简单的远程操作

服务器端：

__author__ = 'armyz'

import socket,os
server = socket.socket()
server.bind(("localhost",9999))

server.listen()

while True:
    conn,addr = server.accept()
    print("new conn:",addr)
    while True:
        print("接收指令开始")
        data = conn.recv(1024)
        if not data:
            print("客户端已经断开")
            break
        print("执行指令：",data)
        if data.decode() == "cmd":
            print("不能使用cmd")
            data = b'ver'
        cmd_res = os.popen(data.decode()).read()
        print(type(cmd_res))
        print("结果返回",len(cmd_res))
        if len(cmd_res) == 0 :
            cmd_res = "错误的指令"
        conn.send(str(len(cmd_res.encode("utf-8"))).encode("utf-8"))
        client_ack = conn.recv(512) #接收一下消息
        conn.send(cmd_res.encode("utf-8"))
        print("指令成功返回")
server.close()

 

客户端：

__author__ = 'armyz'
import socket
client = socket.socket()

client.connect(("localhost",9999))

while True:
    cmd = input(">>:").strip()
    if len(cmd) == 0:continue
    client.send(cmd.encode("utf-8"))
    cmd_res_size = client.recv(1024)
    print("命令结果大小：",cmd_res_size)
    client.send(b"ok")
    received_size = 0
    received_date = b""
    while received_size < int(cmd_res_size.decode()):
        data = client.recv(1024)
        received_size += len(data)
        received_date += data
    else:
        print("cmd res receive done...!",received_size)
        print(received_date.decode())
client.close()

 

发现调用是窗口，就卡在哪里了。这里先MARK一下，以后深入学习后，再回头来看看。

发现写Python越来越有意思了！
