我最初使用此Websocket/node tutorial作为起点。这是我的第一次尝试，所以当我开始时几乎什么都不知道。
＆＃34;连接关闭......握手＆＃34;这是一个非常普遍的问题，似乎没有明确的答案。从许多SO问题我花了一天时间尝试答案和建议代码，没有效果，包括检查我的代理和允许localhost（没有快乐）。
这是我的代码，包括一个（不完整的）前端（我在我的本地目录中使用npm install websocket，而不是使用socket.io，虽然我愿意尝试我＆＃ 39; d宁愿让这个先工作一下）：
"use strict";
let http = require('http');
let fs = require('fs');
let server = http.createServer(function(request, response) {});
const PORT=8080;
fs.readFile('client/index.html', function (err, html) {
if (err) throw err;
http.createServer(function(request, response) {
response.writeHeader(200, {"Content-Type": "text/html"});
response.write(html);
response.end();
console.log(`${(new Date())} Server is listening on port ${PORT}`);
}).listen(PORT);
});
let WebSocketServer = require('websocket').server;
let wsServer = new WebSocketServer({
httpServer: server
});
wsServer.on('request', function(r){
// runs on connection
let connection = r.accept('echo-protocol', r.origin);
let count = 0;
let clients = {};
// Specific id for this client & increment count
let id = count++;
// Stores the connection method for looping through & contacting all clients
clients[id] = connection;
console.log(`${(new Date())} Connection accepted [${id}]`);
connection.on('message', function(message) {
// The string message sent to us
let msgString = message.utf8Data;
// Loops through all clients
for(let i in clients){
// Sends a message to the client with the message
clients[i].sendUTF(msgString);
}
});
connection.on('close', function(reasonCode, description) {
delete clients[id];
console.log(`${(new Date())} Peer ${connection.remoteAddress} disconnected.`);
});
});
