.Net Core API：没有路由与提供的值匹配

Question

我已经这样做了好几个小时了。我在这里做错了什么？

基础控制器路线

[Route("api/v{v:apiVersion}/[controller]")]
[ApiController]
[Authorize]
public class BaseControllerV2 : ControllerBase
{
}

控制器路线

public class OrdersController : BaseControllerV2
{

private readonly IOrderService _iOrderService;

public OrdersController(IOrderService iOrderService)
{
    _iOrderService = iOrderService;
}

  

  /// <summary>
    /// Retrieve order details
    /// </summary>
    [HttpGet("{orderNo:int}", Name = nameof(GetOrderByOrderNo))]
    [ProducesResponseType(StatusCodes.Status200OK)]
    [ProducesResponseType(StatusCodes.Status400BadRequest)]
    [ProducesResponseType(StatusCodes.Status404NotFound)]
    [ProducesResponseType(StatusCodes.Status500InternalServerError)]
    public async Task<ActionResult<Business.Models.V2.Order>> GetOrderByOrderNo([FromRoute]int orderNo, [BindRequired, FromQuery]int agencyNo, CancellationToken cancellationToken)
    {
        var result = await _iOrderService.GetOrderByOrderNo(orderNo, agencyNo, cancellationToken);

        if (result == null) return NotFound();

        return Ok(result);
    }

    /// <summary>
    /// Create quote
    /// </summary>
    [HttpPost(Name = nameof(CreateQuote))]
    [ProducesResponseType(StatusCodes.Status201Created)]
    [ProducesResponseType(StatusCodes.Status400BadRequest)]
    [ProducesResponseType(StatusCodes.Status500InternalServerError)]
    public async Task<ActionResult<Business.Models.V2.Order>> CreateQuote([FromBody]Business.Models.V2.Order order, CancellationToken cancellationToken)
    {
        var result = await _iOrderService.CreateQuote(order, cancellationToken);

        return CreatedAtAction(nameof(GetOrderByOrderNo), new { orderNo = result.OrderNo, agencyNo = result.AgencyNo, cancellationToken}, result);
    }

}

我已经尝试了其他相关问题的解决方案，但CreatedAtAction仍然找不到端点。

Answer 1

看起来你的

GetOrderByOrderNo

只接受1个参数

HttpGet("{orderNo:int}"

，但你试图传递3个，将其他2个参数添加到HttpGet

Answer 2

控制器路径中缺少一个参数 -

{v:apiVersion}

，请尝试以下操作：

    public async Task<ActionResult<Business.Models.V2.Order>> CreateQuote([FromRoute] ApiVersion version, [FromBody]Business.Models.V2.Order order, CancellationToken cancellationToken)
    {
        var result = await _iOrderService.CreateQuote(order, cancellationToken);

        return CreatedAtAction(nameof(GetOrderByOrderNo), new { v = version.ToString(), orderNo = result.OrderNo, agencyNo = result.AgencyNo, cancellationToken}, result);
    }
