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

问题 We're running Atomic Secured Linux, and it's been catching posts that are sending NULL bytes in the recaptcha_response_field. The posts in question are definitely spammy, but the only field that gets null bytes is "recaptcha_response_field". In particular, the following is present twice in the POST body: recaptcha_response_field=%00%00%00%00%00%00%00%00 I'm wondering if this is a known attack against recaptcha, or otherwise a known method of compromising web servers. And if so, what it's

问题 I'm not sure why this is happening, and it isn't the usual, common error of: Uncaught SecurityError: Block a frame with origin. The error I'm getting is: Uncaught DOMException: Blocked a frame with origin "https://www.google.com" from accessing a cross-origin frame. I'm following Google's instructions on how to enable ReCaptcha, but it isn't working for me! // top of the page <script src="https://www.google.com/recaptcha/api.js" async defer></script> // then somewhere in the bottom <div class

问题 I have the following code which sends emails out. Is this good/secure enough for a production environment. i.e. will it stop bots, curl scripts sending spam using it, and stop email injections etc etc? <?php require_once('recaptchalib.php'); $privatekey = "private keys goes here"; $resp = recaptcha_check_answer ($privatekey, $_SERVER["REMOTE_ADDR"], $_POST["recaptcha_challenge_field"], $_POST["recaptcha_response_field"]); if (!$resp->is_valid) { // What happens when the CAPTCHA was entered

问题 Live Examples: Without AJAX With AJAX (click Email Us link) When I view the source page everything works fine, but when I load through an AJAX request, in the place where the reCAPTCHA should be, I see... <noscript> <iframe src="http://www.google.com/recaptcha/api/noscript?k=6LfwkccSAAAAALr_z6vDBqkySowo5KIiR0mVM1BX" height="300" width="500" frameborder="0"></iframe><br/> <textarea name="recaptcha_challenge_field" rows="3" cols="40"></textarea> <input type="hidden" name="recaptcha_response

问题 I have a wordpress blog and I had the Captcha plugin on it for the longest time because it worked. Lately though I am getting mass amounts of spam. I then tried to do a "Add These Random Numbers Together" that were generated via PHP but still no luck. I'm not quite sure what I need to do to block this spam but it is quite annoying. I was reading about some kind of visual script that spammers use - that reads your webpage or something thats why Captcha has the messy images to block this sort

问题 I made some changes to ReCaptcha\RequestMethod\Post.php from Google API class Post implements RequestMethod { /** * URL to which requests are POSTed. * @const string */ const SITE_VERIFY_URL = 'https://www.google.com/recaptcha/api/siteverify'; /** * Submit the POST request with the specified parameters. * * @param RequestParameters $params Request parameters * @return string Body of the reCAPTCHA response */ public function submit(RequestParameters $params) { /** * PHP 5.6.0 changed the way
