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

=head1 Synopsis

In your Plack app:

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

PUT via a query parameter in your POST forms:

  

    
  


Or override it via the C header in a request:

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

=head1 Description

Writing
Lful apps
is a good thing, but if you're also trying to support web browsers, it would
be nice not to be reduced to C and C for everything.

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

=over

=item * GET

=item * POST

=item * HEAD

=item * PUT

=item * DELETE

=item * OPTIONS

=item * TRACE

=item * CONNECT

=item * PATCH

=back

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

=head1 Configuration

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

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

=head2 C


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

Defaults to C, as used by Google for its APIs.

=head2 C

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

Defaults to C.

=head1 Acknowledgements

This module gleefully steals from
L by Dave Rolsky and the
original version by Tatsuhiko Miyagawa (which in turn stole from
L). Thanks to L for the shove in this direction, to L for suggesting that it be implemented as
middleware, and to L for
convincing me not to parse body parameters.
