if (!isset($this->fb))
{
require_once 'facebook-php-sdk/autoload.php';
$this->fb = new FB([
'app_id'=> $this->config->item('facebook_app_id'),
'app_secret'=> $this->config->item('facebook_app_secret'),
'default_graph_version' => $this->config->item('facebook_graph_version')
]);
}
at the top of file i added line 在文件顶部,我添加了一行
use Facebook\Facebook as FB;
At the top of the file you have not required Facebook API yet. 在文件顶部,您还不需要Facebook API。
Try to move require_onde
to the top also 尝试将
require_onde
也移到顶部
require_once 'facebook-php-sdk/autoload.php';
use Facebook\Facebook as FB;
I get the same error with the latest version of HybridAuth (2.8): 最新版本的HybridAuth(2.8)出现相同的错误:
FastCGI sent in stderr: "PHP message: PHP Fatal error: Class 'Facebook\\Facebook' not found in "/var/www/connect/lib/vendor/hybridauth/hybridauth/hybridauth/Hybrid/Providers/Facebook.php" on line 56" while reading response header from upstream
在stderr中发送的FastCGI:“ PHP消息:PHP致命错误:在” /var/www/connect/lib/vendor/hybridauth/hybridauth/hybridauth/Hybrid/Providers/Facebook.php”中找不到类'Facebook \\ Facebook'从上游读取响应标头时为56英寸
I installed HybridAuth via composer, so I also get the new facebook sdk. 我通过composer安装了HybridAuth,因此我也得到了新的facebook sdk。 Is the new facebook sdk (5.4.1) stable?
新的Facebook SDK(5.4.1)是否稳定? Or is it included correctly?
还是正确包含? Because the error seems to be a namespace's error.
因为该错误似乎是名称空间的错误。
I fixed with a downgrade a 2.7 version of hybridauth, with the older sdk. 我使用旧版SDK降级了HybridAuth 2.7版本。
