Api 请求 WSDL Python答案

【问题描述】：

我正在尝试通过 Python 中的 wsdl-soap 建立 api 连接。

这是我使用的代码。

import zeep
wsdl = 'http://dev.gittigidiyor.com:8080/listingapi/ws/CategoryService?wsdl'
client = zeep.Client(wsdl=wsdl)


send_data=[{

'cat:getCategories' :[

{
'startOffSet' : 0,
'rowCount' : 4,
'withSpecs':'true',
'withDeepest':'true',
'withCatalog':'true',
'lang':'tr'
}
     ] } ]


print(client.service.getCategories(send_data))

官方documentation建议：

WSDL 地址： http://dev.gittigidiyor.com:8080/listingapi/ws/CategoryService?wsdl

服务方法签名： CategoryServiceResponse getCategories(int startOffSet, int rowCount, boolean withSpecs, boolean withDeepest, boolean withCatalog, String lang)

请求示例

<cat:getCategories>
   <startOffSet>0</startOffSet>
   <rowCount>4</rowCount>
   <withSpecs>true</withSpecs>
   <withDeepest>true</withDeepest>
   <withCatalog>true</withCatalog>
   <lang>tr</lang>
</cat:getCategories>

但是我无法从源中获取任何数据。我收到如下错误：

    print(client.service.getCategories(send_data))

任何帮助（新库建议、代码更正等）都将得到应用。

提前致谢！

【解决方案1】：

我终于解决了我自己的问题。我错过的是它需要一个身份验证层。

这里是那些可能需要解决类似问题的人的代码。

from requests import Session
from requests.auth import HTTPBasicAuth 
from zeep import Client
from zeep.transports import Transport

session = Session()
session.auth = HTTPBasicAuth('user_name', 'password')

client = Client('wsdl_url',
    transport=Transport(session=session))


print(client.service.service_name(parameter1,parameter2,parameter3..))

这是我使用的source..
