python 使用socket远程发送命令并获得执行结果详解编程语言

#socket_server.py 
  
import socket 
import os 
import sys 
  
def work(): 
        sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM) 
        sock.bind(('0.0.0.0',1000)) 
        sock.listen(5) 
        while True: 
                try: 
                        conn, addr = sock.accept() 
                        ret = conn.recv(2048) 
                        result = os.popen(ret).read() 
                        conn.send(result) 
                except KeyboardInterrupt: 
                        print 'Now we will exit' 
                        sys.exit(0) 
        sock.close() 
  
if __name__ == '__main__': 
        work() 
  
 

socket实例化，并且绑定1000端口，持续进行监听，’0.0.0.0’表示监听本地。sock.listen(backlog)表示可同时监听连 接的数量，一般为5。sock.accept()返回(connection,address)，connection通常用来发送和接收数 据，address是客户端的Internet地址。conn.recv(2048)进行接收数据，然后conn.send(result)将结果送回给 客户端。

#socket_client.py 
  
import socket 
  
def socket_send(command): 
    sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM) 
        sock.connect(('192.168.1.55', 1000)) 
        sock.send(command) 
        result = sock.recv(2048) 
        sock.close() 
        return result 
  
if __name__ == '__main__': 
     print socket_send('ls') 
sock.connect(address)，里面是一个tuple，IP地址和PORT，发送命令给server，然后用result接收结果并进行return
