我正在學習Angular 2並試圖讓它在ASP MVC設置上運行。我遵循這個非常優秀的指南:https://www.codeproject.com/Articles/1181888/Angular-in-ASP-NET-MVC-Web-API-PartASP MVC Web API端點返回404
我修改它非常輕微。原本應該處理通過API端點api/userapi
從數據庫中獲取的名稱列表。我改變了它,以便它成爲來自端點api/postapi
的帖子列表(如博客或其他內容)。該項目的角度部分目前工作。它的ASP.NET部分工作不正常。
查看原始項目的配置(我從該鏈接下載並在Visual Studio 2017中測試得很好)並將其與我的實驗進行比較,對於我的生活,我無法找到可能錯誤配置的位置它。
這裏有什麼問題?這裏是我的Web API部分代碼:
Global.asax.cs
using System.Web.Http;
using System.Web.Mvc;
using System.Web.Optimization;
using System.Web.Routing;
namespace WebAPI
{
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);
}
}
}
RouteConfig.cs
using System.Web.Mvc;
using System.Web.Routing;
namespace WebAPI
{
public class RouteConfig
{
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapRoute(
name: "Default",
url: "{*anything}", // I am suspicious of this line but changing it doesn't fix it
defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
);
}
}
WebApiConfig.cs
using System.Net.Http.Headers;
using System.Web.Http;
namespace WebAPI
{
public static class WebApiConfig
{
public static void Register(HttpConfiguration config)
{
// Web API configuration and services
// Output as JSON instead of XML
config.Formatters.JsonFormatter.SupportedMediaTypes
.Add(new MediaTypeHeaderValue("application/octet-stream"));
// Web API routes
config.MapHttpAttributeRoutes();
config.Routes.MapHttpRoute(
name: "DefaultApi",
routeTemplate: "api/{controller}/{id}",
defaults: new { id = RouteParameter.Optional }
);
}
}
}
PostsAPIController.cs
using WebAPI.Models;
using System.Data.Entity;
using System.Linq;
using System.Net.Http;
using System.Web.Http;
namespace WebAPI.Controllers
{
[RoutePrefix("api/postapi")] //this did not help either
public class PostsAPIController : BaseAPIController
{
public HttpResponseMessage Get()
{
return ToJson(_db.TWebSitePostsSet.AsEnumerable());
}
public HttpResponseMessage Post([FromBody]TWebSitePosts value)
{
_db.TWebSitePostsSet.Add(value);
return ToJson(_db.SaveChanges());
}
public HttpResponseMessage Put(int id, [FromBody]TWebSitePosts value)
{
_db.Entry(value).State = EntityState.Modified;
return ToJson(_db.SaveChanges());
}
public HttpResponseMessage Delete(int id)
{
_db.TWebSitePostsSet.Remove(_db.TWebSitePostsSet.FirstOrDefault(x => x.PostId == id));
return ToJson(_db.SaveChanges());
}
}
}
你必須把這裏的角代碼API調用端點提供正確的答案.... –
你錯過了HTTPS動詞來識別REST調用> [HTTPGET] [HttpPost] ..... –
我想,但這是很多代碼,並且它與爲什麼api url本身返回404如果直接進入它無關。 –
