But not able the fetch birthday.

回答1:

You can't fetch users birthdate only yours you can get and you have to send app in review for approve in facebook developer after than if your app approve than you can set extra permissions but i don't think that users birthday you can get.

Try the account in which you have registered your app. Don't try with other Facebook account.

It will give you a Birhtday.

Also check privacy settings of account.

Birthday may not be public. That can also be an issue.

Thanks

回答5:

Take in account that to get the birthday (and some other attributes like the user bio) the app has to be reviewed by Facebook. Otherwise, although the permissions were given correctly to the user the Graph API call will not retrieve this attribute.
