app_2.py

# -*- coding:utf-8 -*-
from app import create_app

# 创建

from flask import Flask

def create_app():

    app.config.from_object('config')
    # 蓝图注册
    register_blueprint(app)

    return app


# 蓝图注册

    # 注册 api
    from app.api.goods import api

    # 注册 web
    from app.web.goods import web
    app.register_blueprint(web)

pro_dir/app/web/goods.py

from flask import jsonify, Blueprint

# 实例化蓝图对象

        'milk': 5.6
    }

    return jsonify(result)
