如何设置DRF可浏览API根视图并显示所有API的URL？

在Django REST Framework中，我们可以通过使用DRF的Browsable API来更方便地浏览API根目录以及API endpoints，下面给出实现方法：

1. 在settings.py中添加以下内容以启用Browsable API支持：

INSTALLED_APPS = [
    'rest_framework',
    'rest_framework.authtoken',
    'rest_framework_docs',
    'rest_framework_swagger',
    'rest_framework_api_key',
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'users',
]

REST_FRAMEWORK = {
    'DEFAULT_SCHEMA_CLASS': 'rest_framework.schemas.coreapi.AutoSchema',
    'DEFAULT_RENDERER_CLASSES': (
        'rest_framework.renderers.CoreJSONRenderer',
        'rest_framework.renderers.BrowsableAPIRenderer',
    ),
    'DEFAULT_AUTHENTICATION_CLASSES': (
        'rest_framework.authentication.TokenAuthentication',
        'rest_framework.authentication.SessionAuthentication',
        'rest_framework_api_key.authentication.CachedAPIKeyAuthentication',
    ),
    'DEFAULT_PERMISSION_CLASSES': (
        'rest_framework.permissions.IsAuthenticated',
    ),
}

SWAGGER_SETTINGS = {
    'USE_SESSION_AUTH': False,
    'SECURITY_DEFINITIONS': {
        'api_key': {
            'type': 'apiKey',
            'name': 'Authorization',
            'in': 'header',
        }
    }
}

2. 创建一个urls.py文件，定义好所有的API endpoint，并将它们包含在Django的urlpatterns中。再将所有的API urls加入到DRF的router中。

from django.contrib import admin
from django.urls import include, path
from drf_yasg.views import get_schema_view
from drf_yasg import openapi
from rest_framework import permissions

schema_view = get_schema_view(
    openapi.Info(
        title="API Title",
        default_version='v1',
    ),
    public=True,
    permission_classes=(permissions.AllowAny,),
)

urlpatterns = [
    path('admin/', admin.site.urls),
    path('api/v1/', include('app1.urls')),
    path('api/v1/', include('app2.urls')),
    # 添加此行，用于访问 DRF API 路由
    path('', include('rest_framework.urls', namespace='rest_framework'))
]

# router 注册 API 路由（自动路由）
from rest_framework import routers
router = routers.SimpleRouter()

router.register(r'users', UserViewSet, basename='user')
router.register(r'rooms', RoomViewSet)
router.register(r'bookings', BookingViewSet)

urlpatterns =
