Method for forcing direct download by clicking the image link in Django

This example describes how to force direct download by clicking an image link in Django. Share it with you for your reference. The specific analysis is as follows:

When a user clicks an image connection, the image is directly opened in the browser by default. This code changes the image link to download.

This code is also very suitable for downloading large files and basically does not consume memory. Only a portion of the data is read to the memory each time, and then provides the download function.
