add header in request SOAP message in python

I try to add header when sending SOAP request in Python.

The header in SOAP is:

> <SOAP-ENV:Header> 
> <ns3:userCredentials
> xsi:type="https://4psa.com/HeaderData.xsd/2.0.0">
> <username>admin</username>  
> <password>welcome</password> 
> </ns3:userCredentials>
> </SOAP-ENV:Header>

I have used:

 from suds.client import Client
 from suds.xsd.doctor import ImportDoctor, Import
 wsdl = 'https://192.168.1.15//soap2/schema/2.5.0/Report/Report.wsdl'
 client = Client(wsdl)

and I don`t know how to add header to this code.

Please suggest how to add it.

And I tried:

> >>> from suds.client import Client
> >>> from suds.xsd.doctor import ImportDoctor, Import
> >>> imp = Import('http://schemas.xmlsoap.org/soap/encoding/')
> >>> url = 'https://192.168.1.15//soap2/schema/2.5.0/Report/Report.wsdl'
> >>> client = Client(url)
> >>> userid = 'admin'
> >>> passwd = '12345678@X'
> >>> client.set_options(soapheaders=(userid,passwd))
> >>> print client a get error when run:
> 
> >>> client.service.CallCosts(1) Traceback (most recent call last):

Please suggest if you know what is the problem here.

I did something like this

def client_with_token(token):
    header_ns = ('ns1', "http://4psa.com/HeaderData.xsd/3.5.0")
    access_token = Element('accessToken', ns=header_ns).setText(token)
    auth_header = Element('userCredentials', ns=header_ns)
    auth_header.append(access_token)
    client = Client(url)
    auth_header = get_auth_header()
    client.set_options(soapheaders=auth_header, *args, **kwargs)
    return client

The suds client has many that may be used to control the behavior of the library. Some are general options and others are transport options. Although, the options objects are exposed, the preferred and supported way to set/unset options is through:

• The Client constructor
• The Client.set_options()
• The Transport constructor(s).
