"""A non-blocking, single-threaded HTTP server.
|
|
|
|
Typical applications have little direct interaction with the `HTTPServer`
|
|
class except to start a server at the beginning of the process
|
|
(and even that is often done indirectly via `tornado.web.Application.listen`).
|
|
|
|
.. versionchanged:: 4.0
|
|
|
|
The ``HTTPRequest`` class that used to live in this module has been moved
|
|
to `tornado.httputil.HTTPServerRequest`. The old name remains as an alias.

r"""A non-blocking, single-threaded HTTP server.
|
|
|
|
A server is defined by a subclass of `.HTTPServerConnectionDelegate`,
|
|
or, for backwards compatibility, a callback that takes an
|
|
`.HTTPServerRequest` as an argument. The delegate is usually a
|
|
`tornado.web.Application`.
|
|
|
|
`HTTPServer` supports keep-alive connections by default
|
|
(automatically for HTTP/1.1, or for HTTP/1.0 when the client
|
|
requests ``Connection: keep-alive``).
|
|
|
|
If ``xheaders`` is ``True``, we support the
|
|
``X-Real-Ip``/``X-Forwarded-For`` and
|
|
``X-Scheme``/``X-Forwarded-Proto`` headers, which override the
|
|
remote IP and URI scheme/protocol for all requests. These headers
|
|
are useful when running Tornado behind a reverse proxy or load
|
|
balancer. The ``protocol`` argument can also be set to ``https``
|
|
if Tornado is run behind an SSL-decoding proxy that does not set one of
|
|
the supported ``xheaders``.
|
|
|
|
To make this server serve SSL traffic, send the ``ssl_options`` dictionary
|
|
argument with the arguments required for the `ssl.wrap_socket` method,
|
|
including ``certfile`` and ``keyfile``. (In Python 3.2+ you can pass
|
|
an `ssl.SSLContext` object instead of a dict)::
|
|
|
|
HTTPServer(applicaton, ssl_options={
|
|
"certfile": os.path.join(data_dir, "mydomain.crt"),
|
|
"keyfile": os.path.join(data_dir, "mydomain.key"),
|
|
})
|
|
|
|
`HTTPServer` initialization follows one of three patterns (the
|
|
initialization methods are defined on `tornado.tcpserver.TCPServer`):
|
|
|
|
1. `~tornado.tcpserver.TCPServer.listen`: simple single-process::
|
|
|
|
server = HTTPServer(app)
|
|
server.listen(8888)
|
|
IOLoop.instance().start()
|
|
|
|
In many cases, `tornado.web.Application.listen` can be used to avoid
|
|
the need to explicitly create the `HTTPServer`.
|
|
|
|
2. `~tornado.tcpserver.TCPServer.bind`/`~tornado.tcpserver.TCPServer.start`:
|
|
simple multi-process::
|
|
|
|
server = HTTPServer(app)
|
|
server.bind(8888)
|
|
server.start(0) # Forks multiple sub-processes
|
|
IOLoop.instance().start()
|
|
|
|
When using this interface, an `.IOLoop` must *not* be passed
|
|
to the `HTTPServer` constructor. `~.TCPServer.start` will always start
|
|
the server on the default singleton `.IOLoop`.
|
|
|
|
3. `~tornado.tcpserver.TCPServer.add_sockets`: advanced multi-process::
|
|
|
|
sockets = tornado.netutil.bind_sockets(8888)
|
|
tornado.process.fork_processes(0)
|
|
server = HTTPServer(app)
|
|
server.add_sockets(sockets)
|
|
IOLoop.instance().start()
|
|
|
|
The `~.TCPServer.add_sockets` interface is more complicated,
|
|
but it can be used with `tornado.process.fork_processes` to
|
|
give you more flexibility in when the fork happens.
|
|
`~.TCPServer.add_sockets` can also be used in single-process
|
|
servers if you want to create your listening sockets in some
|
|
way other than `tornado.netutil.bind_sockets`.
|
|
|
|
.. versionchanged:: 4.0
|
|
Added ``decompress_request``, ``chunk_size``, ``max_header_size``,
|
|
``idle_connection_timeout``, ``body_timeout``, ``max_body_size``
|
|
arguments. Added support for `.HTTPServerConnectionDelegate`
|
|
instances as ``request_callback``.
|
|
|
|
.. versionchanged:: 4.1
|
|
`.HTTPServerConnectionDelegate.start_request` is now called with
|
|
two arguments ``(server_conn, request_conn)`` (in accordance with the
|
|
documentation) instead of one ``(request_conn)``.
