Here is a simple "Hello, world" example app: .. testcode:: import asyncio import tornado class MainHandler(tornado.web.RequestHandler): def get(self): self.write("Hello, world") async def main(): application = tornado.web.Application([ (r"/", MainHandler), ]) application.listen(8888) await asyncio.Event().wait() if __name__ == "__main__": asyncio.run(main()) .. testoutput:: :hide: See the :doc:`guide` for additional information. Thread-safety notes ------------------- In general, methods on `RequestHandler` and elsewhere in Tornado are not thread-safe. In particular, methods such as `~RequestHandler.write()`, `~RequestHandler.finish()`, and `~RequestHandler.flush()` must only be called from the main thread. If you use multiple threads it is important to use `.IOLoop.add_callback` to transfer control back to the main thread before finishing the request, or to limit your use of other threads to `.IOLoop.run_in_executor` and ensure that your callbacks running in the executor do not refer to Tornado objects.

Instances of this class are callable and can be passed directly to HTTPServer to serve the application:: application = web.Application([ (r"/", MainPageHandler), ]) http_server = httpserver.HTTPServer(application) http_server.listen(8080) The constructor for this class takes in a list of `~.routing.Rule` objects or tuples of values corresponding to the arguments of `~.routing.Rule` constructor: ``(matcher, target, [target_kwargs], [name])``, the values in square brackets being optional. The default matcher is `~.routing.PathMatches`, so ``(regexp, target)`` tuples can also be used instead of ``(PathMatches(regexp), target)``. A common routing target is a `RequestHandler` subclass, but you can also use lists of rules as a target, which create a nested routing configuration:: application = web.Application([ (HostMatches("example.com"), [ (r"/", MainPageHandler), (r"/feed", FeedHandler), ]), ]) In addition to this you can use nested `~.routing.Router` instances, `~.httputil.HTTPMessageDelegate` subclasses and callables as routing targets (see `~.routing` module docs for more information). When we receive requests, we iterate over the list in order and instantiate an instance of the first request class whose regexp matches the request path. The request class can be specified as either a class object or a (fully-qualified) name. A dictionary may be passed as the third element (``target_kwargs``) of the tuple, which will be used as keyword arguments to the handler's constructor and `~RequestHandler.initialize` method. This pattern is used for the `StaticFileHandler` in this example (note that a `StaticFileHandler` can be installed automatically with the static_path setting described below):: application = web.Application([ (r"/static/(.*)", web.StaticFileHandler, {"path": "/var/www"}), ]) We support virtual hosts with the `add_handlers` method, which takes in a host regular expression as the first argument:: application.add_handlers(r"www\.myhost\.com", [ (r"/article/([0-9]+)", ArticleHandler), ]) If there's no match for the current request's host, then ``default_host`` parameter value is matched against host regular expressions. .. warning:: Applications that do not use TLS may be vulnerable to :ref:`DNS rebinding ` attacks. This attack is especially relevant to applications that only listen on ``127.0.0.1`` or other private networks. Appropriate host patterns must be used (instead of the default of ``r'.*'``) to prevent this risk. The ``default_host`` argument must not be used in applications that may be vulnerable to DNS rebinding. You can serve static files by sending the ``static_path`` setting as a keyword argument. We will serve those files from the ``/static/`` URI (this is configurable with the ``static_url_prefix`` setting), and we will serve ``/favicon.ico`` and ``/robots.txt`` from the same directory. A custom subclass of `StaticFileHandler` can be specified with the ``static_handler_class`` setting. .. versionchanged:: 4.5 Integration with the new `tornado.routing` module.

When `Finish` is raised in a `RequestHandler`, the request will end (calling `RequestHandler.finish` if it hasn't already been called), but the error-handling methods (including `RequestHandler.write_error`) will not be called. If `Finish()` was created with no arguments, the pending response will be sent as-is. If `Finish()` was given an argument, that argument will be passed to `RequestHandler.finish()`. This can be a more convenient way to implement custom error pages than overriding ``write_error`` (especially in library code):: if self.current_user is None: self.set_status(401) self.set_header('WWW-Authenticate', 'Basic realm="something"') raise Finish() .. versionchanged:: 4.3 Arguments passed to ``Finish()`` will be passed on to `RequestHandler.finish`. r4N)r5r6r7r8rr9r4r:r;rr s 0 r:rc8^\rSrSrSrS\SS4U4SjjrSrU=r$)ri zException raised by `RequestHandler.get_argument`.

