删除URL指定参数和添加URL参数的方法

1.删除url指定参数

const urlParams = new URLSearchParams(window.location.search);
urlParams.delete('token'); //删除url上面的token参数
window.location.search = urlParams.toString();

2.添加url参数

let url = new URL('https://urlExample.com?aaa=1');
let urlParams = new URLSearchParams(url.search);
Params.append('key2', 'value2');
url.search=urlParams.toString();
let newUrl=url.href(); // https://urlExample.com?aaa=1&key2=value2
