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/',

    });

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“传入消息具有意外消息格式“原始”。
该操作的预期消息格式为“Xml”、“Json”。这可能是因为尚未在绑定上配置 WebContentTypeMapper。
有关详细信息，请参阅 WebContentTypeMapper 的文档。

这是铬输出：

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/',

    });

如果您是初学者，那么这将指导您创建支持 json 和 xml 的 Web 服务，供以下用户使用：

更新：

WCF“原始”编程模型（Web） - 接收任意数据

或者
