调用 ASP.Net 核心时 404 API

Question

我有一个带有 Web API 控制器的 ASP.Net 核心 MVC 应用程序，我相信我提供了正确的路由和所有内容，但在调用任何 API 邮递员中的控制器

控制器的外观如下：

[Route("api/[controller]")]
    [ApiController]
    public class PetsController : Controller
    {
        private readonly IPetService _petService;

        public PetsController(IPetService _petService)
        {
            this._petService = _petService;
        }

        [HttpPost("Activation")]
        public async Task<IActionResult> Activation(Guid id)
        {
            var serviceResult = await _petService.DeletePet(id);
            return Ok(serviceResult);
        }

        [HttpGet("GetPet/{id}")]
        public async Task<IActionResult> GetPet(Guid id)
        {
            var serviceResult = await _petService.GetPetDetails(id);
            return Ok(serviceResult);
        }

        [HttpGet("GetPets/{pageSize}/{pageIndex}/{keyWord}")]
        public async Task<IActionResult> GetPets(int pageSize, int pageIndex, string keyWord)
        {
            var serviceResult = await _petService.GetPets(pageSize, pageIndex, keyWord);
            return Ok(serviceResult);
        }

        [HttpPost("SavePet")]
        public async Task<IActionResult> SavePet(PetDTO pet)
        {
            var serviceResult = (Object)null;

            if (!pet.Id.HasValue)
                serviceResult = await _petService.CreatePet(pet);
            else
                serviceResult = await _petService.EditPet(pet);

            return Ok(serviceResult);
        }

        [HttpGet("GetPetDues/{id}")]
        public async Task<IActionResult> GetPetDues(Guid id)
        {
            var serviceResult = await _petService.GetPetDues(id);
            return Ok(serviceResult);
        }

        [HttpGet("GetPetAppointments/{id}")]
        public async Task<IActionResult> GetPetAppointments(Guid id)
        {
            var serviceResult = await _petService.GetPetAppointments(id);
            return Ok(serviceResult);
        }

        [HttpGet("GetPetDiseases/{petId}")]
        public async Task<IActionResult> GetPetDiseases(Guid petId)
        {
            var serviceResult = await _petService.GetPetDiseases(petId);
            return Ok(serviceResult);
        }
    }

启动设置：

"iisSettings": {
    "windowsAuthentication": false, 
    "anonymousAuthentication": true, 
    "iisExpress": {
      "applicationUrl": "http://localhost:50521",
      "sslPort": 44310
    }

这是我如何在 Postman 中调用 API 的示例： http://localhost:50521/api/pets/GetPets/10/0/

我相信我应该得到 200 OK 但我仍然收到 404 错误！我该如何解决这个问题？

路线模板使用不当

[HttpGet("GetPets/{pageSize}/{pageIndex}/{keyWord?}")]
public async Task<IActionResult> GetPets(int pageSize, int pageIndex, string keyWord = null)
{
    var serviceResult = await _petService.GetPets(pageSize, pageIndex, keyWord);
    return Ok(serviceResult);
}

原来使用的路由缺少模板参数。

事实上，所有显示的路线都缺少路线模板中的参数。

Route template reference

Tokens within curly braces ({ ... }) define route parameters that are bound if the route is matched. You can define more than one route parameter in a route segment, but they must be separated by a literal value. For example, {controller=Home}{action=Index} isn't a valid route, since there's no literal value between {controller} and {action}. These route parameters must have a name and may have additional attributes specified.

Literal text other than route parameters (for example, {id}) and the path separator / must match the text in the URL. Text matching is case-insensitive and based on the decoded representation of the URLs path. To match a literal route parameter delimiter ({ or }), escape the delimiter by repeating the character ({{ or }}).
