{
    "command": "connect",
    "host":"127.0.0.1",
    "port":80
}
{
    "command": "send",
    "data":"GET / HTTP/1.1\r\nHost: 127.0.0.1\r\nConnection: close\r\n\r\n"
}
{
    "command": "close"
}

{
    "success": true,
    "code": -1,
    "message": "recv data",
    "data": []
}

As the example above:    
- "message" field is for human.   
- "success" field can be ignored.     

when "code" field = -1, "data" field is presented.     
    that means ws2s_server received data from peer. "data" is a int array, each element represents a byte.     

when "code" field = 0.      
    usually means ws2s_server successfully completed the most recent command    

when "code" field > 0.      
    means something is not normal:      
    when "code" = 1:    
        unknown exception, you can submit an issue to ws2s    

    when "code" = 2:    
        ConnectionRefusedError raisesd when ws2s_server try to   
        connect host:port you specified    

    when "code" = 3:    
        IllegalSocketState, just reSend an "connect" request like:    
        {"command":"connect","host":"127.0.0.1","port":80}    

    when "code" = 4:    
        usually means you want ws2s_server to connect 127.0.0.1,    
        but ws2s_server refused to do that     
    
    when "code" = 5:    
        socket connection closed by socket server you connected to
