如何从react js中的url下载文件（.jpg/.txt/.pdf/.mp4）？

Question

I am trying to download file from absolute url in react js.

Any help or suggestions are appreciated.

Answer 1

只需使用download属性就可以这样做。

<a href="path to file" download> Download </a>

Answer 2

If you're using React Router, use the below given code.

<Link to="/document/mydocument.pdf" target="_blank" download>Download</Link>

Where /document/mydocument.pdf is inside your public folder.

Answer 3

It would be best if you could create an endpoint which will give you the file with the correct headers. When you create the endpoint, look for Content-Disposition and Content-Type. This will trigger an automatic and consistent download through-out all browsers.

The problem is that front-end code regarding download and the download attribute can behave differently depending on the browser. If you are not able to serve them through an endpoint, I think you will always need to keep the trade-offs in mind like inconsistent behavior through different browsers.
