1. 内部重构#

2. 外部重构#

website/blog/urls.py

website/website/urls.py

3. 两种参数处理方式 #

1. blog/index/?id=1234&name=bikmin#

#urls.py

url(r'^blog/index/$','get_id_name')

#views.py

from django.http import HttpResponse
from django.template import loader,Context

def get_id_name(request):
  html = loader.get_template("index.html")
  id = request.GET.get("id")
  name = request.GET.get("name")
  context = Context({"id":id,"name":name})
  return HttpResponse(html.render(context))

#index.html

<body>
  <li>id:{{ id }}</li>
  <li>name:{{ name }}</li>
</body>

效果如下

2. blog/index/1234/bikmin#

#urls.py

url(r'^blog/index/(\d{4})/(\w+)/$','blog.views.get_id_name')

#views.py

from django.http import HttpResponse
from django.template import loader,Context

def get_id_name(request,p1,p2):
  html = loader.get_template("index.html")
  context = Context({"id":p1,"name":p2})
  return HttpResponse(html.render(context))

#index.html

<body>
  <li>id:{{ id }}</li>
  <li>name:{{ name }}</li>
</body>

效果如下：

3.blog/index/1234/bikmin (和-2不一样的在于views.py,接收的参数名是限定的）#

#urls.py

#限定id，name参数名
url(r'blog/index/(?P<id>\d{4})/(?P<name>\w+)/$','get_id_name')

#views.py

from django.http import HttpResponse
from django.template import loader,Context

def get_id_name(request,id,name):
  html = loader.get_template("index.html")
  context = Context({"id":id,"name":name})
  return HttpResponse(html.render(context))

#index.html

<body>
  <li>id:{{ id }}</li>
  <li>name:{{ name }}</li>
</body>

效果如下
