Python script capture server data is submitted to the Django Web server via API and then displayed on the page

Python program that collects information about the server

#coding: Utf-8

Import Psutil

Import Urllib

Import Urllib.request

Import Urllib.parse

#import URLLIB2

Import requests

#获取数据

Cpudata = Psutil.cpu_times ()

#处理数据

Cpumax = Cpudata.user+cpudata.system+cpudata.idle

cpuused = Cpudata.user+cpudata.system

Cpuuse = Cpuused/cpumax

#将数据进行打包

data = {"cpuused": Cpuuse}

#sendData = Urllib.parse.urlencode (data)

#sendData = Senddata.encode (' Utf-8 ')

url = "http://192.168.52.129:8000/api/savecpu/"

#定义请求头部

Header = {

}

#定义请求

Res =requests.post (url,data = data)

#req = urllib.request.Request (url,data = senddata,headers = Header,method = ' POST ')

#添加Header

#req. Add_header (headers = header)

#发送请求

#ope = Urllib.request.urlopen (req)

#打印结果

Print (Res.content.decode ())

#print (Ope.read ())

Django creates a project, creates an app, and I've created an API app here

The agent side (Python program) constantly collects the information of the native server, passes the data to the Web server side (Django) through the API, the Web server side receives the data which the interface transmits, the data which passes through in the format saves the data in the database, Extracting data from a database, displaying data in front-end pages

Probably a simple server-"agent end is like this
