B站视频信息(av号，播放量，弹幕数，硬币数，分享量，评论数，收藏数)爬虫 2 | 3 | ## 相关文章:[B站用户信息爬虫](https://github.com/zhang0peter/bilibili-user-information-spider) 4 | 数据结果在最下面。
5 | 6 | ## 准备工作 7 | 8 | 我使用的是Python3，数据库用的是Python自带的sqlite，使用requests库爬取。
9 | 安装需要的库
10 | 11 | ```python 12 | pip install requests 13 | ``` 14 | 15 | 直接刷新视频页面来获取视频信息太慢，通过api地址能快速获取视频信息。
16 | 如：https://api.bilibili.com/x/web-interface/archive/stat?aid=19801429，
17 | 在浏览器中打开这个页面，可以获取json格式的数据：
18 | ```javascript 19 | { 20 | "code":0, 21 | "message":"0", 22 | "ttl":1, 23 | "data":{ 24 | "aid":19801429, 25 | "view":583, 26 | "danmaku":4, 27 | "reply":2, 28 | "favorite":378, 29 | "coin":6, 30 | "share":6, 31 | "now_rank":0, 32 | "his_rank":0, 33 | "no_reprint":0, 34 | "copyright":2} 35 | } 36 | ``` 37 | 使用requests库获取数据，用concurrent.futures的多线程来加快爬取的速度，我采用的是32线程爬取。
38 | 39 | ## 数据获取 40 | B站对爬虫采取的是一旦发现，就封ip半小时到1天不等的时间。
41 | 但是如果使用代理，爬取总共数量1900万(在2018年2月24，B站视频av号已经到2000万了)个视频信息需要花费很多时间。
42 | 幸运的我发现我的服务器爬取B站视频信息不会被封ip，于是我就把爬虫放到服务器上跑了整整5天，获得了1300万条有效数据。数据库文件有300M，GitHub无法上传，
43 | 我放到了百度云里：https://pan.baidu.com/s/1ggxaanL ，密码: i8mb。
44 | 45 | ## 数据处理 46 | 我使用的是SQLiteStudio进行数据库操作
47 | ### 查询播放量前十的视频 48 | ![](image/查询播放量前十的视频.png)
49 | ### 查询收藏数前十的视频 50 | ![](image/查询收藏数前十的视频.png)
51 | ### aid号与播放量关系 52 | 可以从下图看出，随aid号的增加，视频的平均播放量在变少，爆款视频也在变少。
53 | 我认为主要原因是B站UP主变多，把许多大的UP主的粉丝分流了部分。
54 | 画图代码见 [aid号与播放量关系.py](code/aid号与播放量关系.py)
55 | ![](image/aid号与播放量.png)
56 | ### 收藏数与硬币数关系 57 | 画图代码见 [收藏数与硬币数关系.py](code/收藏数与硬币数关系.py)
58 | ![](image/收藏数与硬币数关系.png)
