#此程序用来发post请求
from urllib import request
from urllib import parse

def say_hello(urls,brushNum):
    for i in range(brushNum):

            "Connection": "keep-alive"
        }
        
        #定义post内容
        data = {}
        data['cmd'] = 'a'
        pse = parse.urlencode(data).encode('utf-8')

        req = request.Request(url,headers=req_header)
        #发送请求
