指定内容类型的AWS PHP的上传功能 [英] Specify Content-Type in AWS PHP's upload function

问题描述

我迁移我的code从AWS PHP SDK1到SDK2（的https：// github上.COM / AWS / AWS-SDK-PHP ）。

I am migrating my code from AWS PHP SDK1 to SDK2 (https://github.com/aws/aws-sdk-php).

我有一个图片上传。 在我的previous版本，我会指定的Content-Type我的形象的，像这样：

I have an image uploader. In my previous version, I would specify the Content-Type of my image like so:

$response = $this->s3->create_object(
                $bucket,
                $key,
                array(
                    'fileUpload'=>$file_resource,
                    'contentType'=>$mime, 
                    'acl' => AmazonS3::ACL_PUBLIC,
                    )
                );

这是我的新版本：

$response = $this->s3->upload(
                    $bucket, 
                    $key, 
                    $file_resource, 
                    'public-read',
                    array('params' => array('Metadata' => array('ContentType'=>$mime)))
                    );

我试过不同的拼法的ContentType，在S3网站将它修改为看起来像'X-AMZ-元的contentType的名字，而'的Content-Type的值为默认的'二元/ octet-流。

I've tried different spellings of ContentType, in the S3 site it modifies the name to look like 'x-amz-meta-contenttype', while the value of 'Content-Type' is the default 'binary/octet-stream'.

我也试着使用EntityBody功能，但同样的结果：

I've also tried using the EntityBody feature, but same results:

$response = $this->s3->upload(
                    $this->bucket, 
                    $to, 
                    EntityBody::factory($file_resource), 
                    'public-read',
                    array('params' => array('Metadata' => array('ContentType'=>$mime)))
                    );

我如何设置内容类型在这个新的API？

How do I set the content-type in this new API?

编辑：我看到某处的文件中：

I see somewhere in the documentation:

在AWS SDK的PHP将尝试自动确定最   用于存储对象​​适当的Content-Type头。如果你是   使用不常见的文件扩展名和您的Content-Type头不   自动添加的，你可以通过一个加Content-Type头   的ContentType选项到操作

The AWS SDK for PHP will attempt to automatically determine the most appropriate Content-Type header used to store the object. If you are using a less common file extension and your Content-Type header is not added automatically, you can add a Content-Type header by passing a ContentType option to the operation.

首先，我简单的上传图片，但根据我的S3的仪表板，它们被上传为二进制/八位字节流。关于他们的第二点，我试过阵列与ContentType的我不知道为什么它不工作的许多组合...

First off, I am uploading simple images, yet according to my S3 dashboard, they are uploaded as 'binary/octet-stream'. About their second point, I've tried many combinations of arrays with 'ContentType' I'm not sure why it's not working...

推荐答案

最后，这套方案的工作：

At the end, this set of options worked:

array('params' => array('ContentType' => $mime))

无需元
