Sending Data Continuously from Python to Javascript over Websockets?

由 强颜欢笑 提交于 2021-01-01 13:38:21
问题 Hello I'm currently running code that sends data from Python to JavaScript. Currently, because I'm not able to send data straight from the primary code I'm running, I am communicating between UDP Connections across two separate Python Files: I merged UDP Server Code with the Main Code I'm running which is an OpenCV Eye Coordinate Tracker. This UDP Server carries the Eye Coordinate data and sends it to the UDP Client which I have merged with the Websocket Server that is communicating with a

netty 与 webSocket 起因 有个需求需要用到 webSocket ，然后最近又正好在学 netty ，然后合起来走一波。写篇文章记录一下，做一个念想。 协议格式 0 1 2 3 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 +-+-+-+-+-------+-+-------------+-------------------------------+ |F|R|R|R| opcode|M| Payload len | Extended payload length | |I|S|S|S| (4) |A| (7) | (16/64) | |N|V|V|V| |S| | (if payload len==126/127) | | |1|2|3| |K| | | +-+-+-+-+-------+-+-------------+ - - - - - - - - - - - - - - - + | Extended payload length continued, if payload len == 127 | + - - - - - - - - - - - - - - - +-------------------------------+ | |Masking-key, if MASK

《菜鸟教程》| Egret搭建WebSocket简易聊天室

由 ☆樱花仙子☆ 提交于 2020-12-31 11:04:12
本文，我们通过Egret和Node.js实现一个在线聊天室的demo。主要包括，聊天，改用户名，查看其他用户在线状态的功能。大致流程为，用户访问网页，即进入聊天状态，成为新游客，通过底部的输入框，可以输入自己想说的话，点击发布，信息呈现给所有在聊天的人的页面。用户可以实时修改自己的昵称，用户离线上线都会实时广播给其他用户。 体验链接 http://7hds.com:8888/ 下图为最终制作完成的聊天面板 WebSocket服务器可以用其他语言编写，本文采用的方法建立在Node.js上 。 在Node.js中我们使用ws第三方模块来实现服务器业务逻辑的快速搭建，还需使用uuid模块生成随机id，你需要使用npm包管理器来安装ws、uuid模块。使用以下命令： npm install ws -g npm install uuid -g 安装完成之后，使用终端工具进入服务器目录，开始编写代码： // 引入ws模块 var WebSocket = require('ws' ); // 创建websocket服务，端口port为：**** var WebSocketServer = WebSocket.Server, wss = new WebSocketServer({port: 8180 }); // 引入uuid模块 var uuid = require('node-uuid' );

How to access an insecure websocket from a secure website?

由 元气小坏坏 提交于 2020-12-31 06:25:26
问题 TL;DR: A website is served over HTTPS and needs to access a WebSockets server over an unencrypted channel (ws:// url). The browser doesn't like this. Encrypting the websocket is possible, but inconvenient - there is no trusted authority which could sign the certificate and thus it will be needed to manually install it for every client. I'd like to leave that as the last resort. The website must be served over HTTPS and cannot be downgraded to HTTP. Is there any other way to bypass this

Getting socket.io, express & node-http2 to communicate though HTTP/2

由 随声附和 提交于 2020-12-31 06:08:34
问题 I wrote a Web Socket server using socket.io, node-http2 and express in Node.js. The server works as intended, except for the fact that according to Chrome's DevTools socket.io's negotiation requests go through HTTP/1.1 (shown below). The "Protocol" column should be displaying h2 if the request was sent using HTTP/2. This only happens in Chrome, other browsers use the correct protocol. The server code (shortened): var PORT = 8667, config = require('./config'), socketioServer = require('socket
