我对 Python 作为 PHP 背景的新手感到很困惑。

我试图了解如何从这个Python 路由库调用在路由中设置的控制器。

例如，我有这样设置的路线，

# Setup a mapper
from routes import Mapper
map = Mapper()
map.connect("add user", "/user", controller = "addUser", action = "add",
  conditions=dict(method=["GET"]))
map.connect("post user", "/user", controller = "postUser", action = "post", 
  conditions=dict(method=["POST"]))
map.connect("update user", "/user/{id}", controller = "updateUser", action = "update", 
  conditions=dict(method=["GET"]))
map.connect("put user", "/user/{id}", controller = "putUser", action = "put", 
  conditions=dict(method=["PUT"]))
map.connect("delete user", "/user/{id}", controller = "deleteUser", action = "delete", 
  conditions=dict(method=["DELETE"]))
map.connect("home", "/", controller = "main", action = "index", conditions=dict(method=["GET"]))

# This is our application object. It could have any name,
# except when using mod_wsgi where it must be "application"
def application(environ, start_response):

   # Get the request path info.
   uri = environ.get('PATH_INFO', '')
   path_info = uri if uri else '/'

   # Get the HTTP request method: PUT, GET, DELETE, POST.
   request_method = environ.get('REQUEST_METHOD', '')
   map.environ = {'REQUEST_METHOD': request_method}

   # Match a URL, returns a dict or None if no match
   mapped = map.match(path_info)

   # Everything done, return the response:
   if mapped['action'] == 'index' :
      response_body = index(environ, start_response, mapped)
   elif mapped['action'] == 'add':
      response_body = addUser(environ, start_response, mapped)
   elif mapped['action'] == 'put':
      response_body = putUser(environ, start_response, mapped)
   elif mapped['action'] == 'delete':
      response_body = deleteUser(environ, start_response, mapped)
   else:
      response_body =  "Not found."

   status = '200 OK'

   response_headers = [('Content-Type', 'text/html'),
               ('Content-Length', str(len(response_body)))]
   start_response(status, response_headers)

   return [response_body]

如您所见，在路由中设置的控制器根本没有使用。当匹配时，我在 if-else 条件下调用单个函数。这是乏味和蹩脚的...

这不是我在 PHP 中的做法（我猜你可能也不会在 Python 中这样做）。因为我希望路由会在请求匹配时直接调用控制器 -没有任何进一步的 if-else 条件。

知道如何在没有controller = "addUser"下面的情况下调用addUser函数吗？

elif mapped['action'] == 'add':
   response_body = addUser(environ, start_response, mapped)

它似乎以这种方式工作，

# Setup a mapper
from routes import Mapper

def main():

   return 'Hello World!'

def addUser():

   return 'Add User'

def deleteUser():

   return 'Delete User'

# This is our application object. It could have any name,
# except when using mod_wsgi where it must be "application"
def application(environ, start_response):

   # Get the request path info.
   uri = environ.get('PATH_INFO', '')
   path_info = uri if uri else '/'

   # Get the HTTP request method: PUT, GET, DELETE, POST.
   request_method = environ.get('REQUEST_METHOD', '')
   map.environ = {'REQUEST_METHOD': request_method}

   # Match a URL, returns a dict or None if no match
   mapped = map.match(path_info)

   # Everything done, return the response:
   response_body =  mapped['controller'].encode('utf-8')

   status = '200 OK'

   response_headers = [('Content-Type', 'text/html'),
               ('Content-Length', str(len(response_body)))]
   start_response(status, response_headers)

   return [response_body]

main = main()
addUser = addUser()
deleteUser = deleteUser()

map = Mapper()
map.resource("user", "users")
map.connect("add user", "/user", controller = addUser, action = "add",
   conditions=dict(method = ["GET"]))
map.connect("delete user", "/user/{id}", controller = deleteUser, action = "delete",
   conditions=dict(method = ["DELETE"]))
map.connect("home", "/", controller = main, action = "index",
   conditions=dict(method = ["GET"]))