You should provide the keyword argument ``url`` to the handler, e.g.:: application = web.Application([ (r"/oldpath", web.RedirectHandler, {"url": "/newpath"}), ]) `RedirectHandler` supports regular expression substitutions. E.g., to swap the first and second parts of a path while preserving the remainder:: application = web.Application([ (r"/(.*?)/(.*?)/(.*)", web.RedirectHandler, {"url": "/{1}/{0}/{2}"}), ]) The final URL is formatted with `str.format` and the substrings that match the capturing groups. In the above example, a request to "/a/b/c" would be formatted like:: str.format("/{1}/{0}/{2}", "a", "b", "c") # -> "/b/a/c" Use Python's :ref:`format string syntax ` to customize how values are substituted. .. versionchanged:: 4.5 Added support for substitutions into the destination URL. .. versionchanged:: 5.0 If any query arguments are present, they will be copied to the destination URL. rr@rJNcXlX lgrM)_url _permanent)rRrr@s r;rfRedirectHandler.initialize1 s  #r:rqrIc4URR"U0UD6nURR(aH[R "U[ [R"URR555nURX0RS9 g)Nr) rrrHrr url_concatrK qs_to_qslrFr)rRrqrIto_urls r;rRedirectHandler.get5 sl!!4262 << ' '((X'' (D(DEFF f 8r:)rrr) r5r6r7r8rrrrfr rr9r4r:r;rr s<@$c$d$d$9999r:rc \rSrSrSrSr0r\R"5r S*S\ S\ \ SS4Sjjr \ S+S j5rS\ S\S4S jrS,S\ S \SS4S jjrS\ \ 4S jrS+SjrS\4Sjr\ S\ S\ S\ 4Sj5rS\ S\ S\ \ 4Sjr\ S-S\ S\ \S\ \S\\SS44Sjj5r\ S\ S\ 4Sj5rS\R<4SjrS\4Sjr S\ \!RB4Sjr"S\ 4Sjr#S\ SS4Sjr$S\ S\ \!RBS\ S\4S jr%\ S,S!\&\ \'4S\ S"\S\ 4S#jj5r(S$\ S\ 4S%jr)\ S!\&\ \'4S\ S\ \ 4S&j5r*\ S'\ S\ \ 4S(j5r+S)r,g).rMi@ a A simple handler that can serve static content from a directory. A `StaticFileHandler` is configured automatically if you pass the ``static_path`` keyword argument to `Application`. This handler can be customized with the ``static_url_prefix``, ``static_handler_class``, and ``static_handler_args`` settings. To map an additional path to this handler for a static data directory you would add a line to your application like:: application = web.Application([ (r"/content/(.*)", web.StaticFileHandler, {"path": "/var/www"}), ]) The handler constructor requires a ``path`` argument, which specifies the local root directory of the content to be served. Note that a capture group in the regex is required to parse the value for the ``path`` argument to the get() method (different than the constructor argument above); see `URLSpec` for details. To serve a file like ``index.html`` automatically when a directory is requested, set ``static_handler_args=dict(default_filename="index.html")`` in your application settings, or add ``default_filename`` as an initializer argument for your ``StaticFileHandler``. To maximize the effectiveness of browser caching, this class supports versioned urls (by default using the argument ``?v=``). If a version is given, we instruct the browser to cache this file indefinitely. `make_static_url` (also available as `RequestHandler.static_url`) can be used to construct a versioned url. This handler is intended primarily for use in development and light-duty file serving; for heavy traffic it will be more efficient to use a dedicated static file server (such as nginx or Apache). We support the HTTP ``Accept-Ranges`` mechanism to return partial content (because some browsers require this functionality to be present to seek in HTML5 audio or video). **Subclassing notes** This class is designed to be extensible by subclassing, but because of the way static urls are generated with class methods rather than instance methods, the inheritance patterns are somewhat unusual. Be sure to use the ``@classmethod`` decorator when overriding a class method. Instance methods may use the attributes ``self.path`` ``self.absolute_path``, and ``self.modified``. Subclasses should only override methods discussed in this section; overriding other methods is error-prone. Overriding ``StaticFileHandler.get`` is particularly problematic due to the tight coupling with ``compute_etag`` and other methods. To change the way static urls are generated (e.g. to match the behavior of another server or CDN), override `make_static_url`, `parse_url_path`, `get_cache_time`, and/or `get_version`. To replace all interaction with the filesystem (e.g. to serve static content from a database), override `get_content`, `get_content_size`, `get_modified_time`, `get_absolute_path`, and `validate_absolute_path`. .. versionchanged:: 3.1 Many of the methods for subclasses were added in Tornado 3.1. iNr default_filenamerJcXlX lgrM)rootr)rRr rs r;rfStaticFileHandler.initialize s  0r:c^UR 0UlSSS5 g!,(df  g=frM)_lock_static_hashesrs r;roStaticFileHandler.reset s YY!#C YYs ,c"URUSS9$)NF) include_body)rrRr s r;rStaticFileHandler.head sxx5x11r:rcn# URU5UlAURURUR5nUR URU5UlUR cgUR 5UlUR5 UR5(aURS5 gSnURRRS5nU(a[R"U5nUR!5nU(aUupxUbUS:a Xv- nUS:aSnUb Xv:dUbXx:dUS:Xa:URS5 UR#SS5 UR#SSU<35 gUbX:aUnXh=(d UU=(d S- :wa8URS 5 UR#S[R$"XxU55 OS=pxUbUbX- n OUbUn O UbXg- n OUn UR#S U 5 U(ahUR'UR Xx5n [)U [*5(aU /n U H-n UR-U 5 UR/5IShvN M/ gURR4S :XdegN&![0R2a  gf=f7f) NrRangerirrz Content-Rangezbytes */rr@)parse_url_pathr get_absolute_pathrvalidate_absolute_path absolute_pathget_modified_timemodified set_headersshould_return_304rrHrrr _parse_request_rangeget_content_sizer_get_content_range get_contentrrrNrr rr) rRr rr request_range range_headersizerendrcontentrHs r;rStaticFileHandler.get sp''- ..tyy$))D !88MR    % ..0    ! ! # # OOC  ||++//8 %99,GM$$& &JE UQY 19E!]s5<$ =1GH3:  t 33$#X%@%@T%R E   [N _ N  !\N!N (.9 &&t'9'95FG'5))") JJu%**,&&!<<&&&0 00 '11s<I J5 $J1J2J6"J5JJ2.J51J22J5ctURceURUR5nU(dgSU<S3$)zSets the ``Etag`` header based on static url version.

