我正在使用 pyadomd 连接到 azure 分析服务并尝试刷新数据模型。连接成功，但出现以下错误“命名空间 http://schemas.microsoft.com/analysisservices/2003/engine) 无法出现在 Envelope/Body/Execute/Command 下”。我假设我错误地执行了 XMLA 命令？可能是我构造 XMLA 命令的方式吗？我认为 xmlns 命名空间可能已被弃用或不再可用？非常感谢任何帮助，因为没有太多关于此的文档。在运行脚本之前，我使用 azure-cli 包运行 az login，以便可以在本地进行身份验证。我正在使用 python 3.8

全力输出

第一个链接包含有关使用的命名空间的信息，第二个链接包含可用命名空间的列表。
我尝试过的事情
使用替代命名空间，例如 http://schemas.microsoft.com/analysisservices/2022/engine/922/922 http://schemas.microsoft.com/analysisservices/2019/engine http://schemas.microsoft.com/analysisservices/2012/engine
得到同样的错误，所以假设它不是命名空间。
尝试使用肥皂信封格式，但也不起作用
refresh_command = f"""

问题似乎出在 XMLA 命令的结构上，该命令的格式不适合 Azure Analysis Services。您应该为 Azure Analysis Services 使用正确的 XMLA 结构，包括适当的 SOAP 信封和命名空间。
试一试：
