Building a REST API with Flask: Creating a Ping Endpoint
Flask is a lightweight web framework in Python that allows you to easily build REST APIs. In this tutorial, we will be creating a simple Ping endpoint using Flask.
Setting up Flask
First, you will need to install Flask using pip:
pip install Flask
Now, let’s create a simple Flask app with a Ping endpoint:
from flask import Flask
app = Flask(__name__)
@app.route('/ping')
def ping():
return 'Pong!'
if __name__ == '__main__':
app.run()
Save the above code in a file called app.py. To run the Flask app, execute the following command:
python app.py
Now, you can access the Ping endpoint by visiting http://localhost:5000/ping in your browser or using a tool like Postman.
Conclusion
Congratulations! You have successfully created a Ping endpoint using Flask. This is just the beginning of building a REST API with Flask. Stay tuned for more tutorials on building endpoints, handling requests, and working with databases in Flask.
I wish you made a course teaching this, it would be really helpful if you did it since you already really good at explaining, wish you luck
