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
      string: ""
    headers: {}
  response:
    status:
      code: 200
      message: OK
    headers:
      Content-Length:
      - "5"
    body:
      encoding: UTF-8
      string: Hello
    http_version: "1.1"

Scenarios
the VCR query parser gets its value from `query_parser`
Given
a file named "query_parser.rb" with: 
require 'vcr'
require 'rack'

VCR.configure do |c|
  c.query_parser = lambda { |query| raise query.inspect }
  c.default_cassette_options = {:match_requests_on => [:query]}
  c.hook_into :webmock
  c.cassette_library_dir = 'cassettes'
end

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"
the `query_parser` defaults to the standard library's `CGI.parse`
Given
a file named "query_parser_default.rb" with: 
require 'vcr'

VCR.configure do |c|
  c.hook_into :webmock
  c.default_cassette_options = {:match_requests_on => [:query]}
  c.cassette_library_dir = 'cassettes'
end

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_default.rb
Then
it should pass with "Hello"
