autodesk forge测试官网案例，后台报错

Question

问题描述

初次练习forge，按照官网http://learnforge.autodesk.io...，选择的是java，在eclipse上运行的，都是按照官网上的步骤进行，当输入http://localhost:3000时，后台出现错误如下
get buckets & objects exception: java.lang.RuntimeException: Expected 200 but got 400, with body {"developerMessage":"The required parameter(s) client_id,client_secret not present in the request","userMessage":"","errorCode":"AUTH-008","more info":"http://developer.api.autodesk.com/documentation/v1/errors/AUTH-008"}
望大佬给解决下，谢谢。
