使用Facebook PHP SDK。我跟着一個教程之後,跑進一個問題,得到這個頁面加載,這將是錯誤,我得到:
下面是代碼(應用程序ID和祕密密鑰已被刪除) 。我從教程中獲得了該文件,並從GitHub上提供的文件中填入了一些內容。
<?php
require 'src/facebook.php'
$app_id = ""; // has been removed
$secret = ""; // has been removed
$app_url = "http://apps.facebook.com/instahomework/";
// Create our Application instance (replace this with your appId and secret).
$facebook = new Facebook(array(
'appId' => $app_id,
'secret' => $secret,
));
// Get User ID
$user = $facebook->getUser();
// We may or may not have this data based on whether the user is logged in.
//
// If we have a $user id here, it means we know the user is logged into
// Facebook, but we don't know if the access token is valid. An access
// token is invalid if the user logged out of Facebook.
if ($user) {
try {
// Proceed knowing you have a logged in user who's authenticated.
$user_profile = $facebook->api('/me');
} catch (FacebookApiException $e) {
error_log($e);
$user = null;
}
}
// Login or logout url will be needed depending on current user state.
if ($user) {
$logoutUrl = $facebook->getLogoutUrl();
} else {
$loginUrl = $facebook->getLoginUrl();
// This call will always work since we are fetching public data.
$naitik = $facebook->api('/naitik');
?>

添加了''之後}自動顯示這些類型的錯誤' $ loginUrl = $ facebook-> getLoginUrl();'終止'else'。 – DCoder
