我已经在 Django 中使用 spyne-RPC 作为 SOAP 服务器。我已经安装了 django-silk 来监控请求。对于我的 GET 请求，它可以正常工作，但是当我使用 POST 时，我得到下面的错误和超时。如果我删除 django-silk 它可以正常工作。spyne 的 django.py 有一个问题

response = WsgiApplication.__call__(self, environ, start_response)

错误如下

Traceback (most recent call last):

    response = get_response(request)

StopIteration

有任何想法吗？

Probaby django-silk 在返回值中使用生成器，这不会为客户端留下任何数据。

我在文档中简要提到了这一点：http: //spyne.io/docs/2.10/manual/03_types.html#arrays

...返回值可以是生成器，除非将数据返回给客户端，否则不得使用。这对于例如自定义记录器来说很方便，因为它们不应该尝试记录返回值（因为这意味着消耗生成器）。

如果您可以以某种方式自己使用生成器并将其替换为具有相同数据的列表或元组，则它可以工作。
