Question

我正在使用下面的Cipher模型:(我是从StackOverflow中找到的）

class AESCipher(object):

    def __init__(self, key): 
        self.bs = 32
        self.key = hashlib.sha256(key.encode()).digest()

    def encrypt(self, raw):
        raw = self._pad(raw)
        iv = Random.new().read(AES.block_size)
        cipher = AES.new(self.key, AES.MODE_CBC, iv)
        return base64.b64encode(iv + cipher.encrypt(raw))

    def decrypt(self, enc):
        enc = base64.b64decode(enc)
        iv = enc[:AES.block_size]
        cipher = AES.new(self.key, AES.MODE_CBC, iv)
        return self._unpad(cipher.decrypt(enc[AES.block_size:])).decode('utf-8')

    def _pad(self, s):
        return s + (self.bs - len(s) % self.bs) * chr(self.bs - len(s) % self.bs)

    @staticmethod
    def _unpad(s):
        return s[:-ord(s[len(s)-1:])]

在本地，一切都很好但是当我部署到Google Cloud时，我收到了这个错误：

File "/app/app/models.py", line 108, in decrypt
   enc = base64.b64decode(enc)
 File "/usr/local/lib/python3.4/base64.py", line 90, in b64decode
   return binascii.a2b_base64(s)
binascii.Error: Incorrect padding

服务器中的Python Base64解码异常
