Spyne和Django-丝绸的请求后错误

Question

我已经在Django中使用spyne作为SOAP服务器。我安装了django-丝绸来监控请求。对于GET请求，它可以正常工作，但是当我使用POST时，我会得到下面的错误和超时。如果我把django-丝绸移走，它就可以用了。斯宾的django.py of spyne在有个问题

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

错误是以下

Traceback (most recent call last):
  File "/home/test/django/django-apps/venv-test/lib/python2.7/site-packages/django/core/handlers/exception.py", line 41, in inner
    response = get_response(request)

StopIteration

有什么想法吗？

Probaby丝绸正在使用返回值中的生成器，这不会给客户机留下任何数据。

我在文档中简要地提到了这一点：types.html#arrays

..。返回值可以是生成器，除非将数据返回给客户端，否则不能使用。这对诸如自定义记录器是有用的，因为他们不应该尝试记录返回值(因为这意味着要消耗生成器)。

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