around_http_request hook

@exclude-18

The around_http_request hook wraps each HTTP request. It can be used
rather than separate before_http_request and after_http_request hooks
to simplify wrapping/transactional logic (such as using a VCR cassette).

In your block, call #proceed on the yielded request to cause it to continue.
Alternately, you can treat the request as a proc and pass it on to a method that
expects a block by prefixing it with an ampersand (&request).

Note that around_http_request will not work on Ruby 1.8. It uses a fiber
under the covers and thus is only available on interpreters that support fibers.
On 1.8, you can use separate before_http_request and after_http_request hooks.

Scenarios

globally handle requests using an around_http_request hook

Given

a file named "globally_handle_requests.rb" with:

include_http_adapter_for("http_lib")

request_count = 0
start_sinatra_app(:port => 7777) do
  get('/') { "Response #{request_count += 1 }" }
end

require 'vcr'

VCR.configure do |c|
  configuration
  c.cassette_library_dir = 'cassettes'
  c.around_http_request do |request|
    VCR.use_cassette('global', :record => :new_episodes, &request)
  end
end

puts "Response for request 1: " + response_body_for(:get, "http://localhost:7777/")
puts "Response for request 2: " + response_body_for(:get, "http://localhost:7777/")

When

I run ruby globally_handle_requests.rb

Then

it should pass with:

Response for request 1: Response 1
Response for request 2: Response 1

And

the file "cassettes/global.yml" should contain "body: Response 1"

Examples:
configuration	http_lib
c.hook_into :fakeweb	net/http
c.hook_into :webmock	net/http
c.hook_into :webmock	httpclient
c.hook_into :webmock	curb
c.hook_into :typhoeus	typhoeus
c.hook_into :excon	excon
c.hook_into :faraday	faraday (w/ net_http)
