.NET Core 和 MVC 项目，api 控制器路由不起作用

Question

在使用 VS 2017 创建的项目（包括 MVC 和 Web API）中，当我添加一个新控制器时，默认路由调用 Index() 函数到那个新的 API 控制器但是浏览到任何其他方法都失败。

API代码

namespace TestApi.Controllers
{
[Produces("application/json")]
[Route("api/TestAPI")]
public class TestAPIController : Controller
{
    public string Index()
    {
        //if (!_signInManager.IsSignedIn(User))
        //return RedirectToAction("Login", "Account");

        return "View()";
    }

    //[Route("GetTestData")]
    [HttpGet]
    private string GetTestData()
    {
        return "Data";
    }
}
}

Startup class 中的代码如下：

 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.AddSingleton<IActionContextAccessor, ActionContextAccessor>();
        services.AddScoped<IUrlHelper>(factory =>
        {
            var actionContext = factory.GetService<IActionContextAccessor>()
                                       .ActionContext;
            return new UrlHelper(actionContext);
        });

        services.AddDbContext<ApplicationDbContext>(options =>
            options.UseSqlServer(Configuration.GetConnectionString("DefaultConnection")));

        services.AddIdentity<ApplicationUser, IdentityRole>()
            .AddEntityFrameworkStores<ApplicationDbContext>()
            .AddDefaultTokenProviders();

        // Add application services.
        services.AddTransient<IEmailSender, EmailSender>();

        services.AddMvc();
    }

    // This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
    public void Configure(IApplicationBuilder app, IHostingEnvironment env)
    {
        if (env.IsDevelopment())
        {
            app.UseDeveloperExceptionPage();
            app.UseBrowserLink();
            app.UseDatabaseErrorPage();
        }
        else
        {
            app.UseExceptionHandler("/Home/Error");
        }

        app.UseStaticFiles();

        app.UseAuthentication();

        app.UseMvc(routes =>
        {
            routes.MapRoute(
                name: "default",
                template: "{controller=Home}/{action=Index}/{id?}");
        });


    }
}

因此浏览到“https://localhost:44314/api/TestAPI" works but when i try to browse to "https://localhost:44314/api/TestAPI/GetTestData”时出现找不到页面错误。

感谢您的帮助。

Answer 1

可能是您的 GetTestData 操作方法是私有的。尝试制作 public.

Answer 2

使用这个：

[Route("api/[controller]/[action]")]
public class TestAPIController : Controller
{

}

然后您可以浏览所有操作。

但可能想要更改动作名称，因此您应该这样编码：

[Route("api/[controller]/[action]")]
public class TestAPIController : Controller
{
    [ActionName("start-here")]
    public JsonResult Start()
    {
        return Json();
    }
}

并且您可以使用如下参数为操作指定特定路径：

[Route("api/[controller]/[action]")]
public class TestAPIController : Controller
{
    [ActionName("start-here")]
    public JsonResult Start()
    {
        return Json();
    }

    [route("api/[controller]/nearby-businesses/{locationType}")]
    public JsonResult nearby_businesses(string locationType)
    {
        return Json();
    }
}
