Answer 1

我通過訪問我在AWS網站中的S3賬戶解決了這個問題，並在“ Permissions選項卡下為公眾提供了full access Permissions 。 (

順便說一句，不建議像 AWS 所說的那樣，但這是我找到的唯一方法，以便我完成它）

Answer 2

您需要使用 IAM 創建以下策略：

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

Answer 3

即使我面臨同樣的問題，我也解決了。

對我來說，這個問題的原因是我一直在將 acl（訪問控制列表）密鑰acl: 'public-read'傳遞給 multerS3 對象參數。

ACL 密鑰區分大小寫，而不是使用acl: 'public-read' using ACL: 'public-read'工作正常。

如果您沒有在 multerS3 對象參數中傳遞 ACL 屬性，則可以。

如果未指定 ACL，則默認使用ACL: 'private'存儲文件ACL: 'private'

AWS 支持以下選項：

ACL：私有 | 公眾閱讀| 公共讀寫| aws-exec-read | 認證讀取| 桶所有者閱讀| 桶所有者完全控制

帶有acl （訪問被拒絕）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);
        }
    })
});

帶有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 存儲桶可能沒有公共訪問權限。 您可以為您的 s3 存儲桶提供公共訪問權限（不是首選），否則您可以設置 CloudFront 分發並提供對該分發的必要訪問權限（首選），請遵循本指南。
