1.不要频繁运行程序模拟登录
频繁模拟登录并识别验证码后，会出现验证码却来越模糊到难以识别，并且识别后点击"确认"按钮无法登录（或者说登录按键失效的）的情况。如图所示的位置失效：
2.超级鹰
超级鹰打码平台 打码效率可以达到90%以上。在平台上注册绑定微信后会赠送1000积分，基本够用了。如图是我的积分情况：
3.超级鹰软件ID和验证码类型
软件ID相当于工作牌(或护照)，每次打码都必须携带；验证码类型需要你去 平台 确认。例如该项目的验证码类型属于9004 坐标多选,返回1~4个坐标。
4.识别思路(简要)
首先，获取验证码位置并获取网页截图；然后，裁剪获取验证码图像并以字节流的格式发送给超级鹰打码平台；最后，转化识别结果并使用Selenium点击登录。
