如何使用api获取gitlab里程碑

Question

无论项目如何，我都需要获取gitlab里程碑列表 我尝试将下面的代码与提示的用户凭据一起使用

curl --header "PRIVATE-TOKEN: <your_access_token>" https://gitlab.example.com/api/v4/projects/:id/milestones

我得到了结果

{
  "message": "401 Unauthorized"
}

但是我需要的是

[
  {
    "id": 12,
    "iid": 3,
    "group_id": 16,
    "title": "Sample10.0",
    "description": "Version",
    "due_date": "2013-11-29",
    "start_date": "2013-11-10",
    "state": "active",
    "updated_at": "2013-10-02T09:24:18Z",
    "created_at": "2013-10-02T09:24:18Z"
  }
]
