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? – Antiquity

Answer 1

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

Indelicate

@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. – Indelicate

Answer 2

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})

Gutter

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. – Horsey

Answer 3

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

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