如何使用Javascript读取get请求？

// 假设URL为：https://example.com?key1=value1&key2=value2
const urlParams = new URLSearchParams(window.location.search);
const key1 = urlParams.get('key1'); // 获取key1的值，即value1
const key2 = urlParams.get('key2'); // 获取key2的值，即value2

const url = window.location.href;
const regex = /[?&]([^=]+)=([^&#]*)/g;
const params = {};
let match;

while ((match = regex.exec(url))) {
  params[match[1]] = match[2];
}

const key1 = params['key1']; // 获取key1的值，即value1
const key2 = params['key2']; // 获取key2的值，即value2

const queryString = window.location.search;
const urlParams = new URLSearchParams(queryString);
const key1 = urlParams.get('key1'); // 获取key1的值，即value1
const key2 = urlParams.get('key2'); // 获取key2的值，即value2
