SYNOPSIS

11         sub psgi_handler {
12             my $env = shift;
13
14             my $res = Plack::Response->new(200);
15             $res->content_type('text/html');
16             $res->body("Hello World");

19         }

DESCRIPTION

22       Plack::Response allows you a way to create PSGI response array ref
23       through a simple API.
24

METHODS

26       new
27             $res = Plack::Response->new;
28             $res = Plack::Response->new($status);
29             $res = Plack::Response->new($status, $headers);
30             $res = Plack::Response->new($status, $headers, $body);
31
32           Creates a new Plack::Response object.
33
34       status
35             $res->status(200);
36             $status = $res->status;
37
38           Sets and gets HTTP status code. "code" is an alias.
39
40       headers
41             $headers = $res->headers;
42             $res->headers([ 'Content-Type' => 'text/html' ]);
43             $res->headers({ 'Content-Type' => 'text/html' });
44             $res->headers( HTTP::Headers::Fast->new );
45
46           Sets and gets HTTP headers of the response. Setter can take either
47           an array ref, a hash ref or HTTP::Headers::Fast object containing a
48           list of headers.
49
50       body
51             $res->body($body_str);
52             $res->body([ "Hello", "World" ]);
53             $res->body($io);
54
55           Gets and sets HTTP response body. Setter can take either a string,
56           an array ref, or an IO::Handle-like object. "content" is an alias.
57
58           Note that this method doesn't automatically set Content-Length for
59           the response. You have to set it manually if you want, with the
60           "content_length" method (see below).
61
62       header
63             $res->header('X-Foo' => 'bar');
64             my $val = $res->header('X-Foo');
65
66           Shortcut for "$res->headers->header".
67
68       content_type, content_length, content_encoding
69             $res->content_type('text/plain');
70             $res->content_length(123);
71             $res->content_encoding('gzip');
72
73           Shortcut for the equivalent get/set methods in "$res->headers".
74
75       redirect
76             $res->redirect($url);
77             $res->redirect($url, 301);
78
79           Sets redirect URL with an optional status code, which defaults to
80           302.
81
82           Note that this method doesn't normalize the given URI string. Users
83           of this module have to be responsible about properly encoding URI
84           paths and parameters.
85
86       location
87           Gets and sets "Location" header.
88
89           Note that this method doesn't normalize the given URI string in the
90           setter. See above in "redirect" for details.
91
92       cookies
93             $res->cookies->{foo} = 123;
94             $res->cookies->{foo} = { value => '123' };
95
96           Returns a hash reference containing cookies to be set in the
97           response. The keys of the hash are the cookies' names, and their
98           corresponding values are a plain string (for "value" with
99           everything else defaults) or a hash reference that can contain keys
100           such as "value", "domain", "expires", "path", "httponly", "secure",
101           "max-age".
102
103           "expires" can take a string or an integer (as an epoch time) and
104           does not convert string formats such as "+3M".
105
106             $res->cookies->{foo} = {
107                 value => 'test',
108                 path  => "/",
109                 domain => '.example.com',
110                 expires => time + 24 * 60 * 60,
111             };
112
113       finalize
114             $res->finalize;
115
116           Returns the status code, headers, and body of this response as a
117           PSGI response array reference.
118
119       to_app
120             $app = $res->to_app;
121
122           A helper shortcut for "sub { $res->finalize }".
