編寫一個API，當我們訪問 http://192.168.216.128:8000/hostinfo/getjson 時，返回 json 格式的主機組和組成員信息：

[root@localhost SimpleCMDB]$ cat SimpleCMDB/urls.py
....
urlpatterns = patterns(‘‘,
    ....
    url(r‘^hostinfo/getjson/$‘, ‘hostinfo.views.getjson‘),
)

[root@localhost SimpleCMDB]$ cat hostinfo/views.py
from django.shortcuts import
 
 render
from django.http import HttpResponse
from hostinfo.models import Host, HostGroup
import json

....

def getjson(request):
    data = []
    host_group = HostGroup.objects.all()
    for group in host_group:
        result = {‘groupname‘: group.group_name, ‘members‘: []}
        for hosts in
 
 group.group_members.all():
            hostinfo = {‘hostname‘: hosts.hostname,
                        ‘ip‘: hosts.ip,
                        ‘vendor‘: hosts.vendor,
                        ‘product‘: hosts.product,
                        ‘sn‘: hosts.sn,
                        ‘cpu_model‘: hosts.cpu_model,
                        
 
‘cpu_num‘: hosts.cpu_num,
                        ‘memory‘: hosts.memory,
                        ‘osver‘: hosts.osver}
            result[‘members‘].append(hostinfo)
        data.append(result)

    return HttpResponse(json.dumps(data))

編寫一個API，當我們訪問 http://192.168.216.128:8000/hostinfo/getshell 時，返回 shell 格式的主機組和組成員信息（返回 shell 格式的信息，主要是為了我們能在 Linux 下使用 grep 、awk 等對返回的數據做進一步處理）：

[root@localhost SimpleCMDB]$ cat SimpleCMDB/urls.py
....
urlpatterns = patterns(‘‘,
    ....
    url(r‘^hostinfo/getshell/$‘, ‘hostinfo.views.getshell‘),
)

[root@localhost SimpleCMDB]$ cat hostinfo/views.py
from django.shortcuts import render
from django.http import HttpResponse
from hostinfo.models import Host, HostGroup
import json

....def getshell(request):
    data = ‘‘
    host_group = HostGroup.objects.all()
    for group in host_group:
        groupname = group.group_name
        for hosts in group.group_members.all():
            hostname = hosts.hostname
            ip = hosts.ip
            vendor = hosts.vendor
            product = hosts.product
            sn = hosts.sn
            cpu_model = hosts.cpu_model
            cpu_num = hosts.cpu_num
            memory = hosts.memory
            osver = hosts.osver
            data += groupname + ‘ ‘ + hostname + ‘ ‘ + ip + ‘ ‘ + osver + ‘ ‘ + memory + ‘\n‘

    return HttpResponse(data)
