js正则表达式提取url中斜杠之间的值
如何利用javascript正则表达式从url中提取斜杠（/）之间的值？
下面提供了一段代码，可以帮助你解决这一问题：
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;

- pattern：要匹配的正则表达式。
- url：要提取信息的url。
使用示例：
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";
console.log(extractinfo(pattern, url));输出结果：
{
note: "0001668882",
pakid: "41",
corrInsAleid: "0001023444",
corrInsPakId: "41",
corrInsInsta: "0020751259",
corrInsVernr: "0005",
verFrom: "756",
verTo: "756",
name: "SAP_BASIS",
tab: "ValidityDetails"
}
