Matching on Query String
Use the :query
request matcher to match requests on the query string portion of the request URI.
You can use this (alone, or in combination with others) as an alternative to :uri
so that non-deterministic portions of the URI are not considered as part of the request matching.
Background ()
Given a previously recorded cassette file "cassettes/example.yml" with:
---
http_interactions:
- request:
method: post
uri: http://host1.com/query?date=2011-09-01
body:
encoding: UTF-8
string: ""
headers: {}
response:
status:
code: 200
message: OK
headers:
Content-Length:
- "19"
body:
encoding: UTF-8
string: 2011-09-01 response
http_version: "1.1"

Replay interaction that matches the query string
And a file named "query_matching.rb" with:
include_http_adapter_for("<http_lib>")
require 'vcr'
VCR.configure do |c|
<configuration>
c.default_cassette_options = { :match_requests_on => [:query] }
c.cassette_library_dir = 'cassettes'
end
VCR.use_cassette('example', :match_requests_on => [:query]) do
puts "Response for 2011-09-01 /query: " + response_body_for(:get, "http://example.com/query?date=2011-09-01")
end
VCR.use_cassette('example', :match_requests_on => [:query]) do
puts "Response for 2011-09-02 /query: " + response_body_for(:get, "http://example.com/query?date=2011-09-02")
end
When I run ruby query_matching.rb
Then it should pass with:
Response for 2011-09-01 /query: 2011-09-01 response
Response for 2011-09-02 /query: 2011-09-02 response
