Ajax调用WCF返回错误

我收到了错误:

  

异常消息是'传入消息有意外消息   消息格式'Raw'。操作的预期消息格式   是'Xml','Json'。这可能是因为WebContentTypeMapper没有   已在绑定上配置。请参阅文档   WebContentTypeMapper获取更多详细信息。'。请参阅服务器日志了解更多   的信息。

我正在对WCF服务进行ajax调用,如下所示:

function WCFJSON() {
var now = new Date();

var getFromDate = dateToWcf(new Date(now - (60000 * 1440)));

var userid = "1";
m_Type = "POST";
m_Url = "https://dev-04.boldgroup.int/ManitouDashboard/DashboardProxyService.svc/GetStats"
m_Data = "{'fromdate':'" + getFromDate + "'getvaluelist':'[1,2,3]'}";
m_DataType = "json";
m_ProcessData = true;             
CallService();
}

function dateToWcf(input) {
var d = new Date(input);
if (isNaN(d)) {
    throw new Error("input not date");
}
var date = '\\\/Date(' + d.getTime() + '-0000)\\\/';
return date;
}

function CallService() {
$.ajax({
    type: m_Type,           //GET or POST or PUT or DELETE verb                  
    url: m_Url,                 //Location of the service   
    data: m_Data,
    dataType: m_DataType,   //Expected data format from server                  
    processdata: m_ProcessData, //True or False
    crossdomain: true,    
    contentType: "application/json",             
    success: function (msg) {   //On Successfull service call                      
        ServiceSucceeded(msg);
    },
    error: function (jqXHR, textStatus, errorThrown) {
        ServiceFailed("jqXHT: " + jqXHR.result + "Text Status: " + textStatus + " Error Thrown: " + errorThrown );
    } // When Service call fails              
});
}

我的服务合同声明如下:

[ServiceContract]
public interface IDashboardWCFService
{
    [OperationContract]
    [WebInvoke(UriTemplate = "GetStats", ResponseFormat = WebMessageFormat.Json, BodyStyle = WebMessageBodyStyle.Wrapped)]
    Dictionary<int,List<StatValue>> GetStats(DateTime getFromDate, List<int> getValueList);

    [OperationContract]
    [WebGet(UriTemplate = "GetStatTypes", ResponseFormat = WebMessageFormat.Json)]
    List<StatType> GetStatTypes();
}

我在通话中做错了吗?

1 个答案:

答案 0 :(得分:1)

  1. m_Data似乎有错误。两个项目之间没有逗号 (m_Data =“{'fromdate':'”+ getFromDate +“'getvaluelist':'[1,2,3]'}”;)
  2. 匹配参数名称(fromdate - &gt; getFromDategetvaluelist - &gt; getValueList
  3. 使用ISO 8601日期时间格式(2012-08-15T00:00:00 + 02:00)(我总是使用XDate作为日期/时间,它会踢屁股)
  4. 删除额外的刻度以防万一,并使用JSON.stringify
  5. m_Data = JSON.stringify({
      getFromDate: "'" + getFromDate + "'",
      getValueList: [1,2,3]
    });
