这是django1.11版本的写法，最近我换成了django2.2，发现用法不一样。

总体上变化不大，变成了
URLPattern, URLResolver
url = pre_url + item.pattern.regex.pattern # /^rbac/^user/edit/(?P<pk>\d_+)/$
recursion_urls(namespace, pre_url + item.pattern.regex.pattern, item.url_patterns, url_ordered_dict)
recursion_urls(None, '/', urlpatterns, url_ordered_dict) # 递归的去获取所有的路由。根目录没有namespace，根路由用/
