实现效果:
-
在抖音复制分享链接
-
粘贴分享链接到App, 点击解析
-
点击
去下载
进入浏览器下载
获取无水印视频链接
首先我们使用浏览器打开分享的链接
8.97 teO:/ 一起玩水吧 在这炽热的夏天%%蓝色治愈系 %%夏天 %%游泳 https://v.douyin.com/Y5SpHKD/ 复制此链接，打开Dou音搜索，直接观看视频！
然后打开控制台找到对应的视频, 右键检查可以找到视频的链接
https://www.douyin.com/aweme/v1/play/?video_id=v0200fg10000ca08sgbc77udtm7m06p0
然后在浏览器中打开此链接发现是没有水印的视频, 稍后下载的视频使用的是此链接.
通过测试其他分享的视频发现不同视频对应的video_id不同, 于是需要找到获取video_id的请求.
https://www.douyin.com/aweme/v1/play/?video_id=xxx
通过控制台将设备改成移动端设备, 点击分享的链接
https://v.douyin.com/Y5SpHKD/
, 这时有一条请求进入我们的视线:
https://www.iesdouyin.com/web/api/v2/aweme/iteminfo/?item_ids=7097830584419962125
该请求的响应有我们需要的video_id
该请求有一个参数
item_ids
, 此参数正是点击分享链接后重定向链接的一部分
因此我们只需要解析该链接就可以拿到item_ids
至此,
就得到了下载无水印视频的全过程。
