在工作中，我必须访问/使用Channel Advisor API 来源：
我正在尝试执行一个简单的OrderService
from suds.client import Client
wsdl_url = 'https://api.channeladvisor.com/ChannelAdvisorAPI/v6/OrderService.asmx?WSDL'
service_url = 'https://api.channeladvisor.com/ChannelAdvisorAPI/v6/OrderService.asmx'
headers = {'Content-Type': 'text/xml; charset=utf-8'}
client = Client(wsdl_url, location = service_url, headers=headers)
这是错误：
Traceback (most recent call last):
