Http::Exceptions provides an easy way to rescue exceptions that might be thrown by your Http library. This was developed at Rainforest QA - you can read more in Introducing Http::Exceptions over on our blog.
If you're using a library such as the excellent HTTParty, you still have to deal with various types of exceptions. In an ideal world, the return code of the HTTP request would be the sole indicator of failures, but HTTP libraries can raise a large number of exceptions (such as
Net::ReadTimeout) that you need to handle.
Http::Exceptions converts any error that might be raised by your HTTP library and wrap it in a
Add this line to your application's Gemfile:
And then execute:
Or install it yourself as:
$ gem install http-exceptions
Only rescue raised exceptions.
response = Http::Exceptions.wrap_exception do HTTParty.get "http://www.google.com" end
Raise an exception if the return code of the API call is not
response = Http::Exceptions.wrap_and_check do HTTParty.get "http://www.google.com" end
You can then rescue the exception in the following way:
begin response = Http::Exceptions.wrap_and_check do HTTParty.get "http://www.google.com" end rescue Http::Exceptions::HttpException => e # ... end
Currently, this only has been tested with HTTParty. It should however work with any library that delegates to the ruby http library.
