带有验证码的模拟登录两种方式post和selenium

首先是验证码的识别：

如果验证码图片随着url地址改变而改变，即验证码的url地址是变化的，这种就很好办，直接请求并下载验证码利用打码平台进行验证码图片识别即可
如果验证码图片的url地址不变，而验证码是随机改变的
post方法：设置session进行验证码的get请求并下载图片进行识别得到验证码的识别结果，再利用这个sesson进行post请求，把账号密码和验证码识别结果的表单数据进行post从而模拟登录
selenium方法：利用selenium进行页面打开，并用selenium记录下此时页面的cookies，然后用requests.get()携带这个cookies发送验证码url的请求获取验证码的识别结果，然后进行selenium的操作输入账号密码和验证码

打码平台使用的是超级鹰
