suppose I only have the login interface now, and I don"t know what the picture looks like.
like login interface picture CAPTCHA parameter: imgcaptcha:xxxx.
I don"t know what the value is.
is it necessary to simulate the login page, get the image verification code to identify the value, and then simulate the login?
answer the last question, yes. Identification picture CAPTCHA is a sub-function of simulated login.
the image verification code is impassable, so you can either identify it or find the code platform.
Yes CAPTCHA is required. You can identify the corresponding CAPTCHA after opening the web page, or you can intercept the request and find the corresponding CAPTCHA API
