C# .NET核心API，如何使用“；内容类型”；用于‘；text/xml’；在联邦快递追踪API的HTTP帖子中

我想通过提交如下SOAP请求来进行Fedex跟踪API调用。 联邦快递网络服务最佳实践告诉我们，方法是HTTPPOST，内容类型应该是'text/xml'

我找不到任何相关的代码示例

我尝试了下面的代码。如果是HttpPost方法，则不进行调用。当我尝试使用HttpGet方法时，至少进行了调用并抛出错误

        [Produces("application/json", "application/xml")]
        [Route("api/fedex")]
        [ApiController]
        public class FedexController : BaseController
        {
            private readonly IConfiguration _config;
            public const SslProtocols _Tls12 = (SslProtocols)0x00000C00;
            public const SecurityProtocolType Tls12 = (SecurityProtocolType)_Tls12;
            public FedexController(IConfiguration config)
            {
                ServicePointManager.SecurityProtocol = Tls12;
                _config = config;
            }

    
            [HttpGet]
            [Route("GetFedexTrackingStatus/{trackingNumber}")]
            public IActionResult GetFedexTrackingStatus(int trackingNumber)
            {
                try
                {
                    string url = "https://wsbeta.fedex.com:443/web-services/track";

有人打过这些SOAPRequest电话吗？如何将XML作为输入传递
