Http::Exceptions

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 SocketError or 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 Http::Exceptions::HttpException.

Installation

Add this line to your application's Gemfile:

gem 'http-exceptions'

And then execute:

$ bundle

Or install it yourself as:

$ gem install http-exceptions

Usage

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 2XX.

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

Support

Currently, this only has been tested with HTTParty. It should however work with any library that delegates to the ruby http library.
