python - AppEngine confusion - CGI, WSGI-compliant? -

i'm confused.

if appengine supposed allow running of wsgi-employing apps ..

# somewhere in webapp.requesthandler env = dict(os.environ.items()) key, value in env.items(): self.response.out.write(key+': '+value+'<br/>') req_uri = wsgiref.util.request_uri(env)

.. why env not contain variables pep 333 lists must-be-present -- causing wsgiref.util.request_uri() raise keyerror?

i'm writing libraries need work either appengine or typical apache + modwsgi setup. thought plenty write wsgi compliant app, seems appengine .. not?

the environ must contain wsgi specific keys environ passed wsgi application callable. pep-333 not require value os.environ. cgi applications find many of keys in os.environ, because gateway server has provided them, , cgi wsgi gateway interface (say, wsgiref.handlers.cgihandler,) need add together wsgi specific keys before calling wsgi application.

to clear, when pep-333 mentions environ, does not mean os.environ.

edit: google.appengine.ext.webapp.request apparently inherits webob.request. thus, webapp handler can access wsgi environ so.

class mainpage(webapp.requesthandler): def get(self): dosomethingwith(self.request.environ)

python google-app-engine wsgi wsgiref
