通过正则表达式替换 URL 中的多个斜线

Question

I am trying to create a regex in pcre, that is going to salinize URL with multiple slashes like the following:

https://www.domin.com/test1/////test2/somemoretests_67142 https://www.domin.com/test1/test2/somemoretests_67142///// https://www.domin.com/test1/test2///somemoretests_67142

So that I can replace it with the following: https://\2\4 and the link at the end of it looks: https://www.domin.com/test1/test2/somemoretests_67142

I have been struggling with it for the past couple of days, so any regex guru help is more than welcome:)

I have tried the following and more:

(http|https):\/\/(.*)(\/\/+)(.*) (http|https):\/\/(.*)(\/\/){2,}(.*) (http|https):\/\/(.*)(\/\/{2})(.*)

I am going to utilize these for Akamai to sanitize our URLs though cloudlet.

Answer 1

You can try:

(?<!https:\/)(?<!http:\/)(\/+$|(?<=\/)\/+)

And substitute the first group with empty string.
