php - Using Laravel Socialite to connect facebook and validating user permissions -

currently creating website allow user login facebook. , website require email.

the problem how facebook authorization require email. when user doesn't give email permission, how cancel authorization process.

i know facebook docs tell me, facebook not guarantee grab user email. how cancel when user not allow email in permission list

email

provides access person's primary email address via email property on user object.

do not spam users. use of email must comply both facebook policies , can-spam act.

note, if request email permission not guaranteed email address. example, if signed facebook phone number instead of email address, email field may empty.

review app may use permission without review facebook.
