Python: Tornado异步web服务器 vs Flask

Tornado实例

import tornado.httpserver
import tornado.ioloop
import tornado.options
import tornado.web
import tornado.httpclient
import tornado.gen
import json

from tornado.options import define, options
define("port", default=8000, help="run on the given port", type=int)

class IndexHandler(tornado.web.RequestHandler):
    @tornado.web.asynchronous
    @tornado.gen.engine
    def get(self):
        body = json.dumps({'phone': '13818617241','passwd':'666666'})
        client = tornado.httpclient.AsyncHTTPClient()
        response = yield tornado.gen.Task(
            client.fetch,
            'http://api.****.com/*****/user/login',#替换有效url
            method='POST',
            body=body,
        )
        self.write(response.body)
        self.finish()

if __name__ == "__main__":
    tornado.options.parse_command_line()
    app = tornado.web.Application(
        handlers=[
            (r"/", IndexHandler)
        ]
    )
    http_server = tornado.httpserver.HTTPServer(app)
    http_server.listen(options.port)
    tornado.ioloop.IOLoop.instance().start()

Flask实例：
需要gevent框架配合

import time
from flask import *
from gevent import monkey
from gevent.pywsgi import WSGIServer

monkey.patch_all()

app = Flask(__name__)
@app.route('/')
def helloworld():
    time.sleep(10)
    return '睡眠10秒才出现'

@app.route('/home')
def hellohome():
    return '异步立刻出现'

if __name__ == '__main__':
    http_server = WSGIServer(('0.0.0.0', 8000), app)
    http_server.serve_forever()
