API-json格式、API-shell格式-创新互联
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]: >
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]: >
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' 另外有需要云服务器可以了解下创新互联scvps.cn，海内外云服务器15元起步，三天无理由+7*72小时售后在线，公司持有idc许可证，提供“云服务器、裸金属服务器、高防服务器、香港服务器、美国服务器、虚拟主机、免备案服务器”等云主机租用服务以及企业上云的综合解决方案，具有“安全稳定、简单易用、服务可用性高、性价比高”等特点与优势，专为企业上云打造定制，能够满足用户丰富、多元化的应用场景需求。
