
    // 请求成功的处理逻辑
  },
  (error) => {
    // 请求失败的处理逻辑
  }
);
