LinkedHashMap中的entrySet（）是否也保证订单？(Does entrySet() in a LinkedHashMap also guarantee order?)

 那么，最后，我继承了REST Framework TokenAuthentication，并在urls文件中指向它 
 
url(r'^api-token-auth/', back_views.TokenAuthenticationView.as_view()),
 
 并且视图处理请求并手动调用update_last_login，如下所示： 
 
from django.contrib.auth.models import update_last_login

class TokenAuthenticationView(ObtainAuthToken):
    """Implementation of ObtainAuthToken with last_login update"""

    def post(self, request):
        result = super(TokenAuthenticationView, self).post(request)
        try:
            request_user, data = requests.get_parameters(request)
            user = requests.get_user_by_username(data['username'])
            update_last_login(None, user)            
        except Exception as exc:
            return None
        return result

Well, at the end I inherited from the REST Framework TokenAuthentication, pointing to it in the urls file
 
url(r'^api-token-auth/', back_views.TokenAuthenticationView.as_view()),
 
and the View handles the request and manually calls the update_last_login like this:
 
from django.contrib.auth.models import update_last_login

class TokenAuthenticationView(ObtainAuthToken):
    """Implementation of ObtainAuthToken with last_login update"""

    def post(self, request):
        result = super(TokenAuthenticationView, self).post(request)
        try:
            request_user, data = requests.get_parameters(request)
            user = requests.get_user_by_username(data['username'])
            update_last_login(None, user)            
        except Exception as exc:
            return None
        return result
