我需要使用一个使用WS-Security的SOAP 1.2 Web服务。我在工作中使用的平台是Delphi 10.2 Tokyo和.Net Core。这些似乎都不起作用。
在尝试使用Delphi 10.2 Tokyo的内置WSDL导入程序（将SOAP 1.2与Indy结合使用）时，发送的请求没有任何SOAP标头信息。此无效请求会引发错误对等方重置连接。
尝试使用.Net Core（使用WCF Web服务引用提供程序）时出现错误： System.PlatformNotSupportedException：'不支持TransportSecurityBindingElement.BuildChannelFactoryCore。'
大概是由于.Net Core尚不支持所需的功能：https://github.com/dotnet/wcf/blob/master/release-notes/SupportedFeatures-v2.0.0.md（不支持Security.Message）
下面是WSDL。我已从该文件中修剪了不必要的XML，并用Example替换了实际的公司名称。希望这将使您对WSDL策略/要求有足够的了解。

没有特定的“最佳”平台可以使用Web服务。 但是，某些平台比其他平台更好地支持自动生成代理类。
在尝试使用Delphi 10.2 Tokyo的内置WSDL导入程序（将SOAP 1.2与Indy结合使用）时，发送的请求没有任何SOAP标头信息。
我没有使用.NET Core的经验，但是在使用Delphi 10.2时，您需要在发送请求之前手动添加（发送）SOAP标头。
这可以通过将网络服务实例投射到ISOAPHeaders
示例：
procedure TestSendHeader;
var
MyService: IMySoapWebservice;
header : TMySoapHeader;
begin
MyService := GetMySoapService();
(MyService as ISOAPHeaders).OwnsSentHeaders := True;
// Create header object
header := TMySoapHeader.Create;
// Fill header data
// header.xyz := ;
// 'Send' header with the request
(MyService as ISOAPHeaders).Send(header);
MyResponse := MyService.DoMyRequest();
end;
在发送请求之后，将OwnsSentHeaders设置为true将会释放所创建的标头对象。
注意：每次发出请求时，您都必须“发送”标头：
// 'Send' header with the request 1
(MyService as ISOAPHeaders).Send(header);
MyResponse := MyService.DoMyRequest1();
// 'Send' header with the request 2
(MyService as ISOAPHeaders).Send(header);
MyResponse := MyService.DoMyRequest2();
在这种情况下，请勿在完成发送请求后将OwnsSentHeaders设置为true并释放标题对象。

.NET Framework完全支持SOAP服务。我已经用C＃开发了一个.NET Framework应用程序，并构建了一个可以供Delphi，.NET Core等使用的DLL。这是一个a回的解决方案，但我能找到的最简单的解决方案。
使用C＃访问服务：https://docs.microsoft.com/en-us/dotnet/framework/wcf/accessing-services-using-a-wcf-client
导出DLL函数：Is is possible to export functions from a C# DLL like in VS C++?
