我在用Python发送SOAP请求的时候，想要添加一个头部信息。

SOAP中的头部信息是：

> <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>

我使用了：

 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)

但是我不知道怎么把头部信息加到这段代码里。

请告诉我怎么添加。

我还尝试过：

> >>> 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):

如果你知道这里有什么问题，请告诉我。

suds客户端有很多选项可以用来控制这个库的行为。有些是通用选项，有些是传输选项。虽然这些选项对象是可以使用的，但推荐和支持的设置或取消选项的方式是通过以下几种方法：

客户端构造函数

Client.set_options() 方法

传输构造函数。

soapheaders – 用于提供soap头信息。

我做了类似这样的事情

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
