# Matching on URI

Use the `:uri` request matcher to match requests on the request URI.

The `:uri` matcher is used (along with the `:method` matcher) by default if you do not specify how requests should match.

## Background ()

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

```
--- 
http_interactions: 
- request: 
    method: post
    uri: http://example.com/foo
    body: 
      encoding: UTF-8
      string: ""
    headers: {}
  response: 
    status: 
      code: 200
      message: OK
    headers: 
      Content-Length: 
      - "12"
    body: 
      encoding: UTF-8
      string: foo response
    http_version: "1.1"
  recorded_at: Tue, 01 Nov 2011 04:58:44 GMT
- request: 
    method: post
    uri: http://example.com/bar
    body: 
      encoding: UTF-8
      string: ""
    headers: {}
  response: 
    status: 
      code: 200
      message: OK
    headers: 
      Content-Length: 
      - "12"
    body: 
      encoding: UTF-8
      string: bar response
    http_version: "1.1"
  recorded_at: Tue, 01 Nov 2011 04:58:44 GMT
recorded_with: VCR 2.0.0
```

## Replay interaction that matches the request URI

*And* a file named "uri\_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 => [:uri]) do
  puts "Response for /bar: " + response_body_for(:get, "http://example.com/bar")
end

VCR.use_cassette('example', :match_requests_on => [:uri]) do
  puts "Response for /foo: " + response_body_for(:get,  "http://example.com/foo")
end
```

*When* I run `ruby uri_matching.rb`

*Then* it should pass with:

```
Response for /bar: bar response
Response for /foo: foo response
```
