客戶端代碼：

# 需要安裝zeep
from requests import Session
from zeep import Client
from zeep.transports import Transport

# 這裏省略了一段代碼

session = Session()  # 這裏是因爲url是https，不然不需要transport
session.verify = False
transport = Transport(session=session)
url = 'http://www.example.com/api?wsdl'
url = 'http://127.0.0.1:8000?wsdl'
client = Client(url, transport=transport)
result = client.service.car_condition_price('zhangsan', 1, 2, '1,45,56')
print(result)

訪問wsdl文檔如下：

遠程服務調用失敗，注意到location爲127.0.0.1。

故添加如下代碼設置location地址：

wsgi_application.doc.wsdl11.build_interface_document("https://www.example.com/api")

 wsdl頁面變爲設置的域名：

遠程服務調用可以正常使用。
