这简直要了我的命。我做了所有事情，但都不对，因为它仍然没有给我这个错误 Fatal error: Uncaught exception 'CFCredentials_Exception' with message 'No credentials were provided。我正在尝试使用 AWS sdk 1.6 示例和 jquery 文件上传插件将文件上传到 S3。我在wiki上找到了一个示例。
这是我的文件，我在其中设置awssdk.php了 wiki 示例中的凭据

  require_once 'sdk.class.php';
  require_once 'utilities.class.php';
  require_once 'credential.class.php';
  if (!class_exists('CFCredentials'))require_once('credentials.class.php');
  $name=null;
  CFCredentials::set(array(
    $name => array(
            'key' => 'access key',
            'secret' => 'secret key',
            'certificate_authority' => false
    ),
    '@default' => $name
    ));
  if (!class_exists('S3'))require_once('S3.php');
   $s3 = new AmazonS3();

我很确定我不应该需要这么多文件，但正如错误所暗示的那样，我必须添加依赖类。但我仍然收到上述错误。我还尝试包含config.class.php 凭据文件，但仍然出现此错误。
我在这方面花了很多时间，现在对这个 AWS sdk 有点失望。
我对 OO PHP 有点陌生，因此可能觉得它很困难。专家请提出一些解决方案来解决我的错误。

编辑：我相信这门课会导致问题，不知道怎么回事！！

似乎您正在遵循的任何教程都使这变得不必要地困难。尝试这个：

require_once 'sdk.class.php';

$s3 = new AmazonS3(array(
    'key'    => 'your_aws_access_key_id',
    'secret' => 'your_aws_secret_key',
));

您不需要任何其他文件。

You have set all Credential well but still you have leave one credential 'default_cache_config' => '' 
Just Put it in Credential array with some location for caching the default credential.
just have a look


$name=null;
     CFCredentials::set(array(
        $name => array(  

                'key' => 'access key',
                'secret' => 'secret key',
                 'default_cache_config' => '/home/user/any location',
                'certificate_authority' => false
        ),
        '@default' => $name
        ));**
