python监听2个端口相同的文件

发布于 2024-08-18 10:45:46 字数 178 浏览 7 评论 0原文

我想用同一台服务器监听 2 个不同的 UDP 端口。我的服务器使用 SocketServer lib，基本上它看起来像这样；

SocketServer.UDPServer(('', 7878),CLASSNAME)

我想用相同的服务器和相同的文件监听 7878 和 7879。这可能吗？如果是的话怎么办？

当然可以，使用线程。这是一个服务器：

import SocketServer
import threading


class MyUDPHandler(SocketServer.BaseRequestHandler):
    def handle(self):
        data = self.request[0].strip()
        socket = self.request[1]
        print "%s wrote:" % self.client_address[0]
        print data
        socket.sendto(data.upper(), self.client_address)


def serve_thread(host, port):
    server = SocketServer.UDPServer((host, port), MyUDPHandler)
    server.serve_forever()


threading.Thread(target=serve_thread,args=('localhost', 9999)).start()
threading.Thread(target=serve_thread,args=('localhost', 12345)).start()

它创建一个服务器来监听 9999，另一个服务器监听 12345。
下面是一个可用于测试此功能的示例客户端：

import socket
import sys

HOST, PORT = "localhost", 12345
data = 'da bomb'

# SOCK_DGRAM is the socket type to use for UDP sockets
sock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)

# As you can see, there is no connect() call; UDP has no connections.
# Instead, data is directly sent to the recipient via sendto().
sock.sendto(data + "\n", (HOST, PORT))
received = sock.recv(1024)

print "Sent:     %s" % data
print "Received: %s" % received

注意：这取自 SocketServer 模块的文档，并使用线程进行了修改。

Sure you can, using threads. Here's a server:

import SocketServer
import threading


class MyUDPHandler(SocketServer.BaseRequestHandler):
    def handle(self):
        data = self.request[0].strip()
        socket = self.request[1]
        print "%s wrote:" % self.client_address[0]
        print data
        socket.sendto(data.upper(), self.client_address)


def serve_thread(host, port):
    server = SocketServer.UDPServer((host, port), MyUDPHandler)
    server.serve_forever()


threading.Thread(target=serve_thread,args=('localhost', 9999)).start()
threading.Thread(target=serve_thread,args=('localhost', 12345)).start()

It creates a server to listen on 9999 and another to listen on 12345.
Here's a sample client you can use for testing this:

import socket
import sys

HOST, PORT = "localhost", 12345
data = 'da bomb'

# SOCK_DGRAM is the socket type to use for UDP sockets
sock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)

# As you can see, there is no connect() call; UDP has no connections.
# Instead, data is directly sent to the recipient via sendto().
sock.sendto(data + "\n", (HOST, PORT))
received = sock.recv(1024)

print "Sent:     %s" % data
print "Received: %s" % received

Note: this was taken from the docs of the SocketServer module, and modified with threads.
