Python Zeep 错误 requests.exceptions.ConnectionError: HTTPSConnectionPool

分类：编程问答

如何解决Python Zeep 错误 requests.exceptions.ConnectionError: HTTPSConnectionPool

我正在尝试使用 zeep 向 SOAP Web 服务 (WSDL) 发出请求，但我不知道为什么会出现此错误。 Web 服务正在使用 SOAP UI 工作。我想我没有以正确的方式在 python 中传递参数，但是我在 Zeep 文档中研究这是正确的，我在 Ubuntu 20.04 和 Windows 10 中对其进行了测试，两者都出现了相同的错误。

使用 SOAP UI 请求：

    <soapenv:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:inf="http://infocomercial.cifin.asobancaria.com">
   <soapenv:Header/>
   <soapenv:Body>
      <inf:consultaXml soapenv:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">
     <in0 xsi:type="dto:ParametrosConsultaDTO" xmlns:dto="http://dto.infocomercial.cifin.asobancaria.com">
        <codigoInformacion xsi:type="soapenc:string" xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/">1401</codigoInformacion>
        <motivoConsulta xsi:type="soapenc:string" xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/">24</motivoConsulta>
        <numeroIdentificacion xsi:type="soapenc:string" xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/">80775779</numeroIdentificacion>
        <tipoIdentificacion xsi:type="soapenc:string" xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/">1</tipoIdentificacion>
     </in0>
      </inf:consultaXml>
   </soapenv:Body>
</soapenv:Envelope>

我的python代码：

import requests
from requests import Session
from requests.auth import HTTPBasicAuth  # or HTTPDigestAuth,or OAuth1,etc.
from zeep import Client
from zeep.transports import Transport
from zeep import xsd
from zeep.plugins import HistoryPlugin
from zeep.xsd import ComplexType
from lxml import etree

end_point= 'https://cifinpruebas.asobancaria.com/InformacionComercialWS/services/InformacionComercial?wsdl'
session = Session()
session.auth = HTTPBasicAuth("username","password")
session.cert='certificate.pem'
soap_client = Client(end_point,transport=Transport(session=session,timeout=60),service_name="InformacionComercialWSService",port_name="InformacionComercial")
parametros_consulta_dto = soap_client.get_type('ns0:ParametrosConsultaDTO')
parameters = parametros_consulta_dto(codigoInformacion="1401",motivoConsulta="24",numeroIdentificacion="80775779",tipoIdentificacion="1")
soap_client.service.consultaXml(parameters)

错误：

requests.exceptions.ConnectionError: HTTPSConnectionPool(host='ttuweb3.universo.corp',port=443): Max retries exceeded with url: /InformacionComercialWS/services/InformacionComercial (Caused by NewConnectionError('<urllib3.connection.HTTPSConnection object at 0x7f8e7d3d3af0>: Failed to establish a new connection: [Errno -2] Name or service not known'))

我已经花了几天时间寻找解决方案，但没有结果。谢谢。

编辑 1：SOAP UI 响应的图像

expected response

编辑 2：有关端点的 SOAP UI 信息的图像

endpoint information

另外，我按照本指南 reporting_bugs 测试了生成的 XML，并且我在 SOAP UI 中使用了它，它工作正常，我的参数没有问题，可能是在 SSL 身份验证中。

编辑 3：更改仅使用请求库的代码。 嗨，我决定仅使用请求库来测试soap 请求（也许zeep 可能会在身份验证中失败），但我确信这是来自网络服务提供商的服务器错误。

    import requests
from requests import Session
from requests.auth import HTTPBasicAuth

cert_file="path to cert"
key_file="path to key"

endpoint='https://cifinpruebas.asobancaria.com/InformacionComercialWS/services/InformacionComercial?wsdl'
session = Session()
session.auth = HTTPBasicAuth("user","password")

body = """<soapenv:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:inf="http://infocomercial.cifin.asobancaria.com">
<soapenv:Header/>
<soapenv:Body>
    <inf:consultaXml soapenv:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">
        <in0 xsi:type="dto:ParametrosConsultaDTO" xmlns:dto="http://dto.infocomercial.cifin.asobancaria.com">
            <codigoInformacion xsi:type="soapenc:string" xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/">1401</codigoInformacion>
            <motivoConsulta xsi:type="soapenc:string" xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/">24</motivoConsulta>
            <numeroIdentificacion xsi:type="soapenc:string" xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/">80775779</numeroIdentificacion>
            <tipoIdentificacion xsi:type="soapenc:string" xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/">1</tipoIdentificacion>
        </in0>
    </inf:consultaXml>
</soapenv:Body>
</soapenv:Envelope>"""

body = body.encode('utf-8')
session.headers = {"Content-Type": "text/xml; charset=utf-8"}
session.headers.update({"Content-Length": str(len(body))})
response = session.post(url=endpoint,data=body,cert=(cert_file,key_file))
print(response)

我使用的是 RSA PRIVATE KEY 和证书，但在响应中我收到以下错误：

    <Response [500]>
<?xml version="1.0" encoding="utf-8"?>
<soapenv:Envelope
    xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"
    xmlns:xsd="http://www.w3.org/2001/XMLSchema"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
    <soapenv:Body>  
        <soapenv:Fault>
            <faultcode
                xmlns:ns1="http://xml.apache.org/axis/">ns1:Client.NoSOAPAction
            </faultcode>   
            <faultstring>no SOAPAction header!</faultstring>  
            <detail>
                <ns2:hostname
                    xmlns:ns2="http://xml.apache.org/axis/">ttuweb3
                </ns2:hostname>  
            </detail>
        </soapenv:Fault>
    </soapenv:Body>
</soapenv:Envelope>

所以这是一个服务器错误，但我很困惑，因为我说请求正在使用 SOAP UI 工作。有什么解释吗？
