从文章中和 RDS 项目中得到灵感：DjangoRestFramework 也是有自己的登录页面的
-
DjangoRestFramework 的登录页
urls.pyfrom rest_framework import routers from rest_framework.authtoken import views as drf_auth_views urlpatterns = [ ......... # 学习 restframework 的 login 和 TokenAuthentication # https://blog.csdn.net/qq_39980136/article/details/89503850 url(r'^drf/', include('rest_framework.urls')), ----- DRF 的登录 url 和 视图函数 url(r'^drf_token/', drf_auth_views.obtain_auth_token), ----- DRF 居然给提供了这么现成的接口 url(r'^auth/', include('django.contrib.auth.urls')), ]
D:\xxx\venv\Lib\site-packages\rest_framework\urls.py
from django.conf.urls import url
from django.contrib.auth import views
app_name = 'rest_framework'
urlpatterns = [
url(r'^login/$', views.LoginView.as_view(template_name='rest_framework/login.html'), name='login'),
url(r'^logout/$', views.LogoutView.as_view(), name='logout'),
]
发现了上图就是 D:\xxx\venv\Lib\site-packages\rest_framework\templates\rest_framework\login.html
- Django 原生的登录页, ‘registration/login.html’ Django 框架中并没有该文件只是文件名字固定了，需要开发者提供内容
仔细分析上面的代码 D:\xxx\venv\Lib\site-packages\rest_framework\urls.py 可以看到其使用的就是 Django 原生的 LoginView
