如DRF文档http://www.django-rest-framework.org/api-guide/parsers/#multipartparser中所述,为了解析multipart / form-data,必须使用MultiPart和form解析器。我很怀疑这是Django Rest Framework中的问题,因为我在他们的github问题上看到了一个解决方案,说它可以使用APIView运行。
from django.contrib.auth.models import User
from rest_framework import viewsets
from api.serializers import UserSerializer,
from rest_framework.parsers import MultiPartParser, FormParser
from rest_framework.response import Response
from rest_framework import status
class UserViewSet(viewsets.ModelViewSet):
"""
API endpoint that allows users to be viewed or edited.
"""
queryset = User.objects.all()
parser_classes = (MultiPartParser, FormParser)
serializer_class = UserSerializer
我向邮递员发送请求的图片,结果:
编辑:添加UserSerializer类
class UserSerializer(serializers.HyperlinkedModelSerializer):
snapcapsules = SnapCapsuleSerializer(
many=True,
read_only=True,
allow_null=True,
)
class Meta:
model = User
fields = ('snapcapsules', 'url', 'username', 'email', 'password', )
write_only_fields = ('password',)
def create(self, validated_data):
user = User.objects.create(
username=validated_data['username'],
email=validated_data['email'],
)
user.set_password(validated_data['password'])
user.save()
return user
def update(self, instance, validated_data):
capsules_data = validated_data.pop('snapcapsules')
for capsule in capsules_data:
SnapCapsule.objects.create(user=instance, **capsule)
return instance
答案 0 :(得分:2)
ContentType
可能不是问题。错误响应指出,UserSerializer
期望payload
或data
,其中包括username
和password
字段
因此,请尝试将这些字段添加到请求正文中,然后重试
Orginal Post的问题是,他在POSTMAN中添加了额外的标头(请参见下图)
。
邮递员会为您添加适当的标题。因此,您不必明确提及它

我删除了一行,然后奏效了!
class UserViewSet(viewsets.ModelViewSet):
"""
API endpoint that allows users to be viewed or edited.
"""
queryset = User.objects.all()
serializer_class = UserSerializer
此外,可以如下重写串行器:
class UserSerializer(serializers.HyperlinkedModelSerializer):
...
def create(self, validated_data):
return User.objects.create_user(
username=validated_data['username'],
email=validated_data['email'],
password=validated_data['password']
)
...
