Question

试图为整个套接字连接以及所有连接到该套接字的客户端发出事件。

io.sockets.emit('toALL',{msg: 'this is demo'});

并使用以下代码行在index.html中进行处理：

socket.on("toALL",function(){
   // If console is putted here still not able to get any msg or response from emit. 
});

Answer 1

您发送到套接字的对象可用作let isValidPassword = function (password) { if (password.length <= 8 && password.includes('password')) { console.log('Password is not according to Company Policy.'); } else { console.log('Password is accepatble!'); } } isValidPassword();的回调函数的参数。您可以使用.on广播给所有客户端。

io.emit

// server
io.emit("toALL", {msg: "this is demo"});

Answer 2

我从以下位置获得了解决方案：https://socket.io/get-started/chat#Integrating-Socket-IO

对于 server.js：

io.on('connection', function(socket){
   socket.on('toALL', function(msg){
     io.emit('toALL', msg);
   });
 });

对于Client.html

socket.emit('toALL', 'event');
    socket.on('toALL', function(msg){
      alert(msg);
    });

事件发射不起作用io.sockets.emit（）
