Question

我有一个简单的REST服务端点，当我使用Fiddler 2 POST时失败。不需要输入参数的端点成功。只传入数据会导致失败。我正在使用集成到VS 2010中的Web服务器。

详细说明：

Global.asax条目：

private void Application_Start(object sender, EventArgs e)
        {
            RegisterRoutes();
        }
    private void RegisterRoutes()
        {
            RouteTable.Routes.Add(new ServiceRoute("Employee", new WebServiceHostFactory(), typeof(Employee)));
            RouteTable.Routes.Add(new ServiceRoute("Provider", new WebServiceHostFactory(), typeof(Provider)));
        }

网络服务：

[ServiceContract]
        [AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
        [ServiceBehavior(InstanceContextMode = InstanceContextMode.PerCall)]
        public class Provider : BaseMvpWebService<ProviderPresenter>, IProvider

    [WebInvoke(Method="POST", RequestFormat=WebMessageFormat.Json, UriTemplate="",      ResponseFormat=WebMessageFormat.Json, BodyStyle=WebMessageBodyStyle.Wrapped)]
        public ProviderListWrap FilteredList(GeneralSearchView filtersearch)
    { ... }

网络配置条目：

    <system.serviceModel>
        <standardEndpoints>
          <webHttpEndpoint>
        <!-- 
            Configure the WCF REST service base address via the global.asax.cs file and the default endpoint 
            via the attributes on the <standardEndpoint> element below
        -->
        <standardEndpoint name="" helpEnabled="true" automaticFormatSelectionEnabled="true"/>
      </webHttpEndpoint>
    </standardEndpoints>
    <behaviors>
      <serviceBehaviors>
        <behavior>
          <!-- To avoid disclosing metadata information, set the value below to false and remove the metadata endpoint above before deployment -->
          <serviceMetadata httpGetEnabled="true"/>
          <!-- To receive exception details in faults for debugging purposes, set the value below to true.  Set to false before deployment to avoid disclosing exception information -->
          <serviceDebug includeExceptionDetailInFaults="false"/>
        </behavior>
      </serviceBehaviors>
    </behaviors>
    <serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true" />
  </system.serviceModel>

参数类型定义：

 [DataContract]
 public class GeneralSearchView : IGeneralSearchView
 {
    [DataMember]
    public string ProviderListing { get; set; }

    [DataMember]
    public string FundingSource { get; set; }

    [DataMember]
    public string ProviderType { get; set; }

    [DataMember]
    public string ServiceType { get; set; }

    [DataMember]
    public string UserZipCode { get; set; }

    [DataMember]
    public string SearchRadius { get; set; }

    [DataMember]
    public string SearchCounty { get; set; }
 }

通过Fiddler 2发布：

POST  http://localhost:19099/Provider/

请求标题

User-Agent: Fiddler
Content-Type: application\json
Host: localhost:19099
Content-Length: 43

任何想法/反馈都将不胜感激。谢谢！

我认为您的内容类型斜杠可能存在语法问题。尝试：

Content-Type：application / json

如果没有，响应中是否还有其他详细信息？只有400个不好的请求？

Fiddler POST到REST服务端点出错400错误
