【问题描述】：

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()

这段代码给我错误

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

我的错误有什么解决办法吗？

【解决方案1】：

要么您没有在 herk-PC:12000 (UDP) 上运行的服务器，要么两者之间有防火墙。在您的本地计算机上运行服务器并让客户端连接到localhost:12000，以确保一切正常。

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

【解决方案2】：

#udp_client.py
import socket

target_host = '127.0.0.1'
target_port = 7210

client = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
nBytes = client.sendto('ABCDEF'.encode('utf-8'), (target_host, target_port))
print(nBytes, 'Bytes', 'Send OK')`

udp 客户端

#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_server
