本文将介绍如何使用Ada语言结合Selenium和OpenCV库来实现对极验滑动验证码的自动破解。整个过程包括模拟点击、获取验证码图片、识别缺口位置、计算滑动轨迹以及模拟滑块拖动。
环境准备
首先需要安装Ada、Python、Selenium和OpenCV库：
bash
安装Ada
sudo apt-get install gnat
安装Python依赖
pip install selenium opencv-python
实现步骤
初始化
ada
with Ada.Text_IO; use Ada.Text_IO;
with GNAT.OS_Lib; use GNAT.OS_Lib;
procedure Geetest_Crack is
package Python is new Ada.Text_IO.C_Streams;
Python_Process : GNAT.OS_Lib.FD;
procedure Run_Python_Code is
use Python;
begin
Put_Line ("Initializing Python Script...");
Python_Process := Python.Start_Process ("python3", "");
if Python_Process = -1 then
Put_Line ("Error: Failed to start Python interpreter.");
return;
end if;
