[英]Passport.js not calling LocalStrategy if fields are empty
I'm having a problem where if I try to login with no username or password my passport.use
function isn't being called at all. 我在哪里,如果我尝试没有用户名或密码我登录的问题
passport.use
功能不会被调用的。
Below is my express post route that runs passport.authenticate
. 以下是我的运行
passport.authenticate
特快专递路线。
app.post('/login', passport.authenticate('local-login', {
failureRedirect: '/login', // redirect back to the login page if there is an error
failureFlash: true // allow flash messages
})
And below is my passport.use
that should print GOT HERE
whenever there is a post request to /login
. 下面是我的
passport.use
,当有/login
的发帖请求时,应该在GOT HERE
打印GOT HERE
。
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
// 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
console.log("GOT HERE");
This works fine if email
and password
have some type of value. 如果
email
和password
具有某种类型的值,则此方法很好用。 But I would like this function to be called even if there is no value for email
and password
so that I can do custom error handling. 但是,即使
email
和password
没有值,我也希望调用此函数,以便我可以执行自定义错误处理。
How can I achieve this? 我该如何实现?
You could add middleware befure authentication strategy being called. 您可以添加称为中间件身份验证策略的中间件。 Something like this:
像这样:
app.post('/login', function(req, res, next) {
// do custom error handling
}, passport.authenticate('local-login', {
failureRedirect: '/login', // redirect back to the login page if there is an error
failureFlash: true // allow flash messages
})
And in this middleware you could do some custom error handling 在此中间件中,您可以执行一些自定义错误处理
