python - 从 WSDL 在 python 中实现一个 SOAP 客户端

Question

我想在 python 中使用 SOAP Web 服务。但我没有为这项工作找到任何像样的 python 肥皂客户端库。像 Zeep 这样的库太基础了，不支持复杂的安全策略。

我在互联网上搜索了几天没有成功。我将非常感谢您的帮助。

在找不到好的 Python 客户端后，我决定实现自己的客户端，但是 Ws-* 协议太复杂了！（尤其是安全部分），有成千上万的规范页面！所以我输了（实际上问题不在于 WS-* 协议本身，是的，它很复杂，但是必须阅读其他相关规范，例如 XML Signature ，加密...）。

我知道如果我重新阅读规范，我最终将能够理解它并实现该库，但我没有时间了。

这是该服务的一些 WSDL：

            </wsp:All>
        </wsp:ExactlyOne>
    </wsp:Policy>
</wsdl:definitions>

有人可以简单地向我解释一下如何与这项服务交谈吗？

据我所知，有 5 个（或 4 个？！）策略都必须使用。我想我需要使用第<sp:EndorsingSupportingTokens>一个来获取令牌！然后在后续请求中使用该令牌。
