修复python3.6.13+django2.2+djangorestframework 3.12.4
使用djangorestframework_simplejwt-4.4.0-py3时，产生的两个bug
bug01：
Internal Server Error: /login/
Traceback (most recent call last):

return token.decode('utf-8')
AttributeError: 'str' object has no attribute 'decode'
解决方式：
rest_framework_simplejwt文件夹下backends.py文件里
class TokenBackend:
def encode(self, payload):
"""
Returns an encoded token for the given payload dictionary.
"""
jwt_payload = payload.copy()
if self.audience is not None:
jwt_payload['aud'] = self.audience
if self.issuer is not None:
jwt_payload['iss'] = self.issuer
token = jwt.encode(jwt_payload, self.signing_key, algorithm=self.algorithm)
return token # .decode('utf-8') 修改的地方
