前言
- 不得不说，微信视频号的下载真的是一个老大难问题，每隔一段时间，之前的方法总会失效，然后又需要去找新的工具。翻来覆去颠倒几次之后烦的不行，于是想着直接通过抓包的方法来下载微信视频号，只要自己实时更新一下微信的解析规则，那么这种手动抓包下载的方法基本上就永久可用，说干就干，我们马上开始搞起来。
具体操作
下载标清版本
- 将要下载的视频分享到微信的文件传输助手中，防止下载错了，之后打开这个视频
- 然后打开Http debug进行抓包，找到finder开头的网址，应该是get方法，资源类型为mp4，复制出来这个网址

- 之后将这个网址中的20302修改成20304，
一个样例

之后就可以放到IDM中进行下载了
如果下载的格式是jpg的，不用管它，直接强制改成mp4的就行了
可以看到这个视频是可以正常查看与播放的
下载高清的微信号视频
- 不过这个视频下载的是标清版的，如果想下载高清版的还需要对链接进行进一步的处理
- 保留encfilekey以及token部分，其他的参数全部删掉
标清的视频链接

- 可以看到这个视频的尺寸已相较之前大了很多
- 播放起来的清晰度也相较之前清晰了很多
自动化操作
- 当然了，这个删除参数的操作很繁琐，而且一不小心就容易出错，因此我把它写成一个Python小程序，可以直接下载下来这个地址中的视频
- 操作界面很简单，没有什么需要说明的地方
