My JQuery / javascript

$.ajax({ 
 
    url: "/api/ComicApi/" + 1, 
    //data: { name: productName }, 
    type: "GET", 
    dataType: "jsonp", 
    error: function (request, status, error) { 
        alert('error'); 
    }, 
    success: function (data) { 
        alert('success'); 
    } 
}); 

Global.asax

protected void Application_Start() 
{ 
    AreaRegistration.RegisterAllAreas(); 
    FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters); 
    RouteConfig.RegisterRoutes(RouteTable.Routes); 
    BundleConfig.RegisterBundles(BundleTable.Bundles); 
    GlobalConfiguration.Configure(WebApiConfig.Register);//added this 
} 

WebApi.Config

class WebApiConfig 
{ 
    public static void Register(HttpConfiguration configuration) 
    { 
        configuration.Routes.MapHttpRoute("API Default", "api/{controller}/{id}", 
            new { id = RouteParameter.Optional }); 
    } 
} 

ComicApiController.cs

using System; 
using System.Collections.Generic; 
using System.Linq; 
using System.Net; 
using System.Net.Http; 
using System.Web.Http; 
 
namespace ComicNet.WebApi 
{ 
    public class ComicApiController : ApiController 
    { 
        // GET api/<controller> 
        public IEnumerable<string> Get() 
        { 
            return new string[] { "value1", "value2" }; 
        } 
 
        // GET api/<controller>/5 
        public string Get(int id) 
        { 
            return "value"; 
        } 
 
        // POST api/<controller> 
        public void Post([FromBody]string value) 
        { 
        } 
 
        // PUT api/<controller>/5 
        public void Put(int id, [FromBody]string value) 
        { 
        } 
 
        // DELETE api/<controller>/5 
        public void Delete(int id) 
        { 
        } 
    } 
} 

请您参考如下方法:

Web API路由需要在MVC路由之前注册

protected void Application_Start() { 
    AreaRegistration.RegisterAllAreas(); 
    GlobalConfiguration.Configure(WebApiConfig.Register);//moved higher up 
    FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters); 
    RouteConfig.RegisterRoutes(RouteTable.Routes); 
    BundleConfig.RegisterBundles(BundleTable.Bundles); 
}
