我一直在尝试将djangorestframework simplejwt添加到我的Web应用程序中，每当我使用路由器添加视图时(请参阅下面代码中的2个注释路由器(，我都会收到一个错误(请参阅回溯(。
当按照文档中的说明在urlpatterns变量下添加url时，它不会出现任何错误。我想知道为什么router.register(..)不起作用，为了良好的秩序(和我的OCD(，是否可以将其从urlpatters变量中移到路由器。
from django.urls import path, include
from rest_framework import routers
from . import views
from django.conf.urls import url
from django.contrib import admin
from rest_framework_simplejwt.views import (
TokenObtainPairView,
TokenRefreshView,
)
app_name = 'myapi'
router = routers.DefaultRouter()
router.register(r'posts', views.PostViewSet)
router.register(r'user', views.UserViewSet)
router.register(r'likes', views.LikesViewSet)
# router.register(r'token',TokenObtainPairView.as_view())
# router.register(r'token/refresh',jwt_views.TokenRefreshView.as_view())
urlpatterns = [
path('', include(router.urls)),
path('api-auth/', include('rest_framework.urls', namespace='rest_framework')),
path('token/', TokenObtainPairView.as_view(), name='token_obtain_pair'),
path('token/refresh/', TokenRefreshView.as_view(), name='token_refresh'),
]

路由器使用ViewSets，而不使用API视图，因此无法在该级别添加它们。
在Django领域，每个url都映射到一个视图函数，Router的工作是通过将GET路由到list()函数等，将ViewSet转换为Django的path知道如何处理的函数列表。因此router.urls是Djangopath实例的列表。
如果你真的喜欢混淆别人，你甚至可以手动操作！
snippet_list = SnippetViewSet.as_view({
'get': 'list',
'post': 'create'
})
path('snippets/', snippet_list, name='snippet-list'),
您现在添加它们的方式是正确的。as_view是一个DRF函数，它将APIView或相关类转换为视图函数，供django的path使用。
我有一个route()助手，你可能会觉得有帮助。它统一了视图、".urls"、视图集的路由，并取代了path()。我发现这是我多年来最大的挫折之一。
urlpatterns = [
route('students/', 'student.urls'),
route('users/', UserViewSet, name='user'),
route('register/', RegisterView, name='register'),
