我在Apache2上运行了一个静态网站。我在网站上有一个表单，我想将表单的内容传递给Flask应用程序。现在我只得到错误404时，试图将数据传递到应用程序，但静态部分的网站工作正常。我将其配置如下：
000-default.conf

<VirtualHost *:443>
    # The ServerName directive sets the request scheme, hostname and port that
    # the server uses to identify itself. This is used when creating
    # redirection URLs. In the context of virtual hosts, the ServerName
    # specifies what hostname must appear in the request's Host: header to
    # match this virtual host. For the default virtual host (this file) this
    # value is not decisive as it is used as a last resort host regardless.
    # However, you must set it for any further virtual host explicitly.
    ServerAdmin webmaster@localhost
    DocumentRoot /var/www/html
    # Available loglevels: trace8, ..., trace1, debug, info, notice, warn,
    # error, crit, alert, emerg.
    # It is also possible to configure the loglevel for particular
    # modules, e.g.
    #LogLevel info ssl:warn
    ErrorLog ${APACHE_LOG_DIR}/error.log
    CustomLog ${APACHE_LOG_DIR}/access.log combined
    WSGIDaemonProcess mailer user=www-data group=www-data threads=5 home=/var/www/mailer
    WSGIScriptAlias /mailer /var/www/mailer/app.wsgi
    <Directory /var/www/mailer>
            WSGIProcessGroup mailer
            WSGIApplicationGroup %{GLOBAL}
            Require all granted
    </Directory>
    # For most configuration files from conf-available/, which are
    # enabled or disabled at a global level, it is possible to
    # include a line for only one particular virtual host. For example the
    # following line enables the CGI configuration for this host only
    # after it has been globally disabled with "a2disconf".
    #Include conf-available/serve-cgi-bin.conf
RewriteEngine on
RewriteCond %{SERVER_NAME} =alyfit.fi
RewriteRule ^ https://%{SERVER_NAME}%{REQUEST_URI} [END,NE,R=permanent]
</VirtualHost>

我最初有一个单独的.conf用于Flask应用程序，但我在这里读到另一个问题，你不能为两个不同的虚拟主机使用相同的服务器名和端口。
app.wsgi

import logging
import sys
logging.basicConfig(filename='/var/log/apache2/mailer_error.log', level=logging.DEBUG)
sys.path.insert(0, '/var/www/mailer')
sys.path.insert(0, '/var/www/mailer/venv/lib/python3.10/site-packages/')
logging.debug('About to import app...')
from mailer import app as application

mailer.py

from flask import Flask, request, Blueprint
from flask_mail import Mail, Message
import os
app = Flask(__name__)
mailer_bp = Blueprint('mailer', __name__, url_prefix='/mailer')
# Flask-Mail configuration
app.config['MAIL_SERVER'] = 'smtp.redacted.com' 
app.config['MAIL_PORT'] = 1234 
app.config['MAIL_USERNAME'] = os.getenv('MAIL_USERNAME') 
app.config['MAIL_PASSWORD'] = os.getenv('MAIL_PASSWORD') 
app.config['MAIL_USE_TLS'] = True
app.config['MAIL_USE_SSL'] = False
mail = Mail(app)
@mailer_bp.route('/', methods=['POST'])
def receive_data():
    name = request.form.get('name')
    email = request.form.get('email')
    msg = Message('Hello',
                  sender='redacted@redacted.com',
                  recipients=[email])
    msg.body = f'Hello {name}'
    mail.send(msg)
    return 'OK', 200
app.register_blueprint(mailer_bp)
if __name__ == '__main__':
    app.run()

我已经尝试了这么多不同的配置，似乎没有什么使它工作。邮件日志上没有写任何东西，Apache日志也没有给予任何信息。我已验证是否安装了所有必要的库。我经历了20个类似的stackoverflow问题，没有一个解决方案有效。
