chat_client.py

Question

我正在使用聊天客户端，这是我的代码：

import sys
import socket
import select


def run():

    host = "127.0.0.1"
    port = 8008
    buffer = 4096

    s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    s.settimeout(5)

    try:
        s.connect((host, port))
    except:
        print("Connection failed.")
        #exit

    print("Connected to " + host)
    sys.stdout.write('[Me] '); sys.stdout.flush()

    while True:
        sockets = [sys.stdin, s]
        ready_to_read, ready_to_write, in_error = select.select(sockets, [], [])

        for sock in ready_to_read:
            if sock == s:
                data = sock.recv(buffer)
                if not data:
                    print("Disconnected.")
                    #exit
                else:
                    sys.stdout.write(data)
                    sys.stdout.write('[Me] '); sys.stdout.flush()
            else:
                msg = sys.stdin.readline()
                s.send(msg)
                sys.stdout.write('[Me] '); sys.stdout.flush()


if __name__ == "__main__":
    sys.exit(run())

但是当我运行它时（服务器正在运行，请告诉我你是否需要代码）它给了我这个错误：

C:\Python34\python.exe C:/Dev/Python/Chat/Client/main.py
Traceback (most recent call last):
Connected to 127.0.0.1
  File "C:/Dev/Python/Chat/Client/main.py", line 44, in <module>
[Me]     sys.exit(run())
  File "C:/Dev/Python/Chat/Client/main.py", line 26, in run
    ready_to_read, ready_to_write, in_error = select.select(sockets, [], [])
OSError: [WinError 10038] An operation was attempted on something that is not a socket

Process finished with exit code 1

顺便说一下，我按照旧的Python 2教程来做这个（http://www.bogotobogo.com/python/python_network_programming_tcp_server_client_chat_server_chat_client_select.php）所以它可能与此有关。

我知道这已经过时了但它链接到的页面首先出现在我的搜索python聊天服务器中。由于我需要使用一些可用的代码，我认为其他人可能会喜欢更新的chat_client.py，以便与http://www.bogotobogo.com/python/python_network_programming_tcp_server_client_chat_server_chat_client_select.php

上非常简单的服务器一起使用

错误是因为sys.stdin不是Windows上的套接字。这降低了select的有用性，因此我们不得不使用线程。

这是Windows的最小正确客户端实现：

chat_client.py

import sys
import socket
import select
from threading import Thread

def receive(s):
    """Handles receiving of messages."""
    while True:
        try:
            ready = select.select([s], [], [])
            if ready[0]:
                data = s.recv(1024)
                if not data:
                    print '\nDisconnected from chat server'
                    sys.exit()
                else:
                    # print data
                    sys.stdout.write(data)
                    sys.stdout.write('[Me] ')
                    sys.stdout.flush()
        except OSError:  # Possibly client has left the chat.
            break


def chat_client2():
    if len(sys.argv) < 3:
        print 'Usage : python chat_client.py hostname port'
        sys.exit()

    host = sys.argv[1]
    port = int(sys.argv[2])

    s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    s.settimeout(2)

    # connect to remote host
    try:
        s.connect((host, port))
    except:
        print 'Unable to connect'
        sys.exit()

    print 'Connected to remote host. You can start sending messages'
    sys.stdout.write('[Me] ')
    sys.stdout.flush()

    receive_thread = Thread(target=receive, args=(s,))
    receive_thread.daemon = True
    receive_thread.start()

    while 1:
        # user entered a message
        msg = sys.stdin.readline()
        s.send(msg)
        sys.stdout.write('[Me] ')
        sys.stdout.flush()


if __name__ == "__main__":
    sys.exit(chat_client2())
