Question

我已将此代码提交给服务器：

var obj = { "param": { "WithdrawalRequestId": window.Xrm.Page.data.entity.getId()} };
    $.ajax({
        type: "POST",
        dataType: "json",   
        data: JSON.stringify(obj),

        url: crmConfig.service + '/WithdrawRequestService.svc/ExecuteWithdrawalRequests/',

    });

转到服务器的实际内容是：

{"param":{"WithdrawalRequestId":"{628E2E3A-283A-E311-B658-005056B7032A}"}}

界面：

 [OperationContract]
        [WebInvoke(Method = "POST",
            RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json,
            BodyStyle = WebMessageBodyStyle.Wrapped,
            UriTemplate = "/ExecuteWithdrawalRequests/")]
        void ExecuteWithdrawalRequests(GuidParameter param);

GuidParameter类：

[DataContract]
public class GuidParameter
{
    [DataMember]
    public Guid WithdrawalRequestId { get; set; }

}

我收到以下错误：

The server encountered an error processing the request.

异常消息是'传入消息具有意外的消息格式'Raw' 操作的预期消息格式是'Xml'，'Json'。这可能是因为尚未在绑定上配置WebContentTypeMapper 有关更多详细信息，请参阅WebContentTypeMapper的文档。

这是chrome输出：

Answer 1

添加contentType: "application/json,

var obj = { "param": { "WithdrawalRequestId": window.Xrm.Page.data.entity.getId()} };
    $.ajax({
        type: "POST",
        dataType: "json",   
        data: JSON.stringify(obj),
        contentType: "application/json",
        url: crmConfig.service + '/WithdrawRequestService.svc/ExecuteWithdrawalRequests/',

    });
