WebApi 2.0-未找到与请求URI匹配的HTTP资源

postman asp.net-web-api2 asp.net-web-api .net

TheBoubou codingbadger · 技术社区 · 6 年前

使用下面的代码,我命中了构造函数,但从未命中操作。URL为 http://localhost:64704/api/mytest/mymethod 。当我尝试像这样更改路由时,出现了相同的问题:

config.Routes.MapHttpRoute(
            name: "DefaultApi",
            routeTemplate: "api/{controller}/{action}"
        );

[Route("api/[controller]")]
public class MyTestController : ApiController
{
    readonly IMyFacade myFacade;
    public MyTestController(IMyFacade myFacade) => this.myFacade = myFacade;

    [HttpPost]
    [Route("mymethod")]
    public IHttpActionResult MyMethodName([FromBody]MyModel model)
    {
        //some code here

        return Ok();
    }
}

public static void Register(HttpConfiguration config)
{
    // Web API configuration and services

    // Web API routes
    config.MapHttpAttributeRoutes();

    config.Routes.MapHttpRoute(
        name: "DefaultApi",
        routeTemplate: "api/{controller}/{id}",
        defaults: new { id = RouteParameter.Optional }
    );
}

更新1

public class WebApiApplication : HttpApplication
{
    protected void Application_Start()
    {
        GlobalConfiguration.Configure(WebApiConfig.Register);
        UnityConfig.RegisterComponents();
    }
}

更新2

        public static void RegisterComponents()
    {
        var container = new UnityContainer();

        // register all your components with the container here
        // it is NOT necessary to register your controllers

        // e.g. container.RegisterType<ITestService, TestService>();

        /* ...... */

        GlobalConfiguration.Configuration.DependencyResolver = new UnityDependencyResolver(container);
    }

更新3 { “Field1”:“1”, “Field2”:“某个键”, “Field3”:“当然有名字” }

出现此问题是因为您希望控制器的路由属性ontop与方法的路由属性ontop合并。中的情况并非如此。网 WebApi 2.0 ,(添加到.net core mvc中)

相反,您应该在控制器上使用RoutePrefix属性,使控制器路由与方法路由合并

[RoutePrefix("api/[controller]")]
public class MyTestController : ApiController
{
    readonly IMyFacade myFacade;
    public MyTestController(IMyFacade myFacade) => this.myFacade = myFacade;

    [HttpPost]
    [Route("mymethod")]
    public IHttpActionResult MyMethodName([FromBody]MyModel model)
    {
        //some code here

        return Ok();
    }
}

WebApiConfig

public static class WebApiConfig
{
    public static void Register(HttpConfiguration config)
    {
        // Web API configuration and services

        // Web API routes
        config.MapHttpAttributeRoutes();

        config.Routes.MapHttpRoute(
            name: "DefaultApi",
            routeTemplate: "api/{controller}/{id}",
            defaults: new { id = RouteParameter.Optional }
        );
    }
}

 public class WebApiApplication : System.Web.HttpApplication
 {
     protected void Application_Start()
     {
         AreaRegistration.RegisterAllAreas();
         GlobalConfiguration.Configure(WebApiConfig.Register);
         FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
         RouteConfig.RegisterRoutes(RouteTable.Routes);
         BundleConfig.RegisterBundles(BundleTable.Bundles);
     }
 }

控制器

public class MyTestController : ApiController
{      
    [HttpPost]
    [Route("mymethod")]
    public IHttpActionResult MyMethodName([FromBody]MyModel model)
    {
        return Ok();
    }
}

调试时

发送PostRequest

Advait Baxi 6 年前

在控制器中,需要指定 RoutePrefix 属性而不是路线如下代码所示

// Specify 'RoutePrefix' attribute instead of 'Route'
[RoutePrefix("api/[controller]")]
public class MyTestController : BaseController
{
    [HttpPost]
    [Route("mymethod")]
    public HttpResponseMessage MyMethodName([FromBody]MyModel model)
    {
        return Request.CreateResponse(System.Net.HttpStatusCode.OK);
    }
}

然后再试一次。

您正在使用HttpPost谓词,请确保在发送请求时使用HttpPost方法。
