如何用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";

// 清洗url
url = url.replace(/(?|#).*/, "");

// 模式替换
const urlregex = new regexp(pattern.replace(/({|:)[w-]+(}|:)/g, "[\w-]+").replace(///g, "/"));

// 检验url是否符合模式
if (!urlregex.test(url)) {
    throw new error("输入的url不符合pattern");
}

// 分割关键字和值
let keys = pattern.split("/");
let values = url.split("/");

let result = {};

// 匹配关键字和值
keys.foreach((v, i) => {
    if (/({|:)w+(}|:)/.test(v)) {
        result[v.replace(/({|:|})/g, "")] = values[i];
    }
});

console.log(result);

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