Python Spyne-为SOAP响应设置不同的mimetype

我已经让我的SpyneSOAP服务器运行，它工作得非常好，但我唯一的问题是我需要返回一个带有特定mimetype的响应

我返回的内容类型是

text/html; charset=utf-8

我需要回去

text/xml; charset=utf-8

我尝试以这种方式重写Soap11：

class CustomSoap11(Soap11):
    mime_type = 'text/xml; charset=utf-8'

但它不影响返回的内容类型

我也尝试过重写DjangoServer方法，但也不起作用

---

有什么建议吗？

我必须重写我的handle\u rpc函数来设置正确的头。默认情况下，HttpResponse返回它的默认值，因此我必须重写DjangoServer，并通过创建自定义django服务器和自定义SpyneView将其包含在SpyneView中
