使用Passport.SocketIO cookie解析器错误

Question

我使用以下内容:

"dependencies": {
    "express": "^4.0.0",
    "socket.io": "0.9.16",
    "mongoose": "^3.8.8",
    "passport": "^0.2.0",
    "passport-local": "^1.0.0",
    "express-session": "^1.0.3",
    "cookie-parser": "^1.0.1",
    "body-parser": "^1.0.2",
    "session-mongoose": "git://github.com/danpe/session-mongoose.git#master",
    "passport.socketio": "^3.0.1"
  }

设置我的socket.io授权:

io.set("authorization", passportSocketIo.authorize({
    passport : passport,
    cookieParser: cookieParser(),
    key:    settings.sessionKey,  //the cookie where express (or connect) stores its session id.
    secret: settings.sessionSecret,       //the session secret to parse the cookie
    store:  sessionStore,  //the session store that express uses
    fail: function(data, accept) {
        console.log("failed");
        // console.log(data);// *optional* callbacks on success or fail
        accept(null, false);             // second param takes boolean on whether or not to allow handshake
    },
    success: function(data, accept) {
        console.log("success socket.io auth");
        // console.log(data);
        accept(null, true);
    }
}));

当我尝试与我的客户连接时:

var socket = io.connect('http://127.0.0.1:3000/');
socket.on('connect', function () {
    // socket connected
    console.log("Socket Connected!");
});

服务器崩溃时出现以下情况:

S:\Server\node_modules\cookie-parser\index.js:27
    var cookies = req.headers.cookie;
                             ^

    at HTTPParser.parserOnHeadersComplete [as onHeadersComplete] (http.js:121:23)

任何想法如何发生这种情况？

这是一个愚蠢的错误,我应该将cookieParser作为库而不是实例化对象传递:

var cookieParser= require('cookie-parser');

io.set("authorization", passportSocketIo.authorize({
    passport : passport,
    cookieParser: cookieParser,
    key:    settings.sessionKey,  //the cookie where express (or connect) stores its session id.
    secret: settings.sessionSecret,       //the session secret to parse the cookie
    store:  sessionStore,  //the session store that express uses
    fail: function(data, accept) {
        console.log("failed");
        // console.log(data);// *optional* callbacks on success or fail
        accept(null, false);             // second param takes boolean on whether or not to allow handshake
    },
    success: function(data, accept) {
        console.log("success socket.io auth");
        // console.log(data);
        accept(null, true);
    }
}));
