当我将设置中的

Debug=True

更改为

Debug=False

时，我已经在Google compute engine上部署了带有python 3.6项目的Django 1.10。它会在我的一个post请求上抛出服务器错误（500）。甚至其他post请求（如注册）也可以正常工作。当我停止gunicorn进程并再次运行它时，这篇文章会运行几个小时，然后再次抛出服务器错误（500）

在计算引擎上使用Django 1.10.5和Python3.6时，如何解决这个问题？请帮帮我！提前谢谢

正如上面评论中的讨论，您可以将异常处理放在代码中，并将

logger

放在代码中。例如：

import logging


class TagView(LoginRequiredMixin, generic.CreateView):
    form_class = forms.TagForm

    def post(self, request, *args, **kwargs):
        try:
            post_data = request.POST.copy()
            post_data.update({'user': request.user.pk})
            form = forms.TagForm(post_data)
            if form.is_valid():
                tag = form.save(commit=False)
                tag.user = request.user
                tag.email = request.user.email
                tag.save()
            else:
                return HttpResponse(form.errors, status=400)

            return HttpResponseRedirect(reverse_lazy('users:dashboard'))

        except Exception as exp:
          logging.error(exp)  # For python 3
          return HttpResponse(exp, status=400)

并使用日志监控工具查看错误日志，如本文所述：

有关异常处理的详细信息：

***根据回答中评论中的讨论，问题在于

允许的\u主机

。设置

ALLOWED_HOSTS=['*']

或在允许的主机中设置服务器的IP解决了此问题。

尝试进行异常处理并添加适当的记录器以查明确切的错误。否则，很难说它为什么会出错。嗨，@ruddra！你是说，我需要把异常处理放在我的视图中吗？是的。然后放一个记录器来存储异常我怎么做？请我是django的新手。我已经在下面给出了答案，因为我不能将所有内容都放在注释部分@AbdulRehmanTry，在本地运行此代码时使用DEBUG=FALSE，如果代码在本地运行时没有错误，那么就将其放在google云存储上。我已经在计算引擎实例中直接克隆了我的代码！在这种情况下，请尝试使用DEBUG=FALSE运行，检查是否有任何错误。您的域是否设置在

允许的主机中

？但也可以使用

DEBUG=TRUE

运行数小时，然后开始失败。
