本篇博客主要记录python3.6使用flask开发。代码托管：https://gitee.com/liwl1991/my-flask

1. pip3配置国内源

终端执行：pip3 config set global.index-url https://mirrors.aliyun.com/pypi/simple

查看：pip3 config list

2. 安装flask环境

终端执行：pip3 install flask

3. 创建app.py

from flask import Flask

app = Flask(__name__)
app.config['DEBUG'] = True

@app.route('/')
def index():
    return "hello,world"

if __name__ == "__main__":
	app.run()

4. 运行app.py

终端执行：python3 app.py

浏览器访问：http://127.0.0.1:5000/

5. url传参访问

from flask import Flask

app = Flask(__name__)
app.config['DEBUG'] = True

@app.route('/')
def index():
    return "hello,world"

@app.route('/user/<name>')
def user(name):
    return f"hello,{name}"

if __name__ == "__main__":
	app.run()
