Node.js 节点SocketIo-客户端不发射？
我遇到节点SocketIo客户端不发送数据的问题。因此，当客户机在index.html中连接时，会记录“已连接，这是一个测试”，但它不会socket.emit（'cool'），不会出现错误，也不会登录server.js。我不知道为什么它没有发出或者服务器没有监听 Server.jsNode.js 节点SocketIo-客户端不发射？,node.js,socket.io,Node.js,Socket.io,我遇到节点SocketIo客户端不发送数据的问题。因此，当客户机在index.html中连接时，会记录“已连接，这是一个测试”，但它不会socket.emit（'cool'），不会出现错误，也不会登录server.js。我不知道为什么它没有发出或者服务器没有监听 Server.js const path = require('path'); const http = require('http'); const express = require('express'); const socket

此外，您确实不应该发出系统使用的事件名称，如

io.on('connection', () => {
console.log('New WS connection...');
io.emit('connection', 'This Is A Test');
});
io.on('cool', (msg) => {

// send a test event back to the socket that just connected
socket.emit('test', 'This Is A Test');
// listen for the cool message on this new socket
socket.on('cool', (msg) => {
