小编这次要给大家分享的是用代码详解Django如何通过json格式收集主机信息，文章内容丰富，感兴趣的小伙伴可以来了解一下，希望大家阅读完这篇文章之后能够有所收获。
代码如下
Control:
from django.conf.urls import patterns, include, url
from django.contrib import admin
admin.autodiscover()
urlpatterns = patterns('',
# Examples:
# url(r'^$', 'simplecmdb.views.home', name='home'),
# url(r'^blog/', include('blog.urls')),
url(r'^admin/', include(admin.site.urls)),
url(r'^hostinfo/collect/$','hostinfo.views.collect'),
url(r'^hostinfo/getjson/$','hostinfo.views.getjson'),
url(r'^hostinfo/gettxt/$','hostinfo.views.gettxt'),
)View:
