Matching on Body as JSON

Use the :body_as_json request matcher to match requests on the request body where the body is JSON.

Background ()

Given a previously recorded cassette file "cassettes/example.yml" with:

---
http_interactions:
- request:
    method: post
    uri: http://example.net/some/long/path
    body:
      encoding: UTF-8
      string: '{ "a" : "1" }'
    headers: {}
  response:
    status:
      code: 200
      message: OK
    headers:
      Content-Length:
      - "14"
    body:
      encoding: UTF-8
      string: body1 response
    http_version: "1.1"

Replay interaction that matches the body as JSON

And a file named "body_as_json_matching.rb" with:

include_http_adapter_for("<http_lib>")

require 'vcr'

VCR.configure do |c|
  <configuration>
  c.cassette_library_dir = 'cassettes'
end

VCR.use_cassette('example', :match_requests_on => [:body_as_json]) do
  puts "Response for body as json 2: " + response_body_for(:put, "http://example.com/", '{ "a" : "1", "b" : "2" }')
end

VCR.use_cassette('example', :match_requests_on => [:body_as_json]) do
  puts "Response for body as json 1: " + response_body_for(:put, "http://example.com/", '{ "a" : "1" }')
end

When I run ruby body_as_json_matching.rb

Then it should pass with:

Response for body as json 2: body2 response
Response for body as json 1: body1 response
