如何在flask中将数据从一个页面路由到另一个页面？

from flask import Flask, request, redirect, url_for

app = Flask(__name__)

@app.route('/input', methods=['GET', 'POST'])
def input_data():
    if request.method == 'POST':
        data = request.form['data']
        return redirect(url_for('display_data', data=data))
    return '''
        <form method="post" action="/input">
            <input type="text" name="data">
            <input type="submit" value="Submit">
        </form>
    '''

@app.route('/display')
def display_data():
    data = request.args.get('data')
    return f'The data is: {data}'

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