Django

Question

我有一个登录页面 A，我在其中获取 User/Pwd 信息和 post 到另一个第 3 方网站，并获得 JSON 格式的 sessionid 变量。当我 redirect/render 摄取页面 B 时，我需要这个 sessionid 变量在 displayed/available 那里。

这是我试过的方法，但我似乎无法让它工作。有人可以帮忙吗？

<h2>Session Id {{ request.session.get('sessionid') }}</h2>

Answer 1

您可以将此值保存到 Django 的 session。在第一个视图中：

sessionid=response.json()['icSessionId']
request.session['sessionid'] = sessionid

在第二个视图中：

class IngestionView(TemplateView):
    template_name = 'registration/ingestion.html'


    def post(self, request):
        form1 = IngestionForm(request.POST)
        sessionid=request.session['sessionid']
        args1 = {"form": form1, 'sessionid': sessionid}
        return render(request, self.template_name, args1)
