簡單入手

import tornado.ioloop
import tornado.web
class MainHandler(tornado.web.RequestHandler):
    def get(self):
        self.write("Hello, world")
application = tornado.web.Application([
    (r
 
"/index", MainHandler),
])
if __name__ == "__main__":
    application.listen(8888)
    tornado.ioloop.IOLoop.instance().start()

import tornado.ioloop
import tornado.web
from tornado import httpclient
from tornado.web import asynchronous
from tornado import gen
# import uimodules as md
 

# import uimethods as mt
class MainHandler(tornado.web.RequestHandler):
        @asynchronous
        @gen.coroutine              #沒測出來效果(這兩個裝飾器)
        def get(self):
            print(‘start get ‘)
            http = httpclient.AsyncHTTPClient()
            http.fetch("https://www.google.com/
 
", self.callback) #利用fetch發送一個異步請求(掛起)
            self.write(‘end‘)
        def callback(self, response):
            print(response.body,"---")
settings = {
    ‘template_path‘: ‘template‘,
    ‘static_path‘: ‘static‘,
    ‘static_url_prefix‘: ‘/static/‘,
    # ‘ui_methods‘: mt,
    # ‘ui_modules‘: md,
}
application = tornado.web.Application([
    (r"/index", MainHandler),
], **settings)

if __name__ == "__main__":
    application.listen(8009)
    tornado.ioloop.IOLoop.instance().start()

配置靜態路徑

settings = {
    ‘template_path‘: ‘template‘,
    ‘static_path‘: ‘static‘,
    ‘static_url_prefix‘: ‘/static/‘,
}
