python-3.x - 如何在 django rest 框架中使用 coreapi 客户端？

Question

我已经将 django rest 框架版本 3.10 集成到现有的 django 2.2 项目中，将 api root 放在 /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 是根据请求生成模式并返回的端点

openapi: 3.0.2

                  data:
                    type: object
                    nullable: true
                  confidence:
                    type: number

不存在任何复杂的发票路径(即使它应该是 /api/invoices )。

我已经成功地让 coreapi 与外部 api 一起工作，所以这似乎是我如何配置我的 url 和/或 View 的问题。

他们两个都非常简单。

# 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

似乎我错过了一些非常明显的东西。我需要配置什么才能使用 coreapi 客户端来使用我的 api？

Answer 1

我遇到了同样的错误——python 3.8.5、Django 3.1、DRF 3.12.1。对我来说，相似之处在于 coreapi 返回一个 DownloadedFile 而不是 Document ，这似乎发生在 coreapi 收到它不期望的内容类型时。
对我来说，解决方案是:

pip install openapi-codec (如果你还没有安装)

coreapi get http://localhost:8000/openapi?format=openapi-json --format=openapi

您会知道它成功了，因为您不会看到任何提及 DownloadedFile 的内容，而是看到可用标签/操作的摘要。
不知道为什么强制格式应该是必要的。
