Question

我正在尝试通过Zeep进行SOAP调用。 WSDL不包含标头定义，但是SOAP服务器需要以下标头：

<soapenv:Header>
  <ns2:UsernameToken xmlns:ns2="http://siebel.com/webservices">ORNODINTFC_WW@ORACLE.COM</ns2:UsernameToken>
</soapenv:Header>

这是我按照zeep文档进行操作的方式：

header = xsd.Element(
     '{http://siebel.com/webservices}UsernameToken',
      xsd.AnySimpleType()    
)

header_val = header('ORNODINTFC_WW@ORACLE.COM')

client.create_message(client.service, 'process', _soapheaders=[header_val],payload=msg, Mode='ODRFCQUERY', UserName='ORNODINTFC_WW@ORACLE.COM', Password='0r10nTkn')

但是，对于create_message我遇到以下错误

Traceback (most recent call last):
  File "<pyshell#119>", line 1, in <module>
    xml_msg = client.create_message(client.service, 'process', _soapheaders=[header_val],payload=msg, Mode='ODRFCQUERY', UserName='ORNODINTFC_WW@ORACLE.COM', Password='0r10nTkn')

header = self._serialize_header(headers_value, nsmap)

raise ValueError("Invalid value given to _soapheaders")
ValueError: Invalid value given to _soapheaders

请提出解决方法

Zeep ValueError：赋予_soapheaders的值无效
