What I want to do is to download file from Amazon S3. I've been looking up the ways to do it but it didn't work well. I saw this question and used one of the answer's code but it didn't work so I am trying to do other way.

What I did is like this.

html

<a href="#" download=" file.file.url "> file.filename </a>

when I click the filename, it actually starts downloading but the file doesn't work. It says we don't support the file type.

I think it's because the path is wrong. When I inspect element on browser, the path looks correct but when I download the file, the file name is like https__... not https://

How can I fix this? What is the cause?
I'm currently checking if it works on local.

Update

my current code
I ended up creating a view to download a file but it still doesn't work even on production. The content of the file is always empty. For image file, it cannot be opened.

def download_file(request, file_pk):
 file = get_object_or_404(File, pk=file_pk)
 name = file.file.name
 path_to_file = "https://%s/media/%s" % (settings.AWS_S3_CUSTOM_DOMAINm name)

 resp = HttpResponse(content_type='application/force-download')
 resp['Content-Disposition'] = "attachment; filename=%s" % name
 resp['X-Sendfile'] = path_to_file
 return resp

That's because of the metadata setting of your file stored in S3.

Can you try to change the metadata of the file you want to download?

The step is below

In your S3 storage, choose the file and select [properties] -> [metadata]
Then, add new metadata as the "Content-Deposition" key and "attachment" value.
The link below is very useful to understand.

Then, you need to change the HTML like this.

 <a href=" file.file.url " download="filename.extension"> file.filename </a>

I'm not sure it works for any type of files. But it worked when I developed a system that downloads a jpeg file.
