これは、AWS の REST 認証用です。私が得る結果は: ulrEncodedResult: k1T%2FqvVoXgEvmdFhTEh71vLDznqEVCyKcslA5RRSB6s%3D
予想される結果: ulrEncodedResult: M%2Fy0%2BEAFFGaUAp4bWv%2FWEuXYah99pVsxvqtAuC8YN7I%3D
認証の正確な手順はすべてここに示されています: http://docs.aws.amazon.com/AWSECommerceService/2011-08-01/DG/rest-signature.html
誰かが私が犯している間違いを見つけることができますか?
