我正在尝试设置将由 .NET 应用程序使用的 SAP Web 服务。认为这很简单,我在 SAP 中设置了服务以使用 HTTP。我在 .NET 项目树中右键单击“服务引用”,然后选择“添加服务引用...”,输入本地托管在我们服务器上的 WSDL URL,然后按 Go,然后选择端点,然后按 OK .
我打开 app.config 文件发现它说<httpsTransport>
而不是<httpTransport>
,尽管我将它设置为使用 HTTP。
<system.serviceModel>
<bindings>
<customBinding>
<binding name="ZHR_RECRUITNEW1">
<!--WsdlImporter encountered unrecognized policy assertions in ServiceDescription 'urn:sap-com:document:sap:soap:functions:mc-style':-->
<!-- <wsdl:binding name='ZHR_RECRUITNEW'> -->
<!-- <wsaw:UsingAddressing xmlns:wsaw="http://schemas.xmlsoap.org/ws/2004/08/addressing">..</wsaw:UsingAddressing> -->

<textMessageEncoding maxReadPoolSize="64" maxWritePoolSize="16"

maxBytesPerRead="4096" maxNameTableCharCount="16384" />
</textMessageEncoding>
<httpsTransport manualAddressing="false" maxBufferPoolSize="524288"
maxReceivedMessageSize="65536" allowCookies="false" authenticationScheme="Anonymous"
bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard"
keepAliveEnabled="true" maxBufferSize="65536" proxyAuthenticationScheme="Anonymous"
realm="" transferMode="Buffered" unsafeConnectionNtlmAuthentication="false"
useDefaultWebProxy="true" requireClientCertificate="false" />
</binding>
</customBinding>
</bindings>
<client>
<endpoint address="http://<host>:8000/sap/bc/srt/rfc/sap/zhr_recruitnew/300/zhr_recruitnew/zhr_recruitnew"
binding="customBinding" bindingConfiguration="ZHR_RECRUITNEW1"
contract="ServiceReference2.ZHR_RECRUITNEW" name="ZHR_RECRUITNEW1" />
</client>
</system.serviceModel>
因此,为了“正常”工作,我必须将该 xml 标记从 httpsTransport 重命名为 httpTransport 并删除属性 requireClientCertificate="false"
因此,我进入 SAP 设置服务以使用 HTTPS,然后返回 .NET 项目并重新添加该服务,以获取以下错误消息:
Could not establish trust relationship for the SSL/TLS secure channel with authority '<host>:<portnumber>'.
我很好奇配置文件中的评论“WsdlImporter 遇到无法识别的策略断言”是否与从 SAP 误读的信息有关
