3、flask服务 -- 蓝图模块化

flask服务 --蓝图进一步模块化：

注意： 路由函数名称在同一蓝图下不可以相同，不同模块下也不可以

Script Demo:

config.py

# -*- coding:utf-8 -*-

# 一般大写
DEBUG = True

app_3.py

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

app = create_app()


if __name__ == '__main__':
    app.run(host='0.0.0.0', port=5001)

proj_dir/app/__init__.py

# -*- coding:utf-8 -*-
from flask import Flask

def create_app():
    app = Flask(__name__)
    app.config.from_object('config')
    # 蓝图注册
    register_blueprint(app)

    return app


# 蓝图注册
def register_blueprint(app):
    # 注册 api
    from app.api import api
    app.register_blueprint(api)

proj_dir/app/api/__init__.py

# -*- coding:utf-8 -*-
from flask import Blueprint

'''
函数名称在同一蓝图下不能相同，跨模块也不可以
'''

# 实例化蓝图对象
api = Blueprint('api', __name__)
# 导入 
from app.api import goods, user

proj_dir/app/api/goods.py

# -*- coding:utf-8 -*-
from flask import jsonify
from . import api


@api.route('/api/getgoods')
def get_goods():
    result = {
        'computer': 16800,
        'milk': 29.6
    }

    return jsonify(result)


@api.route('/api/getgoods2')
def get_goods2():
    result = {
        'computer': 16800,
        'watermelon': 99.9
    }

    return jsonify(result)

proj_dir/app/api/user.py

# -*- coding:utf-8 -*-
from flask import jsonify
from . import api


@api.route('/api/getusers')
def get_users():
    result = {
        'host': '0.0.0.0',
        'password': '123456'
    }

    return jsonify(result)


@api.route('/api/getusers2')
def get_users2():
    result = {
        'host': '0.0.0.1',
        'password': 'qwerty'
    }

    return jsonify(result)
