.NET函数无法检索正确的数据

问题描述

我已经在我的情况控制器中创建了一个方法，以JSON格式获取情况列表。该方法称为GetSituations。

namespace Amaz.API.Controllers
{
    [ServiceFilter(typeof(LogUserActivity))]
    [Authorize]
    [Route("api/[controller]")]
    [ApiController]
    public class SituationController : ControllerBase
    {
        private readonly IVVRepository _repo;
        private readonly IMapper _mapper;
        public SituationController(IVVRepository repo,IMapper mapper)
        {
           
            _mapper = mapper;
            _repo = repo;

        }

        [HttpGet("{UserId}")]
        public async Task<IActionResult> GetSituations (int UserId)
        {
            var currentUserId = int.Parse(User.FindFirst(ClaimTypes.NameIdentifier).Value);

            var situationreturn = await _repo.GetSituations(UserId);

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

            return Ok(situationreturn);
        }

        [HttpGet("{id}")]
        public async Task<IActionResult> GetSituation (int id)
        {
            // if (id != int.Parse(User.FindFirst(ClaimTypes.NameIdentifier).Value))
            // return Unauthorized();

            var situationreturn = await _repo.GetSituation(id);

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

            return Ok(situationreturn);
        }

        [HttpPost]
        public async Task<IActionResult> PutSituation(SituationDto SituationDto)
        {
            var SituationToCreate = _mapper.Map<Situation>(SituationDto);
            _repo.Add(SituationToCreate);
            await _repo.SaveAll();

            return NoContent();
        }


        [HttpPut("{id}")]
        public async Task<IActionResult> UpdateSituation(int id,SituationDto SituationDto)
        {
            var situation = await _repo.GetSituation(id);
            _mapper.Map(SituationDto,situation);
            return NoContent();
        }

        [HttpDelete("{id}")]
        public async Task<IActionResult> DeleteSituation (int id)
        {            
              var SituationFromrepo = await _repo.GetSituation(id);
              _repo.Delete(SituationFromrepo);
              return NoContent();
        }
    }
}

在存储库中：

public async Task<IEnumerable<Situation>> GetSituations (int UserId)
{
    var messages = _context.Messages.AsQueryable();
    return (IEnumerable<Situation>)messages;
}

并在存储库的界面中：

Task<IEnumerable<Situation>> GetSituations (int UserId);

但是由于任何原因，它都无法正常工作。使用Postman测试API http://localhost:5000/api/Situation/1时，返回仅是以下情况之一：

{
    "id": 1,"description": "Limpieza","isMain": false,"userId": 1,"isApproved": true,"item1": 0,"item2": 1,"item3": 2,"item4": 3,"item5": 4,"item6": 5,"item7": 6,"item8": 7,"item9": 8,"item10": 9,"item11": 10,"item12": 11,"item13": 12,"item14": 13,"item15": 14,"item16": 15,"item17": 16,"item18": 17,"item19": 18,"item20": 19
}

但是，实际上，它应该返回存储在数据库中的所有情况。为什么它不起作用？

解决方法

不能有两个具有相同路由的HttpGet方法。当您调用该路由时，只有其中一个会被命中，而当您使用http://localhost:5000/api/Situation/1时，它现在正在命中GetSituation端点而不是GetSituations端点。您需要向其中至少一个添加特定的路由。您可以为此使用属性路由：

[HttpGet("{UserId}")]
[Route("all")]
public async Task<IActionResult> GetSituations (int UserId)

然后尝试到达以下端点：http://localhost:5000/api/Situation/all/1从GetSituations检索数据。

继续使用此端点：http://localhost:5000/api/Situation/1从GetSituation检索数据。

嗯，它仍然无法正常工作。按照我定义的控制器：

        [Route("api/[controller]/all")]
        [HttpGet]
         public async Task<IActionResult> GetSituations ()
        {
            var currentUserId = int.Parse(User.FindFirst(ClaimTypes.NameIdentifier).Value);

            var situationstoreturn = await _repo.GetSituations();

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

            return Ok(situationstoreturn);
        }

接口存储库中的函数

    Task<IEnumerable<Situation>> GetSituations ();

和存储库：

     public async Task<IEnumerable<Situation>> GetSituations ()
    {
        var Situation = _context.Situations.ToListAsync();
        return await Situation;
    }

http://localhost:5000/api/Situation/all的结果是：

{
    "errors": {
        "id": [
            "The value 'all' is not valid."
        ]
    },"type": "https://tools.ietf.org/html/rfc7231#section-6.5.1","title": "One or more validation errors occurred.","status": 400,"traceId": "|fafb39a-479332ff01211120."
}

它本来可以工作，但是仍然失败了……我不知道这个线索……

现在，这是最新技术。这里是控制器：

namespace Amaz.API.Controllers
{
    [ServiceFilter(typeof(LogUserActivity))]
    [Authorize]
    [Route("api/[controller]")]
    [ApiController]
    public class SituationController : ControllerBase
    {
        private readonly IVVRepository _repo;
        private readonly IMapper _mapper;
        public SituationController(IVVRepository repo,IMapper mapper)
        {
           
            _mapper = mapper;
            _repo = repo;

        }
        //We pick UP all the situations with GET
        [Route("all")]
        [HttpGet]
         public async Task<IActionResult> GetSituations (int UserId)
        {
            //Esto debería devolver el usuario
            var currentUserId = int.Parse(User.FindFirst(ClaimTypes.NameIdentifier).Value);

            var situationstoreturn = await _repo.GetSituations(UserId);

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

            return Ok(situationstoreturn);
        } 

        //GET only one situation
        [HttpGet("{id}")]
        public async Task<IActionResult> GetSituation (int id)
        {
            // if (id != int.Parse(User.FindFirst(ClaimTypes.NameIdentifier).Value))
            // return Unauthorized();

            var situationreturn = await _repo.GetSituation(id);

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

            return Ok(situationreturn);
        }
        //Añadimos situación POST
        [HttpPost]
        public async Task<IActionResult> PutSituation(SituationDto SituationDto)
        {
            var SituationToCreate = _mapper.Map<Situation>(SituationDto);
            _repo.Add(SituationToCreate);
            await _repo.SaveAll();

            return NoContent();
        }

        //Update Situacion PUT
        [HttpPut("{id}")]
        public async Task<IActionResult> UpdateSituation(int id,SituationDto SituationDto)
        {
            var situation = await _repo.GetSituation(id);
            _mapper.Map(SituationDto,situation);
            return NoContent();
        }
        //Delete Situation DEL
        [HttpDelete("{id}")]
        public async Task<IActionResult> DeleteSituation (int id)
        {            
              var SituationFromRepo = await _repo.GetSituation(id);
              _repo.Delete(SituationFromRepo);
              return NoContent();
        }
    }
}

存储库为：

public async Task<IEnumerable<Situation>> GetSituations(int UserId)
{
    var user = await _context.Users.FirstOrDefaultAsync(u => u.Id == UserId);
    var Situation = _context.Situations.ToListAsync();
    return await Situation;

}

不幸的是，当我给API邮递员这个呼叫时：

http://localhost:5000/api/Situation/all/

我获得：

{
    "errors": {
        "id": [
            "The value 'all' is not valid."
        ]
    },"traceId": "|6e318df2-469ed81893adc4fa."
}

因此，我认为不可能在给定UserId的情况下获取数组
