Eri*_*ron 4 node.js express passport.js
按照示例https://scotch.io/tutorials/easy-node-authentication-setup-and-local我创建了一个简单的注册应用程序来测试护照。
我正在使用 Express 4 和连接闪存模块。
我的路线如下,即在GET /signup我显示带有任何可能的signupMessage闪存消息(始终未定义)的注册表单上。在POST /signup我尝试验证凭据时:
router.get('/signup', function(req, res) {
debug('GET signup flash message "%s"',req.flash('signupMessage'));
res.render('signup', { message: req.flash('signupMessage') });
});
// process the signup form
router.post('/signup', passport.authenticate('local-signup', {
successRedirect : '/profile', // redirect to the secure profile section
failureRedirect : '/signup', // redirect back to the signup page if there is an error
failureFlash : true // allow flash messages
}));

接下来是我的护照相关代码。它有效,但return done(null, false, req.flash('signupMessage', 'That email is already taken.'));似乎必须设置请求 flash 消息之类的行似乎不起作用,因为 flash 消息从未显示在 GET 方法显示的注册表单中。
passport.use('local-signup', new LocalStrategy({
// by default, local strategy uses username and password, we will override with email
usernameField : 'email',
passwordField : 'password',
passReqToCallback : true // allows us to pass back the entire request to the callback
},
function(req, email, password, done) {
debug("Auth");
// asynchronous
// User.findOne wont fire unless data is sent back
process.nextTick(function() {
debug("before findOne");
// find a user whose email is the same as the forms email
// we are checking to see if the user trying to login already exists
User.findOne({ 'local.email' : email }, function(err, user) {
debug("inside findOne");
// if there are any errors, return the error
if (err) {
return done(err);
}
// check to see if theres already a user with that email
if (user) {
debug('user exists');
return done(null, false, req.flash('signupMessage', 'That email is already taken.'));
} else {
debug('creating new user');
// if there is no user with that email
// create the user
var newUser = new User();
// set the user's local credentials
newUser.local.email = email;
newUser.local.password = newUser.generateHash(password);
// save the user
newUser.save(function(err) {
if (err) {
throw err;
}
return done(null, newUser);
});
}
});
});
}));

在寻求帮助后,我也尝试输入:
return done(null, false, {message: 'That email is already taken.'});

并在GET /signup方法中使用:
router.get('/signup', function(req, res) {
res.render('signup', { message: req.flash('error') });
});

但这不起作用。
任何人都可以帮助我吗?
谢谢。
对于任何可能遇到类似问题的人,我发现我的错误在于会话配置。
如文档所示,如果您设置了安全 cookie 选项,则您的连接必须通过 HTTPS 进行,否则将不会创建 cookie。这就是正常消息和闪现消息都不起作用的原因。
