如何使用JavaScript正则表达式从URL中提取斜杠之间的值？

let pattern = "{note}/:pakid:/corrinsdetail/{corrinsaleid}/{corrinspakid}/{corrinsinsta}/{corrinsvernr}/{verfrom}/{verto}/{name}/:tab:";
let url = "0001668882/41/corrinsdetail/0001023444/41/0020751259/0005/756/756/sap_basis/validitydetails";

function extractinfo(pattern, url) {
  const urlregex = new regexp(pattern.replace(/({|:)[w-]+(}|:)/g, "[\w-]+").replace(///g, "/"));
  if (!urlregex.test(url)) {
    throw new error("输入的url不符合pattern");
  }
  let keys = pattern.split("/");
  let values = url.replace(/(?|#).*/, "").split("/");
  let result = {};
  keys.foreach((v, i) => {
    if (/({|:)w+(}|:)/.test(v)) {
      result[v.replace(/({|:|})/g, "")] = values[i];
    }
  });
  return result;
}

console.log(extractinfo(pattern, url));

{
  note: "0001668882",
  pakid: "41",
  corrInsAleid: "0001023444",
  corrInsPakId: "41",
  corrInsInsta: "0020751259",
  corrInsVernr: "0005",
  verFrom: "756",
  verTo: "756",
  name: "SAP_BASIS",
  tab: "ValidityDetails"
}
