如何在apache中使用datetime.date值？

# myapp.py

import datetime

def get_date():
    now = datetime.date.today()
    return now.strftime("%Y-%m-%d")

def application(environ, start_response):
    start_response('200 OK', [('Content-Type', 'text/html')])
    date = get_date()
    return [b"<h1>Today's date is:</h1>", bytes(date, 'utf-8')]

<VirtualHost *:80>
    ServerName example.com
    DocumentRoot /path/to/myapp

    WSGIDaemonProcess myapp processes=2 threads=15 display-name=%{GROUP}
    WSGIProcessGroup myapp
    WSGIScriptAlias / /path/to/myapp/myapp.wsgi

    <Directory /path/to/myapp>
        Require all granted
    </Directory>
</VirtualHost>
