        RESTHelper.prototype.Read = function (id) {

            var req = new XMLHttpRequest();            

           var baseurl = "/" + Xrm.Page.context.getOrgUniqueName();   

           queryurl = baseurl + "/xrmservices/2011/OrganizationData.svc/UserSet?$filter=Id/Id eq guid'"+id+"'";//此句话要修改（是你要查询的实体使用工具）

 

            req.open("GET", queryurl, false);

            req.setRequestHeader("Content-Type", "application/json; charset=utf-8");

            req.setRequestHeader("Content-Length", 0);
