General variable tips that also apply to servlets are in section 13.1.
To look up a CGI GET or POST parameter (with POST overriding):
$request.field('myField')
self.request().field('myField')
$request
(aka self.request() will be None rather than a Webware
WebKit.Request object. If you plan to read a lot of CGI parameters,
you may want to put the .fields method into a local variable for
convenience:
#set $fields = $request.fields $fields.myField
$request
forms are useful only for occasions where you just need one or two simple
request items that going to Python for would be overkill.
To get a cookie or session parameter, subsitute ``cookie'' or ``session'' for ``field'' above. To get a dictionary of all CGI parameters, substitute ``fields'' (ditto for ``cookies''). To verify a field exists, substitute ``hasField'' (ditto for ``hasCookie'').
Other useful request goodies:
## Defined in WebKit.Request
$request.field('myField', 'default value')
$request.time ## Time this request began in Unix ticks.
$request.timeStamp ## Time in human-readable format ('asctime' format).
## Defined in WebKit.HTTPRequest
$request.hasField.myField ## Is a CGI parameter defined?
$request.fields ## Dictionary of all CGI parameters.
$request.cookie.myCookie ## A cookie parameter (also .hasCookie, .cookies).
$request.value.myValue ## A field or cookie variable (field overrides)
## (also .hasValue).
$request.session.mySessionVar # A session variable.
$request.extraURLPath ## URL path components to right of servlet, if any.
$request.serverDictionary ## Dict of environmental vars from web server.
$request.remoteUser ## Authenticated username. HTTPRequest.py source
## suggests this is broken and always returns None.
$request.remoteAddress ## User's IP address (string).
$request.remoteName ## User's domain name, or IP address if none.
$request.urlPath ## URI of this servlet.
$request.urlPathDir ## URI of the directory containing this servlet.
$request.serverSidePath ## Absolute path of this servlet on local filesystem.
$request.serverURL ## URL of this servlet, without "http://" prefix,
## extra path info or query string.
$request.serverURLDir ## URL of this servlet's directory, without "http://".
$log("message") ## Put a message in the Webware server log. (If you
## define your own 'log' variable, it will override
## this; use $self.log("message") in that case.
