Django实现自定义404,500页面教程
(编辑:jimmy 日期: 2024/11/19 浏览:3 次 )
1.创建一个项目
django-admin.py startproject HelloWorld
2.进入HelloWorld项目,在manage.py的同一级目录,创建templates目录,并在templates目录下新建404.html,500.html两个文件。
3.修改settings.py
(1.)DEBUG修改为False,(2.)ALLOWED_HOSTS添加指定域名或者IP,(3.)指定模板路径 ‘DIRS' : [os.path.join(BASE_DIR,‘templates')],
# SECURITY WARNING: don't run with debug turned on in production! DEBUG = False ALLOWED_HOSTS = ['localhost','www.example.com', '127.0.0.1'] TEMPLATES = [ { 'BACKEND': 'django.template.backends.django.DjangoTemplates', 'DIRS': [os.path.join(BASE_DIR, 'templates')], 'APP_DIRS': True, 'OPTIONS': { 'context_processors': [ 'django.template.context_processors.debug', 'django.template.context_processors.request', 'django.contrib.auth.context_processors.auth', 'django.contrib.messages.context_processors.messages', ], }, }, ]
4.新建一个views.py
from django.http import HttpResponse from django.shortcuts import render_to_response from django.views.decorators.csrf import csrf_exempt @csrf_exempt def hello(request): return HttpResponse('Hello World!') @csrf_exempt def page_not_found(request): return render_to_response('404.html') @csrf_exempt def page_error(request): return render_to_response('500.html')
5.修改urls.py,代码如下
from django.conf.urls import url from django.contrib import admin import HelloWorld.views as view urlpatterns = [ url(r'^admin/', admin.site.urls), url(r'^test$', view.hello), ] handler404 = view.page_not_found handler500 = view.page_error
重新编译,重启uwsgi,输入localhost/HelloWorld/test,显示'Hello World!',输入其它地址会显示404.html内容,如果出错则显示500.html内容。
