asp.net-core - ASP.NET 核心 3.0 : CreatedAtRoute: No route matches the supplied values

Question

从 2.2 更新到 ASP.NET Core 3.0 后，我收到错误消息:

No route matches the supplied values

这在执行 CreateAsync() 后立即出现.它由 CreatedAtAction() 触发方法。我试图设置 GetByIdAsync()的属性为 [HttpGet("{id}", Name = "Get")] ，但没有成功。我检查了其他相关线程，但我的代码看起来不错。

// GET: api/Bots/5
[HttpGet("{id}")]
public async Task<ActionResult<BotCreateUpdateDto>> GetByIdAsync([FromRoute] int id)
{
  var bot = await _botService.GetByIdAsync(id);

  if (bot == null)
  {
    return NotFound();
  }

  return Ok(_mapper.Map<BotCreateUpdateDto>(bot));
}

// POST: api/Bots
[HttpPost]
public async Task<ActionResult<BotCreateUpdateDto>> CreateAsync([FromBody] BotCreateUpdateDto botDto)
{
  var cryptoPair = await _botService.GetCryptoPairBySymbolAsync(botDto.Symbol);

  if (cryptoPair == null)
  {
    return BadRequest(new { Error = "Invalid crypto pair." });
  }

  var timeInterval = await _botService.GetTimeIntervalByIntervalAsync(botDto.Interval);

  if (timeInterval == null)
  {
    return BadRequest(new { Error = "Invalid time interval." });
  }

  var bot = new Bot
  {
    Name = botDto.Name,
    Status = botDto.Status,
    CryptoPairId = cryptoPair.Id,
    TimeIntervalId = timeInterval.Id
  };

  try
  {
    await _botService.CreateAsync(bot);
  }
  catch (Exception ex)
  {
    return BadRequest(new { Error = ex.InnerException.Message });
  }

  return CreatedAtAction(nameof(GetByIdAsync), new { id = bot.Id }, _mapper.Map<BotCreateUpdateDto>(bot));
}

我有同样的问题。我只换了endpoints.MapControllers();至 endpoints.MapDefaultControllerRoute(); .第一个不指定任何路由，第二个设置默认路由。

app.UseEndpoints(endpoints =>
{
    endpoints.MapDefaultControllerRoute();
});
