c# - 本地测试 web api 时出现 404 not found 错误

Question

这是我第一次尝试在项目中使用 WEB API，但没有成功......

当我尝试在 Fiddler 中访问我的 api 路由时，我不断收到 404 错误。

我尝试在网络上甚至这里的以下链接中查找很多内容，但组合太多，我不确定哪种方法可行。

HTTP 404 Page Not Found in Web Api hosted in IIS 7.5

如果有人可以请帮助我获得正确的设置，我将真的感激不尽。

这是我的代码: Web.config 文件:

using System.Web.Http;

namespace FuelTicketImageRetrievalSvc
{
    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 }
            );
        }
    }
}

Global.asax.cs 文件:

using FuelTicketImageRetrieval;
using System.Web.Http;
using System.Web.Mvc;
using System.Web.Optimization;
using System.Web.Routing;

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

我尝试调用的 Controller 方法。它只是一个虚拟方法，它只返回没有参数的 null。它的名称是 FuelTicketImageRetrievalController:

public string GetSpecificFuelTicket()
        {
            try
            {
                return null;
            }
            catch (Exception ex)
            {
                return null;
            }
        }

我的项目名为 FuelTicketImageRetrievalSvc。我已经通过项目中的 Web 设置验证正在使用 IIS Express 并设置为

http://localhost:11581/

url路径调用。

http://localhost:11581/FuelTicketImageRetrievalSvc/api/GetSpecificFuelTicket

Answer 1

你不需要 FuelTicketImageRetrievalSvc 在 uri 中，它应该可以简单地与 /api/... 一起工作 这就是您的路线匹配的内容，那里有 svc 名称会导致它不匹配。
