套接字.IO web客户端不工作

socket.io web client not working

本文关键字：工作 客户端 web IO 套接字      更新时间：2023-09-26

我最近遇到了socket世界。IO和node.js我在网上找到了这个服务器示例:https://gist.github.com/creationix/707146我在iOS上创建了第一个客户端，我接收和调度消息，与telnet客户端相同，接下来我想创建第二个客户端与套接字。IO也可以在浏览器上接收消息

我尝试了howto: http://socket.io/#how-to-use中的示例，但这些示例甚至无法识别客户端!

我错在哪里?我从哪里开始呢?

服务器代码:

// Load the TCP Library
net = require('net');
// Keep track of the chat clients
var clients = [];
// Start a TCP Server
net.createServer(function (socket) {
// Identify this client
socket.name = socket.remoteAddress + ":" + socket.remotePort 
// Put this new client in the list
clients.push(socket);
// Send a nice welcome message and announce
socket.write("Welcome " + socket.name + "'n");
broadcast(socket.name + " joined the chat'n", socket);
// Handle incoming messages from clients.
socket.on('data', function (data) {
broadcast(socket.name + "> " + data, socket);
});
// Remove the client from the list when it leaves
socket.on('end', function () {
clients.splice(clients.indexOf(socket), 1);
broadcast(socket.name + " left the chat.'n");
});
// Send a message to all clients
function broadcast(message, sender) {
clients.forEach(function (client) {
  // Don't want to send it to sender
  if (client === sender) return;
  client.write(message);
});
// Log it to the server output too
process.stdout.write(message)
}
}).listen(5000);
// Put a friendly message on the terminal of the server.
console.log("Chat server running at port 5000'n");

客户端代码:

<script src="/socket.io/socket.io.js"></script>
<script>
var socket = io.connect('http://localhost');
socket.on('news', function (data) {
console.log(data);
socket.emit('my other event', { my: 'data' });
 });
</script>

我知道已经晚了，您可能已经解决了这个问题，但是服务器正在侦听端口5000。您的客户端正在连接到80端口。

修改客户端代码为:

   <script src="/socket.io/socket.io.js"></script>
   <script>
   var socket = io.connect('http://localhost:5000');
   socket.on('news', function (data) {
   console.log(data);
   socket.emit('my other event', { my: 'data' });
    });
   </script>
