12：00 在看 真爱
来源：Python绿色通道
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!
我之前写了一个抓取妹子资料的文章，主要是使用selenium来模拟网页操作，然后使用动态加载，再用xpath来提取网页的资料，但这种方式效率不高。用Python来找合适的妹子（一）
所以今天我再补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