If the user is not logged in, they will be redirected to the configured `login url `. If you configure a login url with a query parameter, Tornado will assume you know what you're doing and use it as-is. If not, it will add a `next` parameter so the login page knows where to send you once you're logged in. rRrJNc>UR(dURRS;aUR5nSU;a[R R U5R(aURR5nO/URRceURRnUS[[US95-- nURU5 g[S5eT"U/UQ70UD6$)Nrr)nextrA)rrHrrurllibparseurlsplitschemefull_urlrrr2rFrt)rRrqrIrnext_urlrs r;rauthenticated..wrapper s  ||""o5((*c>||,,S188#'<<#8#8#:#||//;;;#'<<#3#334X+>!???C c"C. d,T,V,,r:rrs` r; authenticatedr@ s@__V-- )D/ "--& Nr:c\rSrSrSrS\SS4Sjr\S\4Sj5r S\S \S\ 4S jr S\ \ 4S jr S\ \\ 4S jrS\ \ 4S jrS\ \\ 4SjrS\ \ 4SjrS\ \ 4SjrS\ S \S\4SjrSrg)ri aA re-usable, modular UI unit on a page.

Templates rendered through this module also get access to UIModule's automatic JavaScript/CSS features. Simply call set_resources inside the template and give it keyword arguments corresponding to the methods on UIModule: {{ set_resources(js_files=static_url("my.js")) }} Note that these resources are output once per template file, not once per instantiation of the template, so they must not depend on any arguments to the template. rrJNc@>[TU]U5 /Ul0UlgrM)rWrX_resource_list_resource_dict)rRrrgs r;rXTemplateModule.__init__` s  !  r:r rIc N^^S[4UU4SjjnTR"T4SU0UD6$)NrJc>TTR;a+TRRU5 UTRT'gTRTU:wa [S5eg)NzCset_resources called with different resources for the same templater")rcrbrr)rIr rRs r; set_resources,TemplateModule.render..set_resourcesg sf4...##**62,2##D) &&t,6$:r:rg)rrT)rRr rIrgs`` r;ruTemplateModule.renderf s1 s  !!$NmNvNNr:rc0^U4SjUR5$)Nc3>># UHnTU;dM UTv M g7frMr4)rOrrs r;rS0TemplateModule._get_resources..v s@ 31sax# 3s  )rbrRrs `r;_get_resourcesTemplateModule._get_resourcesu s@ 3 3@@r:cBSRURS55$)N rVrcrorjs r;rV"TemplateModule.embedded_javascriptx syy,,-BCDDr:c/nURS5HBn[U[[45(aUR U5 M1UR U5 MD U$)NrWrorrrrrXrRr~rms r;rWTemplateModule.javascript_files{ sN$$%78A!lE233 a  a 9  r:cBSRURS55$)NrrrYrsrjs r;rYTemplateModule.embedded_css syy,,^<==r:c/nURS5HBn[U[[45(aUR U5 M1UR U5 MD U$)NrZrvrws r;rZTemplateModule.css_files sM$$[1A!lE233 a  a 2  r:cBSRURS55$)Nr"r[rsrjs r;r[TemplateModule.html_head wwt**;788r:cBSRURS55$)Nr"r\rsrjs r;r\TemplateModule.html_body rr:)rcrb)r5r6r7r8rr=rXrr rrur'rorVrWrYrZr[r\r9rrs@r;r r P s !!4!
