需要爬取三峡水库的实时水情数据，可以在网页中选择日期显示水情信息，如果一天天选择再复制数据发现很是耗时，我现在需要将下图中三峡水利枢纽2014年-2016年每天的数据爬下来。
网址如下：

通过浏览器自带的检查工具，右键检查元素，查看 network，查看调用的 ajax API 地址：初步分析后发现是通过ajax调用了以下网址，并用POST传递了一个日期数据，例如今天2017-02-15给该网址：

Header如下：

You can use the requests library to simulate post submission. From the browser inspection tool, you can see that the passed parameter is time:2017-02-07. Define data={"time": date such as 2017-02-07}. Then you can write a loop that loops through the date and adds one day to it. Then r = requests.post("url", data=data, header=****). Take out the data and save it into the database. If each cycle is too slow, you can add gevent, a coroutine library, to speed up the process. If you want to capture 2 years of data, cycle 365*2 times and it will be OK
