Use your code editor to create an app.py file. You then have the ability to use it in any of your view functions. To gain access to the request object in Flask, you will need to import it from the Flask library: from flask import request The request object holds all incoming data from the request, which includes the mimetype, referrer, IP address, raw data, HTTP method, and headers, among other things.Īlthough all the information the request object holds can be useful, for the purposes of this article, you will focus on the data that is normally directly supplied by the caller of the endpoint. To access the incoming data in Flask, you have to use the request object. To activate the project’s virtualenv, run the following command:

#Json query language python install#

The pipenv command will create a virtualenv for this project, a Pipfile, install flask, and a Pipfile.lock. Open your terminal and run the following command:

Even though the example app uses a simplified structure for the view functions and routes, what you learn in this tutorial can be applied to any method of organizing your views like class-based views, blueprints, or an extension like Flask-Via.įirst, you will need to create a project directory. To demonstrate the different ways of using requests, you will need to create a Flask app. This tutorial was verified with Pipenv v2020.11.15, Python v3.9.0, and Flask v1.1.2.

Downloading and installing a tool like Postman will be required for testing API endpoints.

It harnesses Pipfile, pip, and virtualenv into one single command.

This project will use Pipenv, a production-ready tool that aims to bring the best of all packaging worlds to the Python world.

This project will require Python installed in a local environment.

To complete this tutorial, you will need: In this tutorial, you will build a Flask application with three routes that accept either query strings, form data, or JSON objects. Flask, like any other web framework, allows you to access the request data. This payload can be in the shape of query strings, form data, and JSON objects. Web applications frequently require processing incoming request data from users.
