如何使用zeep发送xml请求？

问题描述

我正在努力了解如何使用python请求数据。我使用zeep在代码中实现了wsdl文件。我认为问题是正文请求，即xml格式。欢迎任何帮助！

from requests import Session
from zeep import Client,Settings
from zeep.transports import Transport

session = Session()
session.verify = ('my_pem_file.pem')
transport = Transport(session=session)
settings = Settings(strict=False,xml_huge_tree=True)
client = Client("my_wdsl_file.xml",transport=transport,settings=settings)


anfrage = '''<item>
               <NAME>VAR_NAME_1</NAME>
               <VALUE>/SIE/PD_VASHU004</VALUE>
            </item>'''

print(client.service.RRW3_GET_QUERY_VIEW_DATA("/SIE/PD_PFI21","",anfrage,"EPIQ_FINANCIALS"))

如果运行终端命令python -wzeep "my_wsdl_file.xml，则会得到以下方法定义：

ns0:RRW3_GET_QUERY_VIEW_DATA(I_INFOPROVIDER: ns0:char30,I_QUERY: ns0:char30,I_T_PARAMETER: ns0:RRXW3TQUERY,I_VIEW_ID: ns0:char30)

因此，我放置了char30提供程序，即空的char30查询，但我不知道如何转换xml正文请求以及特定格式是什么。

如果我像这样运行代码段，则会得到以下异常树。

TypeError: string indices must be integers

解决方法

您是否可以共享运行python -mzeep的其余输出？ ns0:RRXW3TQUERY类型的定义是什么？
