如何通过 HTTP 请求提供临时文件（非静态）？

Question

I have a Python REST server, that is able to download and write a temporary file using Python TempFile. That is, at request time I have aa file in the filesystem of the server, but it is not permanent so the client cannot access it statically (Ie via http://myserver/path-to-my-file ). I need a way to access an endpoint , and then get a file returned based on the request. (Ie http://myserver/myendpoint/myrequestparameters)

How does that work over HTTP? Is it possible?

(For context, right now I am serving the file encoded as string using base64 encoding and utf-8 decoding, but my frontend application needs a direct download link)

I believe there's a dedicated response type for such stuff in django . Assuming send_file is your endpoint:

from django.http import FileResponse

def send_file(response):

    img = open('my_image_file.jpg', 'rb')

    response = FileResponse(img)

    return response
