javascript範例：
//判斷是否登入中
function checkLoginState() {
FB.getLoginStatus(function(response) {

});
}
// 判斷登入狀態
function statusChangeCallback3(response) {
console.log('statusChangeCallback');
// The response object is returned with a status field that lets the
// app know the current login status of the person.
// Full docs on the response object can be found in the documentation
// for FB.getLoginStatus().
if (response.status === 'connected') {
// Logged into your app and Facebook.
api_me(response);
// console.log(response);
} else if (response.status === 'not_authorized') {
// The person is logged into Facebook, but not your app.
console.log('not_authorized');
// document.getElementById('status').innerHTML = 'Please log ' + 'into this app.';

// The person is not logged into Facebook, so we're not sure if
// they are logged into this app or not.
console.log('else');
// document.getElementById('status').innerHTML = 'Please log ' + 'into Facebook.';
}
}
// 登入中取得資訊後，像後端傳送資料
