抖音去水印方法很简单,以前一直没有去研究,以为搞个去水印还要用到算法去除,直到动手的时候才发现这么简单,不用编程基础都能做。
其实抖音它是有一个隐藏无水印地址的,只要我们找到那个地址就可以了
1、我们在抖音找一个想要去水印的视频链接
注意:这里一定要是https开头的,不是口令
打开浏览器访问:
访问之后会重定向到这个地址,后面有一串数字,这个就是视频的id,他是根据这个唯一id来找到视频播放的
按F12查看网络请求,找到刚刚复制的那个请求地址,在响应头里有一个location链接,访问location的链接

在F12中有许多请求,查看众多的请求里有一个请求是:
请求太多没找到可以直接跳过,直接看:https://aweme.snssdk.com 这个就行了,把id替换一下
https://www.iesdouyin.com/web/api/v2/aweme/iteminfo/?item_ids=7064781119429807363
把这个请求再次用浏览器访问,然后返回了一大串json数据,一直放下翻可以找到这个链接
https://aweme.snssdk.com/aweme/v1/playwm/?video_id=v0200fg10000c85i9ejc77ue0kb2vo80&ratio=720p&line=0
直接用那个链接访问,他其实是一个有水印的链接,仔细观察发现最后那里有一段/playwm
,有两个字母wm其实就是watermark英语单词的缩写,去掉wm后就能得到一个无水印链接了

到这里无水印已经完成了
这里我用的是Java去实现,这个跟语言无关,只要能发请求就行
