Django通过json格式收集主机信息

代码如下

Control:

from django.conf.urls import patterns, include, urlfrom django.contrib import adminadmin.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:

from django.shortcuts import renderfrom django.http import HttpResponsefrom hostinfo.models import Host,HostGroupimport pickleimport json# Create your views here.def collect(req): if req.POST: #dic = pickle.loads(req.body) dic = json.loads(req.body) hostname = dic[’hostname’] ip = dic[’ip’] product = dic[’product’] sn = dic[’sn’] vendor = dic[’vendor’] cpu_model = dic[’cpu_model’] cpu_num = dic[’cpu_num’] memory = dic[’memory’] osver = dic[’osver’] try: host = Host.objects.get(sn=sn) except: host = Host() host.hostname = hostname host.ip = ip host.product = product host.sn = sn host.vendor = vendor host.cpu_model = cpu_model host.cpu_num = cpu_num host.memory = memory host.osver = osver host.save() return HttpResponse(’data have save into DB’) else: return HttpResponse(’there is no data from POST method’)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))def gettxt(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)

Model:

from django.db import models# Create your models here.class Host(models.Model): hostname = models.CharField(max_length=50) ip = models.IPAddressField() vendor = models.CharField(max_length=50) product = models.CharField(max_length=50) sn = models.CharField(max_length=50) cpu_model = models.CharField(max_length=50) cpu_num = models.IntegerField() memory = models.CharField(max_length=50) osver = models.CharField(max_length=50) def __unicode__(self): return self.hostnameclass HostGroup(models.Model): groupname = models.CharField(max_length=50) members = models.ManyToManyField(Host)
