NAME

       Net::SIP::Request - handling of SIP request packets

SYNOPSIS

         my $req = Net::SIP::Request->new( 'INVITE',... );
         my $ack = $req->create_ack();

DESCRIPTION

       Subclass of Net::SIP::Packet for handling request packets.  Has methods to create
       responses to requests and to authorize requests.

EXAMPLES

         # create INVITE request
         my $invite = Net::SIP::Request->new(
               'INVITE', 'sip:you@example.com',
               { from => ..., to => ... },
               Net::SIP::SDP->new( ... )
         );

         # somehow send request and retrieve response $resp
         ...
         if ( $resp->code eq '401' or $resp->code eq '407' ) {
               # need to authorize request
               $invite->authorize( $resp, [ username, password ] );

               # somehow send again and retrieve response $resp
               ...
         }

         if ( $resp->code ~m{^[2345]\d\d} ) {
               # got final response, send ACK
               my $ack = $invite->create_ack( $resp );

               # somehow send $ack
               ...
         }

CONSTRUCTOR

       Inherited from Net::SIP::Packet. See there.

METHODS

       method
           Get method of request.

       uri Get URI part of request.

       set_uri ( STRING )
           Set URI of request to STRING

       set_cseq ( NUMBER )
           Set sequence number if "CSeq" header to NUMBER.

       create_ack ( RESPONSE )
           Returns Net::SIP::Request object for ACK request for the case when Net::SIP::Response
           RESPONSE was received in reply for packet $self.

       create_cancel
           Returns Net::SIP::Request object to cancel request in $self.

       create_response ( CODE, [MSG,] [ \%HEADER, BODY ] )
           Returns Net::SIP::Response packet for the received request $self with numerical code
           CODE and text message MSG. Header for the response will be based on the request, but
           can be added or overridden using \%HEADER.  If MSG is not given (e.g. argument is
           missing, second argument is \%HEADER already) a builtin message for the code will be
           used.

           For details to \%HEADER and BODY see new_from_parts in Net::SIP::Packet.

       authorize ( RESPONSE, AUTH )
           Tries to authorize request $self based on the information in RESPONSE (a 401 or 407
           "Authorization required" response) and AUTH. AUTH is either "[ user,pass ]" if a
           global authorization info exists for all realms or "{ realm1 => [ user1,pass1 ],
           realm2 => [ user2,pass2 ],... }" if different credentials are provided for different
           realms or a callback "callback(realm)->[user,pass]".  The realms, for which
           authorization is needed, are read from RESPONSE.

           The request $self is modified in-place. If a modification occurred, e.g.  if (parts
           of) the authorization requests could be resolved it will return TRUE, else FALSE.

           Supports only RFC2617 with md5 and empty qop or qop 'auth', not md5-sess or qop's like
           'auth-int'.
