自定义 Django rest 框架身份验证响应 { "detail" ： "Authentication credentials were not provided." }

Question

我正在使用 django 2.1 和 python 3.6 以及 django rest framework 3.8.2 ...我正在尝试找到一种方法在身份验证失败时自定义 json 响应。

我正在使用第三方软件包Django OAuth工具包

我能想到的唯一方法是编写自定义身份验证类

{ "detail": "Authentication credentials were not provided." }

{ "Failure": "Authentication credentials were not provided. xyz etc" }

我试图覆盖基本授权视图

views.py

from django.http import HttpResponse
from oauth2_provider.views.base import TokenView, BaseAuthorizationView
from django.utils.decorators import method_decorator
from django.views.decorators.debug import sensitive_post_parameters
from oauth2_provider.models import get_access_token_model, get_application_model

class CustomAuthorizationView(BaseAuthorizationView):
    def dispatch(self, request, *args, **kwargs):
        self.oauth2_data = {}
        return super().dispatch(request, *args, **kwargs)
    def error_response(self, error, application, **kwargs):
        """
        Handle errors either by redirecting to redirect_uri with a json in the body containing
        error details or providing an error response
        """
        redirect, error_response = super().error_response(error, **kwargs)
        if redirect:
            return self.redirect(error_response["url"], application)
        status = error_response["error"].status_code
        return self.render_to_response("hello", status=status)

urls.py

urlpatterns = [
...
    url(r"o/authorize/", appointmentViews.CustomAuthorizationView, name="authorize"),
    path('o/', include('oauth2_provider.urls', namespace='oauth2_provider')),
...

如果我能提供更多信息，请告诉我！提前谢谢你。

我最终解决了 django rest 的问题，自定义异常处理链接

views.py

from rest_framework.views import exception_handler

def custom_exception_handler(exc, context):
    # Call REST framework's default exception handler first,
    # to get the standard error response.
    response = exception_handler(exc, context)
    if response is not None:
        response.data['status_code'] = response.status_code
    return response

settings.py

REST_FRAMEWORK = {
    'EXCEPTION_HANDLER': 'project.apps.utils.exception.custom_exception_handler'
} 

其中项目(文件夹(>应用程序(文件夹(>实用程序(文件夹(> exception.py>自定义...

响应：

{
    "detail": "Authentication credentials were not provided.",
    "status_code": 401
}
