This software is a client and server platform based on Twisted that works with protocols beginning with a type and length field.
To create your protocol using LTProtocol, simply construct an LTProtocol with a list of LTMessage objects that specify your protocol. You can use the LTTwistedServer and LTTwistedClient to create a server or client easily. An example of a complete implementation is available for download. You may test it by running Python commands such as, "python test_lpprotocol.py server" or "python test_lpprotocol.py client".
Initially, to use this module, you need to define the messages in your protocol, such as NumMsg and StrMsg. In the example below, NumMsg and StrMsg are two different classes that inherit the LTMessage class providing static methods like get_type() and unpack(), specifying how to pack and unpack data.
Once you receive data through your LTProtocol server or client, you must define a callback method for your protocol, which does something with the data. In the example shown here, the message is simply printed whenever a complete message has arrived.
To create a client, you can create an instance of LTTwistedClient, which takes two main arguments: the LTProtocol object and the callback method. You would then connect this client to the relevant server, providing its IP address and the port.
Similarly, to create a server instance using LTProtocol, you can follow a similar approach: Create an instance of LTTwistedServer, which takes two primary arguments, the LTProtocol object and the relevant callback method. Once constructed, you can use the listen() method to bind the server to a specific port.
To customize the buildProtocol() method of the LTTwistedClient class, you can subclass LTTwistedProtocol and set LTTwistedServer.protocol to your new subclass to have the server send some message to the client when it connects, or to take some special action throughout the connection process.
Overall, LTProtocol is an extraordinary Python module with an intuitive and flexible API that provides you limitless possibilities for building network applications.
