WCF jquery parsererror未终止的字符串常量响应

对于我最近的项目，我创建了一个Web服务，它将自定义类型的数组返回给jquery客户端代码。 WCF通过$.ajax命令调用，并位于同一个域中。WCF jquery parsererror未终止的字符串常量响应

当我在localhost上运行我的web应用程序（这是在本地机器上运行的IIS）时，一切正常。当我将它部署到我们的集成服务器时，突然ajax调用WCF结束时出现错误：“parsererror - 未终止的字符串常量”，状态为200.然而，返回的消息类似于"[{\"Text\":\"Test dodatnih naslov"，这当然不是正确的json格式。

正确反应应该是："[{"Text":"Test dodatnih naslovov","Value":"100"},{"Text":"Test dodatnih naslovov - ISO2","Value":"101"},{"Text":"UPDATE","Value":"102"}]"

我已经追踪WCF服务malfuncitons，但它似乎并没有被撞毁。我也试过并设置了超时给ajax调用，但无济于事。一些帮助将不胜感激。

我的IIS是IIS7，其中积分IIS6运行在Windows Server 2008上

JS文件

function InsuranceClientContact_ItemsRequesting(o, e) { 
    var $ = $telerik.$; 
    var urlSvc = ServiceBaseUrl + '/GetContacts' 
    $.ajax({ 
     type: "POST", 
     url: urlSvc, 
     data: '{"ixClient": ' + selectedItemId + '}', //selectedItemId is a positive number 
     dataType: "json", 
     contentType: "application/json; charset=utf-8", 
     success: function (data) { 
      // do something 
     }, 
     error: function (result) { 
      var msg = result.status + " - " + result.statusText; 
      setTimeout(function() { throw new Error(msg) }, 0); 
     } 
    });

WCF接口

namespace Sid.Skode.Web.Services.Populate { 
    [ServiceContract] 
    public interface IInsuranceClientContactService { 
     [OperationContract] 
     [WebInvoke(Method="POST", 
      BodyStyle=WebMessageBodyStyle.WrappedRequest, 
      ResponseFormat=WebMessageFormat.Json)] 
     Contact[] GetContacts(long ixClient); 
    } 

    [DataContract] 
    public class Contact { 
     [DataMember] 
     public string Text; 
     [DataMember] 
     public string Value; 
    } 

}

WCF服务实现

namespace Sid.Skode.Web.Services.Populate { 
    [AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)] 
    public class InsuranceClientContactService : IInsuranceClientContactService { 

     public Contact[] GetContacts(long ixClient) { 
      return GetContactsFromDatabase(ixClient); 
     } 

     #region Private methods 

     private Contact[] GetContactsFromDatabase(long ixClient) { 
      DataTable dt = GetDataFromDataBaseById(ixClient); 
      return ConvertDataTableToContactArray(dt); 
     }   

     private DataTable GetDataFromDataBaseById(long ixClient) { 
      AutoCompleteBLL model = new AutoCompleteBLL(); 
      return model.SearchContactsByPartner(ixClient); 
     } 

     private Contact[] ConvertDataTableToContactArray(DataTable dt) { 
      Contact[] rgContact = new Contact[dt.Rows.Count]; 
      int cnContact = 0; 
      foreach (DataRow dr in dt.Rows) { 
       if (!dr.IsNull("NAZIV")) { 
        Contact contact = new Contact(); 
        contact.Text = dr["NAZIV"].ToString(); 
        contact.Value = dr["ID_DODATEN_KONTAKT"].ToString(); 
        rgContact[cnContact++] = contact; 
       } 
      } 
      return rgContact; 
     } 

     #endregion 

    } 
}

如上所述here，你需要从网络配置中删除RadCompression HTTP模块的所有实例。然后，它的工作。
