所以,我现在已经在这几个小时内一直在努力。当我使用AJAX向服务器发送内容时,会话不会被发送到服务器,但是没有AJAX就可以正常工作,比如点击链接,注销等等,这让我沮丧地拉扯我的头发。无论如何,这些是我的代码:
var express = require('express'), // express 4
mongoskin = require('mongoskin'),
Busboy = require('busboy'),
cookieParser = require('cookie-parser'),
session = require('express-session'),
mailer = require('nodemailer'),
compress = require('compression'),
morgan = require('morgan'),
ect = require('ect'),
suspend = require('suspend'),
MongoStore = require('connect-mongo')(session);
app.use(compress());
app.engine('.ect', renderer.render);
app.set('env', 'development');
app.use(express.static(__dirname + '/public'));
app.use(cookieParser());
app.use('/admin', session({
secret : 'qlauwork secret yo',
name : 'qlauworks.sess',
proxy : true,
rolling : true,
cookie : {
maxAge : 1000 * 60 * 60 * 6
},
store : new MongoStore({
db : 'qlauworks',
auto_reconnect : true,
defaultExpirationTime : 1000 * 60 * 60 * 6
}),
unset : 'destroy'
}));
// ... etc etc
app.post('/admin/login', function (req, res) {
var msg = {};
var busboy = new Busboy({ headers : req.headers });
busboy.on('field', function (fieldName, val) {
msg[fieldName] = val;
});
busboy.on('finish', function () {
suspend.run(function * () {
msg.password = crypto.createHash('whirlpool').update(SALT).update(msg.password).digest('hex');
var user = yield db.users.findOne({ username : msg.username, password : msg.password }, suspend.resume());
if (!user) {
return res.json({ error : 'Wrong username or password' });
}
// create session token
var token = yield crypto.randomBytes(32, suspend.resume());
token = token.toString('hex');
yield db.users.update({ username : msg.username }, { $set : { token : token } }, { upsert : true }, suspend.resume());
req.session.token = token;
res.redirect('/admin/forms');
}, function (err) {
if (err) {
console.log('login: ', err);
res.send('Server error');
}
});
});
req.pipe(busboy);
});
// this is the logout and forms, works just fine
app.get('/admin/logout', auth, function (req, res) {
suspend.run(function * () {
var token = req.session.token;
yield db.users.update({ token : token }, { $unset : { token : true } }, suspend.resume());
delete req.session.token;
req.session.destroy(function (err) {
if (!err) {
res.clearCookie('qlauworks.sess', { path : '/' });
res.redirect('/admin');
}
});
}, function (err) {
if (err) {
console.log('logout: ', err);
res.json({ error : 'Server error' });
}
});
});
app.get('/admin/forms', auth, function (req, res) {
res.send(formPage);
});
// and this is the auth middleware, could logout and moving around the admin page
// but req.session always undefined if comes from an AJAX request
function auth (req, res, next) {
suspend.run(function * () {
console.log(req.session);
console.log('=====================================================')
if (!req.session.token) {
return res.json({ error : 'Invalid token' });
}
var user = yield db.users.findOne({ token : req.session.token }, suspend.resume());
if (!user.username) {
return res.json({ error : 'Invalid token' });
}
next();
}, function (err) {
if (err) {
console.log('auth: ', err);
res.json({ error : 'Server error' });
}
});
}
这是客户端
$.post('/api/item/new', elem, function (rep) {
thisForm.find('input[type="submit"]').attr('disabled', false);
if (rep.error) {
$('#alert-multi').removeClass('success').addClass('alert').text(rep.error);
} else {
$('#alert-multi').removeClass('alert').addClass('success').text('Success');
$('input[type="reset"]').click();
for (var i = 0; i < len; i++) {
$('#preview-multi' + i).attr('src', '');
$('#multi' + i).attr('data-image-src', '');
}
}
});
那么,我该如何解决这个问题?
答案 0 :(得分:0)
您似乎已在/admin
上安装了会话中间件,但您正在尝试呼叫/api/item/view
。
使用express.use(path, middleware)
的工作不会仅对middleware
包含req.url
的请求调用path
。
在/
上安装会话中间件(不使用path
参数 - 简单express.use(middleware)
会这样做),或者将您的ajax网址更改为以/admin
开头(可能不是你想做的事。)
