反向代理Nginx+Docker+Django项目后，在此服务器上找不到请求的资源

问题描述 投票：0回答：2

当我尝试访问 localhost/auth/ 时遇到问题，这可能是由于 nginx 配置或可能是另一个其他问题。以下是我尝试向代理地址 localhost/auth/

发出请求后从 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呈现，如下所示。另外，在 http://localhost/doc/ redocs 文档 页面也会呈现。

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'),
]

所以 

/auth/login
应该有效。而且，它不会做你想象的那样。这提供了 Django 的标准登录和注销视图，并且不通过 REST 进行身份验证。请查看第三方软件包。 并查看 Django Vue Auth Demo，讨论使用分离前端通过 REST 进行身份验证时的一些常见错误和陷阱。

我也有类似的问题。原因是 Settings.py 中的 Debug = False 并且安装是全新的生产环境。 我的解决方案是设置 Debug = True 直到定义视图之后。

https://stackoverflow.com/questions/14951468/who-generates-the-default-page-of-django-welcome-page#:~:text=如果%20your%20urls.py%20是%20page %20you're%20seeing.&text=%20default%20landing%20page%20that,html%22.

如果你的 urls.py 为空（如不包含任何匹配 url 的模式）并且 Django 处于调试模式（设置中的 DEBUG = True），那么 Django 会触发你所看到的页面。第一次运行 django Web 应用程序时看到的默认登录页面是“default_urlconf.html”。
