# Create namespace for containing Qr Code related operations In order to keep things simple, let's create the Python 3 codes as a single source file and name it as run_app.py:įrom flask import Flask, Blueprint, request, send_fileįrom flask_restplus import Api, Namespace, Resource, fieldsĪpi_blueprint = Blueprint('API', _name_)ĭescription='This is an API for QR code app', Creating the Python 3 code for creating an API endpoint that generates a QR Code image In order to do so, create a requirements.txt file with the following content:Īs shown above, we will need a href="" rel="noopener" target="_blank">flask-restplus, Pillow and qrcode for creating an API endpoint that generates a QR Code image. Specifying the Python 3 dependencies for creating an API endpoint that generates a QR Code imageįirst, let's proceed with installing the Python 3 dependencies for creating an API endpoint that generates a QR Code image into your Python 3 environment. So how can you create an API endpoint that generates a QR Code image? With this in mind, let's look at how we can do so with Python 3 Flask-RESTPlus and python-qrcode. For example, WhatsApp web generates a QR Code image that encodes a code for WhatsApp app to sign in the user. When you have an API endpoint that generates a QR Code image, another device with a QR Code scanner will be able to get the encoded value to perform some action.
