Web API 控制器中的多个 HttpPost 方法 [英] Multiple HttpPost method in Web API controller

问题描述

我开始使用 MVC4 Web API 项目，我有多个 HttpPost 方法的控制器.控制器如下所示:

I am starting to use MVC4 Web API project, I have controller with multiple HttpPost methods. The Controller looks like the following:

控制器

public class VTRoutingController : ApiController
{
    [HttpPost]
    public MyResult Route(MyRequestTemplate routingRequestTemplate)
    {
        return null;
    }

    [HttpPost]
    public MyResult TSPRoute(MyRequestTemplate routingRequestTemplate)
    {
        return null;
    }
}

这里的MyRequestTemplate表示负责处理传入请求的Json的模板类.

Here MyRequestTemplate represents the template class responsible for handling the Json coming through the request.

错误:

当我使用 Fiddler 为 http://localhost:52370/api/VTRouting/TSPRoute 或 http://localhost:52370/api/VTRouting/Route 发出请求时代码> 我收到一个错误:

When I make a request using Fiddler for http://localhost:52370/api/VTRouting/TSPRoute or http://localhost:52370/api/VTRouting/Route I get an error:

找到多个与请求匹配的操作

Multiple actions were found that match the request

如果我删除上述方法之一，它就可以正常工作.

If I remove one of the above method it works fine.

Global.asax

我已尝试修改global.asax 中的默认路由表，但仍然出现错误，我认为我在global.asax 中定义路由时遇到问题.这是我在 global.asax 中所做的.

I have tried modifying the default routing table in global.asax, but I am still getting the error, I think I have problem in defining routes in global.asax. Here is what I am doing in global.asax.

public static void RegisterRoutes(RouteCollection routes)
{
    routes.MapHttpRoute(
        name: "MyTSPRoute",
        routeTemplate: "api/VTRouting/TSPRoute",
        defaults: new { }
    );

    routes.MapHttpRoute(
        name: "MyRoute",
        routeTemplate: "api/VTRouting/Route",
        defaults: new { action="Route" }
    );
}

我正在使用 POST 在 Fiddler 中发出请求，在 RequestBody 中为 MyRequestTemplate 传递 json.

I am making the request in Fiddler using POST, passing json in RequestBody for MyRequestTemplate.

推荐答案

您可以在一个控制器中拥有多个操作.

You can have multiple actions in a single controller.

为此，您必须做以下两件事.

For that you have to do the following two things.

• 首先用 ActionName 属性修饰动作，如

 [ActionName("route")]
 public class VTRoutingController : ApiController
 {
   [ActionName("route")]
   public MyResult PostRoute(MyRequestTemplate routingRequestTemplate)
   {
     return null;
   }

  [ActionName("tspRoute")]
  public MyResult PostTSPRoute(MyRequestTemplate routingRequestTemplate)
  {
     return null;
  }
}

第二个在WebApiConfig文件中定义如下路由.

// Controller Only
// To handle routes like `/api/VTRouting`
config.Routes.MapHttpRoute(
    name: "ControllerOnly",
    routeTemplate: "api/{controller}"               
);


// Controller with ID
// To handle routes like `/api/VTRouting/1`
config.Routes.MapHttpRoute(
    name: "ControllerAndId",
    routeTemplate: "api/{controller}/{id}",
    defaults: null,
    constraints: new { id = @"^d+$" } // Only integers 
);

// Controllers with Actions
// To handle routes like `/api/VTRouting/route`
config.Routes.MapHttpRoute(
    name: "ControllerAndAction",
    routeTemplate: "api/{controller}/{action}"
);
