c# - HttpGet 在 Mvc 核心 2.0 中返回 404

Question

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);
    }
}

现在浏览量低于

Views/Sur​​vey/Index.cshtml

Views/Sur​​vey/Conditions.cshtml

路线 Survey/conditions 正在返回 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?}");
    });   
}

Answer 1

你对 Action 的属性:

[HttpGet("conditions")]

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

[HttpGet("/survey/conditions")]

如果您希望以更好的粒度控制路由，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);
    }
}
