URI Parser

By default, VCR will parse URIs using URI from the Ruby standard library. There are some URIs seen out in the wild that URI cannot parse properly. You can set the uri_parser configuration option to use a different parser (such as Addressable::URI) to work with these URIs.

The configured URI parser needs to expose a .parse class method that returns an instance of the uri. This uri instance needs to implement the following API:

• #scheme => a string

• #host => a string

• #port => a fixnum

• #path => a string

• #query => a string

• #to_s => a string

• #port=

• #query=

• #== => boolean

Given a file named "cassettes/example.yml" with:

---
http_interactions:
- request:
    method: get
    uri: http://example.com/hello
    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"

the VCR uri parser gets its value from uri_parser

Given a file named "uri_parser.rb" with:

require 'vcr'
require 'uri'

module MyURI
  def self.parse(url)
    uri = URI.parse(url)
    uri.host = 'example.com'
    uri.path = '/hello'
    uri
  end
end

VCR.configure do |c|
  c.uri_parser = MyURI
  c.hook_into :webmock
  c.cassette_library_dir = 'cassettes'
end

VCR.use_cassette('example') do
  puts Net::HTTP.get_response('evil.org', '/projects').body
end

When I run ruby uri_parser.rb

Then it should pass with "Hello".

the uri_parser defaults to the standard library's URI

Given a file named "uri_parser_default.rb" with:

require 'vcr'

VCR.configure do |c|
  c.hook_into :webmock
  c.cassette_library_dir = 'cassettes'
end

VCR.use_cassette('example') do
  puts Net::HTTP.get_response('example.com', '/hello').body
end

When I run ruby uri_parser_default.rb

Then it should pass with "Hello".
