安装
pip install Flask
入门例子
from flask import Flask app = Flask(__name__)@app.route('/hello.world') def check():return 'hello world!'if __name__ == '__main__':app.run(debug=False, host='0.0.0.0', port=80) #指定了费debug模式，外部可访问的服务器，端口

$curl http://10.177.80.30:80/hello.world
hello world!错误案例
from flask import Flaskapp = Flask(__name__)@app.route('/hello.world') def check():return 200if __name__ == '__main__':app.run(debug=False, host='0.0.0.0', port=80)

变量规则
from flask import Flask app = Flask(__name__)@app.route('/h/') def check(user):return "hello world: %s" % userif __name__ == '__main__':app.run(debug=False, host='0.0.0.0', port=801)
请求：
$curl http://10.125.8.116:801/h/lalala hello world: lalala
输出PUT、POST请求中的参数
from flask import Flask from flask import request import os app = Flask(__name__)@app.route('/testcase', methods=['GET', 'POST']) def test():if request.method == 'POST':msg = request.form.get('msg')return 'post msg:', msgelse:msg = request.args.get('msg')return 'put msg:', msgif __name__ == '__main__':app.run(debug=False, host='0.0.0.0', port=8099)
