webapi用Swashbuckle.AspNetCore报Internal Server Error /swagger/v1/swagger.json错误，解决

解决办法
必须要将所有的action方法头都要加上Rote，比如[HttpPost(“TargetSourse”)]，此处为简写

参考代码

    [Route("[controller]")]
    public class ChartDataController : Controller
    {
        /// <summary>
        /// 获取各个指标的源数据
        /// </summary>
        /// <returns></returns>
        [HttpPost("TargetSourse")]
        [TokenFilter]
        public async Task<ActionResult> TargetSourse([FromBody]TargetParames parames)
        {
        //方法体
        }
