问题 Is it reasonable (or secure) to validate CAPTCHA via ajax? I want place a sign up form without any page reload. Is it secure? (I am using Validation[1] and Form plugins) [1] http://bassistance.de/jquery-plugins/jquery-plugin-validation/ 回答1: You cannot rely on JavaScript to secure anything.

问题 I am trying to automate one form where I get re-Captcha as a part of form submission. I got stuck and figuring out that how can we handle the captcha text using selenium webdriver. Though this captcha is turing test implementation in realtime but, still I am finding some way so that I can handle this scenario. 回答1: So you can't really do that, captcha is by definition meant to break your automation. That said, I have had some luck using Tesseract OCR, but I was dealing with rather simplistic
