python - int() 参数必须是字符串或数字，而不是 'SimpleLazyObject'

Question

我正在通过 Aliexpress API 开发网络应用程序。

但是我遇到了一些问题，比如我的标题。

我的观点如下:

def getToken(request):
appKey = 'test12345'
appSecret ='test3456'
redirectUrl = 'http://127.0.0.1:8000/'
#post to submit the request
postdata=urllib.urlencode({
    'grant_type':'authorization_code',
    'need_refresh_token':True,
    'client_id':appKey,
    'client_secret':appSecret,
    'redirect_uri':redirectUrl,
    'code':request.GET['code'],
    })
req = urllib2.Request(
    url = 'https://gw.api.alibaba.com/openapi/http/1/system.oauth2/getToken/%s' % appKey ,
    data = postdata)
#get access_token
value = eval(urllib2.urlopen(req).read())

#Checking the shop
check = aliexpressToken.objects.filter(user=request.user, aliid=value['aliId'])
if check:
    return HttpResponseRedirect("/shop/")
else:        
    result = aliexpressToken(user=request.user, aliid=value['aliId'], resource_owner=value['resource_owner'], refresh_token=value['refresh_token'], access_token=value['access_token'],shop_name='Aliexpress Trade')
    result.save()
    #get the id of shop which just is added.
    shop =  aliexpressToken.objects.get(aliid=value['aliId'], user=request.user.id).id
    return HttpResponseRedirect("/shop/%s/edit" % shop)

模型:

class aliexpressToken(models.Model):
    """docstring for aliexpressToken"""
    user = models.ForeignKey(User)
    aliid = models.CharField(max_length=30)
    resource_owner = models.CharField(max_length=30)
    refresh_token = models.CharField(max_length=50)
    access_token = models.CharField(max_length=50)
    shop_name = models.CharField(max_length=50)
    shop_color = models.CharField(max_length=30)
    shop_image = models.CharField(max_length=30)
    create_time = models.DateTimeField(auto_now_add=True)

当我尝试测试从 Aliexpress 获取访问权限时，它会提醒我 int() 参数必须是字符串或数字，而不是 'SimpleLazyObject' 。我能做些什么。非常感谢像这样的错误回溯，它为我提供了更多信息。但我无法分析发生了什么。
