使用Laravel从Amazon S3直接下载到客户端

Question

I'm trying to make my client side download a big file directly from amazon s3, without downloadin it through the server

using this function:

        $downloadUrl = $s3->getObjectUrl('dev-checkmate', '1.zip', '+5 minutes', array(
            'ResponseContentDisposition' => 'attachment; filename="test.zip"','Content-Type' => 'application/zip',
    ));
    return $downloadUrl;

gives me back a valid url that i can paste to the browser and the download will start, how can i make my web page to start that download without redirecting to the user to the url? (i dont want him to get a blank page, i want him to stay in my web page)

or maybe there is a differnet approach to make the user start the download from s3 directly? the reason i dont want to use my server to do that is the files are pretty big, and i have slow bandwidth on my server.

Answer 1

I suggest you use javascript to open the download URL in a new window/tab. Usually if the browser detects the download the white page closes automatically.

Here's an example that fetches the download URL and then makes the redirect:

$.ajax({
    url: '/download/test.zip', // change this to your real URL
    type: 'GET'
}).done(function(data){
    window.open(data);
});

Alternatively you could insert the download URLs when rendering the view so you don't need to make that ajax call.
