Question

我的实现每次都会抛出一个错误（在chrome和safari中）。根据维基百科，它取决于他们提供的输入输出值here。

我不知道如何进一步调试这个，因为chrome和ff中的错误消息没有提供有关它们失败原因的信息（或者它们是什么？）

服务器 -

var domain = "http://www.mysitee.com/";
domain = "localhost/";
var port = 80;

var fs = require("fs");
var util = require("util");
var http = require("http");
var crypto = require("crypto");
var net = require("net");

var server = http.createServer();

var start = new Date().getTime();
var indexFile = fs.readFileSync(__dirname + "/index.htm");
var opened = new Date().getTime();

indexFile  = indexFile.toString() + "\
     <!-- read time: " + (opened - start) + "ms --><br/>\r\n\
    <!-- index size: " + (indexFile.length / 1024).toFixed(2) + "kb -->";

server.on("upgrade", function (req, socket, upgradeHead) {
    var crypto = require("crypto");
    var shasum = crypto.createHash("sha1");
    shasum.update(req.headers["sec-websocket-key"]);
    shasum.update("258EAFA5-E914-47DA-95CA-C5AB0DC85B11");
    var hash = shasum.digest("hex");
    console.log("hex:" + hash);
    var myVal = new Buffer(hash, "hex").toString('base64');
    console.log("myVal: " + myVal);
    socket.setNoDelay(true);
    socket.write("\
        HTTP/1.1 101 Switching Protocols\r\n\
        Upgrade: websocket\r\n\
        Connection: Upgrade\r\n\
        Sec-WebSocket-Accept: " + myVal + "\r\n\
        Sec-WebSocket-Protocol: chat\r\n\r\n"
    );
});
server.on("request", function (req, res) {
    if (req.url === "/e")
        process.exit();
    console.log("request " + indexFile.substring(0, 50));
    res.write(indexFile);
    res.end();
});
server.on("connection", function () {
    console.log("connection");
});
server.on("connect", function () {
    console.log("connect");
});
server.on("checkContinue", function () {
    console.log("check continue");
});
server.on("close", function () {
    console.log("close");
});
server.on("clientError", function (e) {
    console.log("client error");
 });
server.listen(port);

客户端 -

var connection = new WebSocket("ws:localhost:80");
connection.onopen = function () { alert("OPEN"); };
connection.message = function () { alert("MESSAGE"); };
connection.onerror = function (e) { alert("ERROR"); console.log(e); };
connection.onclose = function () { alert("CLOSE"); };

我无法让websockets在node.js中工作
