簡單的一階程度拆分：

注解：Manager啟動會導入create_app，導入會進行創建初始化app，初始化時會導入views,回到init內部，返回manage.py
manage.py代碼：
from flask_script import Manager
from App import create_app
app = create_app()
manager = Manager(app=app)
if __name__ == '__main__':
manager.run()
App/views.py代碼：
def init_route(app):
@app.route('/')
def hello_world():
return 'Hello World!'
@app.route('/hello/')
def hello():
return '1111!'
App/__init__.py代碼：
from flask import Flask
from App.views import init_route
def create_app():
app = Flask(__name__)
init_route(app)
return app
藍圖flask-blueprint(Demo):
App/manage.py代碼：
from flask_script import Manager
from App import create_app
app = create_app()
manager = Manager(app=app)
if __name__ == '__main__':
manager.run()
App/__init__.py代碼：
from flask import Flask
from App.views import blue, second, init_view
def create_app():
app = Flask(__name__)
#app.register_blueprint(blue)
#app.register_blueprint(second)
#初始化view,傳遞app
init_view(app=app)
return app
views轉換為包的形勢→ 類名右鍵→ Refactor→ Convert to Python Package
App/views/__init__.py代碼：
from App.views.fours_blue import fours
from .first_blue import blue
from .second_blue import second
def init_view(app):
app.register_blueprint(blue)
app.register_blueprint(second)
app.register_blueprint(fours)
App/views/first_blue.py代碼：
from flask import app, Blueprint
blue = Blueprint('blue', __name__)
@blue.route('/')
def index():
return '我是藍圖的主頁'
App/views/second_blue.py代碼：
from flask import Blueprint
second = Blueprint('second', __name__)
@second.route('/hello/')
def hello():
return 'Second Blue'
