First, here's a sample test program:

MyWebServer instance
self.send_response(200)
self.send_header('Content-type', 'text/html')
self.end_headers()
self.wfile.write("thanks for trying, but I'd like to get at
self.foo and self.bar")
return
class MyWebServer(object):
def __init__(self):
self.foo = "foo" # these are what I want to access from inside
do_GET
self.bar = "bar"
self.httpd = HTTPServer(('127.0.0.1', 8000), MyRequestHandler)
sa = self.httpd.socket.getsockname()
print "Serving HTTP on", sa[0], "port", sa[1], "..."
def runIt(self):
self.httpd.serve_forever()
server = MyWebServer()
server.runIt()

I want to access the foo and bar variables from do_GET, but I can't
figure out how. I suppose this is something to do with new-style vs.
old-style classes, but I lost for a solution.
It'd have been good to tell us that this was on Python 2.7
Is MyWebServer class intended to have exactly one instance? If so, you
could save the instance as a class attribute, and trivially access it
from outside the class.
If it might have more than one instance, then we'd need to know more
about the class BaseHTTPServer.HTTPServer, From a quick glance at the
docs, it looks like you get an attribute called server. So inside the
do_GET() method, you should be able to access self.server.foo and
self.server.bar
See http://docs.python.org/2/library/basehttpserver.html
That doesn't work. Maybe you mean something that I'm missing?
