Question

我正在尝试从SAP上的.NET环境中使用webservices。但是当我尝试在SAP SOAMANAGER中创建逻辑端口时，我收到错误：

SRT-Framework-Ausnahme：Initialer Wert“消费者上下文表” Methode IF_SRT_WSP_CONFIG_REGISTRY~CREATE_CONTEXTS_FROM_WS der Klasse CL_SRT_WSP_CONFIG_REGISTRY

WSDL-Analyzer显示 2个不支持的元素：

<http:BasicAuthentication xmlns:http="http://schemas.microsoft.com/ws/06/2004/policy/http" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" xmlns:wsap="http://schemas.xmlsoap.org/ws/2004/08/addressing/policy" xmlns:wsa10="http://www.w3.org/2005/08/addressing" xmlns:tns="http://tempuri.org/" xmlns:msc="http://schemas.microsoft.com/ws/2005/12/wsdl/contract" xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/" xmlns:wsx="http://schemas.xmlsoap.org/ws/2004/09/mex" xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:wsam="http://www.w3.org/2007/05/addressing/metadata" xmlns:wsa="http://schemas.xmlsoap.org/ws/2004/08/addressing" xmlns:wsp="http://schemas.xmlsoap.org/ws/2004/09/policy" xmlns:wsaw="http://www.w3.org/2006/05/addressing/wsdl" xmlns:soap12="http://schemas.xmlsoap.org/wsdl/soap12/" xmlns:wsu="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd" xmlns:xsd="http://www.w3.org/2001/XMLSchema"/>

和

<sp:TransportBinding xmlns:sp="http://schemas.xmlsoap.org/ws/2005/07/securitypolicy" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" xmlns:wsap="http://schemas.xmlsoap.org/ws/2004/08/addressing/policy" xmlns:wsa10="http://www.w3.org/2005/08/addressing" xmlns:tns="http://tempuri.org/" xmlns:msc="http://schemas.microsoft.com/ws/2005/12/wsdl/contract" xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/" xmlns:wsx="http://schemas.xmlsoap.org/ws/2004/09/mex" xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:wsam="http://www.w3.org/2007/05/addressing/metadata" xmlns:wsa="http://schemas.xmlsoap.org/ws/2004/08/addressing" xmlns:wsp="http://schemas.xmlsoap.org/ws/2004/09/policy" xmlns:wsaw="http://www.w3.org/2006/05/addressing/wsdl" xmlns:soap12="http://schemas.xmlsoap.org/wsdl/soap12/" xmlns:wsu="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd" xmlns:xsd="http://www.w3.org/2001/XMLSchema"><wsp:Policy xmlns:wsu="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd" xml:base="https://external-server.com/Webservice.svc?singlewsdl"><wsp:ExactlyOne><wsp:All><sp:TransportToken><wsp:Policy xml:base="https://external-server.com/Webservice.svc?singlewsdl"><wsp:ExactlyOne><wsp:All><sp:HttpsToken RequireClientCertificate="false"/></wsp:All></wsp:ExactlyOne></wsp:Policy></sp:TransportToken><sp:AlgorithmSuite><wsp:Policy xml:base="https://external-server.com/Webservice.svc?singlewsdl"><wsp:ExactlyOne><wsp:All><sp:Basic256/></wsp:All></wsp:ExactlyOne></wsp:Policy></sp:AlgorithmSuite><sp:Layout><wsp:Policy xml:base="https://external-server.com/Webservice.svc?singlewsdl"><wsp:ExactlyOne><wsp:All><sp:Strict/></wsp:All></wsp:ExactlyOne></wsp:Policy></sp:Layout></wsp:All></wsp:ExactlyOne></wsp:Policy></sp:TransportBinding>

所以我详细查看了WSDL文件，删除了wsp：All标签的内容，即：

            <http:BasicAuthentication xmlns:http="http://schemas.microsoft.com/ws/06/2004/policy/http"/>
            <sp:TransportBinding xmlns:sp="http://schemas.xmlsoap.org/ws/2005/07/securitypolicy">
                <wsp:Policy>
                    <sp:TransportToken>
                        <wsp:Policy>
                            <sp:HttpsToken RequireClientCertificate="false"/>
                        </wsp:Policy>
                    </sp:TransportToken>
                    <sp:AlgorithmSuite>
                        <wsp:Policy>
                            <sp:Basic256/>
                        </wsp:Policy>
                    </sp:AlgorithmSuite>
                    <sp:Layout>
                        <wsp:Policy>
                            <sp:Strict/>
                        </wsp:Policy>
                    </sp:Layout>
                </wsp:Policy>
            </sp:TransportBinding>

从已编辑的离线WDSL文件创建逻辑端口现在可以使用！所以我猜，问题起源于BasicAuthentication和TransportBinding标签。

当然原始的外部WDSL文件必须进行调整。

为了生成SAP兼容的WSDL文件，我需要在.NET环境中进行哪些更改？我是否必须调整web.config文件？

Answer 1

ABAP Web服务客户端功能支持的WSDL元素存在一些限制。有记录说明了支持和不支持的内容：

944029 - ABAP代理生成支持的XML架构
1327511 - ABAP WSDL处理中的限制和常见问题

在这种情况下，您有两种解决方案：

如果可能，请让Web服务发布者修改其服务以删除任何不受支持的元素。在大多数情况下，这是不可能的。
修改WSDL以删除任何不受支持的元素。不幸的是，这可能非常棘手，并且每次WSDL更改时都需要完成（从第一次更改后的差异开始可能可能，但可能会比它的价值更麻烦）。

如何更改.NET WSDL以使其与SAP兼容？
