Question

我对recv()有疑问它总是返回[][][][][][][][][][][][][][]...

在一行：chat = eval(s.recv(1024).decode("utf-8"))中，eval提供了错误。

我该如何解决？

server.py

import socket
import threading

host = "localhost"
port = 12345

chat = []

try:
    s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    print("socket created")

    s.bind((host, port)) 
    print("socket connected {} port".format(port))

    s.listen(5)      
    print("socket listening")
except socket.error as msg:
    print("Error:",msg)


clients = []


def accept():
    while True:
        global clients
        client,addr = s.accept()
        print('Gelen bağlantı:', addr)
        clients.append(client)
        client.send(str(chat).encode("utf-8"))


def new_message():
    while True:
        for c in clients:
            message = c.recv(1024)
            if message:
                chat.append(message)

threading.Thread(target=accept).start()
threading.Thread(target=new_message).start()



while True:
    for c in clients:
        c.send(str(chat).encode("utf-8"))

Client.py

import socket
import time
from tkinter import *
import os
import threading

s = socket.socket()          

host = "localhost"
port = 12345                


try:

    s.connect((host, port)) 

except socket.error as msg:
    print("[Server not enabled.] Message:", msg)
    while True:
        pass


def render_screen():
    print(s.recv(1024).decode("utf-8"))
    while True:
        time.sleep(0.1)
        os.system("cls")
        chat = eval(s.recv(1024).decode("utf-8"))
        for i in list(chat):
            print(i)

def send():
    new_message = send_box.get()
    s.send(str(new_message).encode("utf-8"))

threading.Thread(target=render_screen).start()



send_window = Tk()
send_box = Entry()
send_button = Button(text="Send",command=send)

send_box.pack()
send_button.pack()

但是在这里： 聊天= eval（s.recv（1024）.decode（“ utf-8”）） s.recv（1024） 返回[] [] [] [] [] [] [] [] ....

它只能返回一个列表。我该如何解决？

Python socket recv（）返回很多对象
