CRM 2011 查找並判斷用戶是否有該角色

注意：用戶須要安全角色讀的權限，

function onLoad() {
    CurrentUserHasRole('系統管理員'); //有則是TRUE
}

//功能說明: 獲取當前用戶是否具備該角色
//備註：               
//參數說明：
//          roleName: 角色名稱
//返回值說明（return）：
//          bool:
function CurrentUserHasRole(roleName) {
    //爲了不OData中文檢索不出這種問題，使用encodeURIComponent來encode；
    var serverUrl = Xrm.Page.context.getClientUrl();
    var curUserId = Xrm.Page.context.getUserId();
    var retrieveEntityReq = RetrieveEntityRecordByGuid("SystemUser", curUserId);
    retrieveEntityReq.send();
    if (retrieveEntityReq.status == 200) {
        var retrieved = JSON.parse(retrieveEntityReq.responseText).d;
        var oDataEndpointUrl = serverUrl + "/XRMServices/2011/OrganizationData.svc/";
        oDataEndpointUrl += "RoleSet?$filter=Name eq " + "'" + encodeURIComponent(roleName) + "'" + " and BusinessUnitId/Id eq (guid'" + retrieved.BusinessUnitId.Id + "')";

        var service = new XMLHttpRequest();
        if (service != null) {
            service.open("GET", oDataEndpointUrl, false);
            service.setRequestHeader("Accept", "application/json");
            service.setRequestHeader("Content-Type", "application/json; charset=utf-8");
            service.send(null);

            var requestResults = eval('(' + service.responseText + ')').d;
            if (requestResults != null && requestResults.results.length == 1) {
                var role = requestResults.results[0];
                var id = role.RoleId;
                var currentUserRoles = Xrm.Page.context.getUserRoles();
                for (var i = 0; i < currentUserRoles.length; i++) {

                }
            }
        }
        return false;
    }
}


//功能說明: 比較兩個Guid
//備註：               
//參數說明（Parameters）：
//         guid1：Guid
//         guid2: Guid
//返回值說明（return）：
//          bool:
