Flask实践——microblog 环境搭建 & helloword (1)

环境搭建 & helloword

1. 创建项目目录，进入该目录

   mkdir microblog
   cd microblog

2. 使用virtualen创建独立的运行环境

   virtualenv -p /usr/bin/python3 flask

3. 进入环境

   source flask/bin/activate

4. 安装相关模块及扩展

   $ flask/bin/pip install flask
   $ flask/bin/pip install flask-login
   $ flask/bin/pip install flask-openid
   $ flask/bin/pip install flask-mail
   $ flask/bin/pip install flask-sqlalchemy
   $ flask/bin/pip install sqlalchemy-migrate
   $ flask/bin/pip install flask-whooshalchemy
   $ flask/bin/pip install flask-wtf
   $ flask/bin/pip install flask-babel
   $ flask/bin/pip install guess_language
   $ flask/bin/pip install flipflop
   $ flask/bin/pip install coverage

5. 构建Flask项目框架

   mkdir app
   mkdir app/static
   mkdir app/templates
   mkdir tmp

6. 创建app/__init__.py

   from flask import Flask
   
   app = Flask(__name__)
   from app import views

7. 创建app/views.py

   from app import app
   
   @app.route('/')
   @app.route('/index')
   def index():
       return "Hello, World!"

8. 创建microblog/run.py

   #!flask/bin/python
   from app import app
   app.run(debug = True)

9. 运行run.py

   http://localhost:5000
