c# - HttpGet在Mvc Core 2.0中返回404

public class SurveyController : Controller
{
    public IActionResult Index()
    {
        var surveys = new List<int>{1};
        return View(Surveys);
    }

    [HttpGet("conditions")]
    public IActionResult GetConditions()
    {
        List<int> Conditions = new List<int{1};
        return View("Conditions",Conditions);
    }
}

现在的意见是

Views/Survey/Index.cshtml

Views/Survey/Conditions.cshtml

路由Survey/conditions返回404。

有人知道吗？

我的startup.cs是-

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?}");
    });
}

最佳答案

您对动作具有的属性：

[HttpGet("conditions")]

指定您希望URL为http://whatever/conditions。相反，您应该使用：

[HttpGet("/survey/conditions")]

如果您希望以更好的粒度来控制路由，则应改用Route属性。例如：

[Route("[controller]")] //Set the prefix for subsequent route attributes
public class SurveyController : Controller
{
    [Route("conditions")]
    public IActionResult GetConditions()
    {
        List<int> Conditions = new List<int{1};
        return View("Conditions",Conditions);
    }
}
