如何在蓝图中引用Flask应用程序工厂中的其他模块？

from flask import Blueprint

blueprint = Blueprint('my_blueprint', __name__)

@blueprint.route('/')
def index():
    return 'Hello, World!'

from flask import Flask

def create_app():
    app = Flask(__name__)
    app.register_blueprint(blueprint)
    return app

from my_app import create_app

app = create_app()

# 使用蓝图中的路由和视图函数
@app.route('/')
def index():
    return 'Hello, World!'

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