Question

我对Flask较陌生，并且尝试在终端中运行代码时运行该应用程序，但收到以下消息：

404 Not Found 
The requested URL was not found on the server. If you entered the URL 
manually please check your spelling and try again.

这是我的app.py文件：

from flask import Flask
from flask_mongoengine import MongoEngine
from flask_sslify import SSLify
import os


app = Flask(__name__)
app.url_map.strict_slashes = False
app.config.from_object('config')
db = MongoEngine(app)

这是我的views.py文件：

from flask import Flask, request, render_template, flash, redirect, 
session, url_for, g, jsonify, make_response


@app.before_request
def before_request():
    g.user = current_user


@app.errorhandler(404)
def not_found_error(error):
    return render_template('404.html'), 404


@app.errorhandler(500)
def internal_error(error):
    return render_template('500.html'), 500


@app.route('/index', methods=['GET', 'POST'])
def index():
    if not session.get('user_id'):
        return redirect(url_for('login'))
    user = User.objects.get(id=session.get('user_id'))
    return render_template('frontpage.html', user=user)

@app.route('/')             
def root():
    return redirect(url_for('index'))


if __name__ == "__main__":
    app.run(debug=True)

这是我的models.py文件：

from flask_mongoengine.wtf import model_form
from mongoengine import Document, StringField, EmailField, 
ReferenceField, IntField, DateTimeField, \
BooleanField, DictField, ListField, EmbeddedDocument, \
EmbeddedDocumentListField, FloatField, FileField

from flask import request
from hashlib import md5
from app import db

class User(Document):
    email = StringField(required=True, unique=True)
    username = StringField(required=True, max_length=50, unique=True)
    password = StringField(required=True)
    aboutme = StringField()
    photo = FileField()

    created_at = DateTimeField()

    password_reset_token = StringField()

    user_type = StringField()  
    is_admin = BooleanField()
    is_logged_in = BooleanField()

    def is_active(self):

        return True

    def get_id(self):
        return self.email

    def is_authenticated(self):
        return self.authenticated

    def is_anonymous(self):
        return False

这是我的base.html

        {% include 'flash.html' %}
      {% block content %}{% endblock %}
    </div>
  </div>
</div>  

</body>
</html>

最后是我的frontpage.html：

{% extends "base.html" %}

{% block content %}

<h6> Welcome to my site! </h6>


{% endblock %}

我们将不胜感激！
