服务器客户端通信Python [英] Server Client Communication Python

问题描述

服务器

import socket
import sys
s=socket.socket(socket.AF_INET,socket.SOCK_STREAM)

host= 'VAC01.VACLab.com'
port=int(2000)
s.bind((host,port))
s.listen(1)

conn,addr =s.accept()

data=s.recv(100000)

s.close

客户

import socket
import sys

s=socket.socket(socket.AF_INET,socket.SOCK_STREAM)

host="VAC01.VACLab.com"
port=int(2000)
s.connect((host,port))
s.send(str.encode(sys.argv[1]))

s.close()

我希望服务器接收客户端发送的数据.

I want the server to receive the data that client sends.

尝试此操作时出现以下错误

I get the following error when i try this

客户侧

回溯(最近通话最近): 在第21行的文件"Client.py"中 s.send(sys.argv [1]) TypeError:"str"不支持缓冲区接口

Traceback (most recent call last): File "Client.py", line 21, in s.send(sys.argv[1]) TypeError: 'str' does not support the buffer interface

服务器端

文件"Listener.py"，第23行，在 数据= s.recv(100000) socket.error:[Errno 10057]不允许发送或接收数据的请求 因为未连接套接字，并且(当使用 sendto呼叫)未提供地址

File "Listener.py", line 23, in data=s.recv(100000) socket.error: [Errno 10057] A request to send or receive data was disallowed bec ause the socket is not connected and (when sending on a datagram socket using a sendto call) no address was supplied

推荐答案

在服务器中，您使用 listening 套接字接收数据.它仅用于接受新连接.

In the server, you use the listening socket to receive data. It is only used to accept new connections.

更改为此:

conn,addr =s.accept()

data=conn.recv(100000)  # Read from newly accepted socket

conn.close()
s.close()
