How do I implement OAuth in a Flask application?

To implement OAuth in Flask, you can use the Flask-Dance library. It simplifies the process of integrating OAuth providers.

What are the steps to set up Flask-Dance?

First, install Flask-Dance using pip. Then, create a Flask app and configure the OAuth blueprint for your provider.

Can you give me an example of the code?

Sure! Here's a basic example:

from flask import Flask
from flask_dance.contrib.google import make_google_blueprint, google

app = Flask(__name__)
app.secret_key = 'your_secret_key'

google_bp = make_google_blueprint(client_id='your_client_id', client_secret='your_client_secret', redirect_to='google_login')
app.register_blueprint(google_bp, url_prefix='/google_login')

@app.route('/')
def index():
    return 'Welcome!'

if __name__ == '__main__':
    app.run()

What if I want to use a different OAuth provider?

You can use Flask-Dance with various providers like GitHub, Facebook, or Twitter. Just follow the specific setup for each provider.
