1.key又又找不到了url：http://lab1.xseclab.com/xss1_30ac8668cd453e7e387c76b132b140bb/index.php点击链接，burp抓包，发送到重放模块，点击go得到key is : yougotit_script_now

2.快速口算url：http://lab1.xseclab.com/xss2_0d557e6d2a4ac08b749b61473a075be1/index.phppython3脚本import requests, re
url = 'http://lab1.xseclab.com/xss2_0d557e6d2a4ac08b749b61473a075be1/index.php'
s = requests.session()
c = s.get(url).content
print(c)
c=c.decode('utf-8')#python3一定要加上这一句
r = re.findall(r'[\d]{2,}',c)
r = int(r[0])*int(r[1])+int(r[2])*(int(r[3])+int(r[4]))
c1 = s.post(url, data={'v':r}).content
print(c1.decode('utf-8'))得到key is 123iohHKHJ%^&*(jkh

3.这个题目是空的试了一圈最后发现是null4.怎么就是不弹出key呢？url：http://lab1.xseclab.com/xss3_5dcdde90bbe55087eb3514405972b1a6/index.php先点了链接发现没反应，审查元素后发现一大段js代码，发现a是个匿名函数，代码中还有禁止弹窗的函数，复制下来，删除前面几个函数，修改打印的值，保存成HTML文件，在浏览器打开script>
var a = function () {
var b = function (p, a, c, k, e, r) {
e = function (c) {
return (c a ? '' : e(parseInt(c / a))) + ((c = c % a) > 35 ? String.fromCharCode(c + 29) : c.toString(36))
};
if (!''.replace(/^/, String)) {
while (c--) r[e(c)] = k[c] || e(c);
k = [
function (e) {
return r[e]
}

e = function () {
return '\\w+'
};
c = 1

while (c--) if (k[c]) p = p.replace(new RegExp('\\b' + e(c) + '\\b', 'g'), k[c]);
