放在cookies里面的加密字符串

控制器中代碼

using System;
using System.Collections.Generic;
using System.Linq;
using System.Net;
using System.Web;
using System.Web.Helpers;
using System.Web.Mvc;
namespace WebApplication1.Controllers
 {
 public class HomeController : Controller
  {
  public ActionResult Index()
   {
   return View();
   }
  [HttpPost]
  [MyValidateAntiForgeryToken]
  public ActionResult Index(Person p)
   {
   return Json(true, JsonRequestBehavior.AllowGet);
   }
  }
 public class Person
  {
  public string Name { get; set; }
  public int Age { get; set; }
  }
 public class MyValidateAntiForgeryToken : AuthorizeAttribute
  {
  public override void OnAuthorization(AuthorizationContext filterContext)
   {
   var request = filterContext.HttpContext.Request;
   if (request.HttpMethod == WebRequestMethods.Http.Post)
    {  
    if (request.IsAjaxRequest())
     {
     var antiForgeryCookie = request.Cookies[AntiForgeryConfig.CookieName];
     var cookieValue = antiForgeryCookie != null
      ? antiForgeryCookie.Value
      : null;
     //從cookies 和 Headers 中 驗證防偽標記
     //這里可以加try-catch
     AntiForgery.Validate(cookieValue, request.Headers["__RequestVerificationToken"]);
     }
    else
     {
     new ValidateAntiForgeryTokenAttribute()
      .OnAuthorization(filterContext);
     }
    }
   }
  }
 }

這里注釋掉ajax中防偽標記在請求

$("#save").click(function () {
 $.ajax({
  type: 'POST',
  url: '/Home/Index',
  cache: false,
 //  headers: headers,
  data: { Name: "yangwen", Age: "1" },
  success: function (data) {
   alert(data)
  },
  error: function () {
   alert("Error")
  }
 });
})

默認返回500的狀態(tài)碼。

這里修改ajax中的防偽標記

  $(function () {
 //var token = $('[name=__RequestVerificationToken]');
 //獲取防偽標記
 var token = $('@Html.AntiForgeryToken()').val();
 var headers = {};
 //防偽標記放入headers
 //也可以將防偽標記放入data
 headers["__RequestVerificationToken"] = token+11111111111111111111111111111111111;
 $("#save").click(function () {
  $.ajax({
   type: 'POST',
   url: '/Home/Index',
   cache: false,
    headers: headers,
   data: { Name: "yangwen", Age: "1" },
   success: function (data) {
    alert(data)
   },
   error: function () {
    alert("Error")
   }
  });
 })
})

也是500的狀態(tài)碼。

以上內(nèi)容就是本文的全部敘述，切記ajax中要帶上AntiForgeryToken防止CSRF攻擊，小伙伴們在使用過程發(fā)現(xiàn)有疑問，請給我留言，謝謝！
