如何使用 SOAPpy 调用 IBM IMM 方法

Question

我正在尝试使用 SOAPpy 调用 IBM IMM（集成管理模块）的各种 SOAP 方法。不幸的是，我对 SOAP 相当陌生，根本无法弄清楚。

我没有任何类型的 WSDL，所以我不得不求助于观察我的浏览器在发出各种请求时会做什么。

进行的实际调用如下所示：

POST /wsman HTTP/1.1
Host: 192.168.0.166

Referer: http://192.168.0.166/

  </SOAP-ENV:Body>
</SOAP-ENV:Envelope>

和响应：

</s:Envelope>

我正在尝试使用 SOAPpy 正确生成此请求，但我根本没有到达任何地方，我不知道该怎么做或更改才能发出此请求。这是我到目前为止尝试过的：

>>> sess = imm.ImmWeb()
Session ID: 8b3af28d-a746-4fc5-af02-b4560f85cac1
>>> server = SOAPpy.SOAPProxy('http://imm/wsman',namespace='http://www.ibm.com/iBMC/sp/Tasks')
>>> server.transport.cookies['session_id'] = '3f19329f-468b-4c86-b6e7-2197b1ed62aa'
>>> server.invoke('http://www.ibm.com/iBMC/sp/Tasks/GetKVMStatus', {})

最好

使用远程服务器上的 WSDL 文件来指定方法（函数）及其相应的参数和数据类型。

此外，您将有机会确切地知道要建立的 SOAP 连接的命名空间、编码和格式。

尝试使用：

SERVER=SOAPpy.WSDL.Proxy('http://remote.server.url/service.wsdl')

直接使用 SOAPpy.Proxy 将使得有必要将正确的参数添加到您正在与之通信的服务器中。
