python - 如何在 Django rest 框架中自定义 [Authentication credentials were not provided] 错误消息

Question

• 当我没有在 postman 中传递 header 时，DRF 会给我这条消息。

   {"detail": "Authentication credentials were not provided."}
  

• 但我想要一条如下所示的自定义消息。

     {
         "status": False,
         "message": "Authentication credentials were not provided.",
         "data": {}
     }
  

Answer 1

针对所有请求还是仅针对一个或两个 API 端点？

如果是针对某些 api，请按照 Arakkal Abu 在评论中链接您的方式进行操作。我发现 MyCustomExcpetion 的回答很好。

如果它适用于所有端点，请使用像这样的序列化程序/中间件(JWT 示例):

file: url.py
from rest_framework_jwt.views import ObtainJSONWebToken, refresh_jwt_token

url('auth/', ObtainJSONWebToken.as_view(
    serializer_class=CustomJWTSerializer)),


file: serializer.py

from rest_framework import serializers
from rest_framework_jwt.serializers import JSONWebTokenSerializer
from rest_framework_jwt.utils import jwt_encode_handler, jwt_payload_handler

class CustomJWTSerializer(JSONWebTokenSerializer):
    
    def validate(self, attrs):
        credentials = {
                'email': attrs.get('email'),
                'password': attrs.get('password')
            }
        if all(credentials.values()):
            user = authenticate(**credentials)
            if user:
                payload = jwt_payload_handler(user)
                return {
                   'token': jwt_encode_handler(payload),
                   'user': user}
            else:
                return {msg: 'other error msg'}
        else:
            return {
             'status': False,
             'message': 'Authentication credentials were not provided.',
             'data': {}
                 }
