Answer 1

我通过访问我在AWS网站中的S3账户解决了这个问题，并在“ Permissions选项卡下为公众提供了full access Permissions 。 (

顺便说一句，不建议像 AWS 所说的那样，但这是我找到的唯一方法，以便我完成它）

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

即使我面临同样的问题，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）密钥acl: 'public-read'传递给 multerS3 对象参数。

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

如果您没有在 multerS3 对象参数中传递 ACL 属性，则可以。

如果未指定 ACL，则默认使用ACL: 'private'存储文件ACL: 'private'

AWS 支持以下选项：

ACL：私有 | 公众阅读| 公共读写| aws-exec-read | 认证读取| 桶所有者阅读| 桶所有者完全控制

带有acl （访问被拒绝）的multerS3：

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

带有ACL 的multerS3（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);
        }
    })
});

Answer 4

您的 s3 存储桶可能没有公共访问权限。 您可以为您的 s3 存储桶提供公共访问权限（不是首选），否则您可以设置 CloudFront 分发并提供对该分发的必要访问权限（首选），请遵循本指南。
