POST 500上的HTTP 500错误

Question

我按照这里的说明How can I login to django using tastypie创建一个UserResource，可以用来登录到我的django用户。

但是，我运行代码时遇到HTTP 500错误。我试图自己调试它，但无法弄清楚。我不知道如何解决500错误。任何想法，你可以表示赞赏。

谢谢！

我的代码如下：

#####api.py 
from registration.views import register 
from tastypie.resources import ModelResource 

from tastypie.constants import ALL 


from django.contrib.auth.models import User 
from django.contrib.auth import authenticate, login, logout 
from tastypie.http import HttpUnauthorized, HttpForbidden 
from django.conf.urls.defaults import url 
from tastypie.utils import trailing_slash 

class UserResource(ModelResource): 
    class Meta: 
     queryset = User.objects.all() 
     fields = ['first_name', 'last_name', 'email'] 
     allowed_methods = ['get', 'post'] 
     resource_name = 'user' 

    def prepend_urls(self): 
     return [ 
      url(r"^(?P<resource_name>%s)/login%s$" % 
       (self._meta.resource_name, trailing_slash()), 
       self.wrap_view('login'), name="api_login"), 
      url(r'^(?P<resource_name>%s)/logout%s$' % 
       (self._meta.resource_name, trailing_slash()), 
       self.wrap_view('logout'), name='api_logout'), 
     ] 

    def login(self, request, **kwargs): 
     self.method_check(request, allowed=['post']) 
     print "reached login auth" 
     data = self.deserialize(request, request.raw_post_data, format=request.META.get('CONTENT_TYPE', 'application/json')) 

     username = data.get('username', '') 
     password = data.get('password', '') 
     print "reached login auth" 
     user = authenticate(username=username, password=password) 
     if user: 
      if user.is_active: 
       login(request, user) 
       return self.create_response(request, { 
        'success': True 
       }) 
      else: 
       return self.create_response(request, { 
        'success': False, 
        'reason': 'disabled', 
        }, HttpForbidden) 
     else: 
      return self.create_response(request, { 
       'success': False, 
       'reason': 'incorrect', 
       }, HttpUnauthorized) 

    def logout(self, request, **kwargs): 
     self.method_check(request, allowed=['get']) 
     if request.user and request.user.is_authenticated(): 
      logout(request) 
      return self.create_response(request, { 'success': True }) 
     else: 
      return self.create_response(request, { 'success': False }, HttpUnauthorized) 

########test_login.py 
import requests

from urllib2 import urlopen

headers = {'Content-type': 'application/json', 'Accept': 'text/plain'} 
print json.dumps(data) 
r = requests.post(url, data=json.dumps(data), headers=headers) 
print r 

#####urls.py 
from userdetails.api import UserResource 
user_resource = UserResource() 
urlpatterns = patterns('', 
    ...... 
    (r'^api/', include(user_resource.urls)), 
    )

当使用print语句可以提高IOErrors通过WSGI部署。尝试将它们注释掉或重定向输出。

In Django, how do I allow print statements to work with Apache WSGI?

附加一个斜线在你的主机上的日志

url = 'http://127.0.0.1:8000/api/user/login/'
