Django 请求 CAC（通用访问卡）

Question

我目前正在 Apache v2.4.5.2 服务器上运行我的 Django 应用程序。当用户点击初始页面（即 www.djangoApp.com）时，系统会提示他们插入 CAC 和 PIN。完成后，PIN 输入弹出窗口将消失，用户将被引导至登录页面。我遇到的问题是弄清楚如何根据从外部源 (GCDS) 收到的 HTTP 响应来识别用户。在服务器日志中，我可以看到请求信息，但我不确定如何在 Django 视图中查看该请求。我尝试注释掉所有中间件，以便请求能够通过，但这不起作用。 Apache 是否会阻止某些 HTTP 请求？我需要在某个地方允许外部请求吗？我收到的唯一请求是：

我尝试构建自己的中间件，注释掉所有中间件......我被困住了。如何查看包含 CAC 信息的 GCDS 请求？ Apache 是否会阻止某些 HTTP 请求？我需要在某个地方允许外部请求吗？

这是来自views.py的登陆页面：

def landing(request):
    test = request.META
    print(test)
    dodNum = "101010101"
    people = Person.objects.all()
    for person in people:
        if dodNum in person.authentication_name:
       
            return render(request, 'webdart/landing.html', {'person': person})
            break
    return render(request, 'webdart/accountRequest.html')

同样，当我打印“test”变量时，我看到的只是对登陆页面/accountRequest页面的请求。请求中没有身份验证信息

Answer 1

该问题与 Apache 端的命名标头有关。 Django 会删除所有以下划线（“_”）命名的标头。但是，如果您使用破折号（“-”），django 将接受标头并将破折号转换为下划线。

我们在 httpd-ssl.conf 文件中将其更改

RequestHeader set REMOTE_USER "%{SSL_CLIENT_S_DN_CN}s"

为：

RequestHeader set REMOTE-USER "%{SSL_CLIENT_S_DN_CN}s"

现在在我们的views.py中，我们可以调用request.META并获取所有身份验证信息。即使使用中间件，请求也会处理所有数据。
