python实现淘宝定时抢购简易版

获取淘宝服务器时间部分：
getTime.py:

import http.client
import time

if __name__ == '__main__':

    def get_webservertime(host):
        while True:
            try:
                conn = http.client.HTTPConnection(host)
                conn.request("GET", "/")
                r = conn.getresponse()
                ts = r.getheader('date')  # 获取http头date部分
                break
            except Exception as e:
                print(e)
                continue
        # 将GMT时间转换成北京时间
        ltime = time.strptime(ts[5:25], "%d %b %Y %H:%M:%S")
        ttime = time.localtime(time.mktime(ltime) + 8 * 60 * 60)
        dat = "%u-%02u-%02u" % (ttime.tm_year, ttime.tm_mon, ttime.tm_mday)
        tm = "%02u:%02u:%02u" % (ttime.tm_hour, ttime.tm_min, ttime.tm_sec)
        timeStr = dat + ' ' + tm
        return timeStr

主程序部分
mian.py:

    #判断时间是否达到
    if(runTime > tbTime):
        print('时间未到请等待')
        time.sleep(0.05)
