NAME Plack::Middleware::MethodOverride - Override REST methods to Plack apps via POST 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 X-HTTP-Method-Override header in a request: my $req = HTTP::Request->new(POST => '/foo', [ 'X-HTTP-Method-Override' => 'PUT' ]); DESCRIPTION Writing REST 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.
