下载视频号步骤总体为两个步骤，首先抓包获取视频链接，最后将视频链接替换下可以直接下载，如果需要下载高清视频则需要删除链接中的多余参数。
操作方法
1、下载抓包工具，没有的去下载，链接： https://www.wdzzz.com/ruanjian/tools/1010.html
2、打开HTTP Debugger Pro后，再打开视频号对应的链接，可以看到的GET链接，如下图：
3、将以下代码保存到HTML文件并打开，随便复制一个抓包到的链接，用下面保存好的js代码去生成替换下链接，就可以直接得到下载链接了。

function downloadData(url, e) {
let xhr = new XMLHttpRequest();

xhr.responseType = 'blob';
xhr.onload = (e) => {

link.click();
};
xhr.onprogress = (event) => {
if (event.lengthComputable) {
e.target.textContent = "下载" + (event.loaded * 100 / event.total).toFixed(1) + '%';

xhr.send();
}
function copyUrl(url, e) {
let tmp = e.target.textContent;

点击下载高清视频会在前端后台下载完毕后弹出下载框。
