Catalyst::Request - provides information about the current client request
$req = $c->request; $req->action; $req->address; $req->arguments; $req->args; $req->base; $req->body; $req->body_parameters; $req->content_encoding; $req->content_length; $req->content_type; $req->cookie; $req->cookies; $req->header; $req->headers; $req->hostname; $req->input; $req->match; $req->method; $req->param; $req->parameters; $req->params; $req->path; $req->protocol; $req->query_parameters; $req->read; $req->referer; $req->secure; $req->captures; # previously knows as snippets $req->upload; $req->uploads; $req->uri; $req->user; $req->user_agent;
See also Catalyst, Catalyst::Request::Upload.
This is the Catalyst Request class, which provides an interface to data for the current client request. The request object is prepared by Catalyst::Engine, thus hiding the details of the particular engine implementation.
Returns the requested action as a Catalyst::Action object.
Returns the IP address of the client.
Returns a reference to an array containing the arguments.
print $c->request->arguments->[0];
For example, if your action was
package MyApp::C::Foo; sub moose : Local { ... }
and the URI for the request was http://.../foo/moose/bah, the string bah would be the first and only argument.
http://.../foo/moose/bah
bah
Shortcut for arguments.
Contains the URI base. This will always have a trailing slash.
If your application was queried with the URI http://localhost:3000/some/path then base is http://localhost:3000/.
http://localhost:3000/some/path
base
http://localhost:3000/
Returns the message body of the request, unless Content-Type is application/x-www-form-urlencoded or multipart/form-data.
application/x-www-form-urlencoded
multipart/form-data
Returns a reference to a hash containing body (POST) parameters. Values can be either a scalar or an arrayref containing scalars.
print $c->request->body_parameters->{field}; print $c->request->body_parameters->{field}->[0];
These are the parameters from the POST part of the request, if any.
Shortcut for body_parameters.
Shortcut for $req->headers->content_encoding.
Shortcut for $req->headers->content_length.
Shortcut for $req->headers->content_type.
A convenient method to access $req->cookies.
$cookie = $c->request->cookie('name'); @cookies = $c->request->cookie;
Returns a reference to a hash containing the cookies.
print $c->request->cookies->{mycookie}->value;
The cookies in the hash are indexed by name, and the values are CGI::Cookie objects.
Shortcut for $req->headers->header.
Returns an HTTP::Headers object containing the headers for the current request.
print $c->request->headers->header('X-Catalyst');
Returns the hostname of the client.
Alias for $req->body.
This contains the matching part of a Regex action. Otherwise it returns the same as 'action', except for default actions, which return an empty string.
Contains the request method (GET, POST, HEAD, etc).
GET
POST
HEAD
Returns GET and POST parameters with a CGI.pm-compatible param method. This is an alternative method for accessing parameters in $c->req->parameters.
$value = $c->request->param( 'foo' ); @values = $c->request->param( 'foo' ); @params = $c->request->param;
Like CGI, and unlike earlier versions of Catalyst, passing multiple arguments to this method, like this:
$c->request->param( 'foo', 'bar', 'gorch', 'quxx' );
will set the parameter foo to the multiple values bar, gorch and quxx. Previously this would have added bar as another value to foo (creating it if it didn't exist before), and quxx as another value for gorch.
foo
bar
gorch
quxx
Returns a reference to a hash containing GET and POST parameters. Values can be either a scalar or an arrayref containing scalars.
print $c->request->parameters->{field}; print $c->request->parameters->{field}->[0];
This is the combination of query_parameters and body_parameters.
query_parameters
body_parameters
Shortcut for $req->parameters.
Returns the path, i.e. the part of the URI after $req->base, for the current request.
Alias for path, added for compability with CGI.
Returns the protocol (HTTP/1.0 or HTTP/1.1) used for the current request.
Returns a reference to a hash containing query string (GET) parameters. Values can be either a scalar or an arrayref containing scalars.
print $c->request->query_parameters->{field}; print $c->request->query_parameters->{field}->[0];
Reads a chunk of data from the request body. This method is intended to be used in a while loop, reading $maxlength bytes on every call. $maxlength defaults to the size of the request if not specified.
You have to set MyApp->config->{parse_on_demand} to use this directly.
Shortcut for $req->headers->referer. Returns the referring page.
Returns true or false, indicating whether the connection is secure (https).
Returns a reference to an array containing regex captures.
my @captures = @{ $c->request->captures };
captures used to be called snippets. This is still available for backwoards compatibility, but is considered deprecated.
captures
A convenient method to access $req->uploads.
$upload = $c->request->upload('field'); @uploads = $c->request->upload('field'); @fields = $c->request->upload; for my $upload ( $c->request->upload('field') ) { print $upload->filename; }
Returns a reference to a hash containing uploads. Values can be either a hashref or a arrayref containing Catalyst::Request::Upload objects.
my $upload = $c->request->uploads->{field}; my $upload = $c->request->uploads->{field}->[0];
Returns a URI object for the current request. Stringifies to the URI text.
Returns a rewritten URI object for the current request. Key/value pairs passed in will override existing parameters. Unmodified pairs will be preserved.
Returns the currently logged in user. Deprecated. The method recommended for newer plugins is $c->user.
Shortcut to $req->headers->user_agent. Returns the user agent (browser) version string.
