Optional trailing slash in regex

https://embed.thatsite.com?id=
https://embed.thatsite.com/?id=

Im trying to get the trailing slash as optional before ?id=

I tried 

https?:\/\/embed\.([^\/]*)\.com\/\?id=([0-9]+) //works with slash only
https:\/\/embed\.([^\/]*)\.com\?id=([0-9]+) //works without slash

So, trailing slash should be optional before ?id= because embed.thatsite.com changes with both url types.Is there any way to make it working.Thankyou

Solution

  • You can make your / as optional using ?

    https?:\/\/embed\.([^\/]*)\.com\/?\?id=([0-9]+)

    https?:\/\/embed\. match http\\embed. or https\\embed. where s is optional ?

    ([^\/]*) match everything except /

    \.com\/?\? match .com and optional / and ? character

    id=([0-9]+) match id= and capture numeric values as many as possible
