Flask实践——microblog 环境搭建 & helloword (1)-优快云博客

本文介绍如何从零开始搭建Flask应用环境，并通过创建第一个项目“Hello, World!”来验证环境配置是否正确。文章详细说明了创建项目目录、安装依赖包、设置虚拟环境、构建项目框架等步骤。

环境搭建 & helloword

创建项目目录，进入该目录
```
mkdir microblog
cd microblog
```
使用virtualen创建独立的运行环境
```
virtualenv -p /usr/bin/python3 flask
```
进入环境
```
source flask/bin/activate
```

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

构建Flask项目框架

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

创建app/__init__.py

from flask import Flask

app = Flask(__name__)
from app import views

创建app/views.py

from app import app

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

创建microblog/run.py

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

运行run.py
```
http://localhost:5000
```
