requests 获取百度推广信息

2019年的第一篇博客，恩，好久没写过博客了，恩，忘了，哈哈，实在是太懒了

今天写一个爬取百度推广数据的爬虫，当然我写的肯定不是那么的完美，但是能用，大哭

注意：有的时候，get或post方法获取数据是会报ssl等错误，网站要验证啥的，没搞懂，网上搜索，都是设置 verify=False，我也懒得去详细分析，你们要是有兴趣可以去了解一下，然后这么设置了，在GET或者post是会有warning提示，编写代码：

# 禁用ssl发出的警告
requests.packages.urllib3.disable_warnings()

下面代码：

def main():
　　#开启一个session对话
   main_session = requests.session()
   return main_session

def get_cost_info(main_session, endtime, flag1, flag2):
　　#获取省或市在日期或者月份下的消费信息
   if flag1 == 'province':
      splitDimension = "provinceName"
   else:
      splitDimension = "provinceCityName"
   if flag2 == 'month':
      unitOfTime = 3
   else:
      unitOfTime = 5
