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
请求
$curl http://10.177.80.30:80/hello.world
hello world!
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=)
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)
