Django:handler403 不起作用，但 404 起作用 [英] Django: handler403 doesn't work, but 404 does

问题描述

以下是 MyProj/urls.py 的内容:

from django.contrib import admin
from django.urls import path, include

urlpatterns = [
    path('admin/', admin.site.urls),
    path('', include('general.urls')), # Main app
]

handler403 = 'general.views.handler403'
handler404 = 'general.views.handler403'

如您所见，两个处理程序都指向同一个视图，而我最需要的第一个视图不起作用！例如，/obj/12 的其他用户的数据显示默认浏览器 403 页面:

As you can see, both handlers point to the same view, and first one, which I need most, doesn't work! For example, data of other's user at /obj/12 shows default browser 403 page:

[22/Jan/2019 08:39:14] "GET/obj/12 HTTP/1.1" 403 0

[22/Jan/2019 08:39:14] "GET /obj/12 HTTP/1.1" 403 0

但第二个运行良好并显示正确的页面(当尝试访问 /obj/768 中的一些不存在的数据时).为什么以及如何解决?

But the second one works well and shows correct page (when try to access some not existing data at /obj/768). Why and how can I solve it?

调试模式已关闭.我的 Django 版本是 2.0.6

The debug mode is off. My Django version is 2.0.6

更新.

handler403.py 文件的内容:

from django.shortcuts import render_to_response

def handler403(request, *args, **argv):
    print('Handler 403 was called!')
    u = request.user
    params = {
        'user': u,
    }
    response = render_to_response('403.html', params)
    response.status_code = 403
    return response

字符串 Handler 403 was called! 在我尝试获取此页面时从未打印过.

The string Handler 403 was called! is never printed when I try to get this page.

推荐答案

我猜你的视图会返回一个 django.http.HttpResponseForbidden 而不是引发 django.core.exceptions.PermissionDenied 异常.

My guess is that your views returns a django.http.HttpResponseForbidden instead of raising a django.core.exceptions.PermissionDenied exception.

只有 PermissionDenied 异常被 handler403 处理，一个 HttpResponseForbidden 原样返回.

Only the PermissionDenied exception gets handled by handler403, a HttpResponseForbidden is returned as is.
