.NET Core 3.1 MVC with Web API 路由不工作

Question

我之前在 .NET Framework 工作过，现在开始使用 .NET Core。

我正在构建一个既是 MVC 又是 Web 的应用程序 API，但我的某些路由无法正常工作。

这是我的控制器代码：

    [Route("api/[controller]")]
    [ApiController]
    public class ClientController : ControllerBase
    {
        private readonly ApplicationDbContext db;
        public ClientController(ApplicationDbContext context)
        {
            db = context;
        }

        [HttpGet]
        public ActionResult Get()
        {
            return Ok("get works");
        }

        [HttpGet]
        public ActionResult Test()
        {
            return Ok("test not working");
        }

        [HttpGet]
        [Route("api/client/input")]
        public ActionResult input(int id)
        {
            return Ok(string.Format("Your id: {0}", id));
        }
    }

这是我的 startup.cs 代码：

    public class Startup
    {
        public Startup(IConfiguration configuration)
        {
            Configuration = configuration;
        }

        public IConfiguration Configuration { get; }

        // This method gets called by the runtime. Use this method to add services to the container.
        public void ConfigureServices(IServiceCollection services)
        {
            services.AddDbContext<ApplicationDbContext>(opts => opts.UseSqlServer(Configuration.GetConnectionString("sqlConnection")));
            services.AddMvc();
        }

        // This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
        public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
        {
            if (env.IsDevelopment())
            {
                app.UseDeveloperExceptionPage();
            }
            else
            {
                app.UseExceptionHandler("/Home/Error");
                // The default HSTS value is 30 days. You may want to change this for production scenarios, see https://aka.ms/aspnetcore-hsts.
                app.UseHsts();
            }

            app.UseHttpsRedirection();
            app.UseStaticFiles();

            app.UseRouting();

            app.UseAuthorization();
            app.UseEndpoints(endpoints =>
            {
                endpoints.MapControllerRoute(
                name: "default",
                pattern: "{controller=Home}/{action=Index}/{id?}");
            });
        }
    }

https://localhost:5001/api/client 有效
https://localhost:5001/api/client/test 404错误
https://localhost:5001/api/client/2 404 错误
https://localhost:5001/api/client?id=2 404 错误

我已经尝试将特定路线添加到我的个人操作中，但没有效果。

提前致谢。

你无法获得任何为控制器制作这样的路由属性

  [Route("api/[controller]")]
    [ApiController]
    public class ClientController : ControllerBase

您可以使用 [ApiController] 一起从控制器中删除任何属性路由，或者像这样

   [Route("api/[controller]/[action]")]
    [ApiController]
    public class ClientController : ControllerBase

在这种情况下，您可以使用此变体

        [HttpGet]
        public ActionResult Get() //api/client/get
        //or
         [HttpGet("GetAll")]
        public ActionResult Get() //api/client/getall

        [HttpGet]
        public ActionResult Test() //api/client/test
        {
            return Ok("test not working");
        }

并修复输入

        [HttpGet]
        [Route("~/api/client/input/{id}")] //api/client/input/4
        public ActionResult input(int id)

不过是一样的

  [HttpGet]
  public ActionResult input(int id)
