Question

我无法构建包含MD5哈希的S3预签名网址。以下是我使用的代码：

$s3 = new Aws\S3\S3Client( ... );
$md5Hash = "YmEwMWVmNzE5MjI3YzdjNmI0ZjYzNGMxZWI1MmY1Y2U=";
$cmd = $s3->getCommand('PutObject', [
                            'Bucket' => $bucket,
                            'Key'    => $key,
                            'Content-MD5' => $md5Hash,
                            'ContentType' => $contentType,
                            'Body'        => ''    
                        ]);

$request = $s3->createPresignedRequest($cmd, '+5 minutes');
$presignedUrl = (string)$request->getUri();

结果presignedURL看起来像：

http://s3-external-1.amazonaws.com/ {桶} / {键} X-AMZ-内容-SHA256 = UNSIGNED-PAYLOAD＆安培; X-AMZ-算法= AWS4-HMAC-SHA256＆安培; X-AMZ-凭证= AKIAIWC7FFD2T3NCEUNQ％2F20170503％ 2Fus - 东 - 1％2Fs3％2Faws4_request＆安培; X-AMZ-日期= 20170503T215723Z＆安培; X-AMZ-SignedHeaders =宿主安培; X-AMZ-过期= 3000＆安培; X-AMZ-签名= ca61d80dcfee351e7ee8440a47c5007f1bc905ddc8229077abddab9c39412dc7

当我将Content-MD5哈希添加到我的PUT请求时，我收到一个错误，表明MD5标题没有签名：

AccessDenied - 请求中存在未签名的标头 HeadersNotSigned - content-md5

任何帮助表示赞赏！

使用PHP SDK使用MD5哈希创建AWS S3预签名URL
