一、API-json格式 （应用程序接口）

1、添加url：hostinfo/getjson/

[root@133 simplecmdb-json]# vim /opt/python/django/simplecmdb-json/simplecmdb/urls.py
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'),
)

2、在视图里面定义函数

[root@133 simplecmdb-json]# vim /opt/python/django/simplecmdb-json/hostinfo/views.py
from hostinfo.models import Host,HostGroup #需要倒入HostGroup

#增加一个函数，
def getjson(req):
    ret_list = []
    hg = HostGroup.objects.all()
    for g in hg:
        ret = {'groupname':g.groupname,'members':[]}
        for h in g.members.all():
            ret_h = {'hostname':h.hostname,'ip':h.ip}
            ret['members'].append(ret_h)
        ret_list.append(ret)
    return HttpResponse(json.dumps(ret_list))

3、web访问：http://112.65.140.13:8080/hostinfo/getjson/得到Json数据：

[root@133 simplecmdb-json]# curl http://112.65.140.133:8080/hostinfo/getjson/
[{"groupname": "group1", "members": [{"ip": "112.65.140.132", "hostname": "localhost.localdomain"}, {"ip": "192.168.1.168", "hostname": "test"}]}, {"groupname": "group2", "members": []}]

In [5]: import urllib,urllib2

In [6]: urllib2.urlopen('http://112.65.140.133:8080/hostinfo/getjson/')
Out[6]: <addinfourl at 33716920 whose fp = <socket._fileobject object at 0x1fc33d0>>

In [7]: req = urllib2.urlopen('http://112.65.140.133:8080/hostinfo/getjson/')

In [8]: req.read()
Out[8]: '[{"groupname": "group1", "members": [{"ip": "112.65.140.132", "hostname": "localhost.localdomain"}, {"ip": "192.168.1.168", "hostname": "test"}]}, {"groupname": "group2", "members": []}]'

In [9]: req.read()
Out[9]: ''

In [1]: import json
In [3]: req = urllib2.urlopen('http://112.65.140.133:8080/hostinfo/getjson/')
In [4]: data = req.read()
In [11]: d = json.loads(data)
In [12]: d
Out[12]:
[{u'groupname': u'group1',
  u'members': [{u'hostname': u'localhost.localdomain',
    u'ip': u'112.65.140.132'},
   {u'hostname': u'test', u'ip': u'192.168.1.168'}]},
 {u'groupname': u'group2', u'members': []}]
 
 In [13]: for i in d : print i
{u'groupname': u'group1', u'members': [{u'ip': u'112.65.140.132', u'hostname': u'localhost.localdomain'}, {u'ip': u'192.168.1.168', u'hostname': u'test'}]}
{u'groupname': u'group2', u'members': []}

二、API-shell格式

方法相同

1、添加url：hostinfo/getshell/

[root@133 simplecmdb-json]# vim /opt/python/django/simplecmdb-json/simplecmdb/urls.py
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/getshell/$','hostinfo.views.getshell'),
)

2、在视图里面定义函数

vim /opt/python/django/simplecmdb-json/hostinfo/views.py
 
#增加getshell的方法：
 def getshell(req):
    res = ''
    hg = HostGroup.objects.all()
    for g in hg:
        groupname = g.groupname
        for h in g.members.all():
            hostname = h.hostname
            ip = h.ip
            res += groupname+' '+hostname+' '+ip +'\n'
    return HttpResponse(res)

3、访问测试：

访问测试
[root@133 simplecmdb-json]# curl http://112.65.140.133:8080/hostinfo/getshell/
group1 localhost.localdomain 112.65.140.132
group1 test 192.168.1.168

In [1]: import urllib,urllib2

In [2]: urllib2.urlopen('http://112.65.140.133:8080/hostinfo/getshell/')
Out[2]: <addinfourl at 33701040 whose fp = <socket._fileobject object at 0x1e74150>>

In [3]: req = urllib2.urlopen('http://112.65.140.133:8080/hostinfo/getshell/')

In [4]: req.read()
Out[4]: 'group1 localhost.localdomain 112.65.140.132\ngroup1 test 192.168.1.168\n'
