邮递员请求不返回任何内容

Question

我创建了小型 Rest API 应用程序并尝试使用 Postman 对其进行测试，但一无所获。

这是以下代码：

-动物

namespace VeterinaryClinicShelter.Models;

public class Animal
{
    public int Id { get; set; }
    public string Name { get; set; }
    public string Category { get; set; }
    public double Weight { get; set; }
    public string FurColor { get; set; }
}

-动物控制器

using Microsoft.AspNetCore.Mvc;
using VeterinaryClinicShelter.Models;

namespace VeterinaryClinicShelter.Controllers;

[ApiController]
[Route("[controller]")]
public class AnimalController : ControllerBase
{
    private static readonly List<Animal> Animals =
    [
        new Animal { Id = 1, Name = "Buddy", Category = "Dog", Weight = 15.2, FurColor = "Brown" },
        new Animal { Id = 2, Name = "Whiskers", Category = "Cat", Weight = 7.5, FurColor = "White" },
        new Animal { Id = 3, Name = "Fluffy", Category = "Cat", Weight = 6.8, FurColor = "Gray" },
        new Animal { Id = 4, Name = "Max", Category = "Dog", Weight = 20.5, FurColor = "Black" },
        new Animal { Id = 5, Name = "Snowball", Category = "Rabbit", Weight = 3.2, FurColor = "White" }
    ];

    [HttpGet]
    public ActionResult<List<Animal>> GetAnimals()
    {
        return Animals;
    }

    [HttpGet("{id}")]
    public ActionResult<Animal> GetAnimalById(int id)
    {
        var animal = Animals.FirstOrDefault(a => a.Id == id);

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

        return animal;
    }

    [HttpPost]
    public ActionResult<Animal> AddAnimal(Animal animal)
    {
        if (Animals.Any(a => a.Id == animal.Id))
        {
            return Conflict("Animal with such ID already exists");
        }

        Animals.Add(animal);

        return CreatedAtAction(nameof(GetAnimalById), new { id = animal.Id }, animal);
    }

    [HttpPut("{id:int}")]
    public ActionResult<Animal> EditAnimal(int id, Animal newAnimal)
    {
        var index = Animals.FindIndex(animal => animal.Id == id);

        if (index == -1) return NotFound();

        Animals[index].Name = newAnimal.Name;
        Animals[index].Category = newAnimal.Category;
        Animals[index].Weight = newAnimal.Weight;
        Animals[index].FurColor = newAnimal.FurColor;
        return NoContent();
    }

    [HttpDelete("{id:int}")]
    public ActionResult<Animal> DeleteAnimal(int id)
    {
        var deleteAnimal = Animals.FirstOrDefault(animal => animal.Id == id);

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

        Animals.Remove(deleteAnimal);
        return NoContent();
    }
}

邮差GET请求：

http://localhost:5039/Animal/2

我确定我使用的是正确的端口。

如果该信息有帮助： IDE：Rider，模板：ASP.NET Core Web 应用程序模板，类型：Blazor Web App，框架：net8.0

我询问了这个问题，没有给我任何有用的信息。

Answer 1

你尝试过吗

return Ok(animal)

？

或者您的请求端点可能应以

"https:\\"

开头，而不是

"http:\\"
