Question

我有套接字问题

import socket

serverName = "herk-PC"
serverPort = 12000

clientSocket = socket.socket(socket.AF_INET,socket.SOCK_DGRAM)

message = input('input lowercase sentence:')

clientSocket.sendto(message.encode('utf-8'),(serverName, serverPort))

modifiedMessage, serverAddress = clientSocket.recvfrom(2048)


print (modifiedMessage.decode('utf-8'))

clientSocket.close()

此代码给我错误

Traceback (most recent call last):
  File "J:\Sistem Jaringan\Task I\client.py", line 12, in <module>
    modifiedMessage, serverAddress = clientSocket.recvfrom(2048)
ConnectionResetError: [WinError 10054] An existing connection was forcibly closed by the remote host

我的错误的任何解决方案？

Answer 1

要么没有服务器在./hash.sh: line 38: e5491a14c7374e7f2ee18e3095f8ac65: command not found ./hash.sh: line 39: e5491a14c7374e7f2ee18e3095f8ac65: command not found（UDP）运行，要么中间有防火墙。在本地计算机上运行服务器，让客户端连接到herk-PC:12000，以确保一切正常。

如果您仍遇到同样的问题，是否在服务器上使用过bind(('localhost',12000))？

Answer 2

#udp_server.py
import socket

bind_host = '127.0.0.1'
bind_port = 7210

sock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
sock.bind((bind_host, bind_port))

data, addr = sock.recvfrom(4096)
print(data.decode('utf-8'), addr[0], ':', addr[1])

udp客户端

Thread.sleep(2000);
External.sendKeys("kevin");
