Does anyone have a simple example of processing either a post or put on
the server side using web2? I've had no problem serving up web pages
from a variety of sources (files, database backends). The changes
needed to support data back fro the user -- undoubtedly a set of
deferred methods in the right place -- escape me. Thanks.
For POST, you could use resource.PostableResource, which will take
care of parsing your run-of-the-mill form posting. Just subclass
resource.PostableResource, and implement the "render" method.
For PUT, and also for cases where your are POSTING non-form data,
e.g., an XML payload, you need to subclass resource.Resource,
implement the desired method (http_POST, http_PUT), and then hook
the request.stream up to a processing chain.
Example:
from twisted.web2 import resource, stream
class Foo(resource.Resource):
_allowedMethods = ('POST', 'PUT')
def _finished(self, result, request):
# return some http.Response
def _failed(self, reason, request):
# return some http.Response
def http_POST(self, request):
def handleData(data):
# process each chunk of data as it arrives
# readStream will keep calling handleData until the
# entire stream has been read.
d = stream.readStream(request.stream, handleData)
# these callbacks/errbacks will be called when readStream
# has finished reading the stream.
d.addCallbacks(
self._finished,
self._failed,
callbackArgs=(request,),
errbackArgs=(request,)
)
# Catch any errors that occur in self._finished.
d.addErrback(self._failed, request)
return d
def http_PUT(self, request):
# Just handle things the same way POST does
return self.http_POST(request)
Hope this helps,
