Question

我正在使用Phonegap捕获视频文件并将其上传到Amazon S3和Amazon S3 SDK，以获取请求的预签名网址。在本地使用PHP服务器时捕获和上传工作正常，从Amazon获取预先签名的URL也没有问题。然而，当我结合所有这些东西时：尝试使用生成的预签名网址将捕获的视频上传到亚马逊，我得到“我们计算的请求签名与您提供的签名不匹配。”

以下是获取预签名网址并上传到亚马逊的方法：

uploadFile: function (file) {
    var //path = file.fullPath,
        path = file.localURL,
        name = file.name,
        type = file.type;

    var s3 = new AWS.S3(),
        s3_params = {
        Bucket: 'BUCKET_NAME',
        Key: name,
        Expires: 6000
        //ContentType: type,
        //ACL: 'public-read'
    };

    s3.getSignedUrl('putObject', s3_params, function(err, data){
        if(err){
            console.log(err);
        }
        else{
            var ft = new FileTransfer(),
                url = encodeURI(data);
            console.log(data);
            ft.onprogress = function(progressEvent) {
                if (progressEvent.lengthComputable) {
                    console.log(progressEvent.loaded / progressEvent.total);
                } else {
                    console.log(progressEvent);
                }
            };

            ft.upload(
                path,
                url,
                function(result) {
                    console.log('Upload success: ' + result.responseCode);
                    console.log(result.bytesSent + ' bytes sent');
                },
                function(error) {
                    console.log('Error uploading file ' + path + ': ' + error.code);
                },
                {
                     httpMethod  : 'PUT',
                     fileName    :  name,
                     mimeType    :  type,
                     chunkedMode :  false,
                     headers: {
                         'Content-Type' :  type,
                         'x-amz-acl'    : 'public-read'
                     }
                }
            );
        }
    });
}

我做错了吗？

我知道有关此主题的SO有很多问题/答案，但似乎没有什么对我有用......

请指教！

Answer 1

不太确定，但可能会解决问题。

根据their documentation您可能需要添加＆＃39; ServerSideEncryption＆＃39;在 s3_params 中就像这样

s3_params = {
    Bucket: 'BUCKET_NAME',
    Key: name,
    Expires: 6000
    ServerSideEncryption: 'AES256'
};

希望这会有所帮助

好吧，好像我发现了问题：getSignedUrl返回ALREADY编码的网址。

纠正方法：

 WITH MEMBER Time.T1 AS 'SUM([Time].&[TY].&[0]:[Time].&[TY].&[11])' 
MEMBER Time.T2 AS 'SUM([Time].&[TY].&[0]:[Time].&[TY].&[11])' 
MEMBER Measures.Col1 AS '(Scenario.&[PO], [T1], [GNAm])' 
MEMBER Measures.Col2 AS '(Scenario.&[ACFC], [T2], [GNAm])' 
MEMBER Measures.Diff AS '[Col2] - [Col1]' 
MEMBER Measures.Perc AS 'IIF([Col1] = 0, [Col1], [Diff] / [Col1])', FORMAT_STRING = '#0.00%' 
SELECT {[Col1], [Col2], [Diff], [Perc]} on Columns, Descendants([Account].[Account].[Expenses]) on Rows 
FROM DS_GNA 
WHERE (&[44026-90],&[010000])

}
