[Twisted-web] twisted.web.wsgi usage example

[Waldemar Osuch]

Hi,
I'm trying to come up with an example on how to use the spanking new
twisted.web.wsgi
module.  Here it is.  Any comments?

from twisted.internet import reactor
from twisted.application import service, internet
from twisted.web import server, static, wsgi
from twisted.python import threadpool


def wsgi_app(environ, start_response):
    status = '200 OK'
    response_headers = [('Content-type', 'text/plain')]
    start_response(status, response_headers)
    return ['Hello from twisted.web.wsgi']


class WSGIService(service.Service):
    def __init__(self, minPoolSize=5, maxPoolSize=20):
        self.pool = threadpool.ThreadPool(minPoolSize, maxPoolSize)

    def startService(self):
        self.pool.start()
        service.Service.startService(self)

    def stopService(self):
        self.pool.stop()
        service.Service.stopService(self)


application = service.Application('wsgi')

root = static.File("www/documents")
site = server.Site(root)
internet.TCPServer(8080, site).setServiceParent(application)

serv = WSGIService()
root.putChild('wsgi', wsgi.WSGIResource(reactor, serv.pool, wsgi_app))
serv.setServiceParent(application)
