xsi:type 属性未解析为类型定义

Question

你们知道如何修复它吗？我尝试将 type_name 作为 Lead 传递，但它也不起作用。

xmlns：soap11env =“http://schemas.xmlsoap.org/soap/envelope/”>soap11env：Bodysoap11env：Faultsoap11env：Client.SchemaValidationError：1：0：错误：SCHEMASV：SCHEMAV_CVC_ELT_4_2： 元素“{http://soap.sforce.com/2005/09/outbound}sObject”，属性 '{http://www.w3.org/2001/XMLSchema-instance}type'：QName 值 xsi:type 的“{urn:sobject.enterprise.soap.sforce.com}Lead” 属性未解析为类型 定义。%

我的代码：

import logging
from spyne.model.primitive import Unicode, String, Integer64
from spyne.model.complex import ComplexModel
from spyne.service import ServiceBase
from spyne.decorator import rpc

class SObjectType(ComplexModel):
    __namespace__ = 'urn:sobject.enterprise.soap.sforce.com'
    __type_name__ = 'sObject'
    Id = String
    Company_ID__C = Integer64
    Company_Size_Text__c = Unicode

class NotificationType(ComplexModel):
    Id = Unicode
    sObject = SObjectType

class notificationsType(ComplexModel):
    __namespace__ = 'http://soap.sforce.com/2005/09/outbound'
    __type_name__ = 'notifications'
    OrganizationId = Unicode
    ActionId = Unicode
    SessionId = String(nillable="true")
    Notification = NotificationType.customize(max_occurs='100')

class SomeService(ServiceBase):

    @rpc(notificationsType)
    def MyMethod(ctx, notificationsType):
        print(notificationsType)

if __name__ == '__main__':
    from spyne.application import Application
    from spyne.protocol.soap import Soap11
    from spyne.server.wsgi import WsgiApplication
    from wsgiref.simple_server import make_server

    logging.basicConfig(level=logging.DEBUG)
    logging.info('listening to http://127.0.0.1:8080')

    application = Application([SomeService],
                          tns='http://soap.sforce.com/2005/09/outbound',
                          in_protocol=Soap11(validator='lxml'),
                          out_protocol=Soap11())

    wsgi_application = WsgiApplication(application)
    server = make_server('127.0.0.1', 8080, wsgi_application)
    server.serve_forever()

这是请求：

此答案是我已经想在这里向您解释的内容的补充： https：https：https：// github.com/arskom/spyne/discussions/686

您的服务定义是错误的。根据您的请求文档，您需要的内容如下：

class SomeService(ServiceBase):
    __tns__ = 'http://soap.sforce.com/2005/09/outbound'

    @rpc(sObject)
    def MyMethod(ctx, mymethodparam):
        print(mymethodparam)

至于您遇到的错误，实际上很清楚：

QName value '{urn:sobject.enterprise.soap.sforce.com}Lead' of the xsi:type attribute does not resolve to a type definition

您需要在“ urn：sobject.enterprise.soap.sforce.com）中拥有一个名为“ leds”的对象“名称空间。

以下片段意味着这是一个多态请求：

    <sObject xsi:type="sf:Lead" xmlns:sf="urn:sobject.enterprise.soap.sforce.com">

要解析多态性请求，您首先需要通过将polymorphic = true传递给入站协议实例化来启用它们。

然后，您需要定义系统将接受的所有可能类型。

在这种情况下，您至少需要Lead对象的定义。

class SObjectType(ComplexModel):
    __namespace__ = 'urn:sobject.enterprise.soap.sforce.com'
    __type_name__ = 'sObject'
    Id = String
    Company_ID__C = Integer64
    Company_Size_Text__c = Unicode


class Lead(SObjectType):
    __namespace__ = "urn:sobject.enterprise.soap.sforce.com"

    lead_field = Unicode

    # (...)
    # any additional fields that the lead object might have

据我所记得的，要为了注册为子类的类型，它必须在其定义上具有至少一个字段（这可能是一个错误或功能，取决于您的要求

）字段，无论如何，您需要在其定义中具有至少一个字段（在这种情况下称为Lead_field）。只要您的代码不使用它，它就无害。但是，如果您已经在铅定义中有其他字段，则不必拥有它。

工作！这是最终解决方案。

NS_C = "urn:sobject.enterprise.soap.sforce.com"

class sObjectType(ComplexModel):
    __namespace__ = NS_C
    Id = Unicode
    Company_ID__C = Integer64
    Company_Size_Text__c = String

class Lead(sObjectType):
    lead_field = Unicode
     
class NotificationType(ComplexModel):
    Id = Unicode
    sObject = sObjectType

NS_B = "http://soap.sforce.com/2005/09/outbound"

class OutboundMessagingService(ServiceBase):
    __namespace__ = NS_B
    @srpc(Unicode, NotificationType, sObjectType, _returns=notificationsResponseReturn)
    def notifications(tctx, Notification, sObject):
##. Do things here. 
application = Application([OutboundMessagingService], 
                            tns='http://soap.sforce.com/2005/09/outbound',
                            in_protocol=Soap11(),
                            out_protocol=Soap11())

wsgi_application = WsgiApplication(application)

谢谢Burak！
