答案为否，请查看此处的文档https://developers.facebook.com/docs/authentication/signed_request/

你得到这样的数据

Array ( 
  [algorithm] => HMAC-SHA256 
  [issued_at] => 1328803958 
  [page] => Array ( 
    [id] => 114951721840 
    [liked] => 1 
    [admin] => 1 ) 
    [user] => Array ( 
      [country] => us 
      [locale] => en_US 
      [age] => Array ( [min] => 21 ) 
    ) 
)
