Detailed Explanation of url Mapping of python Script Framework webpy

Directory instance problem

URL exact match (specific url)

/index

URL Fuzzy Matching (You have no idea what follows index, it will not return parameters at all)

/index/\d

URL with group matching (there is mainly a '()', which is mainly used to return parameters, and 1 in the class you are dealing with must have a parameter accepted)

/baidu/(.*)

Instances

import web
urls=('/index','AbsoluteUrl',
    '/index/\d','AmbiguousUrl',
    '/index/(.*)','GroupUrl')
# Specific url Handling class 
class AbsoluteUrl:
    def GET(self):
        web.header('Content-type','text/html;charset=utf-8')
        return u'URL Exact match '
# Fuzzy url Handling class 
class AmbiguousUrl:
    def GET(self):
        web.header('Content-type','text/html;charset=utf-8')
        return u'URL Fuzzy matching '
# Grouped url Handling class 
class GroupUrl:
    def GET(self,name):  # If you have a band match here, 1 Be sure to add parameters , Used to receive the parameters you return 
        web.header('Content-type','text/html;charset=utf-8')
        return u'URL Band group matching --'+name
app=web.application(urls,globals())
if __name__ == '__main__':
    app.run()

Problem

1. Why urls can't use dict is it related to its principle
2. What else does globals () do
3. Why is http://0.0. 0.0: 8080/? Why do we have to use localhost: 8080 when we run? What are the benefits of this design?
