状态500：调用WCF时System.ServiceModel.ServiceActivationException异常

问题描述：

我想从android客户端发送一个字符串到.NET服务器。以下是服务器端代码： - IService1.cs状态500：调用WCF时System.ServiceModel.ServiceActivationException异常

using System; 
using System.Collections.Generic; 
using System.Linq; 
using System.Runtime.Serialization; 
using System.ServiceModel; 
using System.ServiceModel.Web; 
using System.Text; 

namespace WcfImageUpload 
{ 
    // NOTE: You can use the "Rename" command on the "Refactor" menu to change the interface name "IService1" in both code and config file together. 
    [ServiceContract] 
    public interface IService1 
    { 
     [OperationContract] 
     [WebInvoke(UriTemplate = "/JsonData", 
       RequestFormat = WebMessageFormat.Json, 
       ResponseFormat = WebMessageFormat.Json, Method = "POST", 
       BodyStyle = WebMessageBodyStyle.WrappedRequest)] 
     JsonString SendData(JsonString JsonImage); 

     // TODO: Add your service operations here 
    } 

    // Use a data contract as illustrated in the sample below to add composite types to service operations. 
    [DataContract] 
    public class JsonString 
    { 
     [DataMember] 
     public string ImageData { get; set; } 
    } 
}

Service1.svc.cs

using System; 
using System.Collections.Generic; 
using System.Linq; 
using System.Runtime.Serialization; 
using System.ServiceModel; 
using System.ServiceModel.Web; 
using System.Text; 

namespace WcfImageUpload 
{ 
    // NOTE: You can use the "Rename" command on the "Refactor" menu to change the class name "Service1" in code, svc and config file together. 
    public class Service1 : IService1 
    { 
     public JsonString SendData(JsonString JsonImage) 
     { 
      JsonString jsonStringObject = new JsonString(); 
      jsonStringObject.ImageData = "ImageData"; 

      return jsonStringObject; 
     } 
    } 
}

的Web.config

<configuration> 
    <system.serviceModel> 
     <serviceHostingEnvironment multipleSiteBindingsEnabled="true"/> 
     <services> 
      <service behaviorConfiguration="Default" name="WcfImageUpload.Service1"> 
       <endpoint address="" behaviorConfiguration="webBehavior" binding="basicHttpsBinding" contract="WcfImageUpload.IService1" /> 
       <endpoint contract="IMetadataExchange" binding="mexHttpBinding" address="mex"/> 
      </service> 
     </services> 
     <behaviors> 
      <endpointBehaviors> 
       <behavior name="webBehavior"> 
        <webHttp helpEnabled="true"/> 
       </behavior> 
      </endpointBehaviors> 
      <serviceBehaviors> 
       <behavior name="Default"> 
        <serviceMetadata httpGetEnabled="true"/> 
       </behavior> 
       <behavior name=""> 
        <serviceMetadata httpGetEnabled="true"/> 
        <serviceDebug includeExceptionDetailInFaults="false"/> 
       </behavior> 
      </serviceBehaviors> 
     </behaviors> 
    </system.serviceModel> 
    <system.web> 
     <compilation debug="true"/> 
    </system.web> 
</configuration>

当我使用的是Chrome测试服务应用程序称为PostMan，我们得到以下错误： -

500 System.ServiceModel.ServiceActivationException

我试图发送格式的JSON -

{的ImageData：“测试字符串”}

可能是什么错误的原因是什么？

信息是怎么说的以及你如何解释这条信息？ – usr

消息说： - 500 System.ServiceModel.ServiceActivationException 我还没有解释的消息，我不知道它的意思，或者我应该从中推断出什么，如果你是一位专家善意地倾诉一些问题。 – Sreekanth

还有更多。每个异常都有一个堆栈跟踪和一条消息。你没有看到完整的例外。调试应用程序和/或启用WCF传输故障详细信息（http://msdn.microsoft.com/en-us/library/ff649234.aspx）。 – usr

答

同时运行SP2013 JSOM非同步功能

clientContext.executeQueryAsync(Function.createDelegate(this, OnQuerySuccess), Function.createDelegate(this, OnQueryFail));

我只是有这个问题，并通过重置IIS解决它。

只需以管理员身份打开Windows PowerShell并运行iisreset即可。

谢谢，我解决了这个问题。 – Nit
