Flask

Managing session data in Flask

Flask tip:

Setting a value to Flask's session is as simple as:

session['key'] = 'value'

For example:

from flask import Flask, redirect, request, session, url_for

# Create the Flask application
app = Flask(__name__)

app.secret_key = "BAD SECRET KEY"


@app.route("/set_email", methods=["GET", "POST"])
def set_email():
    if request.method == "POST":
        # Save the form data to the session object
        session["email"] = request.form["email_address"]
        print(session["email"])
        return redirect(url_for("set_email"))
    return """
        <form method="post">
        <label for="email">Enter your email address:</label>
        <input name="email_address" required / >
        <button type="submit">Submit</button
        </form>
        """
