Answer 1

即使我也遇到了同样的问题，但我已经解决了。

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 key 区分大小写，而不是使用 acl: 'public-read' 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:

ACL:私有(private) |公众阅读 |公共(public)读写 | aws-exec-读 |认证阅读 |桶拥有者阅读 |桶拥有者完全控制

带有 acl 的 multerS3(访问被拒绝):

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);
        }
    })
});
