如何使用Django Rest框架和Django在视图中预处理上传的图像

from django.db import models

class Image(models.Model):
    image = models.ImageField(upload_to='images/')

from rest_framework import serializers
from .models import Image

class ImageSerializer(serializers.ModelSerializer):
    class Meta:
        model = Image
        fields = '__all__'

from rest_framework import generics
from .models import Image
from .serializers import ImageSerializer

class ImageUploadView(generics.CreateAPIView):
    queryset = Image.objects.all()
    serializer_class = ImageSerializer

    def perform_create(self, serializer):
        serializer.save()  # 保存图像

        # 在这里可以进行图像的预处理操作，例如调整大小、裁剪等

from django.urls import path
from .views import ImageUploadView

urlpatterns = [
    path('upload/', ImageUploadView.as_view(), name='image-upload'),
]
