如何更新AWS S3文件权限？ [英] How update AWS S3 file permission?

问题描述

我使用node.js使用Multipart Upload将视频上传到Amazon-S3我正在使用此 [ ^ ]参考



默认情况下上传的视频只能由所有者访问。



使用以下代码上传文件时

Hi,

I uploading videos using Multipart Upload to Amazon-S3 using the node.js. I am using the this[^] reference

The uploaded video by default is only accessible to owner.

When uploading file using below code

var params_to_upload_on_S3 = {
                    ACL: 'public-read',
                    Bucket: imageBucket,
                    Key: imgName  + ".jpg",
                    Body: imageBuffer,
                    ContentType : 'Image/jpg'
                }

            s3.putObject(params_to_upload_on_S3 , function (err, res) {
                if(err)
                    console.log('Thumnail Upload Error'+ err);
                else 
                    console.log('Thumbnail Successfully uploaded .'+ JSON.stringify(res));

                fs.unlink(imagePath, function(){
                    console.log('File deleted from local storage');
                });

            });

putObject有一个选项ACL：'public-read'来设置允许。但是我在MultipartUpload中找不到任何选项。



有没有更新现有文件权限的选项，还是可以在分段上传中设置权限？

"putObject" has a option ACL: 'public-read' to set the permission. but i didn't find any option in MultipartUpload.

Is there any option to update the permission of existing file or can set permission in Multipart Upload?

推荐答案

您好，

在上面的链接中，您可以使用第四个选项上传带有元数据的文件。在元数据下，您可以更改文件的权限。
