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',
 
 
   ],
 
 
  },
 
 
 },
 
 
]

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。
