Anti-XSS

msi安装程序，安装之后，安装目录下有以下文件
AntiXSS.chm   包括类库的操作手册参数说明
HtmlSanitizationLibrary.dll    包含Sanitizer类(输入白名单)
AntiXSSLibrary.dll    包含Antixss，Encoder类(输出转义)
使用时在工程内添加引用HtmlSanitizationLibrary.dll 和AntiXSSLibrary.dll
导入命名空间using Microsoft.Security.Application;
 
1、输入白名单
调用Sanitizer.GetSafeHtmlFragment方法即可,url_c未过滤后的干净字串
 
            url = Request.QueryString["url"];
            url_c = Sanitizer.GetSafeHtmlFragment(url);
            Response.Write(url_c);
2、输出转义
 
            //HTML内容编码
            html_cont = Encoder.HtmlEncode(url);
            //html_cont = url;
 
            //HTML属性编码
            input1.Value = Encoder.HtmlAttributeEncode(url);
            //input1.Value = url;
 
            //对js进行编码
            url_c = Encoder.JavaScriptEncode(url);
            //url_c = url;
 
            //URL编码
            img1.Src = Encoder.UrlEncode(url);
            //img1.Src = url;
 
            //XML属性编码
            isbn = Encoder.XmlAttributeEncode(Request.QueryString["isbn"]);
        
             //XML内容编码
            price = Encoder.XmlEncode(Request.QueryString["price"]);
            price = Request.QueryString["price"];
