开启xpack后， bigdesk无法访问

es是6.5.1，本来bigdesk还能用。但是集群启用xpack后就无法使用。
于是找到了这篇文章http://www.programmersought.co ... 6225/
修改bigdesk-master / _site / js / util / bigdesk_extension.js 

    sync: function(method, model, options) {

        //options.dataType = 'jsonp';

        options.url = this.getBaseUrl() + this.url();

       // Append Authorization request header 

  // ZWxhc3RpYzpjaGFuZ2VtZQ ​​== is user: base64 encrypted value of the password

         options.beforeSend = function (xhr) {

             xhr.setRequestHeader('Authorization', 'Basic ZWxhc3RpYzpjaGFuZ2VtZQ==');

        }

        return Backbone.sync(method, model, options);

    }

但是我修改后，依旧不能用，有没有大神指点一下

Backbone.Collection = Backbone.Collection.extend({

    sync: function(method, model, options) {

       // options.dataType = 'jsonp';

       // options.url = this.getBaseUrl() + this.url();



  //----------------------修改的地方

       options.beforeSend = function (xhr) {

          xhr.setRequestHeader('Authorization', 'Basic ZWxhc3RpYzoxMjM0NTY=');

        }



 //----------------------修改的地方

        return Backbone.sync(method, model, options);

    },

    // Did not find much information about how to store metadata with collection.

    // Direct set/get of property seems to work fine.

    getBaseUrl: function() {

        return this.baseUrl;

    },

    setBaseUrl: function(url) {

        this.baseUrl = url;

    },

    initialize: function(models, options) {

        if (options && options.baseUrl) {

            this.setBaseUrl(options.baseUrl);

        }

    }

});
