from django.http import HttpResponse
import datetime
def current_datetime(request):
now = datetime.datetime.now()
html = "<html><body>It is now %s.</body></html>" % now
return HttpResponse(html)
2、URL
from django.contrib import admin
from django.urls import path
from mysite.views import hello, current_datetime
urlpatterns = [
path('admin/', admin.site.urls),
path('hello/', hello),
path('time/', current_datetime)
]
二、显示当前时间和加上时间偏差量的时间（使用正则表达式）
1、VIEW
from django.http import Http404, HttpResponse
import datetime
def hours_ahead(request, offset):
try:
offset = int(offset)
except ValueError:
raise Http404()
dt = datetime.datetime.now() + datetime.timedelta(hours=offset)
html = "<html><body>In %s hour(s), it will be %s.</body></html>" % (offset, dt)
return HttpResponse(html)
