以下C#代码是解密 API wx.getUserInfo 返回的encryptedData ，但是会出现持续性的解密出来是一串乱码，如解密成功了，持续的全部解密成功， 直到下次有解密失败的，又持续的解密失败。大伙有没有更好的办法吗？            private static byte[] AES_decrypt(string input, string iv, string key)         {             RijndaelManaged aes = new RijndaelManaged();             aes.KeySize = 256;             aes.BlockSize = 128;             aes.Mode = CipherMode.CBC;             aes.Padding = PaddingMode.None;             aes.Key = Convert.FromBase64String(key);             aes.IV = Convert.FromBase64String(iv);             var decrypt = aes.CreateDecryptor(aes.Key, aes.IV);             byte[] xBuff = null;             using (var ms = new MemoryStream())             {                 using (var cs = new CryptoStream(ms, decrypt, CryptoStreamMode.Write))                 {                     byte[] xXml = Convert.FromBase64String(input);                      byte[] msg = new byte[xXml.Length + 32 - xXml.Length % 32];                      Array.Copy(xXml, msg, xXml.Length);                     cs.Write(xXml, 0, xXml.Length);                 }                 xBuff = decode2(ms.ToArray());                            }             return xBuff;         }         private static byte[] decode2(byte[] decrypted)         {             int pad = (int)decrypted[decrypted.Length - 1];             if (pad < 1 || pad > 32)             {                 pad = 0;             }             byte[] res = new byte[decrypted.Length - pad];             Array.Copy(decrypted, 0, res, 0, decrypted.Length - pad);             return res;         }

小程序解密手机号  encryptedData 乱码，python  AES解密乱码怎么办？[图片] 上面有乱码之后，会报一个json的错，
