我有一个ASP.NET Core v2.1项目，包含Swashbuckle.AspNetCore包。我的代码是：

/// <summary>
    /// Set new android token for the current driver
    /// </summary>
    /// <remarks>
    /// Sample request:
    ///
    ///     PUT /SetToken?token=new_token
    ///
    /// </remarks>
    /// <param name="token">can't be null or empty</param>
    /// <returns></returns>
    /// <response code="204">If executed successfully</response>
    /// <response code="400">if token is null or empty</response>  
    /// <response code="404">if user is not a driver; if driver is not found (removed etc); if user does not have a profile</response>  
    [ProducesResponseType(204)]
    [ProducesResponseType(400)]
    [ProducesResponseType(404)]
    [HttpPut]
    [Route("SetToken")]
    [UserIsNotDriverException]
    [NullReferenceException]
    [DriverWithoutProfileException]
    public async Task<IActionResult> SetToken([FromQuery]string token)
    {

字符串
我想将查询参数标记为必需的。我该怎么做呢？注意，我在查询字符串中传递参数，而不是在主体中传递参数
