問題描述

好吧，我是 facebook sdk 的新手.我一直在遵循指南并按照所寫的步驟執行..但我收到此錯誤，我不知道為什么?

Well I am new to facebook sdk. I have being following the guideline and performing the steps as written.. but I am getting this error and I dont know why?

 Fatal error: Class 'FacebookFacebook' not found in C:wampwwwindex.php on line 134

錯誤行代碼為:

<?php 
$fb = new FacebookFacebook([
  'app_id' => '{app-id}',
  'app_secret' => '{app-secret}',
  'default_graph_version' => 'v2.2',
  ]);
?>

這不是我編造的，這與facebook指南中提到的代碼完全相同！我該怎么辦?

This is not something I have made up, this is exactly the same code mentioned in facebook guideline! What should I do?

推薦答案

您需要首先包含 autoloader 以訪問服務方法和類(如 Facebook API.您正在嘗試使用命名空間類 FacebookFacebook 來使用其方法，但 PHP 文件中沒有該類.

You need to include the autoloader first to get access to the service methods and classes (as said in the PHP SDK Documentation for Facebook API. You are trying to use a namespaced class FacebookFacebook, to use its methods, but you don't have the class in the PHP file.

require_once 'src/Facebook/autoload.php';
//Create the Facebook service
$fb = new FacebookFacebook ([
    'app_id' => '-----------------',
    'app_secret' => '--------------------',
    'default_graph_version' => 'v2.4'
    ]);

在您的目錄中的某處(如果您正確安裝了 Facebook PHP SDK)，您將找到 autoload.php 文件，該文件自動 requires 您需要的 .php 文件使用服務和方法.

Somewhere in your directory (if you installed the Facebook PHP SDK) correctly, you will find the autoload.php file which automatically requires .php files that you need to use the services and methods.
