meteor - 使用 Meteor Slingshot 上传到 s3 的文件停止工作，出现错误 403

Question

一段时间以来，我一直在使用流星弹弓将文件上传到亚马逊 S3。突然之间，我的上传功能似乎都不起作用。尝试上传文件时出现以下错误。

Error uploading errorClass {error: "Forbidden - 403", reason: "Failed to upload file to cloud storage", details: undefined, message: "Failed to upload file to cloud storage [Forbidden - 403]", errorType: "Meteor.Error"…}

上周所有上传工作正常，突然间我在所有项目中都遇到了上述错误。我不知道 slingshot 包是否有问题，或者是否对 s3 策略进行了一些更改。

这是我正在使用的代码

Slingshot.fileRestrictions("myFileUploads", {
    allowedFileTypes: ["image/png", "image/jpeg", "image/gif" ,],
    maxSize: null // 10 MB (use null for unlimited).
});


Slingshot.createDirective("myFileUploads", Slingshot.S3Storage, {
    bucket: "*****",
    acl: "public-read",
    region : "ap-southeast-1",
    AWSAccessKeyId : "MyAccessKey",
    AWSSecretAccessKey : "MySecretKey",

    authorize: function () {
       return true;
    },

    key: function (file) {
        var imageName = getUniqueID()
        return  "images/" + imageName;
    }
});

getUniqueID = function(){
    this.length = 8;
    this.timestamp = +new Date;
    var ts = this.timestamp.toString();
    var parts = ts.split( "" ).reverse();
    var id = "";
    var _getRandomInt = function( min, max ) {
        return Math.floor( Math.random() * ( max - min + 1 ) ) + min;
    }
    for( var i = 0; i < this.length; ++i ) {
        var index = _getRandomInt( 0, parts.length - 1 );
        id += parts[index];  
    }
    return id;
}

这是我的 CORS 配置

<CORSConfiguration xmlns="http://s3.amazonaws.com/doc/2006-03-01/">

        <MaxAgeSeconds>3000</MaxAgeSeconds>
        <AllowedHeader>*</AllowedHeader>
    </CORSRule>
</CORSConfiguration>

还有我的存储桶政策

    "Statement": [
        {
            "Sid": "PublicReadGetObject",

            "Principal": "*",
            "Action": "s3:GetObject",
            "Resource": "arn:aws:s3:::MyBucketName/*"
        }
    ]
}
