AWS S3签名url编码生成"SignatureDoesNotMatch"

Question

我正在使用cordova文件传输来使用签名网址从aws s3下载文件,因为cordova filetransfer对uri进行编码,签名中的"%"将转换为"%25",从而导致签名不匹配

Answer 1

尝试设置您的选项,如下所示:

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
        }

在使用cordova/S3进行预签名的PUT时,花了很多时间.祝好运.
