一、注意点

本文代码是对着pikachu漏洞靶场的宽字节注入关卡开发的，代码中的payload和参数都基于此，使用本文代码需要修改payload和部分参数，具体见代码注释

比起单纯的布尔盲注，宽字节注入+布尔盲注需要注意以下几点：

（1）payload中布尔运算符后面的语句不能包含单引号等会被转义的特殊字符

（2）requests模块方法的入参必须写成字符串形式，不能是字典形式（原因是字典形式的参数会被requests模块自动进行url编码）

（3）http头必须包含"Content-Type":"application/x-www-form-urlencoded" （原因也是如果没有这个头，requests模块就会自动对参数进行url编码）

三、使用

1、获取

（简单方法）

我的github：

仓库：JacquelinXiang/sqli_blind: A simple tool/framework for boolean-based or time-based sql injection(blind) (github.com)

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_bb_widebyte.py

step2、复制下面的代码保存为__init__.py

from .sqli_bb_widebyte 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 *

四、测试
