===============================
Example -- Serving Static Files
===============================
Helpfully you can also return a :api:`twisted.web.resource.IResource <t.w.resource.IResource>` such as :api:`twisted.web.static.File <t.w.static.File>`.
If ``branch=True`` is passed to ``route`` the returned ``IResource`` will also be allowed to handle all children path segments.
So ``http://localhost:8080/static/img.gif`` should return an image and ``http://localhost:8080/static/`` should return a directory listing.
.. code-block:: python
from twisted.web.static import File
from klein import run, route
@route('/static/', branch=True)
def static(request):
return File("./static")
@route('/')
def home(request):
return '<img src="/static/img.gif">'
run("localhost", 8080)
In production environments, you might want to disable directory listings so
that you do not accidentally expose more information than you intend. To
disable directory listings, override the ``directoryListing`` method for the
:api:`twisted.web.static.File <t.w.static.File>` class.
.. code-block:: python
from twisted.web.static import File
from klein import run, route
from werkzeug.exceptions import NotFound
@route('/static/', branch=True)
def static(request):
return FileNoDir("./static")
@route('/')
def home(request):
return '<img src="/static/img.gif">'
class FileNoDir(File):
def directoryListing(self):
raise NotFound()
run("localhost", 8080)
