Thanks. I had actually already found your page and you're right, it does seem to be the best resource out there. Since your email I've had a second look at it, as initially I wasn't sure how to use the example to return a web resource (handler with render_GET etc) in place of the file you returned. Turns out it wasn't actually too bad, and looks something like:<br>
<br>{code}<br><pre>from zope.interface import implements<br><br>from twisted.cred.portal import IRealm, Portal<br>from twisted.cred.checkers import FilePasswordDB<br>from twisted.web.static import File<br>from twisted.web.resource import IResource<br>
from twisted.web.guard import HTTPAuthSessionWrapper, DigestCredentialFactory<br><br>def secureServer():<br> class PublicHTMLRealm(object):<br> implements(IRealm)<br><br> def requestAvatar(self, avatarId, mind, *interfaces):<br>
if IResource in interfaces:<br> return (IResource, WebResource(), lambda: None)<br> raise NotImplementedError()<br><br> portal = Portal(PublicHTMLRealm(), [FilePasswordDB('httpd.password')])<br>
<br> credentialFactory = BasicCredentialFactory("MyRealm")<br> rsrc = HTTPAuthSessionWrapper(portal, [credentialFactory])<br><br> return rsrc<br><br>class WebResource(resource.Resource):<br> def __init__():<br>
....<br><br> def getChild(self, path, request):<br> if path == self.expected:<br> return ValidHandler()<br> else:<br> return InvalidUrlHandler()<br><br># Create server<br>my_server = secureServer(...)<br>
site = server.Site(my_server)<br></pre>{code}<br><br>This has worked great so far where ValidHandler contains a render_GET, but when calling a POST or PUT on handler that has render_POST or render_PUT using this technique returns a message which I think is Method Not Allowed (on the train right now, so don't have in front of me, sorry). Is there a better way to form the above to prevent this?<br>
<br>Thanks again<br>Brad<br><br><div class="gmail_quote">On 9 February 2010 10:02, <span dir="ltr"><<a href="mailto:exarkun@twistedmatrix.com">exarkun@twistedmatrix.com</a>></span> wrote:<br>...<br><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">
It's definitely true that there isn't a lot of documentation for Guard. I've written up something, though (which hopefully will soon be included in Twisted itself, to make it easier to find), which I think will get you up to speed on using Guard pretty quickly:<br>

<br>
The final example, which sets up an actual Twisted Web server protected by digest auth (basic is even easier), only takes 16 lines.<br>
<br>
If that's still not to your liking, then you can always fall back to the much more tedious, much less elegant, request.getUsername() and request.getPassword() approach. :) You'll have to rely on the API docs for that approach, though, as far as I know there are no prose-style introductions for it.<br>
