c# - Web Api 发现多个操作

Question

我有具有不同类型参数的操作。

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 }
);

当我通过 fiddler 发送请求 (http://localhost:52285/api/My/UpdateFeature) 时，它返回 HTTP/1.1 500 Internal Server Error

错误信息是:

{"message":"An error has occurred.","exceptionMessage":"Multiple actions were found that match the request: \r\nUpdateFeature on type WebGUI.Controllers.MyController\r\nDeleteFeature on type WebGUI.Controllers.MyController","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 UpdateFeature 部分视为 ID 参数。将其更改为:

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