class deluge.core.rpcserver.DelugeRPCProtocol

Bases: twisted.internet.protocol.Protocol

connectionLost(reason)

This method is called when the client is disconnected.

Parameter:reason (str) – the reason the client disconnected.

connectionMade()

This method is called when a new client connects.

dataReceived(data)

Parameter:data (str) – the data from the client. It should be a zlib compressed rencoded string.

dispatch(request_id, method, args, kwargs)

This method is run when a RPC Request is made. It will run the local method and will send either a RPC Response or RPC Error back to the client.

Parameters:

• request_id (int) – the request_id from the client (sent in the RPC Request)
• method (str) – the local method to call. It must be registered with the RPCServer.
• args (list) – the arguments to pass to method
• kwargs (dict) – the keyword-arguments to pass to method

sendData(data)

Sends the data to the client.

Parameter:data – the object that is to be sent to the client. This should be one of the RPC message types.

exception deluge.core.rpcserver.NotAuthorizedError

Bases: deluge.core.rpcserver.DelugeError

class deluge.core.rpcserver.RPCServer(port=58846, interface='', allow_remote=False, listen=True)

Bases: deluge.component.Component

This class is used to handle rpc requests from the client. Objects are registered with this class and their methods are exported using the export decorator.

Parameters:

• port (int) – the port the RPCServer will listen on
• interface (str) – the interface to listen on, this may override the allow_remote setting
• allow_remote (bool) – set True if the server should allow remote connections
• listen (bool) – if False, will not start listening.. This is only useful in Classic Mode

emit_event(event)

Emits the event to interested clients.

Parameter:event (deluge.event.DelugeEvent) – the event to emit

get_method_list()

Returns a list of the exported methods.

Returns:the exported methods Return type:list

get_object_method(name)

Returns a registered method.

Parameter:name (str) – the name of the method, usually in the form of ‘object.method’ Returns:method Raises KeyError:  if name is not registered

This loads the servers cert/private key SSL files for use with the SSL transport.

deluge.core.rpcserver.check_ssl_keys()

Parameters:

• func (function) – the function to export
• auth_level (int) – the auth level required to call this method

deluge.core.rpcserver.generate_ssl_keys()

This method generates a new SSL key/cert.
