android 破解验证码登录
1.添加依赖库
compile 'com.rmtheis:tess-two:6.2.0'
2.下载文字库,解压放到手机文件夹根目录
下载地址: http://download.csdn.net/download/qq_33063279/10231538
下完之后需要放入到手机根目录
先看网页的js源码 ,注意这几个字段,后期需要赋值:
可以看到验证码其实是一个url,破解时其实就是访问一次该页面,然后带着返回的cookie再请求验证码的url,拿到图片之后进行识别,识别完了再返回webView里面通过注入js方式将用户名,用户密码和验证码赋值,然后执行js里面的login方法
下面上代码:
