javascript - javascript中的正则表达式从url中删除数字路径

Question

我有如下所示的带有客户 ID 等的 URL。我想删除它们并用星号代替它们。下面的例子会给你一个更好的想法。

/paas/service/3.0/part/d878bc1e-9bb8-4a0e/log/account/7367c100-9390-11e3/resource/AdminHistory --> /paas/service/3.0/part/*/log/account/*/resource/AdminHistory

/hs/service/3.0/bootstrap/mnd/3388959354 --> /hs/service/3.0/bootstrap/mnd/*

/paas/service/3.0/part/d878bc1e-9bb8-4a0e-b224-a4ba0d7dfcec/asset --> /paas/service/3.0/part/*/asset

/paas/service/3.0/part/3c5631df-52c9/servicepolicy/8ee6ba08-8d7a/carrierPlan/c2b4a364-98e3-4546 --> /paas/service/3.0/part/*/servicepolicy/*/carrierPlan/*

ID 可以是数字或字母数字。我应该如何处理这个问题？

Answer 1

The IDs are either numeric or alphanumeric.

示例网址中的所有部分都包含字母或数字，因此您需要知道 ID 之前的文本是什么，以便您可以定位该加号后面的 ID。

也许是这样的:

function modifyURL(url) {
  return url.replace(/(\/(?:part|account|mnd|servicepolicy|carrierPlan)\/)[^\/]+/g, "$1*");
}

console.log(modifyURL("/paas/service/3.0/part/d878bc1e-9bb8-4a0e/log/account/7367c100-9390-11e3/resource/AdminHistory"));
console.log(modifyURL("/hs/service/3.0/bootstrap/mnd/3388959354"));
console.log(modifyURL("/paas/service/3.0/part/d878bc1e-9bb8-4a0e-b224-a4ba0d7dfcec/asset"));
console.log(modifyURL("/paas/service/3.0/part/3c5631df-52c9/servicepolicy/8ee6ba08-8d7a/carrierPlan/c2b4a364-98e3-4546"));

解释我使用的正则表达式:

(       // start of capturing submatch         
\/      // match a forward slash
(?:     // start of non-capturing group       
part|account|mnd|servicepolicy|carrierPlan   // match one of those words
)       // end of non-capturing group
\/      // match forward slash
)       // end of capturing submatch
[^\/]+  // match one or more of anything but a forward slash
