Python程式設計：web架構flask、web.py、tornado最小應用

Flask

http://docs.jinkan.org/docs/flask/

pip install Flask      

最小應用

from flask import Flask

app = Flask(__name__)

@app.route('/')
def hello_world():
    return 'Hello World!'

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

web.py

http://webpy.org/

pip install web.py      

import web

urls = (
    '/', 'index'
)

class index:
    def GET(self):
        return "Hello, world!"

if __name__ == "__main__":
    app = web.application(urls, globals())
    app.run()      

tornado

http://www.tornadoweb.org/en/stable/

pip install tornado      

from tornado.web import Application
from tornado.web import RequestHandler
from tornado.ioloop import IOLoop


class IndexHandler(RequestHandler):
    def get(self):
        self.write("hello world")


handlers = [
    ("/", IndexHandler),
]

if __name__ == '__main__':
    app = Application(handlers)
    app.listen(8080)  # http://localhost:8080/
    IOLoop.current().start()
      

總結：

三個web架構，基本相似，都是：
