C# 无法使用GET访问API终结点

我正在努力构建一个API来处理.NETCore中的身份信息，但每次我尝试调用时，都会得到一个404

当我四处寻找答案时，似乎什么都不清楚，因为发布的代码似乎非常少。以下是所有我认为相关的东西

控制员：

using Common.Extensions;
using Identity.Database.Contexts.Models;
using Identity.WebApi.Models;
using Identity.WebApi.Models.Tokens;
using Identity.WebApi.Services.Access;
using Identity.WebApi.Services.Accounts;
using Identity.WebApi.Services.Tokens;
using Microsoft.AspNetCore.Authorization;
using Microsoft.AspNetCore.Identity;
using Microsoft.IdentityModel.Tokens;
using System;
using System.Collections.Generic;
using System.Security.Claims;
using System.Threading.Tasks;

using Controller = Microsoft.AspNetCore.Mvc.Controller;
using Get = Microsoft.AspNetCore.Mvc.HttpGetAttribute;
using Post = Microsoft.AspNetCore.Mvc.HttpPostAttribute;
using Route = Microsoft.AspNetCore.Mvc.RouteAttribute;

namespace Identity.WebApi.Controllers
{
    [Route("api/[controller]")]
    public class IdentityController : Controller
    {
        private readonly IApplicationUserService _userService;
        private readonly IAccessService _accessService;
        private readonly ITokenService _tokenService;
        private readonly SignInManager<ApplicationUser> _signInManager;

        public IdentityController(IApplicationUserService userService, IAccessService accessService, ITokenService tokenService, SignInManager<ApplicationUser> signInManager)
        {
            _userService = userService;
            _accessService = accessService;
            _tokenService = tokenService;
            _signInManager = signInManager;
        }

        [Get]
        [AllowAnonymous]
        public string Index()
        {
            return new Dictionary<string,string>
            {
                { "status", "live" }
            }.Serialize();
        }

        [Post]
        [Route("create")]
        [AllowAnonymous]
        public Task<ISet<IdentityResult>> Create(string user)
        {
            var decodedUser = DecodeUser(user);

            var applicationUser = new ApplicationUser(new User
            {
                Id = Guid.NewGuid(),
                Name = decodedUser.Username,
                LastActive = DateTime.UtcNow
            });

            return _userService.Add(applicationUser, decodedUser.Password);
        }       

        private (string Username, string Password) DecodeUser(string encodedUser)
        {
            var decodedUser = encodedUser.DecodeFrom64().Split(':');
            return (Username: decodedUser[0], Password: decodedUser[1]);
        }

        private async Task<bool> CheckPasswordAsync(ApplicationUser user, string password)
            => await _signInManager.UserManager.CheckPasswordAsync(user, password);
    }
}

如果使用属性路由，则没有

api/identity/index

，因为示例中带有路由前缀的

[HttpGet]

或

Get

与

[Get] //<-- Matches GET api/identity
[AllowAnonymous]
public IActionResult Index() {
    var result = new Dictionary<string,string>
        {
            { "status", "live" }
        }.Serialize();
    return Ok(result);
}

---

参考控制器顶部的以下内容：

[Route("api/[controller]")]
public class IdentityController : Controller

这意味着，如果您的路由仅从

api/

开始，那么它将与控制器匹配。此外，索引操作上没有任何额外的路由属性，因此它只查找

api/identity

。但是，您的启动设置与该部分不匹配，并且由于您没有任何其他与之匹配的路由，因此您将获得404

由于这个原因，

app.UseMvc

中的默认路由将不起作用

---

简单修复：在您的启动设置中将

launchUrl

更改为

api/identity

。。。然后跟随@Nkosi的

你能把返回404的路线包括进去吗？哦。。。谢谢@Nkosi，我错过了。我想你是对的-启动设置只需要更新到

api/identity

是的，这一次让我很失望。现在，我通过控制器看到了我预期的依赖项注入错误（第一次在.NETCore中这样做）。谢谢

[Get] //<-- Matches GET api/identity
[AllowAnonymous]
public IActionResult Index() {
    var result = new Dictionary<string,string>
        {
            { "status", "live" }
        }.Serialize();
    return Ok(result);
}

[Post("create")]  //<-- Matches POST api/identity/create
[AllowAnonymous]
public async Task<IActionResult> Create(string user) {
    var decodedUser = DecodeUser(user);

    var applicationUser = new ApplicationUser(new User
    {
        Id = Guid.NewGuid(),
        Name = decodedUser.Username,
        LastActive = DateTime.UtcNow
    });

    ISet<IdentityResult> result = await _userService.Add(applicationUser, decodedUser.Password);
    return Ok(result);
}

[Route("api/[controller]")]
public class IdentityController : Controller
