安装

pip install Flask

 

入门例子

from flask import Flaskapp = 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.worldhello 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)

注：返回值不可为整数

变量规则

from flask import Flaskapp = 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/lalalahello world: lalala

输出PUT、POST请求中的参数

from flask import Flaskfrom flask import requestimport osapp = 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:', msgif __name__ == '__main__':    app.run(debug=False, host='0.0.0.0', port=8099)
