复习
复习用tcp协议进行远程运行终端。
服务端代码：
1 from socket import * 2 import struct 3 import subprocess 4 tcp_server = socket(AF_INET,SOCK_STREAM) 5 tcp_server.setsockopt(SOL_SOCKET,SO_REUSEADDR,1) 6 tcp_server.bind(('127.0.0.1',8080)) 7 tcp_server.listen(124) 8 while True: 9 coon,addr = tcp_server.accept() 10 while True: 11 cmd = coon.recv(1024) 12 cmd_res = subprocess.Popen(cmd.decode(),shell=True,stdout=subprocess.PIPE,stderr=subprocess.PIPE,stdin=subprocess.PIPE) 13 err = cmd_res.stderr.read() 14 if err: 15 send_res = err 16 else: 17 send_res = cmd_res.stdout.read() 18 length = len(send_res) 19 coon.send(struct.pack('i',length)) 20 coon.send(send_res) 21 # ready = coon.recv(1024) 22 # if ready == b'ready': 23 # coon.send(send_res)
客户端：
1 from socket import * 2 import struct 3 4 tcp_client = socket(AF_INET, SOCK_STREAM) 5 tcp_client.connect(('127.0.0.1', 8080)) 6 while True: 7 cmd = input('请输入指令：') 8 tcp_client.send(cmd.encode()) 9 length = tcp_client.recv(4) 10 length = struct.unpack('i', length)[0] 11 recv_length = 0 12 data = b'' 13 while recv_length < length: 14 data += tcp_client.recv(100) 15 recv_length = len(data) 16 print(data.decode('gbk'))
