8/7 工作总结

1.利用 ansible 自动化工具，获取相应主机的信息

(1) 调用接口得到相应的 ip 链表 (http 协议)

def getHostInfo():
    HostIPList = []
    url = 'http://cmdb.mwbyd.cn/api/host/host/'
    r = requests.get(url)
    result_json = r.json()
    count = 0
    while count != result_json['count']:
        url = url if count == 0 else result_json['next']
        r = requests.get(url)
        result_json = r.json()

        result = result_json['results']
        for host in result:
            HostIPList.append(host['ip'])
            count += 1
        HostIPList.sort()
    return HostIPList

(2)调用 ansible python api 利用 ssh 协议获取相应ip的网络信息，系统信息(json 解析数据)

(3)将获取的数据存到数据库中，调用接口(http协议，身份验证)

 1 class CMDBApi():
 2 
 3     token = ''

18             if response.status_code != 200:
19                 return False, 'fail!'
20             data = json.loads(response.text)

28             if response.status_code < 200 or response.status_code >= 300:

38             if response.status_code != 200:
39                 return False, 'fail!'
40             data = json.loads(response.text)
41             return True, 'succ!'
42         except Exception, ex:
43             return False, str(ex)
