Question

我一直在研究，但是仍然找不到解决方案，

要返回所有玩家，我将传递类似以下内容： http：// localhost：7777 / api / teams / 34fe3b6f-ba23-4657-820a-6c59dd49173a / players

要返回特定团队中的特定球员，我将传递类似于以下内容的内容： http：// localhost：7777 / api / teams / 34fe3b6f-ba23-4657-820a-6c59dd49173a / players / f7de7974-9cbb-4c2c-884e-29036d6c2d76

我不断收到以下错误： System.ArgumentException：'路由参数名称'id'在路由模板中出现多次。 '

有人可以建议如何解决此问题吗？

[Route("api/Teams/{Id}/Players}")]
[ApiController]
public class PlayersController : ControllerBase
{

    [HttpGet]
    public IActionResult GetAllTeamPlayers(Guid id)
    {
        return Ok();
    }

    [HttpGet]
    public IActionResult GetTeamPlayer(Guid id, Guid id2)
    {
        return Ok();
    }
}

您应该这样定义路线参数：

[Route("api/Teams/{teamId}/}")]
[ApiController]
public class PlayersController : ControllerBase
{

    [HttpGet("players")]
    public IActionResult GetAllTeamPlayers([FromRoute] Guid teamId)
    {
        return Ok();
    }

    [HttpGet("players/{playerId}")]
    public IActionResult GetTeamPlayer([FromRoute] Guid teamId, [FromRoute] Guid playerId)
    {
        return Ok();
    }
}
