NAME POE::Component::Client::WebSocket - A POE compatible websocket client VERSION version 0.33 WARNING: Work in progress! Only uploaded early for testing purposes! This module appears to work perfectly, however its not really been tested that much and I will be amazed if there are not bugs. SYNOPSIS #!/usr/bin/env perl use warnings; use strict; use POE qw(Component::Client::WebSocket); POE::Session->create( inline_states => { _start => sub { my $ws = POE::Component::Client::WebSocket->new('wss://echo.websocket.org'); $ws->handler('connected','connected'); $ws->connect; $_[HEAP]->{ws} = $ws; $_[KERNEL]->yield("next") }, next => sub { $_[KERNEL]->delay(next => 1); }, websocket_read => sub { my ($kernel,$read) = @_[KERNEL,ARG0]; print "Read: $read\n"; }, websocket_disconnected => sub { warn "Disconnected"; }, connected => sub { my $req = $_[ARG0]; }, websocket_handshake => sub { my $res = $_[ARG0]; $_[KERNEL]->post( $_[SENDER]->ID, 'send', 1234 ); $_[HEAP]->{ws}->send(5678); }, }, ); POE::Kernel->run(); exit; SUBROUTINES/METHODS new Create a new object, takes 1 argument.. a fully qualified websocket URI. Default handlers and arguments All of these can be changed with the 'handler' function, note the 'event key'. read (websocket_read) event key: read default handler: websocket_read Data that has been read and decoded from the server. disconnected (websocket_disconnected) event key: disconnected default handler: websocket_disconnected Called when the websocket is disconnected. connected (websocket_connected) event key: connected default handler: websocket_connected Called when the websocket is connected (before the handshake) ARG0 contains the HTTP::Request sent. handshake (websocket_handshake) event key: handshake default handler: websocket_handshake Called when the socket handshake is completed, ARG0 contains the HTTP::Response from the server. error (websocket_error) event key: error default handler: websocket_error Called when an error is retrieved, this is a bit vague at the moment ARG0 should contain something. OOP mappings from obj to POE These can be called with a standard POE style POST or directly from the object (see SYNOPSIS for examples of both) connect Start the connection handler Adjust the handlers events are sent to origin Change the origin from the automatically generated one to something else. parent Override the 'send to' parent for the module, by default this is the module that the component was started from. send Send data to the server, arguments are: 1: 'data' the information you want to send. 2: 'type' the type of information to send (default 'text') 3: 'fin' wether to send the 'fin' flag (default 1) 4: 'masked' wether the frame should be masked (default 0) Internal functions (do not call these directly) _start Initial start handler _stop Default stop handler for tidying things up _keep_alive Do not allow the module to stop running _connect Initate a connect to the websocket _handler Adjust the distribution map for handlers _origin Change the origin used in the opening handshake _parent Change the currently targeted session to communicate events with. _send Send a frame encoded request to the server _socket_birth Handle a socket when it connects to something _socket_death Handle a socket when it is disconnected _socket_input Read data from the socket AUTHOR Paul G Webster, "" BUGS Please report any bugs or feature requests to SUPPORT You can find documentation for this module with the perldoc command. perldoc POE::Component::Client::WebSocket You can also look for information at: * GitHub (please report bugs here) * AnnoCPAN: Annotated CPAN documentation * Search MetaCPAN ACKNOWLEDGEMENTS * Tom Ryder - Multiple fixes for version including SNI 0.29 LICENSE AND COPYRIGHT Copyright 2021 Paul G Webster.
