服务器端server.js代码
var express=require(“express”);
var http=require(“http”);
var sio=require(“socket.io”);
var app=express();
var server=http.createServer(app);
var fs=require(“fs”);
app.get(“/”, function (req,res) {
res.sendfile(__dirname+”/index.html”);
});
server.listen(1337);
var socket=sio.listen(server);
socket.on(“connection”, function (socket) {
socket.emit(“news”,{hello:”你好”});
socket.on(“otherEvent”, function (data) {
console.log(“服务器端接受到数据:%j”,data);
})
});
客户端index.html代码
<!DOCTYPE html>
<html>
<head lang=”en”>
<meta charset=”UTF-8″>
<title></title>
<script src=”/socket.io/socket.io.js”></script>
<script>
var socket=io.connect();
socket.on(“news”, function (data) {
console.log(data.hello);
socket.emit(“otherEvent”,{my:”data”});
});
</script>
</head>
<body>
</body>
</html>
忽然想到一个问题.我可不可以把news的监听代码写到和emit的同一端.
这样:
var express=require(“express”);
var http=require(“http”);
var sio=require(“socket.io”);
var app=express();
var server=http.createServer(app);
app.get(“/”, function (req,res) {
res.sendfile(__dirname+”/index.html”);
});
server.listen(1337,”127.0.0.1″, function () {
console.log(“开始监听1337”);
});
var socket=sio.listen(server);
socket.on(“connection”, function (socket) {
socket.on(“news”, function (data) {
console.log(data.hello);
});
socket.emit(“news”,{hello:”你好”});
});
