如何用python socketserver.TCPServer制作多客戶端聊天室

Question

我必須使用 Python 中的 serversocket 模塊提供的 TCPServer 創建一個多客戶端聊天室。我如何將它變成一個多客戶端服務器並將消息發送到所有其他客戶端？

我嘗試修改示例中的現有代碼

...python

import socket
import threading
import socketserver

clientList = []
class ThreadedTCPRequestHandler(socketserver.BaseRequestHandler):

    def handle(self):
        clientList.append(self.client_address)
        print(clientList)
        print("Client List Length : ",len(clientList))

        while True:
            data = str(self.request.recv(1024), 'ascii')
            if(data.upper() == "EXIT"):
                break
            cur_thread = threading.current_thread()
            response = bytes(data, 'utf_8')
            #self.request.sendall(response)

            for cl in range(1,len(clientList)):
                print("sending to : ",clientList[cl])
                self.request.sendto(response,clientList[cl])

class ThreadedTCPServer(socketserver.ThreadingMixIn, socketserver.TCPServer):
    pass

def passtime():
    pass
if __name__ == "__main__":

    HOST, PORT = "localhost", 50007


server = ThreadedTCPServer((HOST, PORT), ThreadedTCPRequestHandler)
ip, port = server.server_address



# Start a thread with the server -- that thread will then start one
# more thread for each request
server_thread = threading.Thread(target=server.serve_forever)

# Exit the server thread when the main thread terminates
server_thread.daemon = True
server_thread.start()
while server_thread:
   passtime() 
print("Server loop running in thread:", server_thread.name)

...

我有一個問題： self.request.sendto(request,clientList[cl])

僅將請求發送回發送客戶端，而不是客戶端列表中的目標客戶端。

編輯：我找到了一個解決方案，這是它：

import socket
import threading
import socketserver
import sys
import select

clientList = []
inbox = []


class ThreadedTCPRequestHandler(socketserver.BaseRequestHandler):
    clients = []    
    msgSend = 0
    def setup(self):
        clientList.append(self.client_address)
        self.clients = list(dict.fromkeys(clientList))
        print(self.clients)
        print("Client List Length : ",len(self.clients))

    def handle(self):
        while True:
            r,w,e = select.select([self.request],[],[],0.01)
            for rs in r:
                if rs == self.request:
                    data = str(self.request.recv(1024),"ascii")
                    if data:
                        inbox.append(data)
                else:
                    if self.msgSend < len(inbox):
                        for elem in range(self.msgSend, len(inbox)):
                            print("server send :",inbox[elem])
                            self.request.sendall(bytes(inbox[elem],'utf-8'))
                        self.msgSend += 1

            if self.msgSend < len(inbox):
                for elem in range(self.msgSend, len(inbox)):
                    print("server send :",inbox[elem])
                    self.request.sendall(bytes(inbox[elem],'utf-8'))
                self.msgSend += 1

    def finish(self):
        for l in range(len(clientList)):
            if self.client_address == clientList[l]:
                clientList.remove(l)

class ThreadedTCPServer(socketserver.ThreadingMixIn, socketserver.TCPServer):
    pass

def passtime():
    pass



if __name__ == "__main__":

    HOST, PORT = "localhost", 50007
    server = ThreadedTCPServer((HOST, PORT), ThreadedTCPRequestHandler)
    ip, port = server.server_address

    server_thread = threading.Thread(target=server.serve_forever)


    server_thread.daemon = True
    server_thread.start()
    while server_thread:
       passtime() 


    sys.exit()

我從這里使用收件箱方法並使用select.select我能夠檢查是否有要讀取的輸入。

您可以使用PySock ，這是一個 python 庫，它使編寫多客戶端服務器變得極其容易。 您可以從 PyPi 下載它，對於 windows： pip install PySock和對於 Linux： pip3 install PySock 。 他們在 PyPi 介紹頁面上有非常好的樣板代碼。 您可以在此處查看或 go 至GitHub存儲庫以獲取有關版本的更多信息。

我找到了一個解決方案，就是這樣：

import socket
import threading
import socketserver
import sys
import select

clientList = []
inbox = []


class ThreadedTCPRequestHandler(socketserver.BaseRequestHandler):
    clients = []    
    msgSend = 0
    def setup(self):
        clientList.append(self.client_address)
        self.clients = list(dict.fromkeys(clientList))
        print(self.clients)
        print("Client List Length : ",len(self.clients))

    def handle(self):
        while True:
            r,w,e = select.select([self.request],[],[],0.01)
            for rs in r:
                if rs == self.request:
                    data = str(self.request.recv(1024),"ascii")
                    if data:
                        inbox.append(data)
                else:
                    if self.msgSend < len(inbox):
                        for elem in range(self.msgSend, len(inbox)):
                            print("server send :",inbox[elem])
                            self.request.sendall(bytes(inbox[elem],'utf-8'))
                        self.msgSend += 1

            if self.msgSend < len(inbox):
                for elem in range(self.msgSend, len(inbox)):
                    print("server send :",inbox[elem])
                    self.request.sendall(bytes(inbox[elem],'utf-8'))
                self.msgSend += 1

    def finish(self):
        for l in range(len(clientList)):
            if self.client_address == clientList[l]:
                clientList.remove(l)

class ThreadedTCPServer(socketserver.ThreadingMixIn, socketserver.TCPServer):
    pass

def passtime():
    pass



if __name__ == "__main__":

    HOST, PORT = "localhost", 50007
    server = ThreadedTCPServer((HOST, PORT), ThreadedTCPRequestHandler)
    ip, port = server.server_address

    server_thread = threading.Thread(target=server.serve_forever)


    server_thread.daemon = True
    server_thread.start()
    while server_thread:
       passtime() 


    sys.exit()

我從這里使用inbox方法並使用select.select我能夠檢查是否有要讀取的輸入。
