通过GitLabAPI查询SSHKey

Question

在java项目中通过gitlab-api1.2.5来查询GitLab里面的SSHKey，代码如下：

//通过Url和用户的privateToken创建连接
 GitlabAPI api = GitlabAPI.connect("http://192.168.99.100:10080/", "e7vrsYzzDZHPtSmnfQ3g");
 //通过SSHKey的ID查询SSHKey
 api.getSSHKey(2);

查询的时候出现以下异常

异常信息中看到，调用方法后返回的登录页面的html，然后被当做JSON进行解析，从而出现了异常。

之后尝试通过调用更据用户ID查询SSHKey的api，执行结果正常，能查询到SSHKey

 //通过用户ID查询用户的SSHKey
 api.getSSHKeys(7);

请问通过什么样的代码才能使用SSHKey的ID查询SSHKey信息？
