\&\f(CW\*(C`HTTP::Request\*(C'\fR is a class encapsulating \s-1HTTP\s0 style requests,
consisting of a request line, some headers, and a content body. Note
that the \s-1LWP\s0 library uses \s-1HTTP\s0 style requests even for non-HTTP
protocols.  Instances of this class are usually passed to the
\&\fIrequest()\fR method of an \f(CW\*(C`LWP::UserAgent\*(C'\fR object.
.PP
\&\f(CW\*(C`HTTP::Request\*(C'\fR is a subclass of \f(CW\*(C`HTTP::Message\*(C'\fR and therefore
inherits its methods.  The following additional methods are available:
.ie n .IP "$r\fR = HTTP::Request\->new( \f(CW$method\fR, \f(CW$uri )" 4
.el .IP "\f(CW$r\fR = HTTP::Request\->new( \f(CW$method\fR, \f(CW$uri\fR )" 4
.IX Item "$r = HTTP::Request->new( $method, $uri )"
.PD 0
.ie n .IP "$r\fR = HTTP::Request\->new( \f(CW$method\fR, \f(CW$uri\fR, \f(CW$header )" 4
.el .IP "\f(CW$r\fR = HTTP::Request\->new( \f(CW$method\fR, \f(CW$uri\fR, \f(CW$header\fR )" 4
.IX Item "$r = HTTP::Request->new( $method, $uri, $header )"
.ie n .IP "$r\fR = HTTP::Request\->new( \f(CW$method\fR, \f(CW$uri\fR, \f(CW$header\fR, \f(CW$content )" 4
.el .IP "\f(CW$r\fR = HTTP::Request\->new( \f(CW$method\fR, \f(CW$uri\fR, \f(CW$header\fR, \f(CW$content\fR )" 4
.IX Item "$r = HTTP::Request->new( $method, $uri, $header, $content )"
.PD
Constructs a new \f(CW\*(C`HTTP::Request\*(C'\fR object describing a request on the
object \f(CW$uri\fR using method \f(CW$method\fR.  The \f(CW$method\fR argument must be a
string.  The \f(CW$uri\fR argument can be either a string, or a reference to a
\&\f(CW\*(C`URI\*(C'\fR object.  The optional \f(CW$header\fR argument should be a reference to
an \f(CW\*(C`HTTP::Headers\*(C'\fR object or a plain array reference of key/value
pairs.  The optional \f(CW$content\fR argument should be a string of bytes.
.ie n .IP "$r\fR = HTTP::Request\->parse( \f(CW$str )" 4
.el .IP "\f(CW$r\fR = HTTP::Request\->parse( \f(CW$str\fR )" 4
.IX Item "$r = HTTP::Request->parse( $str )"
This constructs a new request object by parsing the given string.
.ie n .IP "$r\->method" 4
.el .IP "\f(CW$r\fR\->method" 4
.IX Item "$r->method"
.PD 0
.ie n .IP "$r\fR\->method( \f(CW$val )" 4
.el .IP "\f(CW$r\fR\->method( \f(CW$val\fR )" 4
.IX Item "$r->method( $val )"
.PD
This is used to get/set the method attribute.  The method should be a
short string like \*(L"\s-1GET\s0\*(R", \*(L"\s-1HEAD\s0\*(R", \*(L"\s-1PUT\s0\*(R" or \*(L"\s-1POST\s0\*(R".
.ie n .IP "$r\->uri" 4
.el .IP "\f(CW$r\fR\->uri" 4
.IX Item "$r->uri"
.PD 0
.ie n .IP "$r\fR\->uri( \f(CW$val )" 4
.el .IP "\f(CW$r\fR\->uri( \f(CW$val\fR )" 4
.IX Item "$r->uri( $val )"
.PD
This is used to get/set the uri attribute.  The \f(CW$val\fR can be a
reference to a \s-1URI\s0 object or a plain string.  If a string is given,
then it should be parseable as an absolute \s-1URI\s0.
.ie n .IP "$r\fR\->header( \f(CW$field )" 4
.el .IP "\f(CW$r\fR\->header( \f(CW$field\fR )" 4
.IX Item "$r->header( $field )"
.PD 0
.ie n .IP "$r\fR\->header( \f(CW$field\fR => \f(CW$value )" 4
.el .IP "\f(CW$r\fR\->header( \f(CW$field\fR => \f(CW$value\fR )" 4
.IX Item "$r->header( $field => $value )"
.PD
This is used to get/set header values and it is inherited from
\&\f(CW\*(C`HTTP::Headers\*(C'\fR via \f(CW\*(C`HTTP::Message\*(C'\fR.  See HTTP::Headers for
details and other similar methods that can be used to access the
headers.
.ie n .IP "$r\->content" 4
.el .IP "\f(CW$r\fR\->content" 4
.IX Item "$r->content"
.PD 0
.ie n .IP "$r\fR\->content( \f(CW$content )" 4
.el .IP "\f(CW$r\fR\->content( \f(CW$content\fR )" 4
.IX Item "$r->content( $content )"
.PD
This is used to get/set the content and it is inherited from the
\&\f(CW\*(C`HTTP::Message\*(C'\fR base class.  See HTTP::Message for details and
other methods that can be used to access the content.
.Sp
Note that the content should be a string of bytes.  Strings in perl
can contain characters outside the range of a byte.  The \f(CW\*(C`Encode\*(C'\fR
module can be used to turn such strings into a string of bytes.
.ie n .IP "$r\->as_string" 4
