当我在Node.js + Express中使用护照进行用户身份验证时会发生奇怪的事情

Question

In the beginning, I used this code to define LocalStrategy

    passport.use(
        'local-login',
        new LocalStrategy({
            usernameField:'username',
            passwordField: 'password',
            passReqtoCallback: true
        },
            function(req,username,password,done){
            ....

Then, the passport couldn't work well.It read password as username and couldn't read username from the HTML form.

I was so confused and then I downloaded other people's source code and applied it to my code. In fact, I only changed above part to this:

 passport.use(
  'local-login',
  new LocalStrategy({
   usernameField: 'username',
   passwordField: 'password',
   passReqToCallback: true
  },
 function(req,username,password,done){
            ....

And it just worked!!!!

Actually, I think those two codes are only different in indentation.So what is my original mistake?Could anyone tell me, thanks!

(To make it more clear , I upload the screenshot from my IDE)

This is buggy Code.

This is the code that works well.

Answer 1

In your original code you have

passport.use(
  'local-login',
  new LocalStrategy({
    ...
    passReqtoCallback: true // misspelled!
  }),
  ...
)

instead of

passport.use(
  'local-login',
  new LocalStrategy({
    ...
    passReqToCallback: true
  }),
  ...
)
