下载表情包

有时候需要将抖音的表情包弄去wx，vivo手机是可以直接拖过去的，但是别的手机咋整？请看下文

将所有要的表情包发给一个朋友，当中聊天记录，打开F12往上滚，确保你要的表情包都被渲染出来。然后执行以下代码。可以得到一个变量imgSrcs ，这个是所有表情包的url地址（目前是这样，如果抖音不改就是可以这样执行的）

const imgSrcs = Array.from(document.querySelectorAll('.j1fggzIT img'))
  .map(img => img.src);

目前这些地址都是GIF格式，然后替换一下js文件中的imgSrcs变量，然后执行js文件，就可以下载所有的表情包了。（AI是个好东西，这种node脚本都不用自己写了）
