3. Abount flask
• A microframework for python
– 很有彈性
• run independently or run as an apache module
• 姐妹framework: bottle

4. MVC

5. 產生app物件
• DocRoot/myapp/__init__.py
– From flask import Flask
– app = Flask(__name__)
– Import views
• DocRoot/runserver.py
– From myapp import app
– app.run(debug=True)

6. Controller: Rounting(I)
• 官方建議放在:DocRoot/myapp/views.py
• App要import views
• Views也要import app

7. Controller: Routing (II)
• url route到函數 (decorator特性)
• 可自動過濾url形態、post、get方法
• Return 對應的html

8. Model
• 沒有明確的規範
• 可自行把Model從controller裡切開

9. Jinja2: View(I)
• Template的根目錄放在: DocRootmyapptemplates
• Return render_template(“xxx.dhtml”,
arg1=xxx,arg2=xxx, **other_arg_dict)

10. Jinja2: View(II)
• Can pass python variable to template
• Render data in a python-like way
• Auto XSS escape
• Include v.s. extend
– Can Inc/Ext variables: Dependency injection

11. Other static files
• e.g. 圖檔、css、js 全部放在 DocRoot/myapp/static/
