  1. models 配置

    class ImageItems(models.Model):
    image = models.ImageField(upload_to='static/images/%Y/%m/%d', null=False, blank=False, verbose_name='图片url')
    
    class Meta:
    verbose_name = '图片集合'
    verbose_name_plural = verbose_name

    2.serializers 配置

    class ListImgSerializer(serializers.Serializer):
    img = serializers.ListField(
    child=serializers.FileField(max_length=100000,
    allow_empty_file=False,
    use_url=True), write_only=True
    )
    img_list = serializers.ListField(
    child=serializers.CharField(max_length=1000, ), read_only=True
    )
    code = serializers.IntegerField(read_only=True)
    
    def create(self, validated_data):
    imgs = validated_data.get('img')
    images = []
    for index, url in enumerate(imgs):
    image = ImageItems.objects.create(image=url)
    imageItems = ImageItemsSerializer(image, context=self.context)
    images.append(imageItems.data['image'])
    return {"img_list": images, "code": 201}
  2. viewSet 配置
    class ImageItemsViewSet(mixins.CreateModelMixin, viewsets.GenericViewSet):
    queryset = ImageItems.objects.all()
    serializer_class = ListImgSerializer
    parser_classes = (MultiPartParser, FileUploadParser,)
