只能说界面丑陋忽略它。
server.js:
var ws = require("nodejs-websocket"); console.log("开始建立连接..."); var str1 = null, str2 = null, clientReady = false, serverReady = false; var a = []; var server = ws.createServer(function (conn) { conn.on('text', function (str) { a.push(str); if (!clientReady) { if (a[0] === str) { str1 = conn; clientReady = true; str1.sendText("欢迎你" + str); } } else if (!serverReady) { if (str.indexOf('close') >= 0) { a.splice(2, 1); clientReady = false; str1 = null; return; } if (a[1] === str) { str2 = conn; serverReady = true; str2.sendText("欢迎你" + str); str1.sendText(str + "在线啦，你们可以聊天啦"); return; } } else if (clientReady && serverReady) { str2.sendText(str); str1.sendText(str); if (str.indexOf('close') >= 0) { a.splice(2, a.length); var len = a.length; for (var i = 0; i < len; i++) { // 定位该元素位置 if (str.indexOf(a[i]) >= 0) { a.splice(i, 1); if (i == 0) { str1 = str2; } serverReady = false; str2 = null; return; } } } } }) conn.on("close", function (code, reason) { console.log("关闭连接"); clientReady = false; serverReady = false; }) conn.on("error", function (code, reason) { console.log("异常关闭"); }); }).listen(8082); console.log("websocket连接完毕")
简单的截图说明一下：
开启服务，相同页面执行两遍，就可以聊天啦。反正过程就是这样。就是还有一个大的问题。比如我a断开连接了，只有b一个人在连接巨人b还能发信息，可以发信息算可以吧。居然b自己接收自己的信息。那就不能忍了。
就是这种呀，逻辑都错乱了，理清逻辑是个费脑子的事情。有知道的同学吗？怎么处理呀
