WCF 服务错误 - 传入消息具有意外的消息格式 'Raw'。预期的消息格式为 'Xml' , 'Json'

Question

我想将 jason 格式的数据发送到 wcf 服务进行处理。开发了 Wcf 服务，当使用 fiddler 将 jason 输入发送到服务时，它会抛出错误 -
服务器在处理请求时遇到错误。异常消息是“传入消息具有意外消息格式“原始”。该操作的预期消息格式为“Xml”、“Json”。这可能是因为尚未在绑定(bind)上配置 WebContentTypeMapper。有关详细信息，请参阅 WebContentTypeMapper 的文档。有关更多详细信息，请参阅服务器日志。

Service contract
================

 public interface IRegisterEmployee
    {

        [OperationContract]
        [WebInvoke(Method = "POST", RequestFormat = WebMessageFormat.Json, BodyStyle=WebMessageBodyStyle.Bare, ResponseFormat=WebMessageFormat.Json, UriTemplate = "AddEmployee")]
        bool ProcessEmployee(Employee emp);
    }

   [DataContract]
    public class Employee
    {
        [DataMember]
        public string emp { get; set; } //this is actually a complex type, but simplified here

    }

Service class
============
public class RegisterEmployee : IRegisterEmployee
    {
        public bool ProcessEmployee(Employee emp)
        {
            //do some processing
            return true;

        }

Web.config
=========
<services>
      <service name="Project.RegisterEmployee">
        <endpoint address="Rest" behaviorConfiguration="RestfulBehavior" binding="webHttpBinding" name="Rest" contract="Project.IRegisterEmployee" />
        <endpoint address="Soap" behaviorConfiguration="" binding="basicHttpBinding" name="Soap" contract="Project.IRegisterEmployee" />
        <endpoint address="Mex" behaviorConfiguration="" binding="mexHttpBinding" name="Mex" contract="IMetadataExchange" />
        <host>
          <baseAddresses>
            <add baseAddress="http://localhost/Project" />
          </baseAddresses>
        </host>
      </service>
    </services>

    <endpointBehaviors>
        <behavior name="RestfulBehavior">
          <webHttp automaticFormatSelectionEnabled="true" />
        </behavior>
    </endpointBehaviors>

*Fiddler
======
POST;  http://localhost/Project/RegisterEmployee.svc/Rest/AddEmployee
Content-Type: application/jason
Request Body = {"emp" : "test"}*

Error - HTTP/1.1 400 Bad Request

如果我使用 wcftestclient( Debug模式)，它工作正常 - 猜测它使用的是 soap/xml。

Answer 1

请求的内容类型应为 application/ json ，而不是应用程序/杰森。尝试改变它，它应该工作。
