Note that the LWP library uses HTTP style requests even for non-HTTP protocols. Instances of this class are usually passed to the request() method of an C object. C is a subclass of C and therefore inherits its methods. The following additional methods are available: =over 4 =item $r = HTTP::Request->new( $method, $uri ) =item $r = HTTP::Request->new( $method, $uri, $header ) =item $r = HTTP::Request->new( $method, $uri, $header, $content ) Constructs a new C object describing a request on the object $uri using method $method. The $method argument must be a string. The $uri argument can be either a string, or a reference to a C object. The optional $header argument should be a reference to an C object or a plain array reference of key/value pairs. The optional $content argument should be a string of bytes. =item $r = HTTP::Request->parse( $str ) This constructs a new request object by parsing the given string. =item $r->method =item $r->method( $val ) This is used to get/set the method attribute. The method should be a short string like "GET", "HEAD", "PUT" or "POST". =item $r->uri =item $r->uri( $val ) This is used to get/set the uri attribute. The $val can be a reference to a URI object or a plain string. If a string is given, then it should be parseable as an absolute URI. =item $r->header( $field ) =item $r->header( $field => $value ) This is used to get/set header values and it is inherited from C via C. See L for details and other similar methods that can be used to access the headers. =item $r->accept_decodable This will set the C header to the list of encodings that decoded_content() can decode. =item $r->content =item $r->content( $bytes ) This is used to get/set the content and it is inherited from the C base class. See L for details and other methods that can be used to access the content. Note that the content should be a string of bytes. Strings in perl can contain characters outside the range of a byte. The C module can be used to turn such strings into a string of bytes. =item $r->as_string =item $r->as_string( $eol ) Method returning a textual representation of the request. =back =head1 SEE ALSO L, L, L, L =head1 COPYRIGHT Copyright 1995-2004 Gisle Aas.
