tornado自定义实现django include方法

tornado自定义实现django  include方法

• 自定义URLmethod模块

•  1 from Custom.errors import *
   2 
   3 
   4 def include(base_url, expand_url):
   5     # base_url必须是字符串类型
   6     if not isinstance(base_url, str):
   7         raise TypeError("base_url must be String type, but {} is not".format(str(base_url)))
   8 
   9     # 必须在拓展的urls里面有一个urlpatterns的对象,如果没有就会引发AttributeError
  10     getattr(expand_url, ‘urlpatterns‘)
  11 
  12     if not isinstance(expand_url.urlpatterns, (list, tuple)):
  13         raise UrlError(
  14             "expand_url.urlpatterns must be a list or tuple, but {} is not".format(str(expand_url.urlpatterns)))
  15 
  16     urlpatterns = expand_url.urlpatterns
  17 
  18  
  19     new_urlpatterns = []
  20 
  21     for url in urlpatterns:
  22 
  23         items = []
  24         new_base_url = base_url + url[0]  # 将原始的url和拓展的url拼接
  25         items.append(new_base_url)
  26         items.append(url[1])
  27         new_urlpatterns.append(tuple(items))
  28 
  29     return new_urlpatterns
  30 
  31 
  32 def extend(*args):
  33     # 将所有的include元素拓展成新的列表
  34     urlpatterns = []
  35     for urlpattern in args:
  36         if isinstance(urlpatterns, list):
  37             urlpatterns.extend(urlpattern)
  38         else:
  39             raise UrlError
  40     return urlpatterns

   

• 自定方法的使用

•  1 from tornado.web import Application
   2 from tornado.ioloop import IOLoop
   3 from tornado.httpserver import HTTPServer
   4 from tornado.options import options, define
   5 from Custom.URL_method import include, extend
   6 from Robot import urls
   7 
   8 
   9 define(‘port‘, default=80, type=int)
  10 
  11 settings = {
  12     ‘template_path‘: ‘templates‘,
  13     ‘static_path‘: ‘static‘,
  14     ‘debug‘: True
  15 }
  16 
  17 
  18 urlpatterns = extend(
  19     include("", urls),
  20     include(r‘/qrcode‘, urls),
  21 )
  22 
  23 
  24 
  25 
  26 
  27 
  28 app = Application(handlers=urlpatterns, **settings)
  29 
  30 if __name__ == ‘__main__‘:
  31     options.parse_command_line()
  32     http = HTTPServer(app)
  33     http.listen(options.port)
  34     IOLoop.current().start()

   

• 自定义url模块

• 1 from . import views
  2 
  3 
  4 urlpatterns = [
  5     (r‘/index‘,  views.IndexHandler),
  6     (r‘/test‘,  views.TestHandler)
  7 ]

• views模块

•  1 from tornado.web import RequestHandler
   2 
   3 
   4 
   5 class IndexHandler(RequestHandler):
   6     def get(self):
   7         self.write("hello")
   8 
   9 
  10 class TestHandler(RequestHandler):
  11     def get(self):
  12         self.write("test page")
