2. HTTP Authentication

3. Session
http://twistedmatrix.com/documents/current/web/howto/web-in-60/session-basics.html

from twisted.web.resource import Resource

class ShowSession(Resource):
    def render_GET(self, request):
        return 'Your session id is: ' + request.getSession().uid

class ExpireSession(Resource):
    def render_GET(self, request):
        request.getSession().expire()
        return 'Your session has been expired.'

resource = ShowSession()
resource.putChild("expire", ExpireSession())

Start the Service
> twistd -n web --path . --logfile ./RestAPI.access.log

Visit the page to get the session info
http://localhost:8080/RestAPI.rpy

Visit the expire the session
http://localhost:8080/RestAPI.rpy/expire

Store Object in the Session

4. Restful
> git clone https://github.com/iancmcc/txrestapi.git

> python setup.py install

This may works in project sillycat-prest

One Main File RestAPI.py to handle all the traffic
from twisted.web.resource import Resource
from twisted.web.server import Site
from twisted.internet import reactor

from BookAPI import BookResource

bookResource = BookResource()

rootResource = Resource()
rootResource.putChild("book", bookResource)

site = Site(rootResource, timeout=None)
reactor.listenTCP(8888,site)
reactor.run()

One Module Class BookAPI to handle the traffic in that module
from txrestapi.methods import GET, POST, PUT, ALL, DELETE
from txrestapi.resource import APIResource

class BookResource(APIResource):
    @GET('^/book/(?P<id>[^/]+)')
    def getBook(self, request, id):
        return 'Pick up one book with id %s' % id

    @GET('^/book')
    def books(self,request):
        return "books"

    @PUT('^/book/(?P<id>[^/]+)')
    def updateBook(self,request):
        return "Update book with id %s" % id

    @POST('^/book/(?P<id>[^/]+)')
    def saveBook(self, request, id):
        return "Save book with id %s" % id

    @DELETE('^/book/(?P<id>[^/]+)')
    def deleteBook(self,request,id):
        return "Delete book with id %s" % id

    @ALL('^/')
    def default_view(self, request):
        return "I fail to match other URLs."

The visits on the URL will work
http://localhost:8888/book/19343
