How to use the iview.Message function in iview

res => {
    const apiRes = res.data
    switch (+apiRes.code) {
      case codeStatus.NOTFOUND:
        document.title = '404 - 找不到页面'
        flag && iView.LoadingBar.error()
        // 可以在这里直接设置跳转到 404 页面，已经不需要啦，在组件中已经设置，为了不改变 url，实现转发的效果
        // router.push({name: 'error'})
        break
      case codeStatus.UNAUTHORIZED:
        store.dispatch('user/CLEARUSER')
        sessionStorage.clear()
        iView.Message.error(apiRes.message)
        flag && iView.LoadingBar.finish()
        router.push({name: 'login'})
        break
      default:
        flag && iView.LoadingBar.finish()
        break
    }
    return apiRes
  },
  async error => {

      // 403 状态执行页面跳转，其余状态不跳转
      if (error.response.status === 403) {
