Name

6       Plack::Middleware::MethodOverride - Override REST methods to Plack apps
7       via POST
8

Version

10       version 0.20
11

Synopsis

13       In your Plack app:
14
15         use Plack::Builder;
16         builder {
17             enable MethodOverride;
18             $app;
19         };
20
21       PUT via a query parameter in your POST forms:
22
23         <form method="POST" action="/foo?x-tunneled-method=PUT">
24           <!-- ... -->
25         </form>
26
27       Or override it via the "X-HTTP-Method-Override" header in a request:
28
29         my $req = HTTP::Request->new(POST => '/foo', [
30             'X-HTTP-Method-Override' => 'PUT'
31         ]);
32

Description

34       Writing REST
35       <http://en.wikipedia.org/wiki/Representational_State_Transfer>ful apps
36       is a good thing, but if you're also trying to support web browsers, it
37       would be nice not to be reduced to "GET" and "POST" for everything.
38
39       This middleware allows for "POST" requests that pretend to be something
40       else: by adding either a header named "X-HTTP-Method-Override" to the
41       request, or a query parameter named "x-tunneled-method" to the URI, the
42       client can say what method it actually meant. That is, as long as it
43       meant one of these:
44
45       ·   GET
46
47       ·   POST
48
49       ·   HEAD
50
51       ·   PUT
52
53       ·   DELETE
54
55       ·   OPTIONS
56
57       ·   TRACE
58
59       ·   CONNECT
60
61       ·   PATCH
62
63       If so, then the "REQUEST_METHOD" in the PSGI environment will be
64       replaced with the client's desired value. The original request method
65       is always stored under the "plack.original_request_method" key.
66

Configuration

68       These are the named arguments you can pass to "new". Or, more likely,
69       on the "enable" line in your "builder" block, as in
70
71          enable 'MethodOverride', header => 'X-HTTP-Method', param => 'my_method';
72
73   "header"
74       Specifies the HTTP header name which specifies the overriding HTTP
75       method.
76
77       Defaults to "X-HTTP-Method-Override", as used by Google for its APIs.
78
79   "param"
80       Specifies the query parameter name to specify the overriding HTTP
81       method.
82
83       Defaults to "x-tunneled-method".

Acknowledgements

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