我有两个客户端可以通过 socket.io 交换一些数据。我也有一个服务器。我需要做的是我想通过套接字将数据从客户端 1 发送到客户端 2，但我无法弄清楚如何实现它。请注意，客户端 1 和客户端 2 是不同的 html 页面。
Server.JS
var express = require('express');
var app = express();
var fs = require('fs');
var path = require('path');
var server = require('http').createServer(app);
var io = require('socket.io')(server);
var port = process.env.PORT || 3000;
var ip=process.env.IP||"192.168.1.5";
app.use(express.static(__dirname));
server.listen(port,ip, function () {
console.log('Server listening at port %d ', port);
});
app.get('/index', function(req, res) {
res.sendFile(path.join(__dirname,'/test.html'));
})
app.get('/index1', function(req, res) {
res.sendFile(path.join(__dirname,'/test1.html'));
})
io.on('connection', function (socket) {
socket.on('broadcast', function (message) {
console.log(message);
socket.broadcast.emit('message', message);
});
console.log("connected");
});
Client1.JS
<!doctype html>
<html lang="en">
<head>
</head>
<body>
<script src="/socket.io/socket.io.js"></script>
<script >
var socket = io.connect();
socket.emit('broadcast',"Broadcasting Message");
socket.on('message', function (data) {
alert(data)
});
</script>
</body>
Client2.JS
<!doctype html>
<html lang="en">
<head>
</head>
<body>
<script src="/socket.io/socket.io.js"></script>
<script >
var socket = io.connect();
socket.on('message', function (data) {
alert(data)
//socket.emit('message',"Hello world");
});
</script>
</body>
最佳答案
好的，这是我在本地所做的，您可以根据需要进行更改。
server.js
var io = require('socket.io')(80);
io.on('connection', function (socket) {
socket.on('broadcast', function (message) {
console.log(message);
socket.broadcast.emit('message', message);
});
console.log("connected");
});
client1.js
var socket = io.connect('ws://127.0.0.1');
socket.emit('broadcast',"Broadcasting Message");
socket.on('message', function (data) {
$('#client1').html(data);
});
client2.js
var socket = io.connect('ws://127.0.0.1');
socket.on('message', function (data) {
$('#client2').html(data);
});
index.html
<!DOCTYPE html>
<html>
<head>
<title></title>
<script type="text/javascript" src='https://code.jquery.com/jquery-1.12.4.min.js'></script>
<script type="text/javascript" src="/socket.io/socket.io.js"></script>
<script type="text/javascript" src="client1.js"></script>
<script type="text/javascript" src="client2.js"></script>
</head>
<body>
<div> <h1> CLIENT 1 </h1><div id="client1"></div></div>
<div> <h1> CLIENT 2 </h1><div id="client2"></div></div>
</body>
</html>
在终端上运行node server.js并重新加载页面后，您将看到client2将附加广播消息 html
