玩过pikachu漏洞靶场的有木有觉得上面的payload很熟悉？以上代码是在做pikachu的基于时间的sql盲注的过程中开发的，示例payload用的都是这个关卡相关的。
因此在其他地方使用之前需要修改payload和部分参数（见注释）。
写这个小东西的目的主要是缩短手工盲注的时间，从函数名称就能看出来，它可以实现当前数据库名称，表名称，列名称，数据库内容的爆破。
二、使用方法
1、获取
（简单方法）
可以直接从我的github上打包下载代码，布尔盲注和时间盲注都在里面
下载链接：https://github.com/JacquelinXiang/sqli_blind/archive/refs/heads/main.zip
下载链接可以直接添加到各种加速网站，就不用打开github了。
下载下来的文件夹改名为sqli_blind
（复杂方法）
step1、复制上面的代码保存为sqli_tb.py
step2、复制下面的代码保存为__init__.py
from .sqli_tb import *
step3、以上两个python文件保存到文件夹sqli_blind中
2、使用
（1）确保安装了python3
（2）根据实际情况修改代码中的payload和部分参数（见注释）
（3）打开命令行，进入sql_blind文件夹的上级目录，输入python进入python3交互界面
（4）输入 from sqli_blind import *导入所有函数，然后调用函数即可，详见测试部分。
注意：每次修改代码需要退出python3交互界面，删除sqli_blind下的__pycache__文件夹，并重新进入python3交互界面from sqli_blind import *
三、测试
