build a websocket application". The preceding Code introduces the parseCookie used to parse the cookie, so the session is parsed through the cookie. First, we need to process the header file after setting up the socket listener and parse the session in the cookie. For example, the following code: Var io = sio. listen (app); // sets sessionio. set ('authorization

This article mainly introduces node. use socket in js. io method. For more information, see use socket. use io to create a socket. i/O server. however, this server depends on a created http server. After the http server is running, use the listen method to append a

have not studied it carefully. I understand callback quickly and I will first use the callback function for processing. The last is the most critical communication phase. The background code of the socket. io module is as follows: Var io = require ('socket. io '). listen

step will go to github to download npm files and progress, and the fourth step is to install npm to node. js will copy several cmd files and the mode_modules folder to the nodejs directory. In this way, npm is configured. If you need to install any modules, enter npm install ***.

Building the simplest EventBus javascript library is not difficult: Yongboy = {}; Yongboy. eventbus = {Listeners :{List :{},Add: function (event, fn ){This. list [event] = fn;},Remove: function (event ){This. list [event] = null;}}, Subscribe: function (event, fn ){This. listeners. add (event, fn );}, // Simulate the event interface of socket. io clientOn: function (event, fn ){This. subscribe

becomes more difficult and the versatility, availability, and flexibility must be taken into account. Taking a general asynchronous Windows Socket TCP Server Component Based on IOCP as an example, this article describes its design and implementation problems, hoping to stimulate everyone's thinking, it will be helpful for you to carry out similar work in the future. The topic about universality, availabili
