Question

我已经在Django中将spyne-RPC用作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。

的spyne的django.py出现问题

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

以下是错误

Traceback (most recent call last):

StopIteration

有什么想法吗？

Probaby django-silk在返回值中消耗了生成器，而返回值没有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，除非被使用，否则不得使用将数据返回给客户端。这对于例如习俗记录器，因为他们不应该尝试记录返回值（因为将意味着消耗发电机）。

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。
