我正在开发使用基于node
的服务器站点的YouTube视频下载器站点。我正在使用npm
名为 ytdl-core
的软件包,此模块返回下载链接。但是,当我单击该链接时,它会将我重定向到"视频预览"而不是"触发下载",
ytdl(url, function(err, format) {
if (err) {res.send('the url is invalid please try again...');}
console.log((format.formats).length);//i am getting value... in console but not outside of the function..
//this object contains all the download links
var links = []
for( var i= 0, len = (format.formats).length; i < len; i++) {
var el = format.formats[i].container;
if ( el === 'mp4') {
var download_url = format.formats[i];
//this push will store the all links in 'links' object..
links.push(download_url);
}
}
console.log(links);
});
因此,当我将链接粘贴到浏览器中时,它会将我重定向到预览而不是触发下载。我得到的链接如下所示:

我的问题是,如何通过单击按钮强制将该视频下载到客户的浏览器?
如果您使用的是 express,使用 res.download(( 可能会有所帮助。它将按照这个思路工作。
res.download(downloadLink, downloadTitle, function(err){
if (err) {
// Handle error, but keep in mind the response may be partially-sent
// so check res.headersSent
} else {
// decrement a download credit, etc.
}
});
祝你好运!希望这有帮助!
我发现非常简单的解决方案是您需要将属性"download='true'
添加到您的HTML代码中! 它看起来像这样
<a href='yourdownloadlink.com/example' download='true'>force download!</a>
