~~~~~~~~~~~~~~~~
|
|
|
|
There are many ways to serve a WSGI application. While you're developing
|
|
it you usually don't want a full blown webserver like Apache but a simple
|
|
standalone one. From Python 2.5 onwards there is the `wsgiref`_ server in
|
|
the standard library. If you're using older versions of Python you can
|
|
download the package from the cheeseshop.
|
|
|
|
However there are some caveats. Sourcecode won't reload itself when
|
|
changed and each time you kill the server using ``^C`` you get an
|
|
`KeyboardInterrupt` error. While the latter is easy to solve the first
|
|
one can be a pain in the ass in some situations.
|
|
|
|
The easiest way is creating a small ``start-myproject.py`` that runs the
|
|
application::
|
|
|
|
#!/usr/bin/env python
|
|
# -*- coding: utf-8 -*-
|
|
from myproject import make_app
|
|
from werkzeug.serving import run_simple
|
|
|
|
app = make_app(...)
|
|
run_simple('localhost', 8080, app, use_reloader=True)
|
|
|
|
You can also pass it a `extra_files` keyword argument with a list of
|
|
additional files (like configuration files) you want to observe.
|
|
|
|
For bigger applications you should consider using `werkzeug.script`
|
|
instead of a simple start file.

support for SSL was added.

Added support for automatically loading a SSL context from certificate

|

Added command-line interface.
|

Improved the reloader and added support for changing the backend

through the `reloader_type` parameter. See :ref:`reloader`
|
|
for more information.
|
|
|
|
:param hostname: The host for the application. eg: ``'localhost'``
|
|
:param port: The port for the server. eg: ``8080``
|
|
:param application: the WSGI application to execute
|
|
:param use_reloader: should the server automatically restart the python
|
|
process if modules were changed?
|
|
:param use_debugger: should the werkzeug debugging system be used?
|
|
:param use_evalex: should the exception evaluation feature be enabled?
|
|
:param extra_files: a list of files the reloader should watch
|
|
additionally to the modules. For example configuration
|
|
files.
|
|
:param reloader_interval: the interval for the reloader in seconds.
|
|
:param reloader_type: the type of reloader to use. The default is
|
|
auto detection. Valid values are ``'stat'`` and
|
|
``'watchdog'``. See :ref:`reloader` for more
|
|
information.
|
|
:param threaded: should the process handle each request in a separate
|
|
thread?
|
|
:param processes: if greater than 1 then handle each request in a new process
|
|
up to this maximum number of concurrent processes.
|
|
:param request_handler: optional parameter that can be used to replace
|
|
the default one. You can use this to replace it
|
|
with a different
|
|
:class:`~BaseHTTPServer.BaseHTTPRequestHandler`
|
|
subclass.
|
|
:param static_files: a dict of paths for static files. This works exactly
|
|
like :class:`SharedDataMiddleware`, it's actually
|
|
just wrapping the application in that middleware before
|
|
serving.
|
|
:param passthrough_errors: set this to `True` to disable the error catching.
|
|
This means that the server will die on errors but
|
|
it can be useful to hook debuggers in (pdb etc.)
|
|
:param ssl_context: an SSL context for the connection. Either an
|
|
:class:`ssl.SSLContext`, a tuple in the form
|
|
``(cert_file, pkey_file)``, the string ``'adhoc'`` if
|
|
the server should automatically create one, or ``None``
|
|
to disable SSL (which is the default).
