Spyne和Django-silk的請求后錯誤

Question

我已經將spyne-RPC用作Django中的SOAP服務器。 我已經安裝了django-silk來監視請求。 對於我的GET請求，它工作正常，但是當我使用POST時，出現以下錯誤和超時。 如果我刪除django-silk，就可以了。 spyne的django.py處存在問題

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

錯誤如下

Traceback (most recent call last):

StopIteration

有任何想法嗎？

概率django-silk正在使用返回值中的生成器，該返回值不會為客戶端留下任何數據。

我在文檔中簡要提到了這一點： http : //spyne.io/docs/2.10/manual/03_types.html#arrays

...返回值可能是生成器，除非將數據返回給客戶端，否則不能使用返回值。 這對於例如自定義記錄器很方便，因為它們不應嘗試記錄返回值（因為這將消耗生成器）。

如果您可以自己消耗生成器並將其替換為具有相同數據的列表或元組，則可以正常工作。
