django：通过HttpResponseRedirect传递已发布的文件

提问于

我想通过HttpResponseRedirect将request.FILES从post表单传递给另一个表单，我尝试使用会话变量，但我无法通过它们传递文件 . 可能吗 ？如果没有：我怎么能这样做？

我想传递XML文件的原因是因为我需要在我使用HttpResponseRedirect重定向到的下一个视图中显示文件的已处理数据 . 这是一个片段：

# View that handles post data
dev my_view(request):
    if request.method == "POST":
        form = myForm(request.POST, request.FILES)
        my_file = request.FILES['xml']
        if form.is_valid():
            # Magic for passing files to the next view
            # I tried with session variables, but I couldn't pass
            # the file, as it couldn't be serialized.
            return HttpResponseRedirect(reverse('form2'))

dev my_view2(request):
    pass
    # Here I'd receive the data from the previous form
    # and handle it according to my needs.

提前致谢 .

    您无法将发布的文件保留在HTTP重定向上 - 这就是HTTP的工作方式 .

    如果重定向不是绝对必要的，您可以直接从第一个调用第二个视图函数：

    # View that handles post data
dev my_view(request):
    if request.method == "POST":
        form = myForm(request.POST, request.FILES)
        my_file = request.FILES['xml']
        if form.is_valid():
            # Magic for passing files to the next view
            # I tried with session variables, but I couldn't pass
            # the file, as it couldn't be serialized.
            return my_view2(request)   # <<<<<<< directly call the second view

dev my_view2(request):
    pass
    # Here I'd receive the data from the previous form
    # and handle it according to my needs.
