Fakebook 主题

[Don]

你好，

我在 Fakebook 和现代 Fakebook 主题中遇到了问题，位于右侧边栏。此脚本不应加载给未登录的访客。有什么办法可以让此脚本仅对已登录用户加载吗？谢谢

<!-- 自定义侧边栏小部件 -->

<script type="text/discourse-plugin" version="0.8">
  const ajax = require('discourse/lib/ajax').ajax;

  let currentUser = Discourse.User.currentProp('username');

  api.registerConnectorClass('discovery-below', 'sidebar', {
    setupComponent(args, component) {
      ajax("/u/" + currentUser + "/summary.json").then (function(result){

        stinkinBadges = [];

        userLikesReceived = result.user_summary.likes_received;
        userLikesGiven = result.user_summary.likes_given;

        result.badges.forEach(function(badges){
          stinkinBadges.push(badges);
        });

        component.set('userLikesReceived', userLikesReceived);
        component.set('userLikesGiven', userLikesGiven);
        component.set('stinkinBadges', stinkinBadges);
        component.set('userName', api.getCurrentUser().name);
        component.set('user', api.getCurrentUser().username);

      });

    }

  });
</script>

错误代码如下：
