Node.js를 처음 접했고 몇 가지 문제가 있습니다.
Node.js 4.10 및 Express 2.4.3을 사용하고 있습니다.
내가 접근하려고 할 때 http://127.0.0.1:8888/auth/facebook , 내가로 연결됩니다 http://127.0.0.1:8888/auth/facebook_callback .
그런 다음 다음 오류가 발생했습니다.

다음은 내 코드입니다.
var fbId= "XXX";
var fbSecret= "XXXXXX";
var fbCallbackAddress= "http://127.0.0.1:8888/auth/facebook_callback"
var cookieSecret = "node"; // enter a random hash for security
var express= require('express');
var auth = require('connect-auth')
var app = express.createServer();
app.configure(function(){
app.use(express.bodyParser());
app.use(express.methodOverride());
app.use(express.cookieParser());
app.use(express.session({secret: cookieSecret}));
app.use(auth([
auth.Facebook({
appId : fbId,
appSecret: fbSecret,
callback: fbCallbackAddress,
scope: 'offline_access,email,user_about_me,user_activities,manage_pages,publish_stream',
failedUri: '/noauth'
})
]));
app.use(app.router);
});
app.get('/auth/facebook', function(req, res) {
req.authenticate("facebook", function(error, authenticated) {
if (authenticated) {
res.redirect("/great");
console.log("ok cool.");
console.log(res['req']['session']);
}
});
});
app.get('/noauth', function(req, res) {
console.log('Authentication Failed');
res.send('Authentication Failed');
});
app.get('/great', function( req, res) {
res.send('Supercoolstuff');
});
app.listen(8888);
내 코드에 어떤 문제가 있는지 알 수 있습니까?
