是否可以通过加电方式获取当前板卡的当前ID？

我的client.js

var Promise = TrelloPowerup.Promise;

TrelloPowerup.initialize({
    // Start adding handlers for your capabilities here!
  'current-board': function(t,options){
    console.log(boardId) // I want to get the board's Id
  },'card-buttons': function(t,options) {
    return t.set("member","shared","hello","world")
    .then(function(){
        return [{
        icon: BLACK_rocket_ICON,text: 'Estimate Size',callback: function(t) {
                return t.popup({
                  title: "Estimation",url: 'estimate.html',});
              }
            }];
    })
    },});

开机初始化时，我要控制台记录board Id。
