Web Api找到了多个动作

Question

我有不同类型参数的动作.

public class MyController : ApiController
{       
    [HttpPost]
    public UpdateFeatureResponse UpdateFeature(UpdateFeatureResuest reqResuest)
    {
        return new UpdateFeatureResponse { IsSuccess = true };
    }

    [HttpPost]
    public DeleteFeatureResponse DeleteFeature(DeleteFeatureRequest request)
    {
        return new DeleteFeatureResponse{ IsSuccess = true };
    }

}

我的请求类型是这样的:

public class UpdateFeatureResuest
{
    public int Id { get; set; }
    public string Feature { get; set; }
}

public class UpdateFeatureResponse
{
    public bool IsSuccess { get; set; }
}

public class DeleteFeatureRequest
{
    public int Id { get; set; }
}

public class DeleteFeatureResponse
{
    public bool IsSuccess { get; set; }
}

路线在这里:

config.Routes.MapHttpRoute(
    name: "DefaultApi",
    routeTemplate: "api/{controller}/{id}",
    defaults: new { id = RouteParameter.Optional }
);

当我http://localhost:52285/api/My/UpdateFeature通过fiddler 发送request()时,它返回HTTP/1.1 500内部服务器错误

错误信息是:

{"message":"发生了错误.","exceptionMessage":"找到了与请求匹配的多个操作:类型为WebGUI.Controllers.MyController的类型为WebGUI.Controllers.MyController\r \nDeleteFeature的\ r \nUpdateFeature" ,"exceptionType":"System.InvalidOperationException","stackTrace":".....

您的路线是错误的，因为它没有指定操作名称，因此它将该UpdateFeature部分视为 ID 参数。改成这样：

config.Routes.MapHttpRoute(
    name: "DefaultApi",
    routeTemplate: "api/{controller}/{action}/{id}",
    defaults: new { id = RouteParameter.Optional }
);
