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.');
})
});
我需要将上传的文件通过cloudfront下载,如果我认为正确,我需要设置文件权限:每个人打开/下载,Folder2应该公开(通过菜单Make Public)。所以有2个问题:
1)如何在上传的文件\文件夹中设置\ modify权限?
2)如何使用AWS SDK for node.js公开文件夹。

找到它 http://docs.aws.amazon.com/AmazonS3/latest/dev/ACLOverview.html#CannedACL
需要在putObject中添加选项:
ACL:'public-read'

这是一个工作代码段,该代码段将本地文件(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);
}
});

以下内容具有魅力。 (请注意参数中的ACL键)
const params = {
Bucket: bucketName + path,
Key: key,
Body: buffer,
ContentEncoding: 'base64',
ContentType: 'image/jpeg',
ACL:'public-read'
};
await s3.putObject(params).promise();
注意:IAM权限“ s3:PutObjectACL ”必须包含在适当的策略中,否则会出现访问被拒绝错误。>
