在开发中，一般为上传文件单独设立一个接口，以降低程序的耦合度，并且更方便后期的维护。

urls.py

from django.conf.urls import url, includefrom . import views# 路由组件，必须配合视图集使用from rest_framework.routers import SimpleRouterrouter = SimpleRouter()# /books/image/(pk) 提交 form-data：用image携带图片router.register('books/image', views.BookUpdateImageAPIView, 'book')urlpatterns = [ url('', include(router.urls))]

serializers.py

class BookUpdateImageModelSerializer(serializers.ModelSerializer): class Meta: model = models.Book fields = ['image']

views.py

# 上传文件 - 修改头像from rest_framework.viewsets import GenericViewSetfrom rest_framework import mixinsclass BookUpdateImageAPIView(GenericViewSet, mixins.UpdateModelMixin): queryset = models.Book.objects.filter(is_delete=False).all() serializer_class = serializers.BookUpdateImageModelSerializer
