使用nodejs 获取百度音乐下载链接
发布于 5个月前 作者 tsq 1026 次浏览

网址:http://115.29.99.116:2015/ 网站是无聊时做的玩的。现在有两个问题请求众大神帮助。 两个问题主要是涉及通过url下载音乐到本地: 1.在html中<a>的href写上歌曲的下载地址，点击时的确会调转到下载的页面，可是还是需要自己手动在地址栏中按一下回车键才能下载。 2.网站也采用的从自己的服务端下载歌曲,使用request获得下载流再传给前端,但是这种做法却使得文件名丢失,具体代码为:

   getPipe: function (req, res) {
       var url = req.param('url');
       if (!url) {
           return res.send('missing some param')
       }
       var options = {
           url: url,
           headers:{
               'Referer': 'http://www.baidu.com'
           }
       };
       var x = request(options);
       req.pipe(x);
       x.pipe(res);
   }

@tsq 之前的方法并没有验证， 使用jquery1.11是可以下载的，但出现的问题是…无法保存。 so 我找到了一个完美的方法 代码来自网络 function download_file(url) { if(typeof(download_file.iframe)== “undefined”) { var iframe = document.createElement(“iframe”); download_file.iframe = iframe; document.body.appendChild(download_file.iframe); } download_file.iframe.src = url; download_file.iframe.style.display = "none";

} 经验证可以下载并能保留文件名
