Python WSDL客户端的身份验证问题

Question

我一直在尝试连接到wsdl，在我弄清楚之前无法继续。在

from suds.client import Client

client = Client('<https_wsdl_url>')

print(client)

kwargs = {'username': '<username>', 'password': '<password>', 'type': '',}
response = client.service.Login(**kwargs)

print(response)

打印客户端表明可以使用以下方法调用该方法：

^{pr2}$

我收到一个错误的身份验证错误，即使身份验证在soapUI中有效。stacktrace是：

No handlers could be found for logger "suds.client"
Traceback (most recent call last):
