Python Socket - Send/Receive messages at the same

问题:

Basically I have been working on a simple chat room using socket and thread. In my client I can receive and send messages, my issue is that one comes before another in a loop, so if I am sending a message I will only receive data once I have sent a message. I want it to work like any other chat room, where I could receive a message when I am sending a message, any help will help greatly. This is my basic client:

import socket
import sys

###########
HOST = '25.0.18.52'
PORT = 9999
###########

name = input("Enter your name: ")
s = socket.socket()
s.connect((HOST,PORT))

while 1:
    message = input("Message: ")
    s.send("{}: {}".format(name, message).encode('utf-8'))
    data = s.recv(1024)
    a = data.decode("utf-8") 
    print(a)

回答1:

You should keep 2 threads: one for listening and the other for receiving. In your while loop, you should remove the listener part, and keep the code in a different thread. This way you can receive and type on the console at the same time.

def recv():
    while True:
         data = s.recv(1024).decode()
         if not data: sys.exit(0)
         print data

Thread(target=recv).start()
