Detailed Description

This is an implementation of a BOSH (HTTP binding) connection.

Usage:

Client *c = new Client( ... );
c->setConnectionImpl( new ConnectionBOSH( c,
                               new ConnectionTCPClient( c->logInstance(), httpServer, httpPort ),
                               c->logInstance(), boshHost, xmpphost, xmppPort ) );

Make sure to pass the BOSH connection manager's host/port to the transport connection (ConnectionTCPClient in this case), and the XMPP server's host and port to the BOSH connection. You must also pass to BOSH the address of the BOSH server you are dealing with, this is used in the HTTP Host header.

In the case of using ConnectionBOSH through a HTTP proxy, supply httpServer and httpPort as those of the proxy. In all cases, boshHost should be set to the hostname (not IP address) of the server running the BOSH connection manager.

The reason why ConnectionBOSH doesn't manage its own ConnectionTCPClient is that it allows it to be used with other transports (like chained SOCKS5/HTTP proxies, or ConnectionTLS for HTTPS).

Note: To avoid problems, you should disable TLS in gloox by calling ClientBase::setTls( TLSDisabled ).

Sample configurations for different servers can be found in the bosh_example.cpp file included with gloox in the src/examples/ directory.

Member Enumeration Documentation

enum ConnMode

The supported connection modes. Usually auto-detected.

Enumerator
ModeLegacyHTTP	HTTP 1.0 connections, closed after receiving a response
ModePersistentHTTP	HTTP 1.1 connections, re-used after receiving a response
ModePipelining	HTTP Pipelining (implies HTTP 1.1) a single connection is used

Definition at line 110 of file connectionbosh.h.

Constructor & Destructor Documentation

ConnectionBOSH	(	ConnectionBase *	connection,
		const LogSink &	logInstance,
		const std::string &	boshHost,
		const std::string &	xmppServer,
		int	xmppPort = `5222`
	)

Constructs a new ConnectionBOSH object.

Parameters

connection	A transport connection. It should be configured to connect to the BOSH connection manager's (or a HTTP proxy's) host and port, not to the XMPP host. ConnectionBOSH will own the transport connection and delete it in its destructor.
logInstance	The log target. Obtain it from ClientBase::logInstance().
boshHost	The hostname of the BOSH connection manager
xmppServer	A server to connect to. This is the XMPP server's address, not the connection manager's.
xmppPort	The port to connect to. This is the XMPP server's port, not the connection manager's.

Note: To properly use this object, you have to set a ConnectionDataHandler using registerConnectionDataHandler(). This is not necessary if this object is part of a 'connection chain', e.g. with ConnectionSOCKS5Proxy.

Definition at line 31 of file connectionbosh.cpp.

ConnectionBOSH	(	ConnectionDataHandler *	cdh,
		ConnectionBase *	connection,
		const LogSink &	logInstance,
		const std::string &	boshHost,
		const std::string &	xmppServer,
		int	xmppPort = `5222`
	)

Constructs a new ConnectionBOSH object.

Parameters

cdh	An ConnectionDataHandler-derived object that will handle incoming data.
connection	A transport connection. It should be configured to connect to the connection manager's (or proxy's) host and port, not to the XMPP host. ConnectionBOSH will own the transport connection and delete it in its destructor.
logInstance	The log target. Obtain it from ClientBase::logInstance().
boshHost	The hostname of the BOSH connection manager (not any intermediate proxy)
xmppServer	A server to connect to. This is the XMPP server's address, not the connection manager's.
xmppPort	The port to connect to. This is the XMPP server's port, not the connection manager's.

~ConnectionBOSH ( )

virtual

Virtual destructor

Definition at line 76 of file connectionbosh.cpp.

Member Function Documentation

void cleanup ( )

virtual

This function is called after a disconnect to clean up internal state. It is also called by ConnectionBase's destructor.

Reimplemented from ConnectionBase.

