详解cgi向文本或者数据库写入数据实例代码

#coding:utf8 import cgi c = cgi.FieldStorage()#获取表单参数 try: data1 = c['mem'].value#获取表单中mem的值 data2 = c['cpu'].value#获取表单中cpu的值 except KeyError:#如果没获取到数据，就把数据设置为空 data1 = '' data2 = '' if data1 or data2:#判断是否获取到数据 f = open('cgi-bin/1.txt','w',encoding='utf8')#创建文件 f.write(data1 +'%' + '\n')#写入mem的值 f.write(data2 +'%' + '\n')#写入cpu的值 f.close()#关闭文件

#coding:utf8 import psutil import urllib.parse import urllib.request test_data = {'mem':psutil.virtual_memory().percent,'cpu':psutil.cpu_percent()} test_data_urlencode = urllib.parse.urlencode(test_data).encode('utf8')#把字典转为urlencode格式并解码为字节流 requrl = "http://127.0.0.1:8000/cgi-bin/updata.py" req = urllib.request.Request(url=requrl,data=test_data_urlencode)#url带参数去请求服务器 res_data = urllib.request.urlopen(req)#提交请求
