login por https
Del ejemplo de flaskr. Uso de url_for:
url_for('<destino>', _external=True, _scheme='http|https'))
@app.route('/login', methods=['GET', 'POST']) def login(): if not request.is_secure: return redirect(url_for('login', _external=True, _scheme='https')) error = None if request.method == 'POST': if request.form['username'] != app.config['USERNAME']: error = 'Invalid username' elif request.form['password'] != app.config['PASSWORD']: error = 'Invalid password' else: session['logged_in'] = True flash('You were logged in') return redirect(url_for('show_entries', _external=True, _scheme='http')) return render_template('login.html', error=error)
