[docs] @cherrypy.expose def index(self): # Ask for the user's name. return ''' <form action="greetUser" method="GET"> What is your name? <input type="text" name="name" /> <input type="submit" /> </form>'''
[docs] @cherrypy.expose def greetUser(self, name=None): # CherryPy passes all GET and POST variables as method parameters. # It doesn't make a difference where the variables come from, how # large their contents are, and so on. # # You can define default parameter values as usual. In this # example, the "name" parameter defaults to None so we can check # if a name was actually specified. if name: # Greet the user! return "Hey %s, what's up?" % name else: if name is None: # No name was specified return 'Please enter your name <a href="./">here</a>.' else: return 'No, really, enter your name <a href="./">here</a>.'
