Django：/panel/home/login/'HTTP_REFERER'处出现KeyError

Question

我在从 django 获取 HTTP_REFERER 地址时遇到问题。 我想在两个单独的登录页面中使用用户身份验证系统，为此，我在其中一个登录页面中设置，如果将人员重定向到此登录页面的 URL 包含“业务”一词，则将用户重定向到业务登录页面。 感谢您的帮助

我写了这段代码：

if 'business' in request.META['HTTP_REFERER']:
return redirect('panel_business:login_business')

这是我的错误：

KeyError at /panel/home/login/  'HTTP_REFERER'

Django 错误完整跟踪：

好的，我找到了一个简单的方法:)

@login_required(login_url='your login url')
def your_page(request):
    # something ...
