带有 Django 的简单缩略图引发访问被拒绝错误

Question

我正在使用 S3Boto3Storage 将文档保存在我的 aws s3 中，并尝试使用 easy-thumbnails 生成缩略图，请在下面找到代码

型号class

class ThumbnailTestModel(models.Model):
    sample1 = models.FileField(
        storage=S3Boto3Storage(),
        help_text="Field to store the sample document of Professional",
        null=True,
        blank=True,
        upload_to=s3_professional_sample_storage_path)
    sample1_file_name = models.CharField(blank=True,null=True,max_length=1000, default=True)

查看class

class ThumbnailTestModelView(mixins.CreateModelMixin, mixins.ListModelMixin,
            mixins.UpdateModelMixin, viewsets.GenericViewSet):
queryset = ThumbnailTestModel.objects.all()
permission_classes = (AllowAny, )
serializer_class = ThumbnailSerializer

和序列化

class ThumbnailSerializer(serializers.ModelSerializer):
sample1 = serializers.FileField(read_only=True, required=False, allow_null=True)
sample1_base64 = serializers.CharField(write_only=True, required=False, allow_null=True)
sample1_thumbnail = serializers.SerializerMethodField(required=False, read_only=True, allow_null=True)

class Meta:
    model = ThumbnailTestModel
    fields = ['id','sample1', 'sample1_file_name', 'sample1_base64', 'sample1_thumbnail']

def validate(self, validated_data):
    validated_data = super(ProductProfessionalSerializer,
                           self).validate(validated_data)
    sample1_base64 = validated_data.pop('sample1_base64', None)
    if sample1_base64:
        validated_data['sample1'] = ContentFile(
            base64.b64decode(sample1_base64),
            name=validated_data["sample1_file_name"])

def get_sample1_thumbnail(self, instance):
    return AWS_URL + get_thumbnailer(instance.sample1)['avatar'].url

这是我得到的回复

[{"id":5,"sample1":"https://wizcounsel-dev.s3.amazonaws.com/sample_document/None/add_team_2.png","sample1_file_name":"add_team_2.png","sample1_thumbnail":"https://wizcounsel-dev.s3.amazonaws.com/sample_document/None/add_team_2.png.150x100_q85_crop.png"}]

但是访问生成的缩略图 url returns 访问被拒绝错误，同一文件夹中的所有对象实际上 public，在检查 AWS 文件夹时似乎没有有缩略图文件

我是 Django 的超级新手，因此这个问题可能显得幼稚，谢谢

Answer 1

显然缩略图是在本地创建的，这是错误的原因，通过在设置中添加以下行来修复

THUMBNAIL_DEFAULT_STORAGE = 'storages.backends.s3boto3.S3Boto3Storage'
