Name

       Plack::Middleware::MethodOverride - Override REST methods to Plack apps via POST

Version

       version 0.20

Synopsis

       In your Plack app:

         use Plack::Builder;
         builder {
             enable MethodOverride;
             $app;
         };

       PUT via a query parameter in your POST forms:

         <form method="POST" action="/foo?x-tunneled-method=PUT">
           <!-- ... -->
         </form>

       Or override it via the "X-HTTP-Method-Override" header in a request:

         my $req = HTTP::Request->new(POST => '/foo', [
             'X-HTTP-Method-Override' => 'PUT'
         ]);

Description

       Writing REST <http://en.wikipedia.org/wiki/Representational_State_Transfer>ful apps is a
       good thing, but if you're also trying to support web browsers, it would be nice not to be
       reduced to "GET" and "POST" for everything.

       This middleware allows for "POST" requests that pretend to be something else: by adding
       either a header named "X-HTTP-Method-Override" to the request, or a query parameter named
       "x-tunneled-method" to the URI, the client can say what method it actually meant. That is,
       as long as it meant one of these:

       ·   GET

       ·   POST

       ·   HEAD

       ·   PUT

       ·   DELETE

       ·   OPTIONS

       ·   TRACE

       ·   CONNECT

       ·   PATCH

       If so, then the "REQUEST_METHOD" in the PSGI environment will be replaced with the
       client's desired value. The original request method is always stored under the
       "plack.original_request_method" key.

Configuration

       These are the named arguments you can pass to "new". Or, more likely, on the "enable" line
       in your "builder" block, as in

          enable 'MethodOverride', header => 'X-HTTP-Method', param => 'my_method';

   "header"
       Specifies the HTTP header name which specifies the overriding HTTP method.

       Defaults to "X-HTTP-Method-Override", as used by Google for its APIs.

   "param"
       Specifies the query parameter name to specify the overriding HTTP method.

       Defaults to "x-tunneled-method".

Acknowledgements

       This module gleefully steals from Catalyst::TraitFor::Request::REST::ForBrowsers by Dave
       Rolsky and the original version by Tatsuhiko Miyagawa (which in turn stole from
       HTTP::Engine::Middleware::MethodOverride). Thanks to Aristotle Pagaltzis
       <http://plasmasturm.org/> for the shove in this direction, to Matt S Trout
       <http://www.trout.me.uk/> for suggesting that it be implemented as middleware, and to Hans
       Dieter Pearcey <http://www.weftsoar.net/> for convincing me not to parse body parameters.
