internal package Foswiki::Response

Class to encapsulate response data.

Fields: * status - response status * headers - hashref to response headers * body - response body * cookies - hashref to response cookies

ClassMethod new() → $response

Constructs a Foswiki::Response object.

ObjectMethod status( $status ) → $status

Gets/Sets response status.
  • $status is a three digit code, optionally followed by a status string

ObjectMethod charset([$charset]) → $charset

Gets/Sets response charset. If not defined, defaults to ISO-8859-1, just like CGI.pm

ObjectMethod header(-type → $type,

-status => $status, -cookie => $cookie || \@cookies, -attachment => $attachName, -charset => $charset, -expires => $expires, -HeaderN => ValueN? )

Sets response header. Resonably compatible with CGI. Doesn't support -nph, -target and -p3p.

ObjectMethod headers( { ... } ) → $headersHashRef

Gets/Sets all response headers. Keys are headers name and values are scalars for single-valued headers or arrayref for multivalued ones.

ObjectMethod getHeader( [ $name ] ) → $value

If called without parameters returns all present header names, otherwise returns a list (maybe with a single element) of values associated with $name.

ObjectMethod setDefaultHeaders( { $name → $value, ... } )

Sets the header corresponding to the key => value pairs passed in the hash, if the key doesn't already exist, otherwise does nothing. This ensures some default values are entered, but they can be overridden by plugins or other parts in the code.

ObjectMethod printHeaders()

Return a string of all headers, separated by CRLF

ObjectMethod deleteHeader($h1, $h2, ...)

Deletes headers whose names are passed.

ObjectMethod pushHeader( $name, $value )

Adds $value to list of values associated with header $name.

ObjectMethod cookies( [ \@cookies ] ) → @cookies

Gets/Sets response cookies. Parameter, if passed, must be an arrayref.

Elements may be CGI::Cookie objects or raw cookie strings.

WARNING: cookies set this way are not passed in redirects.

ObjectMethod body( [ $body ] ) → $body

Gets/Sets response body. Note: do not use this method for output, use print instead.

ObjectMethod redirect( $uri, $status, $cookies |

-Location => $uri, -Status => $status, -Cookies => $cookies )

Populate object with redirect response headers.

$uri must be passed. Others are optional.

CGI Compatibility Note: It doesn't support -target or -nph

ObjectMethod print(...)

Add content to the end of the body.

ObjectMethod outputHasStarted([$boolean])

Get/set the output-has-started flag. This is used by the Foswiki::Engine to separate header and body output. Once output has started, the headers cannot be changed (though the body can be modified)
