这是我第一次尝试在项目中使用WEB API而且没有取得任何成功......
当我尝试在Fiddler中达到api路线时,我一直收到404错误。
我尝试在网络上看了很多,甚至在这里通过以下链接,但是有很多组合,我不知道什么会起作用。
HTTP 404 Page Not Found in Web Api hosted in IIS 7.5
如果有人可以请帮我解决这个问题,我会 真的 对此表示赞赏。
这是我的代码: Web.config文件:

WebApiConfig.cs文件:

using System.Linq;
using System.Web.Http;
namespace FuelTicketImageRetrievalSvc
{
public static class WebApiConfig
{
public static void Register(HttpConfiguration config)

// Web API routes
config.MapHttpAttributeRoutes();
config.Routes.MapHttpRoute(
name: "DefaultApi",
routeTemplate: "api/{controller}/{id}",

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);
}
}
}
我试图呼叫的控制器方法。它只是一个虚拟方法,只返回null而没有参数。它的名字是FuelTicketImageRetrievalController:
public string GetSpecificFuelTicket()
{
try
{
return null;
}
catch (Exception ex)
{
return null;
}
}
我的项目名称叫做 FuelTicketImageRetrievalSvc 。我已通过项目中的Web设置验证了IIS Express正在使用并设置为
http://localhost:11581/
url路径调用。
http://localhost:11581/FuelTicketImageRetrievalSvc/api/GetSpecificFuelTicket
答案 0 :(得分:1)
要快速保证运行(有时是首选方法),请在方法之前添加HTTP操作前缀和路由属性:
[HttpGet]
[Route("api/Products/SpecificFuelTicket")]
public string GetSpecificFuelTicket()
{
try
{
return null;
}
catch (Exception ex)
{
return null;
}
}
现在,您可以使用以下网址访问它:
http://localhost:xxxx/api/products/SpecificFuelTicket
注意事项:
对于Charles的另一个问题,如果你想使用URL“localhost:xxxx / api / GetSpecificFuelTicketAsync / 6460194”,并且你的方法签名采用int,你可以改变路由前缀如下(再次,不使用“Get” “在路线上):
[HttpGet]
[Route("api/Products/SpecificFuelTicket/{value}")]
public string GetSpecificFuelTicket(int value)
{
try
{
return "Your ticket is " + value.ToString();
}
catch (Exception ex)
{
return null;
}
}
然而,正如Charles所说,使用“ api / Products / SpecificFuelTicket?value = 6460194 ”格式可能更好。方法中的任何参数名称都会自动映射到类似的名称查询参数。所以,你的方法看起来像:
[HttpGet]
[Route("api/Products/SpecificFuelTicket")]
public string GetSpecificFuelTicket(int value)
{
....
}

您在uri中不需要FuelTicketImageRetrievalSvc
,它应该只与/api/...
一起使用
这就是你的路线匹配,有svc名称导致它不匹配。
答案 2 :(得分:0)
您需要在路径中添加控制器并删除项目
http://localhost:11581/api/FuelTicketImageRetrieval/GetSpecificFuelTicket
在引用它时删除Controller部件 - / FuelTicketImageRetrieval /来自FuelTicketImageRetrievalController而不是项目。在寻找正确的类时,Web API会自动将控制器添加回名称。

当我向我的Mvc解决方案添加WebApi支持时,我最初遇到了404错误。
我的global.asax.cs包含以下行:
AreaRegistration.RegisterAllAreas();
FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
RouteConfig.RegisterRoutes(RouteTable.Routes);
BundleConfig.RegisterBundles(BundleTable.Bundles);
GlobalConfiguration.Configure(WebApiConfig.Register);
我发现当我更改WebApiConfig行时,代码块变为:
AreaRegistration.RegisterAllAreas();
GlobalConfiguration.Configure(WebApiConfig.Register);
FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
RouteConfig.RegisterRoutes(RouteTable.Routes);
BundleConfig.RegisterBundles(BundleTable.Bundles);
它解决了我的问题
