无法在发布 WCF 请求 .NET C# 中接收“\”字符

Question

{ "string001Value":"LITTELFUSE \\/ 772291851034","string002Value":"772291851034","string003Value":"","string004Value":""... }

当发送一个 Json 对象时，WCF 服务会在不使用反斜杠 '' 的情况下接收它，string001Value 属性会接收到“LITTELFUSE / 772291851034”的值。

如何在服务中接收此类字符，使其值为“LITTELFUSE \ / 772291851034”？

这是 WebInvoke 方法：

[OperationContract]
[WebInvoke(Method = "POST", BodyStyle = WebMessageBodyStyle.Bare, 
           RequestFormat = WebMessageFormat.Json, 
           ResponseFormat = WebMessageFormat.Json, 
           UriTemplate = "warehouse_shipping_advice")]
_ResponseDetail WarehouseShippingAdvice(_WarehouseShipping newWarehouseShipping);

根据你的描述，我做了测试，没有发现问题，这里是我的demo：

 [ServiceContract]
    public interface IService1
    {
        [WebInvoke(Method = "POST", BodyStyle = WebMessageBodyStyle.Bare,
            RequestFormat = WebMessageFormat.Json,
            ResponseFormat = WebMessageFormat.Json,
            UriTemplate = "warehouse_shipping_advice")]
        void WarehouseShippingAdvice(_WarehouseShipping newWarehouseShipping);
    }
    [DataContract]
    public class _WarehouseShipping
    {
        [DataMember]
        public string string001Value { get; set; }
    }
    public class Service1 : IService1
    {
        public void WarehouseShippingAdvice(_WarehouseShipping newWarehouseShipping)
        {
            Console.WriteLine(newWarehouseShipping.string001Value);
        }
    }
    class Program
    {
        static void Main(string[] args)
        {
            // Step 1: Create a URI to serve as the base address.
            Uri baseAddress = new Uri("http://localhost:8000/GettingStarted/");

            // Step 2: Create a ServiceHost instance.
            ServiceHost selfHost = new ServiceHost(typeof(Service1), baseAddress);

            try
            {
                // Step 3: Add a service endpoint.
                selfHost.AddServiceEndpoint(typeof(IService1), new WebHttpBinding(), "CalculatorService").Behaviors.Add(new WebHttpBehavior() { HelpEnabled=true});

                // Step 4: Enable metadata exchange.
                ServiceMetadataBehavior smb = new ServiceMetadataBehavior();
                smb.HttpGetEnabled = true;
                selfHost.Description.Behaviors.Add(smb);

                // Step 5: Start the service.
                selfHost.Open();
                Console.WriteLine("The service is ready.");

                // Close the ServiceHost to stop the service.
                Console.WriteLine("Press <Enter> to terminate the service.");
                Console.WriteLine();
                Console.ReadLine();
                selfHost.Close();
            }
            catch (CommunicationException ce)
            {
                Console.WriteLine("An exception occurred: {0}", ce.Message);
                selfHost.Abort();
            }
        }
    }

这是我的服务。我在服务中启用了帮助文档。

根据帮助文档，我们可以正确请求服务。
