實(shí)現(xiàn)原理:
- urls.py:
from django.conf.urls import url
from django.contrib import admin
from app01 import views
urlpatterns = [
url(r'^admin/', admin.site.urls),
# url(r'^index/', views.index),
url(r'^asdfasdfasdf/(\d+)/(\d+)/', views.index, name='indexx'),
url(r'^login/', views.login),
# url(r'^home/', views.home),
# views.Home.as_view()是固定用法
url(r'^home/', views.Home.as_view()),
# url(r'^detail/', views.detail),
url(r'^detail-(\d+).html', views.detail),
# url(r'^detail-(\d+)-(\d+).html', views.detail),
# url(r'^detail-(?P<nid>\d+)-(?P<uid>\d+).html', views.detail),

- 修改views.py:

'3': {'name': 'root3', 'email': 'root@live.com'},
'4': {'name': 'root4', 'email': 'root@live.com'},
'5': {'name': 'root5', 'email': 'root@live.com'},
}
def index(request,nid,unid):
# indexx
print(request.path_info)
# /asdfasdfasdf/13/
# reverse 能反轉(zhuǎn)
from django.urls import reverse
v = reverse('indexx', args=(90,88,))
print(v)
return render(request, 'index.html', {'user_dict': USER_DICT})

<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
</head>
<body>
<form action="{{ request.path_info }}" method="post">

<li><a target="_blank" href="/detail-{{ k }}.html">{{ row.name }}</a></li>
{% endfor %}

@進(jìn)一步:
- index.html:
<!DOCTYPE html>
<html lang="en">
