UDP套接字服务器正在侦听时终端中的Python键盘输入

发布于08月03日

在接收传入的UDP数据时，如何在终端中发送基于键盘输入的Socket数据？按下包含换行符的enter键后，数据将通过套接字发送.

我只有这个最小的UDP服务器:

import socket
SERV_IPV4, SERV_PORT = ("192.168.43.150", 7777)
udpSock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
udpSock.bind((SERV_IPV4,SERV_PORT))

while 1:
  dataRecv, CLNT_ADDR = udpSock.recvfrom(1024)
  print(dataRecv, CLNT_ADDR)

我对程序的期望是无关紧要的，就像Netcat命令如何工作:nc -ulp 7777

推荐答案

Use Threading个

import socket, threading
SERV_IPV4, SERV_PORT = ("192.168.43.150", 7777)
udpSock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
udpSock.bind((SERV_IPV4,SERV_PORT))

dataRecv = ""
CLNT_ADDR = None

def receiveData():
  global CLNT_ADDR
  global dataRecv
  while (1):
    dataRecv, CLNT_ADDR = udpSock.recvfrom(1024)
    print(dataRecv, CLNT_ADDR)

recvThread = threading.Thread(target=receiveData)
recvThread.start()
recvThread.join(0)

while (1):
  dataSend = (input() + "\n").encode()
  print(dataSend)
  udpSock.sendto(dataSend,CLNT_ADDR)
