I use OpenURI library.
object = open("http://example.com")
If http://example.com server code response is equals to 200 my program acts as I expected.
But if http://example.com server response code is equals to 400 (or other) then script aborts with OpenURI::HTTPError: 404 Not Found.
I can avoid this if I use 'begin-rescue' construction and handle 'HTTPError exception'.
Is this a correct way?
Should I use Net/Http library instead of OpenURI to handle all cases?
Rescuing the OpenURI::HTTPError
is perfectly reasonable. See this related answer: https://stackoverflow.com/a/7495389/289274
But if you would rather not deal with exception handling, here's how you can do it with Net::HTTP
