除了上面参考文章中介绍的方法,其实在ASP.NET Core MVC的Filter拦截器中要使用UrlHelper非常简单。如下代码就展示了如何在IActionFilter拦截器中构造和使用UrlHelper,其它MVC的Filter拦截器如法炮制即可:
using Microsoft.AspNetCore.Mvc;
using Microsoft.AspNetCore.Mvc.Filters;
using Microsoft.AspNetCore.Mvc.Routing;
using System; namespace WebApi.Filters
{
public class MyActionFilterAttribute : Attribute, IActionFilter
{
/// <summary>
/// OnActionExecuting方法在Controller的Action执行前执行
/// </summary>
public void OnActionExecuting(ActionExecutingContext context)
{
IUrlHelper urlHelper = new UrlHelper(new ActionContext(context.HttpContext, context.RouteData, context.ActionDescriptor)); string actionUrl = urlHelper.Action("Display", "User", new { id = });
} /// <summary>
/// OnActionExecuted方法在Controller的Action执行后执行
/// </summary>
public void OnActionExecuted(ActionExecutedContext context)
{
IUrlHelper urlHelper = new UrlHelper(new ActionContext(context.HttpContext, context.RouteData, context.ActionDescriptor)); string actionUrl = urlHelper.Action("About", "Home", new { id = });
}
}
}
OnActionExecuting方法运行效果如下:
OnActionExecuted方法运行效果如下:
