Socket.IO

问题 I have seen this question and answer, which explains how to share sessions with Socket.IO 1.x and Express 4.x and this blog which suggests the use of socketio-auth.

Does it add any security advantage? 回答1: If you already have an authenticated session via http in Express, then a socket.io connection is really JUST another http connection (it actually starts with an http connection and is

问题 I included the socket.io.js in client and also included the custom created socket.js for getting the responses from websocket server to client,when i loading this page in browser automatically stopped the websocket server and in browser console tells WebSocket connection to 'ws://localhost:8000/socket.io/?EIO=3&transport=websocket&sid=2p1ZYDAflHMHiL70AAAA' failed: Connection closed before receiving a handshake response user defined socket.js code is given below var socket = io(); var

问题 I am trying to learn how to use socket.io by building a simple chat app using the socket.io library and MEAN stack. From looking at some open source projects(like this one) I have seen that the client, mainly when executing the chat logic, communicates with the server via websockets and not the http client service provided by angular. Does this mean that when using web-sockets for real time updates there is no need to use http to communicate with the server? 回答1: Most assuredly not. It is not

问题 I have a node.js server (with socket.io) running using upstart and monit. My problem is my server becomes inaccessible (usually happens when im offline), and the monit is unable to restart the process. The server only reactivates or awakened if i login into the ftp using filezilla. This is my monit configuration: set logfile /var/log/monit.log check process mynode with pidfile /home/mylocation/pid/node-app.pid start program = "/etc/init.d/node-app start" uid nobody and gid nobody stop program
