如何解决错误反向代理Nginx + Docker + Django项目后在此服务器上找不到请求的资源
当我尝试访问 localhost / auth / 时遇到问题，这可能是由于nginx配置所致，或者可能是其他问题。以下是我尝试向代理地址 localhost / auth /
提出请求后从nginx日志中获得的结果reverse-proxy | 0.0.0.0 - - [28/Aug/2020:08:21:47 +0000] "GET /api/ HTTP/1.1" 404 159 "-" "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML,like Gecko)
当我访问 http：// localhost / admin / 时，管理员登录页面将按预期显示，如下所示。同样在 http：// localhost / doc / ，redocs documentation页面也会呈现。

chatbot / urls.py
from django.conf.urls import url
from chatbot.views import ChatterBotApiView
urlpatterns = [
url(r'^chatbot/',ChatterBotApiView.as_view(),name='chatbot'),]
**当我访问localhost/api-auth时浏览器输出**
解决方法
rest_framework.urls没有索引视图：
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'),]
因此/auth/login应该可以工作。而且，它不会做您认为做的事。这提供了Django的标准登录和注销视图，并且不会通过REST进行身份验证。为此，请查看third party packages。
并查看Django Vue Auth Demo，以讨论使用分离的前端通过REST进行身份验证时的一些常见错误和陷阱。
