如何使用 Python zeep 库与 SOAP Webservice 建立连接？

如何解决如何使用 Python zeep 库与 SOAP Webservice 建立连接？

首先，这是我第一次使用 SOAP Webservice，所以我试图了解如何解释它。我所做的第一步是读取 wsdl 文件，为此我需要插入网络服务提供商提供的用户名和密码。网络服务如下所示：

    <?xml version="1.0" encoding="UTF-8"?>

     </binding>

     <service name="InformacionComercialWSService">

      <port name="InformacionComercial" binding="intf:InformacionComercialSoapBinding">

           <wsdlsoap:address location="https://ttuweb3.universo.corp/InformacionComercialWS/services/InformacionComercial"/>

      </port>

     </service>

</definitions>

我可以根据这个文件解释以下内容：

  • 服务名称：InformacionComercialWSService
  • 端口名称：InformacionComercial
  • 可能的操作：consultaXml、consultaPlano 和 cambioPassword

所以，根据webservice的开发环境，我需要将这个信息作为参数传递： 'codigoInformacion':"1401",'motivoConsulta':"24",'numeroIdentificacion':"80775779",'tipoIdentificacion':"1"

以下是有效的 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>

另外我需要插入公司的认证以确认请求的足迹。为此，我决定实施 Python 开发，因为这是我的主要语言。我找到了一个名为 Zeep 的库，它允许将其用作肥皂客户端。 webservice文档说认证应该是Http Basic，这是我拥有的唯一信息。

所以我安装要求如下：

python = "^3.8"
zeep = "^4.0.0"

之后，我需要研究信息以使用Zeep进行编码，结果是这样的：

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

session = Session()
session.cert = "XXXXXX/certificate.pem"
session.auth = HTTPBasicAuth("XXXXXX","XXXX")

end_point= 'https://cifinpruebas.asobancaria.com/InformacionComercialWS/services/InformacionComercial?wsdl'
soap_client = Client(end_point,transport=Transport(session=session),service_name="InformacionComercialWSService",port_name="InformacionComercial")

print("conexión establecida en :" + end_point)

request_data = {
    'codigoInformacion':"1401",'tipoIdentificacion':"1"
    }

print(soap_client.service.consultaXml(**request_data))

我可以解决过程中的很多困难，但是我一直在以下错误中花费了很多时间，我不明白如何解决它，并且webservice公司不支持编码，因为他们只有信息在 Java 和 .Net 中。错误是：

    Traceback (most recent call last):

    print(soap_client.service.consultaXml(**request_data))

    raise TypeError(
TypeError: ComplexType() got an unexpected keyword argument 'codigoInformacion'. Signature: `in0: {http://dto.infocomercial.cifin.asobancaria.com}ParametrosConsultaDTO`

我认为，我没有以正确的方式传递参数，但我不太了解 WSDL 文件，我正在尝试更改以下请求：

print(soap_client.service.consultaXml(**{'ParametrosConsultaDTO':request_data}))

但错误是一样的...

    Traceback (most recent call last):
  File "prueba_wsdl.py",in <module>
    print(soap_client.service.consultaXml(**{'ParametrosConsultaDTO':request_data}))
  File "/home/steven/.cache/pypoetry/virtualenvs/soap-conexion-hvcf0k35-py3.8/lib/python3.8/site-packages/zeep/proxy.py",in _process_signature
    raise TypeError(
TypeError: ComplexType() got an unexpected keyword argument 'ParametrosConsultaDTO'. Signature: `in0: {http://dto.infocomercial.cifin.asobancaria.com}ParametrosConsultaDTO`

按照此代码 https://stackoverflow.com/a/50093489/2607773 我可以收集：

{'InformacionComercialWSService': {'InformacionComercial': {'operations': {'cambioPassword': {'input': {'in0': {'optional': False,'type': {'_value_1': {'optional': False,'type': 'String(value)'}}}}},'consultaPlano': {'input': {'in0': {'optional': False,'type': {'codigoInformacion': {'optional': False,'type': 'String(value)'}}},'motivoConsulta': {'optional': False,'numeroIdentificacion': {'optional': False,'tipoIdentificacion': {'optional': False,'type': 'String(value)'}}}}}}},'consultaXml': {'input': {'in0': {'optional': False,'type': 'String(value)'}}}}}}}}}}}

所以我将 request_data 更改为：

request_data = {
        
            'in0': {
            
                'codigoInformacion': {
                
                
                    '_value_1': {
                    'optional': False,'type': "1401"
                    }
                
                },'motivoConsulta': {
                
                
                    '_value_1': {
                    'optional': False,'type': "24"
                    }
                
                },'numeroIdentificacion': {
                
                
                    '_value_1': {
                    'optional': False,'type': "80775779"
                    }
                
                },'tipoIdentificacion': {
                
                
                    '_value_1': {
                    'optional': False,'type': "1"
                    }
                
                }
            
            } 
}

但我收到另一个错误：

    Traceback (most recent call last):
  File "prueba_wsdl.py",line 79,in serialize
    self.body.render(body,body_value)
  File "/home/steven/.cache/pypoetry/virtualenvs/soap-conexion-hvcf0k35-py3.8/lib/python3.8/site-packages/zeep/xsd/elements/element.py",line 232,in render
    self._render_value_item(parent,value,render_path)
  File "/home/steven/.cache/pypoetry/virtualenvs/soap-conexion-hvcf0k35-py3.8/lib/python3.8/site-packages/zeep/xsd/elements/element.py",line 256,in _render_value_item
    return self.type.render(node,None,render_path)
  File "/home/steven/.cache/pypoetry/virtualenvs/soap-conexion-hvcf0k35-py3.8/lib/python3.8/site-packages/zeep/xsd/types/complex.py",line 295,in render
    element.render(node,element_value,child_path)
  File "/home/steven/.cache/pypoetry/virtualenvs/soap-conexion-hvcf0k35-py3.8/lib/python3.8/site-packages/zeep/xsd/elements/indicators.py",line 251,in render
    element.render(parent,child_path)
  File "/home/steven/.cache/pypoetry/virtualenvs/soap-conexion-hvcf0k35-py3.8/lib/python3.8/site-packages/zeep/xsd/elements/element.py",line 293,in render
    element.type.render(node,child_path)

  File "/home/steven/.cache/pypoetry/virtualenvs/soap-conexion-hvcf0k35-py3.8/lib/python3.8/site-packages/zeep/xsd/types/builtins.py",line 27,in _wrapper
    raise ValueError(
ValueError: The String type doesn't accept collections as value

我所做的另一件事是使用 Factory 对象，如 factory object zeep 中的文档所述：

factory = soap_client.type_factory('ns0')
request = factory.ParametrosConsultaDTO(codigoInformacion="1401",motivoConsulta="24",numeroIdentificacion="80775779",tipoIdentificacion="1")

print(request)
try:
    print(soap_client.service.consultaXml(request))
except requests.exceptions.ConnectionError as e:
    response = "Without response"
    print(response)

但它显示另一个错误：

urllib3.exceptions.NewConnectionError: <urllib3.connection.HTTPSConnection object at 0x7fb685c865b0>: Failed to establish a new connection: [Errno -2] Name or service not known

我确认 .pem 证书仍然可用并且它适用于 SOAP UI。

如果有人可以帮助我，我很感激，也许我快要解决了。
