打开某瓜视频网站的某个列表页，例如 宠物 列表页， 然后按 F12 打开开发者工具，切换到控制台面板，将以下代码粘贴进去，再按 Enter 回车键执行即可。
async function getVideoUrl(url) {
let iframe = document.createElement('iframe')
document.body.appendChild(iframe)
try {
await new Promise((resolve, reject) => Object.assign(iframe, {
onload: resolve, onerror: reject, src: url }))

}
else{
videoRes = iframe.contentWindow._SSR_HYDRATED_DATA.anyVideo.gidInformation.packerData.videoResource;
}
let {
video_list: videoList } = videoRes.normal

let {
main_url: videoUrl } = videoList[key]
return videoUrl
} finally {
document.body.removeChild(iframe)
}
}

脚本首先遍历列表页所有视频的链接地址，然后创建一个iframe并把iframe的src设置为单个视频链接地址，在iframe的window._SSR_HYDRATED_DATA.anyVideo.gidInformation.packerData.video.videoResource.normal.video_list里获得视频播放地址，最后显示一个进度条下载视频。
