Python 简单的远程执行命令

client端执行命令，server端返回命令结果

# server 端
import socket, subprocess

sk = socket.socket()
address=(\'127.0.0.1\', 8000)
sk.bind(address)
sk.listen(3)
print(\'waiting....\')

while 1:
    conn, addr = sk.accept()
    print(addr)
    while 1:
        try:
            data = conn.recv(1024)
        except Exception:
            break
        if not data: break
        print(\'.........\', str(data, \'utf8\'))

        obj = subprocess.Popen(data.decode(\'utf8\'), shell=True, stdout=subprocess.PIPE)
        cmd_result = obj.stdout.read()
        result_len = bytes(str(len(cmd_result)), \'utf8\')
        print(\'>>>>>>\', result_len)
        conn.sendall(result_len)
        conn.recv(1024)              # 预防粘包现象
        conn.sendall(cmd_result)

sk.close()

# client 端
import socket

sk = socket.socket()
print(sk)

address = (\'127.0.0.1\', 8000)
sk.connect(address)

while True:
    inp = input(\'>>>\')
    if inp == \'exit\':
        break
    sk.send(bytes(inp, \'utf8\'))
    result_len = int(str(sk.recv(1024), \'utf8\'))
    sk.sendall(bytes(\'ok\', \'utf8\'))
    print(result_len)
    data = bytes()
    while len(data) != result_len:
        recv = sk.recv(1024)
        data += recv
    print(str(data, \'gbk\'))
sk.close()
