在 POST 后重定向并传递数据时重定向 URL 的持久性

Question

成功提交表单后，我重定向到 "success" 页面，该页面显示 'thank you' 消息以及有关提交的一些信息。为此，我将 POST 数据放入会话中，重定向到适当的 URL，然后使用会话数据呈现模板。

但是，这意味着如果有人手动导航到 'success' URL，他们将看到来自上一个表单提交的 "success" 消息。我该如何防止呢？表单在 /register/ 处处理。成功的提交将重定向到 /register/success。我希望在浏览器中实际键入 /register/success/ 的人（没有提交表单）看到错误页面或其他内容。如何处理？

urls.py

url(r'^register/$', views.register, name='register'),
url(r'^register/success/$', views.registration_success, name='registration_success'),

views.py

def register(request):
    if request.method == 'POST':
        if the_form.is_valid():
            my_id = the_form.cleaned_data['myid']
            email_addr = the_form.cleanedJ_data['emailaddr']
            request.session['registration'] = {'my_id': my_id, 'email_addr': email_addr }

            return HttpResponseRedirect(reverse('polls:registration_success'))


def registration_success(request):
    template = loader.get_template('polls/submitted.html')
    context = RequestContext(request, request.session.get('registration'))
    return HttpResponse(template.render(context))

你可以使用Django session来实现that.Here是用你的代码的例子

def register(request):
    if request.method == 'POST':
        if the_form.is_valid():
            my_id = the_form.cleaned_data['myid']
            email_addr = the_form.cleanedJ_data['emailaddr']
            request.session['registration'] = {'my_id': my_id, 'email_addr': email_addr }
            request.session['form-submitted'] = True
            return HttpResponseRedirect(reverse('polls:registration_success'))


def registration_success(request):
    if not request.session.get('form-submitted', False):
        # handle the case where there is no form submitted
        return HttpResponseRedirect(reverse('polls:register'))
    template = loader.get_template('polls/submitted.html')
    context = RequestContext(request, request.session.get('registration'))
    return HttpResponse(template.render(context))
