我有一个ASP.NET Core空白项目,它非常适合通过https://localhost/filename提供静态文件。现在,我想向其中添加MVC函数。但是引用https://docs.microsoft.com/en-us/aspnet/core/tutorials/first-mvc-app/adding-controller?view=aspnetcore-2.2&tabs=visual-studio,添加“ Controllers”文件夹后,添加一个控制器类:

public class HelloWorldController : Controller
{
    // 
    // GET: /HelloWorld/Welcome/ 

    public string Welcome()
    {
        return "This is the Welcome action method...";
    }
}

StartUp.cs就像:

    public void ConfigureServices(IServiceCollection services)
    {
        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.UseMvc();
        app.UseStaticFiles();
    }

Builder就像:

return WebHost.CreateDefaultBuilder(args)
            .UseStartup<Startup>();

毕竟,我仍然无法访问“ https://localhost/HelloWorld/Welcome/”。

我省略了什么?

您没有指定默认路由,也没有为此指定任何形式的路由。最快的解决方法是将app.UseMvc()更改为app.UseMvcWithDefaultRoute()。或者,您可以添加属性路由:

[Route("[controller]")]
public class HelloWorldController : Controller
{

    [HttpGet("Welcome")]
    public string Welcome()
    {
        return "This is the Welcome action method...";
    }
}
