Loadrunner+Tesseract-OCR 识别验证码实现自动注册

2024-08-04 14:58:58 219人阅读

发现一个网站注册时发送给手机的验证码可以直接在网站上展出出来，考虑可以使用LR与OCR结合尝试自动注册

Tesseract-OCR 下载

在code.google上下载tesseract-ocr-setup-3.02.02.exe

安装后实验

http://elearning.yunxuetang.cn/portal/enterpriseregister.htm

填写手机号后等待30秒获得带有验证码的图片

图片另存为test.png

tesseract test.png out

loadrunner使用tesseract-ocr时需要通过bat实现

bat内容如下

----------------------------------------------------------------------------------------

c:
cd\
tesseract.exe test.png out digits

----------------------------------------------------------------------------------------

------------------在config中修改digits文件，将1234567890加入则只识别数字--------------

参数设置

执行结果

登录页面http://18888888888.yunxuetang.cn/login.htm

换一个不存在的http://18888888890.yunxuetang.cn/login.htm，应该是跳到了一个固定的网页。
