Module: Roda::RodaPlugins::HeaderMatchers

Overview

The header_matchers plugin adds hash matchers for matching on less-common HTTP headers.

plugin :header_matchers

It adds a :header matcher for matching on arbitrary headers, which matches if the header is present:

r.on :header=>'X-App-Token' do |header_value|
end

It adds a :host matcher for matching by the host of the request:

r.on :host=>'foo.example.com' do
end
r.on :host=>/\A\w+.example.com/ do
end

It adds a :user_agent matcher for matching on a user agent patterns, which yields the regexp captures to the block:

r.on :user_agent=>/Chrome\/([.\d]+)/ do |chrome_version|
end

It adds an :accept matcher for matching based on the Accept header:

r.on :accept=>'text/csv' do
end

Note that the accept matcher is very simple and cannot handle wildcards, priorities, or anything but a simple comma separated list of mime types.
