recaptcha

问题 I am implementing reCAPTCHA on one of my websites and I have successfully implemented it. It is working fine. Sometime the reCAPTCHA gets completed only by clicking the "I'm not a Robot" but sometimes it shows the images grid to select the correct images and complete the captcha. I was just wondering if this possible or not. Can we disable the images selection challenge so the reCAPTCHA can be completed only by clicking the "I'm not a Robot". What is the theory of Google for showing the

问题 I need to show only the numeric reCaptha instead of character strings. Is it possible? If yes, please give the procedure. Like Google's Street view 回答1: It is not possible at the moment. Your only options for customisation are basically just skins/themes. If such an option were available, it would also not be in the options passed through on the client side as a bot could just request it as an easier alternative. Even the plugins only generate javascript to display the widget. So the option

问题 My previous question on StackOverflow was about that someone was sending me hundreds of spam emails every few hours. Now, I fixed the script on the server side but the next morning I still got 30 emails or something and my hosting company gave me a new password to my FTP and moved my index files to a backup map(website offline), they said it was hacked because of the suspicious script below. They said "This often happens via a leaked script in your website, a script that is "out of date".

问题 I just need to configure reCaptcha, so it is only display numbers as display text, no word as display text. I need do this configuration in NopCommerce [3.1] 回答1: Google uses "advanced risk analysis techniques, actively considering the user’s entire engagement with the CAPTCHA" to determine how difficult of a puzzle the user deserves. So there is not configuration setting and most users get simple numbers by default. Source: http://googleonlinesecurity.blogspot.com/2013/10/recaptcha-just-got

问题 I'm using the new Google reCaptcha API for a contact form inside a page on my wordpress instance, but the API returns a 500 Internal Server Error message when using the script given by Google. So, I'm using this code to make it work $siteKey = "sitekey"; $secret = "secretkey"; $lang = "it"; $resp = null; $error = null; $reCaptcha = new ReCaptcha($secret); if ($_POST["g-recaptcha-response"]) { $resp = $reCaptcha->verifyResponse( $_SERVER["REMOTE_ADDR"], $_POST["g-recaptcha-response"] ); } and,

问题 I want to hide the border of a recaptcha v2.0 widget so that I can better visually integrate it into my site's look and feel. NOTE: I'm posting this as a question, and providing a solution, because most of the StackOverflow questions I've found on the topic center around removing the frameborder attribute of the recaptcha's iframe, which isn't technically what I'm after. I'm after the result of that -- an edgeless recaptcha widget that I can position within a larger visual context. I hope

问题 I am loading Invisible reCAPTCHA dynamically for every form with button that has class g-recaptcha . Problem that I have is that captcha is not loading correctly and I am not sure why. I followed documentation on captcha website and I am not sure how and why I got this error: Uncaught Error: Missing required parameters: sitekey Does someone knows where is the problem? Here is code I use: <script src='https://www.google.com/recaptcha/api.js?onload=onloadCallback&hl={{ app.request.locale

问题 I am attempting to implement the secure token version of Googles Recaptcha v2, I have successfully implemented the single site version. The issue is we will need multiple domains to validate with the same key. Following the documentation here, has left me scratching my head. The "Encrypt your string" area is a bit vague for a new user (me). I have tried using standard AES encryption with my own salt but with no luck, I am met with ERROR: Invalid stoken Working with this post AES encryption

问题 I do site verification after getting g-recaptcha-response thru user verification. I send xhr POST with parameters and get 200 OK, yet NO response as it should be: { "success": true|false, "error-codes": [...] // optional } Code <script type='text/javascript'> var onReturnCallback = function(response) { document.getElementById('resp').innerHTML = response; // works well //alert('grecaptcha.getResponse() = ' + grecaptcha.getResponse()); // works well too $.post("https://www.google.com/recaptcha
