Spyne和Django-silk的请求后错误

Question

我已经将spyne-RPC用作Django中的SOAP服务器。 我已经安装了django-silk来监视请求。 对于我的GET请求，它工作正常，但是当我使用POST时，出现以下错误和超时。 如果我删除django-silk，就可以了。 spyne的django.py处存在问题

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？

概率django-silk正在使用返回值中的生成器，该返回值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

...返回值可能是生成器，除非将数据返回给客户端，否则不能使用返回值。 这对于例如自定义记录器很方便，因为它们不应尝试记录返回值（因为这将消耗生成器）。

如果您可以自己消耗生成器并将其替换为具有相同数据的列表或元组，则可以正常工作。
