Python Tornado

A force to be reckoned in the web world ... more than an async server, an small micro-framework in itself.

See PythonMicroFramework#Tornado.

Tornado is a Python web framework and asynchronous networking library, originally developed at FriendFeed.

By using non-blocking network I/O, Tornado can scale to tens of thousands of open connections, making it ideal for long polling, WebSockets, and other applications that require a long-lived connection to each user.

Async Client Libraries built on tornado.ioloop

Tornado is noted for its high performance. It tries to solve the C10k problem affecting other servers.

Some Tornado features may require one of the following optional libraries:

unittest2 is needed to run Tornado’s test suite on Python 2.6 (it is unnecessary on more recent versions of Python)
concurrent.futures is the recommended thread pool for use with Tornado and enables the use of tornado.netutil.ThreadedResolver. It is needed only on Python 2; Python 3 includes this package in the standard library.
pycurl is used by the optional tornado.curl_httpclient. Libcurl version 7.18.2 or higher is required; version 7.21.1 or higher is recommended.
Twisted may be used with the classes in tornado.platform.twisted.
pycares is an alternative non-blocking DNS resolver that can be used when threads are not appropriate.
Monotime adds support for a monotonic clock, which improves reliability in environments where clock adjustments are frequent. No longer needed in Python 3.3.

Tornado Sample

Simple Tornado & Mongodb app using authentication


The current version of Motor requires:

CPython 2.6, 2.7, 3.3, or 3.4. PyMongo? 2.8.0 exactly. Tornado 3.1 or later. Greenlet

Greenlets on the Mac !''

Unix, including Mac OS X. Windows is not supported. [ bummer ]

Authentication And Security

The following examples from

Cookies And Secure Cookies

class MainHandler(tornado.web.RequestHandler):
    def get(self):
        if not self.get_secure_cookie("mycookie"):
            self.set_secure_cookie("mycookie", "myvalue")
            self.write("Your cookie was not set yet!")
            self.write("Your cookie was set!")

User Authentication

class MainHandler(BaseHandler):
    def get(self):
        name = tornado.escape.xhtml_escape(self.current_user)
        self.write("Hello, " + name)

settings = {
    "cookie_secret": "__TODO:_GENERATE_YOUR_OWN_RANDOM_VALUE_HERE__",
    "login_url": "/login",
application = tornado.web.Application([
    (r"/", MainHandler),
    (r"/login", LoginHandler),
], **settings)

Third Party Authentication

class GoogleOAuth2LoginHandler(tornado.web.RequestHandler,
    def get(self):
        if self.get_argument('code', False):
            user = yield self.get_authenticated_user(
            # Save the user with e.g. set_secure_cookie
            yield self.authorize_redirect(
                scope=['profile', 'email'],
                extra_params={'approval_prompt': 'auto'})

Cross-Site Request Forgery Protection

settings = {
    "cookie_secret": "__TODO:_GENERATE_YOUR_OWN_RANDOM_VALUE_HERE__",
    "login_url": "/login",
    "xsrf_cookies": True,
application = tornado.web.Application([
    (r"/", MainHandler),
    (r"/login", LoginHandler),
], **settings)

If xsrf_cookies is set, the Tornado web application will set the _xsrf cookie for all users and reject all POST, PUT, and DELETE requests that do not contain a correct _xsrf value. If you turn this setting on, you need to instrument all forms that submit via POST to contain this field. You can do this with the special UIModule xsrf_form_html(), available in all templates:

<form action="/new_message" method="post">
  {% module xsrf_form_html() %}
  <input type="text" name="message"/>
  <input type="submit" value="Post"/>


      <title>{{ title }}</title>
       {% for item in items %}
         <li>{{ escape(item) }}</li>
       {% end %}
class MainHandler(tornado.web.RequestHandler):
    def get(self):
        items = ["Item 1", "Item 2", "Item 3"]
        self.render("template.html", title="My title", items=items)

Control statements more or less map exactly to Python statements. We support if, for, while, and try, all of which are terminated with {% end %}. We also support template inheritance using the extends and block statements, which are described in detail in the documentation for the tornado.template.

Amazingly similar to PythonBottle actually, except for pre-defined widgets in ui-modules.
