使用远程文件的下载属性 [英] Using download attribute with remote file

问题描述

我试图让下载属性在远程链接上映像。

这里是我试图完成的一个例子： $ b

 < a id ='image' href ='remoteFileName.jpg'download ='newFileName.jpg'/> 
  

所以当点击链接而不是浏览器下载remoteFileName.jpg时，它会将其保存为newFileName .jpg

我以某种方式理解交叉来源策略，它是这不起作用的原因。我正在寻找一个解决这个问题的办法，有什么想法吗？

解决方案

如果您无法自行托管文件，可以通过传递代理服务器来解决此问题。通过端点一个文件名，服务器可以管理下载过程并避免跨域挂断。

I'm trying to get the download attribute to work on a remote link to image.

Here is an example of what I am trying to accomplish:

<a id='image' href='remoteFileName.jpg' download='newFileName.jpg' />

So when the link is clicked instead of the browser downloading remoteFileName.jpg, it will save it as newFileName.jpg

I understand the cross origin policy somehow, that it is the reason why this doesn't work. I'm looking for a workaround for this, any ideas?

解决方案

If you're unable to host the file yourself, you might be able to get around this by having a pass through proxy that you host. Pass the endpoint a filename and the server could manage the download process and avoid the cross domain hangups.
