CRM身份验证问题

如何在JavaScript中包含GenerateAuthenticationHeader（）。我需要包括哪些必要的DLL？我使用这个函数来检索使用JavaScript的MS CRM实体。我得到这个错误：

Microsoft JScript运行时错误："GenerateAuthenticationHeader"未定义

function AccessCRMWebServices() {
        debugger;
        var auth = GenerateAuthenticationHeader();
                    var productCode = "ABCDE";
                    var stock;
                    var x = Xrm.Page.getAuthenticationHeader();
