python - 如何使用 zeep 为签名添加时间戳？

Question

我正在尝试创建一个使用 WSDL 文件并生成适当的 SOAP 消息的客户端。这就是我创建客户端的方式:

client = Client(
        wsdl=wsdl
        ,transport = transport
        ,wsse = Signature('key.pem', 'cert.pem')
    )

zeep 代码中的注释说它应该生成类似于此的 XML:

  <soap:Header>
    <wsse:Security mustUnderstand="true">
      <wsu:Timestamp>
        <wsu:Created>2015-06-25T21:53:25.246276+00:00</wsu:Created>
        <wsu:Expires>2015-06-25T21:58:25.246276+00:00</wsu:Expires>
      </wsu:Timestamp>
    </wsse:Security>
  </soap:Header>

但是它没有添加 mustUnderstand 属性并且 TimeStamp 是空白的。有谁知道如何确保正确设置这些字段？
