Tutorial - The default method
|
|
|
|
Request handler objects can implement a method called "default" that
|
|
is called when no other suitable method/object could be found.
|
|
Essentially, if CherryPy2 can't find a matching request handler object
|
|
for the given request URI, it will use the default method of the object
|
|
located deepest on the URI path.
|
|
|
|
Using this mechanism you can easily simulate virtual URI structures
|
|
by parsing the extra URI string, which you can access through
|
|
cherrypy.request.virtualPath.
|
|
|
|
The application in this tutorial simulates an URI structure looking
|
|
like /users/<username>. Since the <username> bit will not be found (as
|
|
there are no matching methods), it is handled by the default method.
