如何跳过MVC中的ValidateRequest验证

大家好，又见面了，我是你们的朋友全栈君。

MVC中客户端传值到服务器端时，如果客户端字符串含有“</>”字样时就会报“检测到有潜在危险”的错误。

如：从客户端(“test<br/>ttt”)中检测到有潜在危险的 Request.Form 值。

解决办法：在对应的ActionResult 前面加上[ValidateInput(false)]就可以解决，去除验证。

下面是一个富文本的页面源码示例:

<%@ Page Language=”C#” MasterPageFile=”~/Views/Shared/Site.Master” Inherits=”System.Web.Mvc.ViewPage<SNDA.SPM.Web.Models.NewsModel>” %>

<%@ Register Assembly=”FredCK.FCKeditorV2″ Namespace=”FredCK.FCKeditorV2″ TagPrefix=”FCKeditorV2″ %>

<asp:Content ID=”Content2″ ContentPlaceHolderID=”head” runat=”server”>

<h2>UPS后台管理</h2>

<script src=”../../Scripts/jqui/jquery-1.4.2.js” type=”text/javascript”></script>

<script src=”../../Scripts/fckeditor.js” type=”text/javascript”></script>

<script src=”../../Scripts/jquery.validate.js” type=”text/javascript”></script>

</asp:Content>

<asp:Content ID=”Content1″ ContentPlaceHolderID=”MainContent” runat=”server”>

<script type=”text/javascript” language=”javascript”>

    $(document).ready(function() {

        var oFCKeditor = new FCKeditor(‘Content’);

        oFCKeditor.ToolbarSet = “Wiki”;

        oFCKeditor.ReplaceTextarea();

        $(document.forms.item(0)).validate({

            errorClass: “error”,

            rules:

            {

                Title: “required”,

                Content: “required”

            },

            messages:

            {

                Title: “*请输入新闻标题“,

                Content: “*请输入新闻正文“

            }

        });

    });

</script>

    <div title=”软件包名“ style=”margin:10px 10px;“>

        <table width=”100%” border=”0″ id=”elButton1″>

            <tr>

                <td width=”10%”>软件包名</td>

                <td align=”left” style=”font-size:20px;font-weight:bold;“><%= Model.name%></td>

            </tr>

            <tr title=”新闻标题“>

                <td>新闻标题</td>

                <td>

                    <input type=”text” name=”Title” />                   

                </td>           

            </tr>

            <tr><td colspan=”2″>正文</td></tr>

            <tr title=”正文“>

                <td colspan=”2″>

                    <textarea name=”Content” id=”Content” cols=”60″ rows=”6″></textarea>

                </td>

            </tr>

            <tr title=”Buttons” style=”height:34px;“>

                <td valign=”bottom” align=”right”><input type=”submit” style=”width:80px;height:25px;“ value=”发布“ /></td>

                <td>

                    <%= Html.ActionLink(” “, “Index”, new { id = Model.sid })%>                  

                </td>           

            </tr> 

        </table>       

    </div>       

</asp:Content>
