Question

我正在尝试在2 RPI3，完全之间开始聊天，如图所示 https://www.raspberrypi.org/learning/networking-lessons/lesson-1/worksheet/

这两种设备都具有独特的IP，并且相互成功。
两台设备成功运行chat.py（一台作为服务器chat.py和一台客户机chat.py 192.168.0.2

但是每个终端上键入的文字都没有通过。

任何想法为什么？

这是chat.py代码：

import network
import sys

def heard(phrase):
  print("them:" + phrase)

if (len(sys.argv) >= 2):
  network.call(sys.argv[1], whenHearCall=heard)
else:  
  network.wait(whenHearCall=heard)

while network.isConnected():
  #phrase = raw_input() #python2
  phrase = input() # python3
  print("me:" + phrase)
  network.say(phrase)

服务器文件：

import socket

def Main():
host = "127.0.0.1"
port = 5000

mySocket = socket.socket()
mySocket.bind((host,port))
mySocket.listen(2)
conn, addr = mySocket.accept()
print ("Connection from: " + str(addr))
varz=["var1","var2","var3"]
while True:
        data = conn.recv(1024).decode()
        if data in varz[0] :
           print("YES!")
        print(data.split(' '))
        if not data:
                break
        print ("from connected  user: " + str(data))

        data = str(data[0:2]).upper()
        print ("sending: " + str(data))
        conn.send(data.encode())

conn.close()

if __name__ == '__main__':
  Main()

客户档案：

import socket

def Main():
    host = '127.0.0.1'
    port = 0


    mySocket = socket.socket()
    mySocket.connect((host,5000))
    user1=input("type usename:") 
    message = input("%s: "%user1)

    while message != 'q':
            mySocket.send(message.encode())
            data = mySocket.recv(1024).decode()

            print ('Received from server: ' + data)

            message = input("%s: "%user1)

    mySocket.close()

  if __name__ == '__main__':
   Main()
