AWS S3标识的URL连接code导致＆QUOT; SignatureDoesNotMatch＆QUOT; [英] AWS S3 signed url encode resulting "SignatureDoesNotMatch"

问题描述

我使用的科尔多瓦文件传输使用签名的链接直接下载中心从AWS S3的文件，因为科尔多瓦文件传输连接codeS URI时，％的签名被转换成％25，因此，导致签名不匹配

I am using cordova file transfer to dowload a file from aws s3 using signed url, since cordova filetransfer encodes the uri, the "%" in signature is converted to "%25", thus, results in signature mismatch

推荐答案

尝试建立像这样的选择：

Try setting up your options like so:

options = {
            fileKey: 'file',
            fileName: name,
            chunkedMode: false,
            mimeType: 'audio/3gpp',
            httpMethod: 'PUT',
            // Important!
            headers: {
                'Content-Type': 'audio/3gpp' // < Set explicitly otherwise it becomes multipart/form-data which won't work with S3
            },
            encodeURI: false // < Stops any extra encoding by file transfer logic
        }

我花了很多痛苦的时间越来越pre签署PUT操作;与科尔多瓦/ S3工作。古德勒克。

Took me many painful hours getting pre signed PUTs working with cordova / S3. Goodluck.
