我正在开发 AWS EC2 Ubuntu计算机并尝试从 AWS S3 获取图片,但每次都向我显示以下错误。
<Error>
<Code>InvalidArgument</Code>
<Message>
Requests specifying Server Side Encryption with AWS KMS managed keys require AWS Signature Version 4.

这是我的存储桶政策

"Resource": "arn:aws:s3:::mytest.sample/*"
}
]
}
以下是代码
require 'aws-autoloader.php';
$credentials = new Aws\Credentials\Credentials('key', 'key');
$bucketName = "mytest.sample";
$s3 = new Aws\S3\S3Client([
'signature' => 'v4',
'version' => 'latest',
'region' => 'ap-southeast-1',
'credentials' => $credentials,
'http' => [
'verify' => '/home/ubuntu/cacert.pem'
],
'Statement' => [
'Action ' => "*",
],
]);
$result = $s3->getObject(array(
'Bucket' => $bucketName,
'Key' => 'about_us.jpg',
));
HTML
<img src="<?php echo $result['@metadata']['effectiveUri']; ?>" />
迈克尔的编辑 - sqlbot:这里我使用默认的KMS。
try {
$result = $this->Amazon->S3->putObject(array(
'Bucket' => 'mytest.sample',
'ACL' => 'authenticated-read',
'Key' => $newfilename,
'ServerSideEncryption' => 'aws:kms',
'SourceFile' => $filepath,
'ContentType' => mime_content_type($filepath),
'debug' => [
'logfn' => function ($msg) {
echo $msg . "\n";
},
'stream_size' => 0,
'scrub_auth' => true,
'http' => true,
],
));
} catch (S3Exception $e) {
echo $e->getMessage() . "\n";
}

PHP sdk v2
Aws\Common\Credentials
S3Client
您需要工厂尝试这样的事情
use Aws\S3\S3Client;
use Aws\Common\Credentials\Credentials;
$credentials = new Credentials('YOUR_ACCESS_KEY', 'YOUR_SECRET_KEY');
// Instantiate the S3 client with your AWS credentials
$s3Client = S3Client::factory(array(
'signature' => 'v4',
'region' => 'ap-southeast-1',
'credentials' => $credentials,
.....
]);
)
如果这不起作用,您可能会尝试明确声明SignatureV4
对象
use Aws\S3\S3Client;
use Aws\Common\Credentials\Credentials;
use Aws\Common\Signature\SignatureV4;
$credentials = new Credentials('YOUR_ACCESS_KEY', 'YOUR_SECRET_KEY');
// Instantiate the S3 client with your AWS credentials
$s3Client = S3Client::factory(array(
'signature' => new SignatureV4(),
'region' => 'ap-southeast-1',
'credentials' => $credentials,
.....
]);
)
如果您升级到sdk v3
signature_version
(而不是signature
)作为参数Statement
似乎不是有效参数(http://docs.aws.amazon.com/aws-sdk-php/v3/guide/guide/configuration.html#signature-version)debug
参数以获得更多输出这看起来像这样
$s3 = new Aws\S3\S3Client([
'signature_version' => 'v4',
'version' => 'latest',
'region' => 'ap-southeast-1',
'credentials' => $credentials,
'http' => [
'verify' => '/home/ubuntu/cacert.pem'
],
'debug' => true
]);

我还使用aws:kms
encyrption密钥来解决此问题,我建议如果您想使用kms
密钥,则必须在kms key
中创建IAM section of AWS Console
。我喜欢推荐AES256
服务器端加密,这里S3在获取对象时自动加密和解密数据。请通过以下链接:
S3 Server Side encryption with AES256
我的解决方案是更改此行'ServerSideEncryption' => 'aws:kms' with 'ServerSideEncryption' => 'AES256'
try {
$result = $this->Amazon->S3->putObject(array(
'Bucket' => 'mytest.sample',
'ACL' => 'authenticated-read',
'Key' => $newfilename,
'ServerSideEncryption' => 'AES256',
'SourceFile' => $filepath,
'ContentType' => mime_content_type($filepath),
'debug' => [
'logfn' => function ($msg) {
echo $msg . "\n";
},
'stream_size' => 0,
'scrub_auth' => true,
'http' => true,
],
));
} catch (S3Exception $e) {
echo $e->getMessage() . "\n";
}
请同时使用以下json更新您的存储分区政策,这会阻止您上传没有AES256
加密的对象

"Sid": "DenyUnEncryptedObjectUploads",
"Effect": "Deny",
"Principal": "*",
"Action": "s3:PutObject",
"Resource": "arn:aws:s3:::yourbucketname/*",
