Answer 1

我通过转到S3网站上的AWS帐户并在full access标签下向公众提供Permissions来解决了这个问题。（

不建议使用AWS所说的方法，但这是我找到的唯一方法，可以完成它

Answer 2

您需要使用IAM创建以下策略：

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Sid": "VisualEditor0",
            "Effect": "Allow",
            "Action": [
                "s3:PutObject",
                "s3:PutObjectAcl"
            ],
            "Resource": "arn:aws:s3:::your-bucket-name-here/*"
        }
    ]
}

Answer 3

即使我遇到了同样的问题，我也解决了。

对我来说，这个问题的原因是我一直在将 acl（访问控制列表）键 acl: 'public-read' 传递给 multerS3 对象参数。

ACL 密钥区分大小写，使用 acl: 'public-read' 而不是使用 ACL: 'public-read' 工作正常。

如果您没有在 multerS3 对象参数中传递 ACL 属性也可以。

如果未指定 ACL，则默认使用 ACL: 'private'

存储文件

AWS 支持以下选项：

multerS3 和 acl（拒绝访问）：

var upload = multer({
   storage: multerS3({
        s3: s3,
        acl: 'public-read',
        bucket: BucketName,
        key: function (req, file, cb) {
            cb(null, new Date().toISOString() + '-' + file.originalname);
        }
    })
});

multerS3 与 ACL（工作正常）：

var upload = multer({
    storage: multerS3({
        s3: s3,
        ACL: 'public-read',
        bucket: BucketName,
        key: function (req, file, cb) {
            cb(null, new Date().toISOString() + '-' + file.originalname);
        }
    })
});
