Answer 1

不幸的是，get_or_create()无法按照您展示的方式运行，也就是说，它不会跨越关系。您必须有现有用户才能创建令牌：

>>> user = User.objects.get(username='username') # Or create one
>>> Token.objects.get_or_create(user=user)

Answer 2

请参阅https://github.com/tomchristie/django-rest-framework/blob/master/rest_framework/authtoken/models.py#L21了解Token型号代码。

您必须传递User个对象，而不仅仅是用户名/密码的组合。

首先创建用户myuser，然后执行Token.objects.get_or_create(myuser)。
