Question

登陆豆瓣，发现要填写验证码，原来是想把验证码每次保存到本地手动填写，但是发现验证码的路劲一直在自动变化？如第一次是：https://www.douban.com/misc/captcha?id=t...
第二次变化为：https://www.douban.com/misc/captcha?id=q...，请问这种情况怎么办啊

Answer 1

So, you want to request a picture of the verification code yourself?

In fact, this change in URL is not called a change in the path, because id=tXP2X8xc0zBtyL1qUSgnBhbG:en&size=sThis section is the parameter carried by the request. That is:

{
id = "tXP2X8xc0zBtyL1qUSgnBhbG:en",
size = "s"
}

In fact, you can first request the login page, then parse the html or directly find the address of the verification code via regular expressions <img src="" >
Then request this image and store it locally.
