亚马逊s3 - 图像下载而不是在浏览器中显示

This is driving me mad. I am uploading images to S3 using the php SDK. Whenever I browse to the image URL, the browser downloads the image opposed to displaying it.

这让我很生气。我正在使用php SDK将图像上传到S3。每当我浏览图像URL时，浏览器都会下载与显示图像相反的图像。

I think its something to do with content type.

我认为它与内容类型有关。

        // Prepare to upload the file to S3 bucket.
        $s3->create_object($bucket, $file_name, array(
                'contentType' => 'binary/octet-stream',
                'acl' => AmazonS3::ACL_PUBLIC
        ));

Can you help?

你能帮我吗？

#1

            $s3->create_object($bucket, $file_name, array(
                    'fileUpload' => $resized_image,
                    'contentType' => $_FILES['image']['type'],
                    'acl' => AmazonS3::ACL_PUBLIC
            ));

Your content type is wrong indeed. It needs to be image/jpeg for JPGs, for instance. See this site for a list: http://en.wikipedia.org/wiki/Internet_media_type

您的内容类型确实是错误的。例如，它需要是JPG的image / jpeg。请访问此站点以获取列表：http：//en.wikipedia.org/wiki/Internet_media_type

Working on your own, seemingly valid, assumption that it is the content type:

依靠自己，看似有效，假设它是内容类型：

You need to set the correct content type for the image being upload, the following list contains all the most common types

您需要为要上载的图像设置正确的内容类型，以下列表包含所有最常见的类型

* image/gif: GIF image
* image/jpeg: JPEG JFIF image
* image/png: Portable Network Graphics
* image/svg+xml: SVG vector image
* image/tiff: Tag Image File Format
* image/vnd.microsoft.icon: ICO image

So a rework of your sample code for a png upload:

因此，为png上传重新编写示例代码：

// Prepare to upload the file to S3 bucket.
$s3->create_object($bucket, $file_name, array(
            'contentType' => 'image/png',
            'acl' => AmazonS3::ACL_PUBLIC
));

If you are working URL images use

如果您正在使用URL图像

'ContentType'  => mime_content_type($absolutePathToImage),

instead of

代替

$_FILES['image']['type']

            $s3->create_object($bucket, $file_name, array(
                    'fileUpload' => $resized_image,
                    'contentType' => $_FILES['image']['type'],
                    'acl' => AmazonS3::ACL_PUBLIC
            ));
