for example, after a business is processed in the background, the backend forwards a url to the front-end route, and puts a parameter in the response headers in this url. So, how do you get this parameter? Does js have an idea? Thank you.

function urlParse(urlString){
// let url = decodeURIComponent(urlString);
let url = urlString;
let obj = {};
let reg = /[?&][^?&]+=[^?&]+/g;
let arr = url.match(reg);
if(arr){
arr.forEach((item)=>{
let tempArr = item.substring(1).split('=');
let key = decodeURIComponent(tempArr[0]);
let value = decodeURIComponent(tempArr[1]);
obj[key] = value;
})
}
return obj;
}the above function returns a json object;
4. Then print that object, and you can start playing
