c#托管休息服務返回404

Question

我已經在 c# 中實現了我的控制器

[ServiceContract(Name = "UserController")]
public interface ApiController
{
    Task<HttpResponseMessage> SignUp(LoginModel model);

    Task<HttpResponseMessage> Login(LoginModel model);


}

namespace Nerder_Backend.Controllers
{
    [RoutePrefix("api/user")]
    public class UserController : ApiController
    {
        private readonly IBucket _bucket = ClusterHelper.GetBucket(ConfigurationManager.AppSettings.Get("CouchbaseUserBucket"));
        private readonly string _secretKey = ConfigurationManager.AppSettings["JWTTokenSecret"];

        [Route("signup")]
        [HttpPost]
        public async Task<HttpResponseMessage> SignUp(LoginModel model)
        {
            if (model == null || !model.IsValid())
            {
                HttpResponseMessage response = new HttpResponseMessage(HttpStatusCode.BadRequest)
                {
                    Content = new StringContent("Invalid email and/or password")
                };
                return response;
            }

然后我嘗試托管它以便可以在 jquery 上通過 AJAX 調用它，因為我的應用程序將是移動跨平台的，我必須將客戶端與服務器端分開，無論如何，這是托管的主要方法：

static void Main(string[] args)
        {


            var baseAddress = "http://localhost:8080";
            var config = new HttpSelfHostConfiguration(baseAddress);
            CouchbaseConfig.Register();
            GlobalConfiguration.Configure(WebApiConfig.Register);
            config.MapHttpAttributeRoutes();//map attribute routes
                                            // Create the server
            using (var server = new HttpSelfHostServer(config))
            {
            server.OpenAsync().Wait();
            Console.WriteLine("The service is ready at {0}", baseAddress);
            Console.WriteLine("Press <Enter> to stop the service.");
            Console.ReadLine();
        }
    }

主機啟動並正在偵聽，但是當我通過 javascript 調用 URL 時，我收到 404 錯誤消息。

HTTP 狀態碼 404。

這是javascript代碼：

 $.ajax({
            type: 'post',
            url: 'http://localhost:8080/api/user/signup',

我還使用了 chrome 的 CORS 啟用程序，如何檢查我的路徑是否有效？ 我應該改變托管服務的方式嗎？

這是我的 app.config 如果它可以幫助：

Answer 1

您如何托管您的服務？

當服務運行時，您如何確保端口實際上是 8080？ - 它可能會給出 404 錯誤，因為它是錯誤的端口

例如，如果您的服務僅存在於 Visual Studio 中，並且您按 F5 開始調試，它會自動在您的瀏覽器中為您打開一個新窗口，並且您會在右下角任務欄區域看到“IIS Express”圖標：端口可能會有所不同。
