在PHP的AWS SDK 的上传功能中指定Content-Type

今天准备将文件直接通过PHP临时文件夹上传到S3存储桶中,

遇到一个问题, 就是上传临时文件, 用fopen之后的ContentType 就变成八进制资源类型了,

查找资料找到修改类型的配置,

'params' => [
                'ContentType' => $mime,
            ],

详细参考代码如下:

<?php
namespace appapicontroller;

use AwsS3S3Client;
use AwsCredentialsCredentials;
use AwsExceptionMultipartUploadException;
use AwsS3MultipartUploader;
use thinkController;
use thinkLog;
use thinkRequest;

/**
 * thinkphp5 S3存储桶上传方法
 * 
 */
class Index extends Controller
{
    public function index()
    {
        $this->S3FileUploadTemp(
            Request::instance()->file('file')->getPathname(),
            '123.jpg',
            Request::instance()->file('file')->getInfo('type')
        );
    }

    /**
     * 加载s3客户端
     *
     * @return S3Client
     */
    public function AWS_S3Client(){

        //证书
        $credentials = new Credentials(
            'AWSAccessKeyId',
            'AWSSecretKey');

        //s3客户端
        return new S3Client([
            'version' => 'latest',
            //地区 亚太区域（新加坡）
            'region' => '存储桶的地区',//自行配置
            //加载证书
            'credentials' => $credentials,
            //开启bug调试
            //'debug'   => true
        ]);
    }

    /**
     * AWS S3上传文件
     * @param $file 上传文件
     * @param string $filename S3中的文件名,用户自定义
     * @param string $mime Content-Type
     *
     *
     * thinkphp5 中的用法
     *
     * $this->S3FileUploadTemp(
     *      Request::instance()->file('file')->getPathname(),
     *      '123.jpg',
     *      Request::instance()->file('file')->getInfo('type')
     *  );
     *
     *
     */
    public function S3FileUploadTemp($file, $filename = '',$mime='')
    {
        // Create an S3Client
        $s3Client = $this->AWS_S3Client();

        // 你的存储桶名称
        $bucket = 'your-bucket';

        // 待上传的文件路径或者对象资源
        $source = $file;
//        $source = '/path/to/large/file.zip';
//        $source = fopen($file, 'rb');

        $uploader = new MultipartUploader($s3Client, $source, [
            'bucket' => $bucket,
            'key' => $filename,
            'ACL' => 'public-read',
            'params' => [
                'ContentType' => $mime,
            ],
        ]);

        try {
            $result = $uploader->upload();

            // 返回上传后的地址
            $data = [
                'type' => '1',
                'message' => urldecode($result['ObjectURL'])
            ];
        } catch (MultipartUploadException $e) {
            Log::error($e->getMessage());

            $data = [
                'type' => '0',
                'message' => $e->getMessage()
            ];
        }

        dump($data);
//        return $data;
    }
}
