使用AWS presignedURL的PUT文件

Question

我正在用aws-sdk-php创建预先签名的URL,用于将文件上传到S3存储桶.GET的URL正在运行.

这是代码

$client = S3Client::factory(array('region' => 'eu-west-1','key' => 'xxx','secret' => 'xxx',));

//option 1
$command = $client->getCommand('PutObject', array(
    'Bucket' => 'myBucket',
    'Key' => 'testing/signedPHP1_'.time(),
    'ContentType' => 'image/jpeg',
    'Body' => 'dump' //it's mandatory
));
$signedUrl = $command->createPresignedUrl('+5 minutes');
$signedUrl .= '&Content-Type=image%2Fjpeg';
echo("\n\nThe URL is: ". $signedUrl . "\n");
echo("Now run from console for upload:\ncurl -v -H \"Content-Type: image/jpeg\" -T /tmp/temp.jpg '" . $signedUrl . "'");

//option 2
$request = $client->put('myBucket/testing/signedPHP2_'.time());
$signedUrl = $client->createPresignedUrl($request, '+5 minutes');
$signedUrl .= '&Content-Type=image%2Fjpeg';
echo("\n\nThe URL is: ". $signedUrl . "\n");
echo("Now run from console for upload:\ncurl -v -H \"Content-Type: image/jpeg\" -T /tmp/temp.jpg '" . $signedUrl . "'");

//GET which works
$request = $client->get('myBucket/testing/existingFile.txt');
$signedUrl = $client->createPresignedUrl($request, '+5 minutes');
echo("\n\nThe URL is: ". $signedUrl . "\n");
echo("Now run:\ncurl '" . $signedUrl . "'");

//GET which works
$command = $client->getCommand('GetObject', array('Bucket' => 'myBucket','Key' => 'upload/data.txt'));
$signedUrl = $command->createPresignedUrl('+5 minutes');
echo("\n\nThe URL is: ". $signedUrl . "\n");
echo("Now run:\ncurl '" . $signedUrl . "'");

当我尝试使用curl命令时,我收到并错误 SignatureDoesNotMatch with message 我们计算的请求签名与您提供的签名不匹配.检查您的密钥和签名方法.

用于Javascript的aws-sdk中的类似代码正在运行

var AWS = require('aws-sdk');
AWS.config.update({ accessKeyId: 'xxx', secretAccessKey: 'xxx', region: 'eu-west-1' });
var s3 = new AWS.S3();
var params = {
    Bucket: 'myBucket',
    Key: 'testing/preSignedURLnodeJS_' + (+new Date),
    ContentType: 'image/jpeg',
    Expires: 60 * 5
};
s3.getSignedUrl('putObject', params, function(err, url) {
    console.log('The URL is: ', url);
    console.log('Now run from console for upload:\n\ncurl -v -H "Content-Type: image/jpeg" -T /tmp/temp.jpg \'' + url + '\'');
});

已经做了很多研究但没有结果.我究竟做错了什么？

在Github上我得到了SDK开发人员的回答,它说

$command = $client->getCommand('PutObject', array(
    'Bucket' => 'myBucket',
    'Key' => 'testing/signedPHP1_'.time(),
    'ContentType' => 'image/jpeg',
    'Body'        => '',
    'ContentMD5'  => false
));
