DESCRIPTION ^

This is an action role that lets your Catalyst::Action match on standard HTTP methods, such as GET, POST, etc.

Since most web browsers have limited support for rich HTTP Method vocabularies we use Plack::Middleware::MethodOverride which allows you to 'tunnel' your request method over POST This works in two ways. You can set an extension HTTP header X-HTTP-Method-Override which will contain the value of the desired request method, or you may set a search query parameter x-tunneled-method. Remember, these only work over HTTP Request type POST. See Plack::Middleware::MethodOverride for more.

REQUIRES ^

This role requires the following methods in the consuming class.

match

match_captures

Returns 1 if the action matches the existing request and zero if not.

METHODS ^

This role defines the following methods

match

match_captures

Around method modifier that return 1 if the request method matches one of the allowed methods (see "http_methods") and zero otherwise.

allowed_http_methods

An array of strings that are the allowed http methods for matching this action normalized as noted above (using X-Method* overrides).

list_extra_info

Adds a key => [@values] "HTTP_METHODS" whose value is an ArrayRef of sorted allowed methods to the ->list_extra_info HashRef. This is used primarily for debugging output.

_has_expected_http_method ($expected)

Private method which returns 1 if $expected matches one of the allowed in "http_methods" and zero otherwise.
