一、python代码
以下代码可自用，未经允许不可转载
下面的代码是基于pikachu的漏洞平台SQL-Inject的布尔盲注关卡开发的，主要目的是缩短手工盲注的时间，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。
使用前需要根据实际情况修改payload和部分参数（见注释）

二、使用方法
1、下载
（1）比较简单的方法
从我的github打包下载源代码：
下载链接：https://github.com/JacquelinXiang/sqli_blind/archive/refs/heads/main.zip
建议不要直接点击，会很慢，还可能连不上。可以把下载链接丢到github下载加速器里面去下载。
下载下来的文件夹改名为 sqli_blind
（2）比较复杂的方法
a、复制粘贴上面的代码保存为sqli_bb.py
b、复制粘贴下面的代码，保存为__init__.py
from .sqli_bb import *
2、使用
（1）确保有python3环境，没有的话需要安装
（2）根据实际情况修改代码中的payload和部分参数（见备注）
（3）打开命令行，进入sql_blind文件夹的上级目录，输入python进入python3的交互界面
（4）输入 from sqli_blind import * 导入所有函数，然后调用函数即可，具体见测试部分
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
