Matching on Headers

Use the :headers request matcher to match requests on the request headers.

Replay interaction that matches the headers

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: ""
    headers: 
      X-User-Id: 
      - "1"
  response: 
    status: 
      code: 200
      message: OK
    headers: 
      Content-Length: 
      - "15"
    body: 
      encoding: UTF-8
      string: user 1 response
    http_version: "1.1"

- request: 
    method: post

    body:

      string: ""
    headers: 
      X-User-Id: 
      - "2"
  response: 
    status: 
      code: 200
      message: OK
    headers: 
      Content-Length:

    http_version: "1.1"

recorded_with: VCR 2.0.0

And a file named "header_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 => [:headers]) do
  puts "Response for user 2: " + response_body_for(:get, "http://example.com/", nil, 'X-User-Id' => '2')
end

VCR.use_cassette('example', :match_requests_on => [:headers]) do
  puts "Response for user 1: " + response_body_for(:get, "http://example.com/", nil, 'X-User-Id' => '1')
end

When I run ruby header_matching.rb

Then it should pass with:

Response for user 2: user 2 response
Response for user 1: user 1 response
