授权属性和jQuery AJAX在asp.net MVC [英] Authorize attribute and jquery AJAX in asp.net MVC
问题描述
我已经使用jQuery的AJAX功能提交表单。 则用户必须先登录否则,他们必须重定向到登录page.I已经使用授权()属性了。
I have used jquery ajax function to submit a form. The users have to be logged in else they must redirect to a login page.I have used Authorize() attribute for it.
[Authorize]
public ActionResult Creat()
{
....
}
如果用户没有登录的动作返回登录页面jQuery的AJAX功能,它是显示在同一页面上,但我希望将用户重定向到登录页面。 有没有什么解决办法吗?
If the user is not login the action return login page to jquery's ajax functions and it is displayed on the same page but I want to redirect the user to login page. Is there any solution?
推荐答案
工作例如:<一href="https://github.com/ronnieoverby/mvc-ajax-auth">https://github.com/ronnieoverby/mvc-ajax-auth
重要部分:
AjaxAuthorizeAttribute:
AjaxAuthorizeAttribute:
using System.Web.Mvc;
namespace MvcApplication1
{
public class AjaxAuthorizeAttribute : AuthorizeAttribute
{
protected override void HandleUnauthorizedRequest(AuthorizationContext context)
{
if (context.HttpContext.Request.IsAjaxRequest())
{
var urlHelper = new UrlHelper(context.RequestContext);
context.HttpContext.Response.StatusCode = 403;
context.Result = new JsonResult
{
Data = new
{
Error = "NotAuthorized",
LogOnUrl = urlHelper.Action("LogOn", "Account")
},
JsonRequestBehavior = JsonRequestBehavior.AllowGet
};
}
else
{
base.HandleUnauthorizedRequest(context);
}
}
}
}
JavaScript的:
Javascript:
$(function () {
$(document).ajaxError(function (e, xhr) {
if (xhr.status == 403) {
var response = $.parseJSON(xhr.responseText);
window.location = response.LogOnUrl;
}
});
});
使用属性的控制器:
[AjaxAuthorize]
public ActionResult Secret()
{
return PartialView();
}
做一些Ajax:
Do some ajax:
@Ajax.ActionLink("Get Secret", "Secret", new AjaxOptions { UpdateTargetId = "secretArea", })
<div id="secretArea"></div>
