AWS S3 node.js SDK uploaded file and folder permissions
提问by WHITECOLOR
I'm uploading file to S3 using aws-sdk package:
我正在使用 aws-sdk 包将文件上传到 S3：
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.');
})
});
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:
II需要使上传的文件可以通过cloudfront下载，如果我认为正确，我需要设置文件权限：Everyone Open/Download，Folder2应该公开（通过菜单Make Public）。所以2个问题：
1) How to set\modify permissions on uploaded file\folder?
1) 如何设置\修改上传文件\文件夹的权限？
2) How make Folder public using AWS SDK for node.js.
2) 如何使用适用于 node.js 的 AWS 开发工具包公开文件夹。

Here is a working code snippet that uploads a local file (test-file.gif) to S3 bucket and prints out a URL for everyone to download.
这是一个工作代码片段，它将本地文件 (test-file.gif) 上传到 S3 存储桶并打印出一个 URL 供所有人下载。
const fs = require('fs');
const AWS = require('aws-sdk');
AWS.config.update({ region: 'us-west-1' });
// Fill in your bucket name and local file name:
const BUCKET_NAME = 'test-bucket-name-goes-here'
const FILE_NAME_LOCAL = './test-file.gif'
const FILE_NAME_S3 = 'this-will-be-the-file-name-on-s3.gif'
const FILE_PERMISSION = 'public-read'
// Create S3 service object
s3 = new AWS.S3({ apiVersion: '2006-03-01' });
// Get file stream
const fileStream = fs.createReadStream(FILE_NAME_LOCAL);
// Call S3 to retrieve upload file to specified bucket
const uploadParams = {
Bucket: BUCKET_NAME,
Key: FILE_NAME_S3,
Body: fileStream,
ACL: FILE_PERMISSION
};
s3.upload(uploadParams, function (err, data) {
if (err) {
console.log("Error", err);
} if (data) {
console.log("Upload Success", data.Location);
}
});

The following works like a charm. (Note the ACL key in params)
下面的工作就像一个魅力。（注意 params 中的 ACL 键）
const params = {
Bucket: bucketName + path,
Key: key,
Body: buffer,
ContentEncoding: 'base64',
ContentType: 'image/jpeg',
ACL:'public-read'
};
await s3.putObject(params).promise();Note: IAM permission "s3:PutObjectACL" must be included in the appropriate policy otherwise you will get Access Deniederrors.
注意：IAM 权限“ s3:PutObjectACL”必须包含在适当的策略中，否则您将收到拒绝访问错误。
