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 文件并生成正确的 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 代码中的注释表示它应该生成类似于以下内容的 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

为空。有谁知道如何确保这些字段设置正确？
