Use flask as the development framework, must be modular according to function, otherwise, the larger the project later, the development speed is slower.
1,FlaskModular Structure Planning
[[email protected] yangyun]# tree.├── asset #资产功能目录 │ ├── __init__.py│ ├── models.py #资产数据库结构文件 │ └── views.py #资产视图文件 ├── user #用户功能目录 │ ├──__init__.py│ ├── models.py #用户数据库结构文件 │ └── views.py #用户视图配置文件 ├── config.py #公共配置文件 ├── requirements.txt #需要的安装包 ├── run.py #主运行文件 ├── static #静态文件目录, css,js, image et └── templates #静态页面存放目录 ├── asset #asset功能模块页面存放目录 │ └── index.html ├── index.html #首页 └── user └── index.html
2,run.pyMaster Run File configuration
[email protected] yangyun]# cat run.py
from flask import flaskfrom asset import assetfrom user import user apple=flask (__name__, template_folder= ' templates ', #指定模板路径, can be a relative path, or it can be an absolute path. static_folder= ' static ', #指定静态文件前缀, default static file path prefix #static_url_path = '/opt/auras/static ', #指定静态文件存放路径. ) apple.register_blueprint (asset,url_prefix= '/asset ') #注册asset蓝图 and specify a prefix. Apple.register_blueprint (user) #注册user蓝图, no prefix specified. if __name__== ' __main__ ': apple.run (host= ' 0.0.0.0 ', port=8000,debug=true) #运行flask http program, host specifies the listener ip,port the specified listening port, debug mode needs to be turned on.
3,AssetFunction Module Configuration
Similar configuration for other function modules
1) __init__.py file Configuration
[email protected] asset]# cat __init__.py
From flask import Blueprint asset=blueprint (' Asset ', __name__, #template_folder = '/opt/auras/templates/', # Specify template path #static_folder = '/opt/auras/flask_bootstrap/static/', #指定静态文件路径) import views
2) views.py file Configuration
[email protected] asset]# cat views.py
From flask import render_templatefrom Asset import Asset @asset. Route ('/') #指定路由为/, because the prefix specified in run.py, when the browser accesses, the path is Http://IP/asset/def index (): print ' __name__ ', __name__ returnrender_template (' Asse T/index.html ') #返回index. html template, path default under Templates
3) Front-end page configuration
[Email protected] yangyun]# echo ' This isasset index page ... ' >templates/asset/index.html
4,UserFunction Module Configuration
The configuration here is consistent with the above asset configuration
1) __init__.py configuration
[email protected] yangyun]# cat user/__init__.py
From flask import blueprintuser=blueprint (' user ', __name__,) import views
2) views.py configuration
[email protected] yangyun]# cat user/views.py
From flask import render_templatefrom user Import user @user. Route ('/') def index (): print ' __name__ ', __name__ Returnrender_template (' user/index.html ')
3) static page configuration
Echo ' This is User page .... ' >templates/user/index.html
5,Requirements.txtFile Configuration
The primary role is to record the required dependency packages, and the new environment is deployed with the following dependencies installed,pip installation command : pip install-r requirements.txt
[Email protected] yangyun]# catrequirements.txtflask==0.10.1flask-bootstrap==3.3.5.6flask-login== 0.2.11flask-sqlalchemy==2.0flask-wtf==0.12
6, browser access testing
Back-End Run program
[[email protected] yangyun]# python run.py *running on http://0.0.0.0:8000/(press CTRL + C to quit) *restarting with stat
front-end access to asset page

front-end access to user page

Why does 404 appear ? Because there is no prefix specified in the run.py, user is not required in the URL.
