Based on study day 67 python tcp instantiate remote command execution

Use conduit for communication between two procedures: For example: QQ and micro-channel communication

Server:

Socket * Import from 
Import The subprocess # ducting module, communications among different programs 
for ip_port = "127.0.0.1", 8080 
The back_log. 5 = 
buffer_size = 1024 

tcp_server = Socket (AF_INET, SOCK_STREAM) 
tcp_server.bind (for ip_port) 
tcp_server.listen (. 5) 
True the while: 
    conn, addr = tcp_server.accept () 
    Print ( "new client link", addr) 
    the while True: 
        the try: 
            cnd = conn.recv (buffer_size) 
            IF not cnd: BREAK 
            Print ( "client received the command" , CND) 

            # run run give cnd_res 
            RES = subprocess.Popen (cnd.decode ( "UTF-. 8"), the shell = True, the information is encapsulated into # duct inside 
                                 stderr = subprocess.PIPE, # get the wrong information Official Road inside
                                 subprocess.PIPE = stdin, 
                                 stdout = subprocess.PIPE) 
            ERR = res.stderr.read () 
            IF ERR: 
                cnd_res ERR = 
            the else: 
                cnd_res = res.stdout.read () ## to read the correct information from the running inside Guandao out 

            # to run correctly good command to the client 
            conn.send (cnd_res) 
        the except Exception AS E: 
            Print (E) 
            BREAK 
        conn.Close ()

Client:

* Import socket from 
ip_port = "127.0.0.1", 8080 
back_log = 5 
buffer_size = 1024 

tcp_clint = socket (AF_INET, SOCK_STREAM) 
tcp_clint.connect (ip_port) 
the while True: 
    cnd the INPUT = ( ">>>:") Strip (. ) 
    IF not cnd: the Continue # can not be empty 
    if cnd == "quit": continue # press to exit, the exit is allowed 
    tcp_clint.send (cnd.encode ( "UTF-8")) 
    cnd_res = tcp_clint.recv (buffer_size) 
    Print ( "execution result of the command is:", cnd_res.decode ( "gbk" )) # server sends all over not specify the encoding using a coding system, Windows default encoding is GBK 
tcp_clint.close ()
