Net::XMPP::Client(3pm) User Contributed Perl Documentation Net::XMPP::Client(3pm)
NAME
Net::XMPP::Client - XMPP Client Module
SYNOPSIS
Net::XMPP::Client is a module that provides a developer easy access to the Extensible
Messaging and Presence Protocol (XMPP).
DESCRIPTION
Client.pm uses Protocol.pm to provide enough high level APIs and automation of the low
level APIs that writing an XMPP Client in Perl is trivial. For those that wish to work
with the low level you can do that too, but those functions are covered in the
documentation for each module.
Net::XMPP::Client provides functions to connect to an XMPP server, login, send and receive
messages, set personal information, create a new user account, manage the roster, and
disconnect. You can use all or none of the functions, there is no requirement.
For more information on how the details for how Net::XMPP is written please see the help
for Net::XMPP itself.
For a full list of high level functions available please see Net::XMPP::Protocol.
Basic Functions
use Net::XMPP;
$Con = Net::XMPP::Client->new();
$Con->SetCallbacks(...);
$Con->Execute(hostname=>"jabber.org",
username=>"bob",
password=>"XXXX",
resource=>"Work"
);
For the list of available functions see Net::XMPP::Protocol.
$Con->Disconnect();
METHODS
Basic Functions
new
new(debuglevel=>0|1|2,
debugfile=>string,
debugtime=>0|1)
creates the Client object. debugfile should be set to the path for the debug log to be
written. If set to "stdout" then the debug will go there. debuglevel controls the amount
of debug. For more information about the valid setting for debuglevel, debugfile, and
debugtime see Net::XMPP::Debug.
Connect
Connect(hostname=>string,
port=>integer,
timeout=>int,
connectiontype=>string,
tls=>0|1,
srv=>0|1,
componentname=>string)
opens a connection to the server listed in the hostname (default localhost), on the port
(default 5222) listed, using the connectiontype listed (default tcpip). The two
connection types available are:
tcpip standard TCP socket
http TCP socket, but with the
headers needed to talk
through a web proxy
If you specify tls, then it TLS will be used if it is available as a feature.
If srv is specified AND Net::DNS is installed and can be loaded, then an SRV query is sent
to srv.hostname and the results processed to replace the hostname and port. If the lookup
fails, or Net::DNS cannot be loaded, then hostname and port are left alone as the
defaults.
Alternatively, you may manually specify componentname as the domain portion of the jid and
leave hostname set to the actual hostname of the XMPP server.
Execute
Execute(hostname=>string,
port=>int,
tls=>0|1,
username=>string,
password=>string,
resource=>string,
register=>0|1,
connectiontype=>string,
connecttimeout=>string,
connectattempts=>int,
connectsleep=>int,
processtimeout=>int)
Generic inner loop to handle connecting to the server, calling Process, and reconnecting
if the connection is lost. There are five callbacks available that are called at various
places:
onconnect - when the client has
made a connection.
onauth - when the connection is
made and user has been
authed. Essentially,
this is when you can
start doing things
as a Client. Like
send presence, get your
roster, etc...
onprocess - this is the most
inner loop and so
gets called the most.
Be very very careful
what you put here
since it can
*DRASTICALLY* affect
performance.
ondisconnect - when the client
disconnects from
the server.
onexit - when the function gives
up trying to connect and
exits.
The arguments are passed straight on to the Connect function, except for connectattempts
and connectsleep. connectattempts is the number of times that the Component should try to
connect before giving up. -1 means try forever. The default is -1. connectsleep is the
number of seconds to sleep between each connection attempt.
If you specify register=>1, then the Client will attempt to register the sepecified
account for you, if it does not exist.
Process
Process(integer)
takes the timeout period as an argument. If no timeout is listed then the function blocks
until a packet is received. Otherwise it waits that number of seconds and then exits so
your program can continue doing useful things. NOTE: This is important for GUIs. You
need to leave time to process GUI commands even if you are waiting for packets. The
following are the possible return values, and what they mean:
1 - Status ok, data received.
0 - Status ok, no data received.
undef - Status not ok, stop processing.
IMPORTANT: You need to check the output of every Process. If you get an undef then the
connection died and you should behave accordingly.
Disconnect
Disconnect()
closes the connection to the server.
Connected
Connected()
returns 1 if the Transport is connected to the server, and 0 if not.
