【问题描述】:
我没有登录页面,而是在每个页面上都有一个登录表单。无论身份验证是否成功(使用适当的闪存消息),我都想将用户重定向回他们所在的同一页面
取以下代码:
app.post('/login', validateLogin, passport.authenticate('local-login'), function(req, res) {
var redirectUrl = '/';
if(req.body.to.length > 0){
redirectUrl = req.body.to;
}
console.log("THIS IS ONLY CALLED IF passport.authenticate() IS SUCCESSFUL");
res.redirect(redirectUrl);
});
如果通过了身份验证,我只会看到上面的最终中间件被调用。如果失败,则护照似乎以获取请求的形式将我重定向到 /login。在我的应用中,此页面不存在。
如果我在护照身份验证函数中传递一个额外的选项对象作为参数,那么这可以工作:
app.post('/login', validateLogin, passport.authenticate('local-login', {
successRedirect : '/', // redirect to the secure profile section
failureRedirect : '/signup', // redirect back to the signup page. THIS IS JUST FOR TESTING TO SEE IF THE REDIRECT ON FAIL WORKS.
failureFlash : true, // allow flash messages
}
));
但是这样做我失去了选择将用户重定向到哪里的能力。如果身份验证失败,护照似乎可以控制用户被重定向到的位置。我怎样才能解决这个问题?或者它是一个错误?如果身份验证失败,护照身份验证必须是链中的最后一个中间件吗?
这是我的本地策略函数调用:
//LOCAL LOGIN
passport.use('local-login', 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) { // callback with email and password from our form
console.log("IN PASSPORT");
if(email.length == 0 || password.length == 0){
console.log("FIELDS ARE EMPTY");
return done(null, false, req.flash('loginMessage', 'Fill in all values.'));
}
// 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) {
// if there are any errors, return the error before anything else
if (err){
return done(err);
console.log("db err");
}
// if no user is found, return the message
if (!user){
console.log("not user");
return done(null, false, req.flash('loginMessage', 'Incorrect details.')); // req.flash is the way to set flashdata using connect-flash
}
// if the user is found but the password is wrong
if (!user.validPassword(password)){
console.log("invalid pw");
return done(null, false, req.flash('loginMessage', 'Incorrect details.')); // create the loginMessage and save it to session as flashdata
}
// all is well, return successful user
console.log("All OK");
return done(null, user);
});
}));
