CMDB服务器管理系统【s5day88】：采集资产之整合插件

以后导入配置文件不用去from conf而是导入from lib.config，因为在这可以导入global_settings和settings.py

import sys
import os
import importlib
import requests
BASEDIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))
sys.path.append(BASEDIR)
os.environ['AUTO_CLIENT_SETTINGS'] = "conf.settings"
from lib.config import settings
 
server_info = {}
for k,v in settings.PLUGIN_ITEMS.items():
    # 找到v字符串：src.plugins.nic.Nic，src.plugins.disk.Disk
    module_path,cls_name = v.rsplit('.',maxsplit=1)
    module = importlib.import_module(module_path)
    cls = getattr(module, cls_name)
    obj = cls()#就是咋们的对象
    ret = obj.process()#执行process方法 ret是v那k是什么？
    server_info[k] = ret
 
requests.post(
    url=settings.API,
    data=server_info
)

写成函数　

auto_client\run.py

import sys
import os
import importlib
import requests
BASEDIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))
sys.path.append(BASEDIR)
os.environ['AUTO_CLIENT_SETTINGS'] = "conf.settings"
from lib.config import settings
 
if __name__ ==  '__main__':
    func()

auto_client\src\plugins\__init__.py

def func():
    server_info = {}
    for k,v in settings.PLUGIN_ITEMS.items():
        # 找到v字符串：src.plugins.nic.Nic，src.plugins.disk.Disk
        module_path,cls_name = v.rsplit('.',maxsplit=1)
        module = importlib.import_module(module_path)
        cls = getattr(module,cls_name)
        obj = cls()
        ret = obj.process()
        server_info[k] = ret
 
    requests.post(
        url=settings.API,
        data=server_info
    )

写成一个类（和函数没有什么区别）

auto_client\src\plugins\__init__.py

import importlib
import requests
from lib.config import settings
 
class PluginManager(object):
    def __init__(self):
        pass
    def exec_plugin(self):
        server_info = {}
        for k,v in settings.PLUGIN_ITEMS.items():
            # 找到v字符串：src.plugins.nic.Nic，src.plugins.disk.Disk
            module_path,cls_name = v.rsplit('.',maxsplit=1)
            module = importlib.import_module(module_path)
            cls = getattr(module,cls_name)
            obj = cls()
            ret = obj.process()
            server_info[k] = ret
        return server_info
         
"""             
requests.post(
    url=settings.API,
    data=server_info
)
一个文件一个目录只做一件事情
"""

auto_client\run.py

import sys
import os
import importlib
import requests
BASEDIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))
sys.path.append(BASEDIR)
os.environ['AUTO_CLIENT_SETTINGS'] = "conf.settings"
 
from src.plugins import PluginManager
 
if __name__ == '__main__':
    obj = PluginManager()
    server_dict = obj.exec_plugin()
    print(server_dict)

运行截图

写成一个类（实例化之前可以自定义很多操作）

auto_client\run.py

import sys
import os
import importlib
import requests
BASEDIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))
sys.path.append(BASEDIR)
os.environ['AUTO_CLIENT_SETTINGS'] = "conf.settings"
 
from src.plugins import PluginManager
 
if __name__ == '__main__':
    obj = PluginManager()
    server_dict = obj.exec_plugin()
    print(server_dict)

auto_client\src\plugins\__init__.py

import importlib
import requests
from lib.config import settings
 
class PluginManager(object):
    def __init__(self):
        pass
    def exec_plugin(self):
        server_info = {}
        for k,v in settings.PLUGIN_ITEMS.items():
            # 找到v字符串：src.plugins.nic.Nic，src.plugins.disk.Disk
            module_path,cls_name = v.rsplit('.',maxsplit=1)
            module = importlib.import_module(module_path)
            cls = getattr(module,cls_name)
            if hasattr(cls,'initial'):
                obj = cls.initial()
            else:
                obj = cls()
            ret = obj.process()
            server_info[k] = ret
        return server_info
