Feature: query_parser
By default, VCR will parse query strings using `CGI.parse` from the Ruby
standard library. This may not be the most optimal or performant library
available. You can set the `query_parser` configuration option to use a
different parser (such as `Rack::Utils.method(:parse_query)`) to decode,
normalize, and/or provide a comparison object for query strings.
The configured query parser needs to expose a `.call` method that returns an
object which is comparable. This instance needs to implement the following
API:
* `#==` => boolean
Background:
Given a file named "cassettes/example.yml" with:
"""

http_interactions:
- request:
method: get
uri: http://url.example.com/?bravo=2&alpha=1
body:
encoding: UTF-8

"""
Scenario: the VCR query parser gets its value from `query_parser`
Given a file named "query_parser.rb" with:
"""ruby
require 'vcr'
require 'rack'
VCR.configure do |c|
c.query_parser = lambda { |query| raise query.inspect }
c.default_cassette_options = {:match_requests_on => [:query]}

uri = URI.parse('http://other-url.example.com/?bravo=2&alpha=1')
VCR.use_cassette('example') do
puts Net::HTTP.get_response(uri).body
end
"""
When I run `ruby query_parser.rb`
Then it should fail with an error like:
"""
"alpha=1&bravo=2"
"""
Scenario: the `query_parser` defaults to the standard library's `CGI.parse`
Given a file named "query_parser_default.rb" with:
