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）

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。

开始python 爬取抖音分享的网站数据

分析分享页面https://www.douyin.com/share/user/76055758243

1.抖音做了反派机制，抖音ID中的数字变成了字符串，进行替换。

{'name':['  ','  ','  '],'value':0},
        {'name':['  ','  ','  '],'value':1},
        {'name':['  ','  ','  '],'value':2},
        {'name':['  ','  ','  '],'value':3},
        {'name':['  ','  ','  '],'value':4},
        {'name':['  ','  ','  '],'value':5},
        {'name':['  ','  ','  '],'value':6},
        {'name':['  ','  ','  '],'value':7},
        {'name':['  ','  ','  '],'value':8},
        {'name':['  ','  ','  '],'value':9},

2.获取需要的节点的的xpath

# 昵称
//div[@class='personal-card']/div[@class='info1']//p[@class='nickname']/text()

#抖音ID
//div[@class='personal-card']/div[@class='info1']//p[@class='nickname']/text()

#工作

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。
