api調用Swashbuckle.AspNetCore报Internal Server Error /swagger/v4/swagger.json错误

https://blog.csdn.net/u011511086/article/details/80371896

我是用樓上的方法解決的，我的Swashbuckle是v4版本的，用vs2017開發的

下面是我的代碼，不過我的Controller繼承的是ControllerBase

 

 [Route("api/[controller]")]
    //[Route("api/[controller]/[action]")]
    [ApiController]
    public class ValuesController : ControllerBase
    {

        /// 

        / 獲取所有線體
        / 
        / 
        [HttpGet("TargetSource")] 
        public dynamic GetLineList()
        {
            return Ok("");
        }
        // GET api/values 
        [HttpGet]        
        public ActionResult> Get()
        {
            return new string[] { "value1", "value2" };
        }

        // GET api/values/5
        [HttpGet("{id}")]
        public ActionResult Get(int id)
        {
            return "value";
        }

        // POST api/values
        [HttpPost]
        public void Post([FromBody] string value)
        {
        }

        // PUT api/values/5
        [HttpPut("{id}")]
        public void Put(int id, [FromBody] string value)
        {
        }

        // DELETE api/values/5
        [HttpDelete("{id}")]
        public void Delete(int id)
        {
        }
    }

報錯情況有

1。在方法前面缺少[HttpPost]（Put,Get等）

2。 當有多個[HttpPost]時，要用[Route("api/[controller]/[Action]")]

 [Route("api/[controller]/[Action]")]
 [Route("api/[controller]")]
