一、Socket套接字 网络上的两个程序通过一个双向的通信您连接实现数据交换,这个连接的一端称为一个socket。 java中使用socket完成TCP程序的开发,使用此类方法可以方便的建立可靠地,双向的,持续性的,点对点得通讯连接 在socket的程序开发中,服务器端使用ServerSocket等待客户端的连接,对于java的网络程序来说,每一个客户端都是用一个socket对象表示。 二、代码示例 2.1 完成一次服务端与客户端通信 用本机的当做服务器与客户端进行通信。 服务端等待客户端的连接,在客户端连接后发送数据给客户端。 Server package com.rrs.socketserver; import java.io.IOException; import java.io.OutputStream; import java.net.ServerSocket; import java.net.Socket; import org.junit.Test; /** * @author lzx * on 2019/9/25. */ public class SocketServer { @Test public void test01() throws IOException { System.out.println("socket server start...");

Python - BaseHTTPServer.HTTPServer Concurrency & Threading

喜你入骨 提交于 2019-11-30 11:55:48
Is there a way to make BaseHTTPServer.HTTPServer be multi-threaded like SocketServer.ThreadingTCPServer? Wolph You can simply use the threading mixin using both of those classes to make it multithread :) It won't help you much in performance though, but it's atleast multithreaded. from SocketServer import ThreadingMixIn from BaseHTTPServer import HTTPServer class MultiThreadedHTTPServer(ThreadingMixIn, HTTPServer): pass 来源: https://stackoverflow.com/questions/2398144/python-basehttpserver-httpserver-concurrency-threading

Shutdown socketserver serve_forever() in one-thread Python application

假装没事ソ 提交于 2019-11-30 11:21:15
I know that socketserver has a method shutdown() which causes server to shut down but this only works in multiple threads application since the shutdown needs to be called from different thread than the thread where serve_forever() is running. My application handles only one request at time so I don't use separate threads for handling requests and I am unable to call shutdown() because it causes deadlock (it's not in the docs but it's stated directly in the source code of socketserver). I'll paste here simplified version of my code for better understanding: import socketserver class

问题 How can I call shutdown() in a SocketServer after receiving a certain message "exit"? As I know, the call to serve_forever() will block the server. Thanks! 回答1: Use the source, Luke! Excerpt from SocketServer.py: def serve_forever(self, poll_interval=0.5): """Handle one request at a time until shutdown. Polls for shutdown every poll_interval seconds. Ignores self.timeout. If you need to do periodic tasks, do them in another thread. """ self.__is_shut_down.clear() try: while not self._

Python SocketServer: sending to multiple clients?

南楼画角 提交于 2019-11-27 21:35:12
Well, I'm trying to build a small python prgram with a SocketServer that is supposed to send messages it receives to all connected clients. I'm stuck, I don't know how to store clients on the serverside, and I don't know how to send to multiple clients. Oh and, my program fails everytime more then 1 client connects, and everytime a client sends more then one message... Here's my code until now: print str(self.client_address[0])+' connected.' def handle(self): new=1 for client in clients: if client==self.request: new=0 if new==1: clients.append(self.request) for client in clients: data=self

Adding SSL Support to SocketServer

问题 I have a Server based on ThreadingTCPServer . Now Ii want to add SSL Support to that Server. Without SSL it works fine but with SSLv3 I cant connect a Client to the Server, it always throws an exception: Error 111 Connection Refused . The error mens there's no SSL Server on that port. I added the SSL Support based on an example I found here at Stackoverflow. Here's my code: Server: class BeastServer(SocketServer.ThreadingMixIn, SocketServer.TCPServer): def __init__(self, server_address,
