request

1. url传递参数

1)参数没有命名, 如：

users/views

def weather(request, city, year):
    print(city)
    print(year)
    return HttpResponse(‘OK‘)

 

users/urls

from django.conf.urls import url
from . import views

urlpatterns = [
    # url(路径, 视图)
    url(r‘^weather/([a-z]+)/(\\d{4})/$‘, views.weather, name=‘weather‘),
]

 

2) 参数命名, 如

from django.conf.urls import url
from . import views

urlpatterns = [
    # url(路径, 视图)
    # url(r‘^weather/([a-z]+)/(\\d{4})/$‘, views.weather, name=‘weather‘),
    url(r‘^weather/(?P<city>[a-z]+)/(?P<year>\\d{4})/$‘, views.weather),
]

 

(?P<city>  就是给参数命名为city
