参考官方安装指南Yii advanced template installation提到：
It uses asset-packagist for managing bower and npm package dependencies through Composer. Also you can use asset-plugin, as in earlier versions, but it works slowly.

Composer + Bower + NPM = friends forever!
This repository allows installation of Bower and NPM packages as native Composer packages.
NO plugins and NO Node.js are required.
At the moment we’ve added most popular Bower and NPM packages 4000+ each.
In case Composer fails to install some asset package, use the search line at the top of the page to check specific package health.
For NPM scoped packages use scope--package instead of @scope/package, e.g. npm-asset/pusher--chatkit.
Got tired of fxp/composer-asset-plugin.
Got tired of fxp/composer-asset-plugin.
It’s a good project with nice idea and good implementation. But it has some issues: it slows down composer update a lot and requires global installation, so affects all projects. Also there are Travis and Scrutinizer integration special problems, that are a bit annoying.
修改settings.py增加rest_framework.authtoken
INSTALLED_APPS = (
'rest_framework',
'rest_framework.authtoken',
'myapp',
)
增加权限验证
REST_FRAMEWORK = {
'DEFAULT_PERMISSION_CLASSES': (
'rest_framework.permissions.IsAdminUser',
),
'DEFAULT_AUTHENTICATION_CLASSES': (
'rest_framework.authentication.SessionAuthentication',
'rest_framework.authentication.TokenAuthentication',
)
}
升级表可以看到增加了authtoken_token表
python manage.py migrate
编辑urls.py
from rest_framework.authtoken import views
urlpatterns = [
path('admin/', admin.site.urls),
url(r'^', include(router.urls)),
url(r'^api-auth/', include('rest_framework.urls', namespace='rest_framework')),
url(r'^api-token-auth/', views.obtain_auth_token),
]