Definition at line 345 of file connectionbosh.cpp.

ConnectionError connect ( )

virtual

Used to initiate the connection.

Returns: Returns the connection state.

Implements ConnectionBase.

Definition at line 103 of file connectionbosh.cpp.

void disconnect ( )

virtual

Disconnects an established connection. NOOP if no active connection exists.

Implements ConnectionBase.

Definition at line 121 of file connectionbosh.cpp.

void getStatistics	(	long int &	totalIn,
		long int &	totalOut
	)

virtual

Returns current connection statistics.

Parameters

totalIn	The total number of bytes received.
totalOut	The total number of bytes sent.

Implements ConnectionBase.

Definition at line 353 of file connectionbosh.cpp.

void handleConnect ( const ConnectionBase * connection )

virtual

This function is called when e.g. the raw TCP connection was established.

Parameters

connection The connection.

Implements ConnectionDataHandler.

Definition at line 408 of file connectionbosh.cpp.

void handleDisconnect	(	const ConnectionBase *	connection,
		ConnectionError	reason
	)

virtual

This connection is called when e.g. the raw TCP connection was closed.

Parameters

connection	The connection.
reason	The reason for the disconnect.

Implements ConnectionDataHandler.

Definition at line 435 of file connectionbosh.cpp.

void handleReceivedData	(	const ConnectionBase *	connection,
		const std::string &	data
	)

virtual

This function is called for received from the underlying transport.

Parameters

connection	The connection that received the data.
data	The data received.

Implements ConnectionDataHandler.

Definition at line 359 of file connectionbosh.cpp.

void handleTag ( Tag * tag )

virtual

This function is called when a registered XML element arrives. As with every handler in gloox, the Tag is going to be deleted after this function returned. If you need a copy afterwards, create it using Tag::clone().

Parameters

tag	The complete Tag.

Implements TagHandler.

Definition at line 460 of file connectionbosh.cpp.

ConnectionBase * newInstance ( ) const

virtual

This function returns a new instance of the current ConnectionBase-derived object. The idea is to be able to 'clone' ConnectionBase-derived objects without knowing of what type they are exactly.

Returns: A new Connection* instance.

Implements ConnectionBase.

Definition at line 82 of file connectionbosh.cpp.

ConnectionError receive ( )

virtual

Use this function to put the connection into 'receive mode', i.e. this function returns only when the connection is terminated.

Returns: Returns a value indicating the disconnection reason.

Implements ConnectionBase.

Definition at line 337 of file connectionbosh.cpp.

ConnectionError recv ( int timeout = -1 )

virtual

Use this periodically to receive data from the socket.

Parameters

timeout The timeout to use for select in microseconds. Default of -1 means blocking.

Returns: The state of the connection.

Implements ConnectionBase.

Definition at line 161 of file connectionbosh.cpp.

bool send ( const std::string & data )

virtual

Use this function to send a string of data over the wire. The function returns only after all data has been sent.

Parameters

data	The data to send.

Returns: True if the data has been sent (no guarantee of receipt), false in case of an error.

Implements ConnectionBase.

Definition at line 185 of file connectionbosh.cpp.

void setMode ( ConnMode mode )

inline

Sets the connection mode

Parameters

mode	The connection mode,

See also: ConnMode

Note: In the case that a mode is selected that the connection manager or proxy does not support, gloox will fall back to using HTTP/1.0 connections, which should work with any server.

Definition at line 139 of file connectionbosh.h.

void setPath ( const std::string & path )

inline

Sets the path on the connection manager to request

Parameters

path	The path, the default is "/http-bind/", which is the default for many connection managers.

Definition at line 130 of file connectionbosh.h.

void setServer	(	const std::string &	xmppHost,
		unsigned short	xmppPort = `5222`
	)

inline

Sets the XMPP server to proxy to.

Parameters

xmppHost	The XMPP server hostname (IP address).
xmppPort	The XMPP server port.
