I offer the following implementations of keys() and items() for Z Publisher Request objects:

def keys(self): keys = {} for key in self.environ.keys(): if isCGI_NAME(key) or key[:5] == 'HTTP_': keys[key] = 1 keys.update(self.other) lasturl = "" for n in "0123456789": key = "URL%s"%n try: if lasturl != self[key]: keys[key] = 1 lasturl = self[key] else: break except KeyError: pass for n in "0123456789": key = "BASE%s"%n try: if lasturl != self[key]: keys[key] = 1 lasturl = self[key] else: break except KeyError: pass return keys.keys()

def items(self): result = [] for k in self.keys(): result.append((k, self[k])) return result

They probably aren't useful in general settings, but are useful for people like myself who aren't familiar with what's in a Request and want to explore a bit.

I don't want to add this, because I don't want to maintain it. If I have a choice between maintaining the above function (which is incorrect, BTW) and maintaining documentation, I'd rather maintain documentation. But if alot of people would consider the above method useful, I'll reluctantly add (a corrected version of) it.

Also, when using this, I discovered what may be a bug. It's at least a feature. I am using ZopeHTTPServer. When I examine the REQUEST argument of a URL, among other things I find

PATH_INFO: '/check_request' PATH_TRANSLATED: '/home/dolphin/skip/src/Zope-1.9.0b3-src/check_request' SCRIPT_NAME: '/' URL: 'http://127.0.0.2:8043/check_request'

I suppose in a Z Publisher context the distinction between elements of PATH_INFO and elements of SCRIPT_NAME is fuzzy, but it seems somehow more intuitive to me that I should see

PATH_INFO: '' PATH_TRANSLATED: '/home/dolphin/skip/src/Zope-1.9.0b3-src' SCRIPT_NAME: '/check_request' URL: 'http://127.0.0.2:8043/check_request'

instead. In a CGI context you always have a non-empty SCRIPT_NAME. You might or might not have a non-empty PATH_INFO. Given that SCRIPT_NAME and PATH_INFO are holdovers from CGI, I think it makes sense to pile everything into SCRIPT_NAME and leave PATH_INFO empty.

The script name is the URL up to the name of the application. PATH_INFO is the part of the URL after the application name and is used to march into the application. With ZopeHTTPServer, the web server *is* the application, so SCRIPT_NAME must be ''. Jim -- Jim Fulton mailto:jim@digicool.com Technical Director (540) 371-6909 Python Powered!
