Class IQRegisterHandler

java.lang.Object

org.jivesoftware.openfire.container.BasicModule

org.jivesoftware.openfire.handler.IQHandler

org.jivesoftware.openfire.handler.IQRegisterHandler

All Implemented Interfaces:

ChannelHandler, Module, ServerFeaturesProvider

public class IQRegisterHandler
extends IQHandler
implements ServerFeaturesProvider

Implements the TYPE_IQ jabber:iq:register protocol (plain only). Clients use this protocol to register a user account with the server. A 'get' query runs a register probe to obtain the fields needed for registration. Return the registration form. A 'set' query attempts to create a new user account with information given in the registration form.

Assumptions

This handler assumes that the request is addressed to the server. An appropriate TYPE_IQ tag matcher should be placed in front of this one to route TYPE_IQ requests not addressed to the server to another channel (probably for direct delivery to the recipient).

Compatibility

The current behavior is designed to emulate jabberd1.4. However this behavior differs significantly from JEP-0078 (non-SASL registration). In particular, authentication (IQ-Auth) must return an error when a user request is made to an account that doesn't exist to trigger auto-registration (JEP-0078 explicitly recommends against this practice to prevent hackers from probing for legitimate accounts).

Constructor Detail

IQRegisterHandler

public IQRegisterHandler()

Basic constructor does nothing.

Method Detail

initialize

public void initialize(XMPPServer server)

Description copied from class: BasicModule

Initializes the basic module.

Inheriting classes that choose to override this method MUST call this initialize() method before accessing BasicModule resources.

Specified by:

initialize in interface Module

Overrides:

initialize in class IQHandler

Parameters:

server - the server hosting this module.

handleIQ

public org.xmpp.packet.IQ handleIQ(org.xmpp.packet.IQ packet)
                            throws PacketException,
                                   UnauthorizedException

Description copied from class: IQHandler

Handles the received IQ packet.

Specified by:

handleIQ in class IQHandler

Parameters:

packet - the IQ packet to handle.

Returns:

the response to send back.

Throws:

UnauthorizedException - if the user that sent the packet is not authorized to request the given operation.

PacketException

isInbandRegEnabled

public boolean isInbandRegEnabled()

setInbandRegEnabled

public void setInbandRegEnabled(boolean allowed)

canChangePassword

public boolean canChangePassword()

setCanChangePassword

public void setCanChangePassword(boolean allowed)

getInfo

public IQHandlerInfo getInfo()

Description copied from class: IQHandler

Returns the handler information to help generically handle IQ packets. IQHandlers that aren't local server iq handlers (e.g. chatbots, transports, etc) return null.

Specified by:

getInfo in class IQHandler

Returns:

The IQHandlerInfo for this handler

getFeatures

public Iterator<String> getFeatures()

Description copied from interface: ServerFeaturesProvider

Returns an Iterator (of String) with the supported features by the server. The features to include are the features offered and supported protocols by the SERVER. The idea is that different modules may provide their features that will ultimately be part of the features offered by the server.

Specified by:

getFeatures in interface ServerFeaturesProvider

Returns:

an Iterator (of String) with the supported features by the server.
