websocket与http模块一起工作，但不能与express（node.js）
我正在尝试使用express和websocket模块使websokects与node.js一起工作。
有趣的是，如果我使用http模块创build服务器，他们按预期工作，我收到状态101。
但是，如果我使用快速模块来创build服务器，它会引发一个错误：
WebSocket connection to 'ws://localhost:2345/' failed: Error in connection establishment: net::ERR_CONNECTION_REFUSED 这是代码
// using http module (works) var WebSocketServer = require("websocket").server; var http = require("http"); var app = http.createServer(function(request, response) { response.writeHeader(200, {'Content-Type':'text/html'}); response.end(""+ "<!DOCTYPE html>"+ "<html>"+ "<head>"+ "<script>"+ "var ws = new WebSocket('ws://localhost:2345/');"+ "ws.onmessage = function(event) { "+ "var span = document.createElement('span');"+ "span.innerHTML = event.data;"+ "document.body.appendChild(span);"+ "}"+ "</script>"+ "</head>"+ "<body>"+ "<span>Messages: </span>"+ "</body>"+ "</html>" ); }); app.listen(2345); wsServer = new WebSocketServer({'httpServer':app}); wsServer.on("request", function(request) { var connection = request.accept(null, request.origin); console.log("Connection ACCEPTED\n"); connection.on("message", function(message) { if(message.type == 'utf8') { console.log("Received Message: %s", message.utf8Data); connection.sendUTF(message.utf8Data); } }) connection.on("close", function(reasonCode, description) { console.log("Connection lost\n"); }) })
和非工作部分
// using express module (get error) var WebSocketServer = require("websocket").server; var app = require('express')(); var app.get('/', function(request, response) { response.writeHeader(200, {'Content-Type':'text/html'}); response.end(""+ "<!DOCTYPE html>"+ "<html>"+ "<head>"+ "<script>"+ "var ws = new WebSocket('ws://localhost:2345/');"+ "ws.onmessage = function(event) { "+ "var span = document.createElement('span');"+ "span.innerHTML = event.data;"+ "document.body.appendChild(span);"+ "}"+ "</script>"+ "</head>"+ "<body>"+ "<span>Messages: </span>"+ "</body>"+ "</html>" ); }); app.listen(2345); wsServer = new WebSocketServer({'httpServer':app}); wsServer.on("request", function(request) { var connection = request.accept(null, request.origin); console.log("Connection ACCEPTED\n"); connection.on("message", function(message) { if(message.type == 'utf8') { console.log("Received Message: %s", message.utf8Data); connection.sendUTF(message.utf8Data); } }) connection.on("close", function(reasonCode, description) { console.log("Connection lost\n"); }) })
那里有什么可能是错的？ 如何解决这个问题？
Express中的app不是httpServer ，所以如果WebSocketServer没有明确地知道Express以及如何从中获取服务器，那么您可能需要给它实际的httpServer对象，而不是Express对象，您可以通过它改变这一点：
app.listen(2345); wsServer = new WebSocketServer({'httpServer':app});
对此：
var server = app.listen(2345); var wsServer = new WebSocketServer({'httpServer': server});
