抖音抓取实战，为什么没有抓取数据？例如：有个互联网的电商生鲜公司，这个公司老板想在一些流量上投放广告，通过增加公司产品曝光率的方式，进行营销，在投放的选择上他发现了抖音，抖音拥有很大的数据流量，尝试的想在抖音上投放广告，看看是否利润和效果有收益。他们分析抖音的数据，分析抖音的用户画像，判断用户的群体和公司的匹配度，需要抖音的粉丝数，点赞数，关注数，昵称。通过用户喜好将公司的产品融入到视频中，更好的推广公司的产品。一些公关公司通过这些数据可以找到网红黑马，进行营销包装。源码：https://github.com/limingios/dockerpython.git （douyin）

在这里还是要推荐下我自己建的Python开发学习群:683380553，群里都是学Python开发的，如果你正在学习Python ，小编欢迎你加入，大家都是软件开发党，不定期分享干货（只有Python软件开发相关的），包括我自己整理的一份2018最新的Python进阶资料和高级开发教程，欢迎进阶中和进想深入Python的小伙伴

抖音分享页面

• 介绍

• https://www.douyin.com/share/user/用户ID，用户ID通过源码中的txt中获取，然后通过链接的方式就可以打开对应的web端页面。然后通过web端页面。爬取基本的信息。

PS：text文本中的数据1000条根本不够爬太少了，实际上是app端和pc端配合来进行爬取的，pc端负责初始化的数据，通过userID获取到粉丝列表然后在不停的循环来进行爬取，这样是不是就可以获取到很大量的数据。
