How to use webmock regex matcher?

Question

How to match a URL like:

http://www.example.com/foo/:id/bar
http://www.example.com/foo/1/bar
http://www.example.com/foo/999/bar

stub_request(:post, "www.example.com")

Are you looking for a Regexp to match the URL patterns? – user2398029 Dec 08 '12 at 03:12 — user2398029, Dec 08 '12 at 03:12

You can use %r{} instead of // for your regular expression in Ruby to avoid having to escape the forward slashes in URLs. For example:

stub_request(:post, %r{\Ahttp://www.example.com/foo/\d+/bar\z})

Also, can use many other characters instead of `{}` to close the regex, for example `%r()` or `%r''` This is helpful because the regex quantity modifier uses curly braces. So if you're trying to match a URL or something with a specific number of characters, like a 36 character API key, use something like parentheses to close the regex. – johnpitchko Jun 12 '21 at 16:40

The second argument to stub_request must be a regular expression, not a string.

stub_request(:post, /http:\/\/www.example.com\/foo\/\d+\/bar/)

http://www\..*?\.com/foo/\d+/bar should work for you.

@BSeven `\.` is escaping the `.` dot character while `.*?` means any character (the dot character means any character) zero or more times (the `*` is zero or more times while `+` is 1 or more times) and make it non-greedy (the question mark `?`) so it stops looking as soon as it hits `.com`. – Jack Dec 11 '12 at 00:02
