问题描述

好吧，我是 facebook sdk 的新手.我一直在遵循指南并按照所写的步骤执行..但我收到此错误，我不知道为什么?

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

错误行代码为:

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

这不是我编造的，这与facebook指南中提到的代码完全相同！我该怎么办?

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

推荐答案

您需要首先包含 autoloader 以访问服务方法和类(如 Facebook API.您正在尝试使用命名空间类 FacebookFacebook 来使用其方法，但 PHP 文件中没有该类.

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'
    ]);

在您的目录中的某处(如果您正确安装了 Facebook PHP SDK)，您将找到 autoload.php 文件，该文件自动 requires 您需要的 .php 文件使用服务和方法.

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.
