Amazon S3 PHP SDK：上载的图像具有错误的mime类型

Question

I tried the following two functions, none of them works, they could upload the file to S3 but if you visit the uploaded file from a browser you could see it's being treated as application/octet-stream, that's not right...

$s3->upload('mybucket', // bucket
    $filename, // key
    $imagebinarydata, // body
    'public-read', // acl
    array('contentType' => 'image/jpeg')); // options

And

$s3->putObject(array(
    'Bucket'        => 'mybucket',
    'Key'           => $filename,
    'ACL'           => 'public-read',
    'contentType'   => 'image/jpeg',
    'Body'          => $imagebinarydata));

I'm using the latest AWS.PHAR

您需要按照docs中所述将大写ContentType与putObject一起使用：

'ContentType' => 'image/jpeg'
