在线微博数据可视化

在线微博数据可视化，即时采集微博数据，通过不同词云进行展示数据

完整代码gitee地址：https://gitee.com/lyc96/weibo

1.先来效果图（压压惊）

1）输入明星完整名字

2）点击查看后，可以看到明星的言语文字可视化，有六种图形，可以随意切换

2.程序功能介绍

1）根据明星姓名去爬取该明星的微博言论，并存储到文本文件（项目中不涉及任何数据库存储），程序中也会根据日期进行去重爬取，避免程序重复爬取同一条微博。

2）采集好的明星微博文本存储到txt文本中，使用stylecloud进行词云生成图片（有六种图形词云，可以在网页端进行切换）

3.python后端代码
