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

错误案例
from flask import Flask app = Flask(__name__) @app.route('/hello.world') def check(): return 200 if __name__ == '__main__': app.run(debug=False, host='0.0.0.0', port=80)
注：返回值不可为整数
变量规则
from flask import Flask app = Flask(__name__) @app.route('/h/<user>') def check(user): return "hello world: %s" % user if __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:', msg else: msg = request.args.get('msg') return 'put msg:', msg if __name__ == '__main__': app.run(debug=False, host='0.0.0.0', port=8099)
