在开发环境运行一切正常，但是真机调试，或者上传为体验版运行，获取用户昵称永远得到“微信用户”。

<button bindtap="getUserProfile" disabled='{{btnDisabled}}'    class="btn"> 重新设置头像昵称 </button>

getUserProfile(e) {
    wx.getUserProfile({
      desc: '用于完善用户资料', 
      success: (res) => {
        console.log("getUserProfile success:", res)
      }
    })
  },

日志（res的值）：

getUserProfile success:
