问题描述
我正在开发与选举相关的网络应用程序,并尝试使用 rest_framework_simplejwt.serializers
实现授权令牌概念,在运行此代码时,我遇到了与 str
类相关的错误,如下所示:
AttributeError: 'str' object has no attribute 'decode'
从这部分代码:
data['refresh'] = str(refresh)
class AuthTokenObtainSerializer(TokenObtainPairserializer):
"""
Seializer for th user authentication object.
Returns
-------
json: 'access' and 'token'
"""
default_error_messages = {
'no_active_account': _('No active account found with the given credentials') # noqa: E501
}
def __init__(self,*args,**kwargs):
super().__init__(*args,**kwargs)
self.fields['password'] = serializers.CharField(
style={'input_type': 'password'},trim_whitespace=False
)
self.fields['face_image'] = serializers.ImageField()
def validate(self,attrs):
"""
Validates and authenticate the user.
"""
citizenship_number = attrs.get('citizenship_number')
password = attrs.get('password')
face_image = attrs.get('face_image')
face_id = FaceIdAuthBackend()
user = face_id.authenticate(
citizenship_number=citizenship_number,password=password,face_id=face_image
)
if user is None or not user.is_active:
raise exceptions.AuthenticationFailed(
self.error_messages['no_active_account'],'no_active_account',)
update_last_login(None,user)
data = {}
refresh = self.get_token(user)
data['refresh'] = str(refresh)
data['access'] = str(refresh.access_token)
return data
请帮我解决这个......
解决方法
当我在不同来源寻找解决方案时,我知道这个特定问题来自 PyJWT 包的最新版本,所以我必须将其降级到 v1.7.1,现在我不再遇到这个问题了。
