c#托管休息服务返回404

Question

我已经在 c# 中实现了我的控制器

[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;
            }

然后我尝试托管它以便可以在 jquery 上通过 AJAX 调用它，因为我的应用程序将是移动跨平台的，我必须将客户端与服务器端分开，无论如何，这是托管的主要方法：

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();
        }
    }

主机启动并正在侦听，但是当我通过 javascript 调用 URL 时，我收到 404 错误消息。

HTTP 状态码 404。

这是javascript代码：

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

我还使用了 chrome 的 CORS 启用程序，如何检查我的路径是否有效？ 我应该改变托管服务的方式吗？

这是我的 app.config 如果它可以帮助：

您如何托管您的服务？

当服务运行时，您如何确保端口实际上是 8080？ - 它可能会给出 404 错误，因为它是错误的端口

例如，如果您的服务仅存在于 Visual Studio 中，并且您按 F5 开始调试，它会自动在您的浏览器中为您打开一个新窗口，并且您会在右下角任务栏区域看到“IIS Express”图标：端口可能会有所不同。
