如何仅使用正则表达式从URL中提取参数值

function extractParamsFromURL(url) {
  const regex = /\?(.*)$/;
  const match = regex.exec(url);
  if (match) {
    const paramsString = match[1];
    const paramsRegex = /([^&=]+)=([^&]*)/g;
    const params = {};
    let paramMatch;
    while ((paramMatch = paramsRegex.exec(paramsString)) !== null) {
      const paramName = decodeURIComponent(paramMatch[1]);
      const paramValue = decodeURIComponent(paramMatch[2]);
      params[paramName] = paramValue;
    }
    return params;
  }
  return {};
}

const url = "https://www.example.com/path?param1=value1&param2=value2";
const params = extractParamsFromURL(url);
console.log(params);

{
  param1: "value1",
  param2: "value2"
}
