Django SimpleCMDB 使用序列化

Posted 2021-02-07 孔雀东南飞

如下，前面我们是使用 urllib 方法来转换并传递数据的：

[root@localhost ~]$ tail /data/script/getHostInfo.py 
if __name__ == \'__main__\':
    ....

    data = urllib.urlencode(hostInfo)
    request = urllib2.urlopen(\'http://192.168.216.128:8000/hostinfo/collect/\', data)
    print(request.read())

下面我们用序列化的方式来转换并传递数据，序列化用到的模块是 pickle ，关于序列化参考：https://www.cnblogs.com/pzk7788/p/10348496.html

[root@localhost ~]$ tail /data/script/getHostInfo.py 

import pickle

if __name__ == \'__main__\':
    ....

    data = pickle.dumps(hostInfo)
    request = urllib2.urlopen(\'http://192.168.216.128:8000/hostinfo/collect/\', data)
    print(request.read())

[root@localhost SimpleCMDB]$ cat hostinfo/views.py    # 修改视图函数
from django.shortcuts import render
from django.http import HttpResponse
from hostinfo.models import Host
import pickle

# Create your views here.

def collect(request):
    if request.POST:
        obj = pickle.loads(request.body)    # 先loads()保存成对象
        hostname = obj[\'hostname\']          # 通过对象来获取数据
        ip = obj[\'ip\']
        osver = obj[\'osver\']
        vendor = obj[\'vendor\']
        product = obj[\'product\']
        cpu_model = obj[\'cpu_model\']
        cpu_num = obj[\'cpu_num\']
        memory = obj[\'memory\']
        sn = obj[\'sn\']
 
        host = Host()
        host.hostname = hostname
        host.ip = ip
        host.osver = osver
        host.vendor = vendor
        host.product = product
        host.cpu_model = cpu_model
        host.cpu_num = cpu_num
        host.memory = memory
        host.sn = sn
        host.save()

        return HttpResponse(\'OK\')

    else:
        return HttpResponse(\'No Data!\')

[root@localhost SimpleCMDB]$ python /data/script/getHostInfo.py 
OK

也可以使用 json 模块以序列化的方式来转换并传递数据：

[root@localhost ~]$ tail /data/script/getHostInfo.py 

import json

if __name__ == \'__main__\':
    ....

    data = json.dumps(hostInfo)
    request = urllib2.urlopen(\'http://192.168.216.128:8000/hostinfo/collect/\', data)
    print(request.read())

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

# Create your views here.

def collect(request):
    if request.POST:
        obj = json.loads(request.body)
        hostname = obj[\'hostname\']
        ip = obj[\'ip\']
        osver = obj[\'osver\']
        vendor = obj[\'vendor\']
        product = obj[\'product\']
        cpu_model = obj[\'cpu_model\']
        cpu_num = obj[\'cpu_num\']
        memory = obj[\'memory\']
        sn = obj[\'sn\']
 
        host = Host()
        host.hostname = hostname
        host.ip = ip
        host.osver = osver
        host.vendor = vendor
        host.product = product
        host.cpu_model = cpu_model
        host.cpu_num = cpu_num
        host.memory = memory
        host.sn = sn
        host.save()

        return HttpResponse(\'OK\')

    else:
        return HttpResponse(\'No Data!\')

[root@localhost SimpleCMDB]$ python /data/script/getHostInfo.py 
OK
