[英]Does .NET core 2.1 web API support convention based routing?
I am new to Web API and .net core, and I have a task to develop an API. 我是Web API和.net核心的新手,我有一个开发API的任务。
So I have created a default web API (framework: .NET Core 2.1) and tried adding the route map and i am getting an error. 因此,我创建了默认的Web API(框架:.NET Core 2.1),并尝试添加路线图,但出现错误。
guys can someone help me with routing. 伙计们可以帮助我进行路由。
Note: Cant use attribute based routing need to handle routes based on a convention like in MVC 注意:基于Cant Use属性的路由需要基于MVC之类的约定来处理路由
My startup program: 我的启动程序:
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.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Version_2_1);
}
// 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();
}
else
{
app.UseHsts();
}
//app.UseHttpsRedirection();
app.UseMvc(routes =>
{
routes.MapRoute(
name: "default",
template: "{controller}/{action}/{id?}",
defaults: new { controller = "Values", action = "dummyaction" });
});
}
}
And this is the error i am getting: 这是我得到的错误:
InvalidOperationException: Action 'myproject.Controllers.ValuesController.dummyaction (myproject)' does not have an attribute route.
InvalidOperationException:操作'myproject.Controllers.ValuesController.dummyaction(myproject)'没有属性路由。 Action methods on controllers annotated with ApiControllerAttribute must be attribute routed.
必须对使用ApiControllerAttribute注释的控制器上的操作方法进行属性路由。
You can do with this sample 您可以使用此样本
namespace TodoApi.Controllers
{
[Route("api/[controller]")]
[ApiController]
public class TodoController : Controller
{
[HttpGet("{id}")]
public async Task<ActionResult<TodoItem>> GetTodoItem(long id)
{
//do here
}
}
}
How I got it working 我如何运作
even after using map route I was still getting the error which talks about attribute-based routing 即使在使用地图路线后,我仍然会遇到有关基于属性的路线的错误
app.UseMvc(routes =>
{
routes.MapRoute(
name: "default",
template: "{controller}/{action}/{id?}",
defaults: new { controller = "Values", action = "dummyaction" });
});
So in the error can you see this line "Action methods on controllers annotated with ApiControllerAttribute must be attribute routed."
因此,在错误中您可以看到以下行:“必须对使用ApiControllerAttribute注释的控制器上的操作方法进行属性路由。”
Now in my controller, I was using this particular annotation/attribute "[ApiController]" by removing that I was able to perform convention-based routing. 现在,在我的控制器中,我删除了能够执行基于约定的路由,从而使用了此特定注释/属性“ [ApiController]”。
also, I have updated the route as below 另外,我还更新了如下路线
app.UseMvc(routes =>
{
routes.MapRoute(
name: "api",
template: "api/{controller=Values}/{action=gogogo}/{id?}");
});
