    . FreeOpcUa/python-opcua
        https://github.com/FreeOpcUa/python-opcua

二、Test Code
    . Minimal client example: https://github.com/FreeOpcUa/python-opcua/blob/master/examples/client-minimal.py
    . Minimal server example: https://github.com/FreeOpcUa/python-opcua/blob/master/examples/server-minimal.py

三、Run Code
    . Server：
        root@localhost:/home/zengjf/opcua# python3 server-minimal.py
        Listening on 0.0.0.0:
        Cleanup client connection:  ('127.0.0.1', )
    . Client
        root@localhost:/home/zengjf/opcua# python3 client-minimal.py
        Objects node is:  Node(TwoByteNodeId(i=))
        Children of root are:  [Node(NumericNodeId(i=)), Node(NumericNodeId(i=)), Node(NumericNodeId(i=))]
        myvar is:  Node(NumericNodeId(ns=;i=))
