先上效果图吧,no pic say bird!
古人云: 知己知彼,百战不殆. 好好去了解一下妹子们的内心想法,早日脱单!
这次我在一个某知名婚恋网站,抓取了一些数据,对她们的内心读白进行分析.
我这次筛选条件: 女性,年龄20-30,学历本科 ,就这些条件.
3000条妹子内心读白词云如下:
放心好了,她们都是追求精神满足而非物质,大部分都是要找生命中的另一半,那她们的另一半会是你吗?

生成词云的代码之前的文章里面有,这里就不展示了,自行前往查阅!
一个高效获取数据的办法.由于并没有什么模拟的操作,一切都可以人工来控制,所以也不需要打开网页就能获取数据!
但我们需要分析这个网页,打开网页 http://www.lovewzly.com/jiaoyou.html 后,按F12,进入Network项中
url在筛选条件后,只有page在发生变化,而且是一页页的累加,而且我们把这个url在浏览器中打开,会得到一批json字符串,所以我可以直接操作这里面的json数据,然后进行存储即可!

代码结构图:
操作流程:
headers 一定要构建反盗链以及模拟浏览器操作,先这样写,可以避免后续问题!
条件拼装
然后记得数据转json格式
然后对json数据进行提取,
把提取到的数据放到文件或者存储起来
主要学习到的技术:
学习requests+urllib
操作execl
文件操作
字符串
异常处理
另外其它基础
请求数据
