Net::XMPP3::Client - XMPP Client Module
Net::XMPP3::Client is a module that provides a developer easy access
to the Extensible Messaging and Presence Protocol (XMPP).
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::XMPP3::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::XMPP3 is written
please see the help for Net::XMPP3 itself.
For a full list of high level functions available please see
$Con = new Net::XMPP3::Client();
# For the list of available functions see Net::XMPP3::Protocol.
new(debuglevel=>0|1|2, - creates the Client object. debugfile
debugfile=>string, should be set to the path for the debug
debugtime=>0|1) 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
Connect(hostname=>string, - opens a connection to the server
port=>integer, listed in the hostname (default
timeout=>int localhost), on the port (default
connectiontype=>string, 5222) listed, using the
tls=>0|1) connectiontype listed (default
tcpip). The two connection types
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.
Execute(hostname=>string, - Generic inner loop to handle
port=>int, connecting to the server, calling
tls=>0|1, Process, and reconnecting if the
username=>string, connection is lost. There are
password=>string, five callbacks available that are
resource=>string, called at various places:
register=>0|1, onconnect - when the client has
connectiontype=>string, made a connection.
connecttimeout=>string, onauth - when the connection is
connectattempts=>int, made and user has been
connectsleep=>int, authed. Essentially,
processtimeout=>int) this is when you can
start doing things
as a Client. Like
send presence, get your
onprocess - this is the most
inner loop and so
gets called the most.
Be very very careful
what you put here
since it can
ondisconnect - when the client
onexit - when the function gives
up trying to connect and
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
If you specify register=>1, then the
Client will attempt to register the
sepecified account for you, if it
does not exist.
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() - closes the connection to the server.
Connected() - returns 1 if the Transport is connected to the server,
and 0 if not.
