如何在HTML中为mongodb数据创建下载链接？

Question

I've seen this question How can I create download link in html? . One solution to create a link for download is using this <a href="link/to/your/download/file" download="filename">Download link</a> . However, if the data source is mongodb, what href should be set?

Answer 1

You have to give the path of the file where it's available in the database. Let's say your file is http://www.w3schools.com/images/myw3schoolsimage.jpg so in the response where you have to return the location you can put

<a href="http://www.w3schools.com/images/myw3schoolsimage.jpg" download> [<img border="0" src="https://i.stack.imgur.com/S7CZv.jpg" alt="W3Schools" width="104" height="142">][1]
