Contains two files.

3. Modify settings. py

(1 .) DEBUG to False, (2 .) ALLOWED_HOSTS Add the specified domain name or IP address, (3 .) specify the template path 'dirs': [OS. path. join (BASE_DIR, 'templates')],

# SECURITY WARNING: don't run with debug turned on in production!DEBUG = FalseALLOWED_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. Create a new view. py

from django.http import HttpResponsefrom django.shortcuts import render_to_responsefrom django.views.decorators.csrf import csrf_exempt@csrf_exemptdef hello(request): return HttpResponse('Hello World!')@csrf_exemptdef page_not_found(request): return render_to_response('404.html')@csrf_exemptdef page_error(request): return render_to_response('500.html')

5. Modify urls. py. The Code is as follows:

from django.conf.urls import urlfrom django.contrib import adminimport HelloWorld.views as viewurlpatterns = [ url(r'^admin/', admin.site.urls), url(r'^test$', view.hello),]handler404 = view.page_not_foundhandler500 = view.page_error
