In the above source code, the root path or endpoint will simply render the UI. Return send_file(path, as_attachment=True) from app import appįrom flask import Flask, send_file, upload_form(): Next I will create main.py script that will define all URIs or Action paths for performing certain operations such as rendering the UI and downloading the file from server. This file should be created under the project root directory. Configuring FlaskĬreate the below app.py script (py is the extension to indicate Python script) where I import the flask module.

I may not mention the project root directory in subsequent sections while creating new files and I will assume that I am talking with respect to the project’s root directory. Let’s say I am going to create a project root directory python-flask-file-download. Project Directoryįirst step is to create a project root directory under which I will put all the required files for the project. Now I will create the web application that will download any kind of file which is kept in a server location. The reason could be, you want to generate reports from database and download these reports. There could be any reason to download a file from server. The downloaded file will ask you to choose a file location for saving it.

In this example there will be a simple UI (user Interface), where a link will be provided to the end users and clicking on the download link a file will be download. The file could be of any type of file, i.e., pdf, text, excel, word etc. I will download the file which is kept in the server location. Here I am going to show a simple example on how to download a file from web application using Python Flask.
