Question

我已将django rest框架版本3.10集成到现有的django 2.2项目中，将api根目录放置在/api。

现在，我正在尝试使用coreapi cli客户端将一些文档上传到服务器。

$ coreapi get http://localhost:8000/openapi
<DownloadedFile '/root/.coreapi/downloads/openapi (4)', open 'rb'>
$ coreapi get http://localhost:8000/api
{
    "invoices": "http://localhost:8000/api/invoices/"
}
$ coreapi action invoices list
Index ['invoices']['list'] did not reference a link. Key 'invoices' was not found.

/openapi是一个端点，可根据请求生成架构并返回

openapi: 3.0.2

      operationId: ListInvoices

                  original_file_name:

              schema:
                required:
                - file_name
                - original_file_name
                properties:
                  file_name:
                    type: string
                  original_file_name:
                    type: string
                    maxLength: 80
                  upload_date:
                    type: string
                    format: date-time
                    readOnly: true
                  data:
                    type: object
                    nullable: true
                  confidence:
                    type: number
                  user_verified:
                    type: boolean

没有什么复杂的问题，发票的路径也不存在（即使应该为/api/invoices）。

我已经成功地使coreapi可以与外部api一起使用，所以这似乎与我配置网址和/或视图有关。

他们两个都很简单。

# urls.py
from rest_framework import routers

from . import views


router = routers.DefaultRouter()
router.register(r'invoices', views.InvoiceViewSet)

urlpatterns = [
    path('api/', include(router.urls)),
]


# views.py
# ... imports ...

class InvoiceSerializer(serializers.HyperlinkedModelSerializer):
    """Defines API representation of invoices"""

    class Meta:  # pylint:disable=too-few-public-methods, missing-docstring
        model = Invoice
        fields = (
            'file_name',
            'original_file_name',
            'upload_date',
            'data',
            'confidence',
            'user_verified',
        )


class InvoiceViewSet(viewsets.ModelViewSet):
    """Defines api views for invoices"""
    # default permissions are set in settings.py
    parser_classes = (JSONParser, XMLParser, FormParser, MultiPartParser)
    queryset = Invoice.objects.all()
    serializer_class = InvoiceSerializer

    @action(methods=['post'], detail=True)
    def upload_with_ground_truth_file(self, request, pk):
        pass

似乎我缺少了显而易见的东西。我需要配置什么才能使用coreapi客户端使用我的api？

Answer 1

我遇到了相同的错误-python 3.8.5，Django 3.1，DRF 3.12.1。对我来说，相似之处在于coreapi返回了DownloadedFile而不是Document，这似乎是在coreapi收到了意外的内容类型时发生的。 / p>

对我来说，解决方案是：

pip install openapi-codec（如果尚未安装）
coreapi get http://localhost:8000/openapi?format=openapi-json --format=openapi

您会知道它成功了，因为您将看不到DownloadedFile的任何提及，而是看到了可用标签/操作的摘要。

不确定为什么要强制使用格式。

如何在Django Rest框架中使用coreapi客户端？
