AWS S3 node.js SDK上传的文件和文件夹权限

问题描述

我正在使用aws-sdk软件包将文件上传到S3:

I'm uploading file to S3 using aws-sdk package:

fs.readFile(sourceFile, function (err, data) {
    if (err) { throw err; }

    s3.client.putObject({
        Bucket: bucketName,
        Key: 'Folder/image.jpg',
        Body: data
    }, function (res) {
            console.log('Successfully uploaded file.');
        })

});

我需要使上传的文件可以通过cloudfront下载，如果我确定正确的话，我需要设置文件权限:每个人都可以打开/下载，Folder2应该公开(通过菜单公开").所以有两个问题:

I I need to make uploaded file to be downloadable via cloudfront, if I asume right, I need to set permissions on file: Everyone Open/Download, Folder2 should be made public (via menu Make Public). So 2 questions:

1)如何设置\修改上载文件的权限\文件夹?

1) How to set\modify permissions on uploaded file\folder?

2)如何使用适用于node.js的AWS开发工具包公开文件夹.

2) How make Folder public using AWS SDK for node.js.

推荐答案

找到了 http://docs.aws.amazon.com/AmazonS3/latest/dev/ACLOverview. html#CannedACL

需要在putObject中添加选项:

need to add option in putObject:

ACL:'public-read'
