자바의 서블렛 --------파이썬의 플라스크...django(웹 프레임웤?)

rmi..이용한게 ejb

뭔가 만들었는데 웹으로 ㅁ보여주고싶을때! 간단하게 쓰는 Flask

from flask import Flask
app = Flask(__name__)

@app.route("/")
def hello():
    return "Hello World!"

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

파라미터 받기

from flask import Flask, request
app = Flask(__name__)

@app.route("/param")
def param():
    temp1 = request.args.get('num1')
    temp2 = request.args.get('num2')
    return temp1 + ","+ temp2


if __name__ == "__main__":
    app.run(port=80)

get 안에 두번째 인수로 넣어주는건 그 값이 안왔을떄의 기본값임

from flask import Flask, request
from flask.templating import render_template
app = Flask(__name__)

@app.route("/test")
def test():
    return render_template('param.html')


@app.route("/post",methods=['POST'])
def post():
#     temp1 = request.args.get('num1',"num1")
#     temp2 = request.args.get('num2',"num2")
    temp1 = request.form['num1']
    temp2 = request.form['num2']
    return "num1 : "+temp1 + ", num2 : "+ temp2


if __name__ == "__main__":
    app.run(port=80)
