我通过转到我的网站S3帐户并在选项卡下向公众提供解决了这个问题。(AWSfull accessPermissions

顺便说一句，不推荐 AWS 说，但这是我找到的唯一方法，以便我完成它）

即使我面临同样的问题，我也得到了解决。

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 键区分大小写，而不是使用acl: 'public-read'usingACL: '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 读取 | 认证阅读 | 桶所有者阅读 | 存储桶所有者完全控制

带acl的 multerS3 （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);
        }
    })
});

带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);
        }
    })
});

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/*"
        }
    ]
}
