学习视频来源：B站《Web安全渗透全套教程（40集）》
个人在学习的同时，也验证了视频中的实验部分，现将授课笔记和实验笔记整理下来。
SQL注入危害
SQL基础回顾
连接数据库
查看数据库：show databases
进入dvwa数据库
查看表
查看表结构
查看表记录
select * from dvwa.users union select 1,2,3,4,5,6，猜测出系统的字段数量，再用select * from dvwa.users union select user_login,user_pass,1,2,3,4 from wordpress.wp_users; 获取想要的内容（可以增加where 1=3，这样不成立的条件，过滤掉之前的不想要的内容）
information_schema
use information_schema.tables，里面存放了所有数据库和数据表的元信息
select * from information_schema.TABLES\G，查所有库和所有表
select DISTINCT TABLE_SCHEMA from information_schema.TABLES; //等价于show databases
mysql> select DISTINCT TABLE_SCHEMA from information_schema.TABLES;

mysql>SQL注入流程
基于错误的注入
尝试输入'，试探错误，但无法获得信息
基于布尔的注入
第一个'用于闭合前面的条件；or 1=1 为真的条件；--将注释后面的所有语句
基于UNION注入
基于时间的盲注
前面要是真条件
sqlmap自动化注入
GET方法注入
选择OWASP Multillidae II，选择无需登录的页面做注入
输入任意用户名和密码，选择URL，使用sqlmap注入
sqlmap -u注入
扫描成功，会保存到指定目录
sqlmap增加 --dbs，获得所有数据库信息
获得所有用户
获得当前用户
整理的参数
获取指定表的指定列的值
整理的示例
POST方法注入
需要带cookie才能访问的注入页面，--cookie=""
数据获取
提权操作
综合实例
