获取视频信息，切入点是抖音的分享链接

随便找一个视频，获取分享链接

1
尝试臭豆腐肥肠火锅？这味道简直太太太上头了！！%vlog日常 %美食探店 %火锅 %深夜放毒 %美食趣胃计划  https://v.douyin.com/eNBofpr/ 椱制此链接，打开Dou吟搜索，直接觀看视频！

获取到链接：https://v.douyin.com/eNBofpr/ ，后续便以此为测试数据。

打开Chrome调试模式，很轻松的能定位到实际访问的数据接口：https://www.iesdouyin.com/web/api/v2/aweme/iteminfo/?item_ids=6942073391922842894

其中item_ids对应的就是本视频的ID:6942073391922842894，眼尖一点就能发现，这个ID出现在了重定向后的Url中。

下面就简单了，整理一下步骤：

  1. 获取分享链接
  2. 访问分享链接
  3. 通过重定向后的分享链接获取作品实际ID
  4. 调用API接口，获取作品信息

抖音无水印视频

接口分析

上一小结获取的抖音视频信息中，可以在返回结果的video -> play_addr -> url_list找到视频的地址，但是是有水印的。有没有办法获取无水印的视频呢？

观察视频地址：https://aweme.snssdk.com/aweme/v1/playwm/?video_id=v0200fcf0000c1bj4fmluf3igni150tg&ratio=720p&line=0

尝试去掉参数之后发现仍可以正常访问，所以和传入的参数ratio 和line关系不大。正当一筹莫展之际，突然发现https://aweme.snssdk.com/aweme/v1/playwm/ 中的最后一段地址有点奇怪，playvm不像是一个单词。猜想wm是英文水印(water mark)的缩写。

果然，去掉之后是无水印的版本

接口分析

作者信息和作品信息类似，通过客户端拿到分享链接，打开调试模式获取真实接口地址

分享链接：https://v.douyin.com/eNAud7S/
重定向链接：https://www.iesdouyin.com/share/user/76615500441?u_code=19i75j4k2a8c&did=2471341373012760&iid=1407810874127151&sec_uid=MS4wLjABAAAAdeyz1L3UsIm98XsqJyB8DGRgqG_lRWApIECVDSnFQYE&app=aweme&utm_campaign=client_share&utm_medium=ios&tt_from=copy&utm_source=copy
数据接口地址：https://www.iesdouyin.com/web/api/v2/user/info/?sec_uid=MS4wLjABAAAAdeyz1L3UsIm98XsqJyB8DGRgqG_lRWApIECVDSnFQYE

经测试，重定向后的地址参数只有sec_uid是有用的，甚至url结尾的用户ID都是没用的，例如以下两个链接返回的都是相同的信息

https://www.iesdouyin.com/share/user/76615500441?sec_uid=MS4wLjABAAAAdeyz1L3UsIm98XsqJyB8DGRgqG_lRWApIECVDSnFQYE
https://www.iesdouyin.com/share/user/我是帅哥?sec_uid=MS4wLjABAAAAdeyz1L3UsIm98XsqJyB8DGRgqG_lRWApIECVDSnFQYE

虽然能理解接口逻辑，但是这种操作还是蛮奇怪的。那为什么不干脆直接去掉后面的ID呢。😳

信息收集的差不多了，整理一下：

  1. 获取分享链接
  2. 访问分享链接
  3. 通过重定向后的分享链接获取用户的sec_uid
  4. 调用API接口，获取作者信息

逻辑和获取作品信息的非常非常像了，只不过用户无法直接通过id获取数据，猜想是因为ID是数字，容易被爬虫递增爬取。

总结

总体看来，抖音的数据还是非常容易爬取的，接口逻辑非常清晰简单。有机会的话后面聊一聊小红书，小红书的反爬做的是非常厉害。
