在S3上上傳文件的MIME類型

如何在Amazon S3上更改上傳文件的MIME類型。我嘗試過http://docs.amazonwebservices.com/AWSSDKforPHP/latest/#m=AmazonS3/change_content_type但它不起作用。在S3上上傳文件的MIME類型

你得到的錯誤/信息是什麼？ –

isOK顯示爲真，但不是真實的。 – Dev

請發佈您的代碼 – mfonda

你可以試試這個：

// Instantiate the class 
$s3 = new AmazonS3(); 

$bucket_name = 'my-bucket'; 
$file_name = 'test1.txt'; 
$mime_type = getMimeType($file_name); 

$response = $s3->change_content_type($bucket_name, $file_name, $mime_type); 

// Success? 
var_dump($response->isOK()); 

function getMimeType($file) { 
    // MIME types array 
    $mimeTypes = array(

感謝，因爲它的幫助，但「change_content_type」不適合我。 – Dev

核心亞馬遜S3服務沒有嘗試複製就地（即替換）操作過程中保留ACL或內容類型。

我知道AmazonS3 :: change_content_type（）方法只是copy_object（）方法的一個包裝。如果您使用look at the implementation，您將看到在執行就地複製操作以解決核心S3服務中的此問題之前，PHP SDK嘗試查找當前的ACL和內容類型。

如果它不適合你，你有沒有發佈這個錯誤AWS PHP forum？看起來，SDK的開發人員對解決那裏報告的錯誤非常敏感。
