【数据分析】网页数据提取
huojunan22016/03/14软件综合 IP:北京
最近需要用到XXXXXXXXXXXXXXXXXXXXXX/里的左侧菜单栏的监测曲线里的PM2.5数据,
1.jpg
之前都是逐个手工输入excel,遇到数据量大的时候就很费时费力了,而且页面会定时刷新,刷新后需要重新设定检索时间段,非常麻烦,所以希望能从网页中提取出不同时间点下的PM2.5数据。

先试了excel的数据导入,但是显示不了窗口,

但是可以输出SVG文件,右键可以查看源代码,用SVGdeveloper确定了坐标轴和数据点对应的代码,但是理解不了,烦请各位大侠给讲讲,下面是2016年3月13日00:00时单点SVG对应的代码

方法不对。
定时刷新利用的是浏览器端JS访问服务器API拉取数据,然后数据在本地通过JS绘图。
楼主找到此API后,用wget/curl/.NET的webclient拉取,才是正道。

可以找一个XML解析的示例程序研究看看怎么提取特定元素……

可以从 XXXXXXXXXXXXXXXXXXXXXX/api/getdata_XXXXXXXXXXXXXp 这里获得数据
用post方法向这个地址传送以下参数:
city:"5p2t5bee"             //"杭州"的base64编码
type:"SE9VUg=="           //"HOUR"的base64编码
startTime:"MjAxNi0wMy0xMyAyMDowMDowMA=="                   //开始时间2016-03-13 20:00:00的编码    
endTime:"MjAxNi0wMy0xNCAyMzowMDowMA=="                     //结束时间2016-03-14 23:00:00的编码
然后页面返回数据:

是的,取得了API,或者叫“数据接口”。
楼主可以扩展阅读一下HTTP协议,和base64编码。

所有的编程语言(比如楼上python)都可以解决这两个问题,甚至可以写JS,在浏览器里运行。

最近在自学JS和PYTHON,解决的问题和楼主的正好相反,别人的软件采集的数据用数据库转发过来,我做个数据可视化的网页,以前别人用C++写的图表超丑,JAVASCRIPT的插件好多做出来的效果看起来都高大上。

百度公司有个开源的前端js图表制作库叫做echat,介绍在这里XXXXXXXXXXXXXXXXXXXXXXXX/

这个,算是百度公司为数不多的良心产品吧[s::lol]
