Facebook API从今天出现错误

问题描述

直到今天，我的Facebook api在PHP下工作得很好。
我没有改变任何东西。但从今天起，我收到以下错误：

有人有一个想法，我如何解决这个错误？

解决方案

这是因为。

此后脆弱性今天宣布，许多服务暂时关闭了SSLv3，包括Facebook，Facebook Facebook在其PHP SDK中使用SSLv3。

我不知道您有与我相同的Facebook PHP SDK版本，但如果您有base_facebook.php文件，请找到以下行：

  $选择[CURLOPT_SSLVERSION] = 3; 
  

并将其更改为一个值t不允许SSLv3（）：

  $ opts [CURLOPT_SSLVERSION] = CURL_SSLVERSION_DEFAULT; 
  

或：

 code> $ opts [CURLOPT_SSLVERSION] = CURL_SSLVERSION_TLSv1; 
  

或：

 code> $ opts [CURLOPT_SSLVERSION] = CURL_SSLVERSION_TLSv1_0; 
  

这样Facebook API调用将使用TLSv1.0而不是SSLv3。
在我的情况下，这一行在第963行的makeRequest（$ url，$ params，$ ch = null）函数中，但是根据您使用的PHP SDK的版本可能会有所不同。 / p>

till today my facebook api under PHP worked well.I did not change anything. But from today on i get the following error:

Has anybody got an idea, how i could solve that error?

解决方案

It's because of the POODLE: SSLv3.0 vulnerability (CVE-2014-3566).

After this vulnerability was announced today, many services disabled SSLv3 completely for the time being, including Facebook, and it happens that Facebook uses SSLv3 in their PHP SDK.

I am not sure if you have the same Facebook PHP SDK version as me, but if you have the base_facebook.php file, find the line:

$opts[CURLOPT_SSLVERSION] = 3;

And change it to a value that does not allow SSLv3 any longer (find all constants listed):

$opts[CURLOPT_SSLVERSION] = CURL_SSLVERSION_DEFAULT;

or:

$opts[CURLOPT_SSLVERSION] = CURL_SSLVERSION_TLSv1;

or:

$opts[CURLOPT_SSLVERSION] = CURL_SSLVERSION_TLSv1_0;

This way the Facebook API calls will use TLSv1.0 instead of SSLv3.In my case this line is in the "makeRequest($url, $params, $ch=null)" function at line 963, but depending on the version of the PHP SDK you're using it may differ.
