亚马逊网络服务S3 cURL超时

Question

总的来说，亚马逊网络服务S3在我的网站上运行得很好。然而，在下载时，我总是随机地得到这些错误：

Error retrieving credentials from the instance profile metadata server. (cURL error 28: Operation timed out after {>1000} milliseconds with 0 bytes received (see http://curl.haxx.se/libcurl/c/libcurl-errors.html))

为什么？如何防止这些错误发生？

我使用的是AWS SDK PHP v3。

Answer 1

如果您使用的凭据如下所示

$s3 = new Aws\S3\S3Client([
        'version' => 'latest',
        'region'  => 'us-east-1',
        'key' => "AKIAJAAAXXYASASASASDSUAG66MA",
        'secret'  => "8sZyAAAAXUSuUK3FJSDFSDS&D*SDSJFSFShjssa7Fx+GS9"
    )
]);

然后改成这样

   $s3 = new Aws\S3\S3Client([
        'version' => 'latest',
        'region'  => 'us-east-1',
        'credentials' => array(
            'key' => "AKIAJAAAXXYASASASASDSUAG66MA",
            'secret'  => "8sZyAAAAXUSuUK3FJSDFSDS&D*SDSJFSFShjssa7Fx+GS9"
        )
    ]);
