Php 需要实施recaptcha
有人能帮我在这个代码上添加recaptcha吗 这是我的php注册表Php 需要实施recaptcha,php,recaptcha,Php,Recaptcha,有人能帮我在这个代码上添加recaptcha吗 这是我的php注册表 //if form has been submitted process it if(isset($_POST['submit'])){ //very basic validation if($_POST['username'] == ''){ $error[] = 'Username is required.'; }else if(strlen($_POST['username']) < 6){ $e

这里是集成ReCaptcha 2.0的说明。我刚刚在我的网站上测试了一下,效果不错
标记中插入此项以调用Google reCAPTCHA API
<script src="https://www.google.com/recaptcha/api.js" async defer></script>
执行检查的最简单代码是:
<?php
$siteKey = 'your_public_key'; //ex. 6OfGWERRRRt17YkojJGk2mEeM8fgEPKSpiPe
$secret = 'your_private_key';
$recaptcha = new \ReCaptcha\ReCaptcha($secret);
$resp = $recaptcha->verify($_POST['g-recaptcha-response'], $_SERVER['REMOTE_ADDR']); //the values for: $gRecaptchaResponse, $remoteIp
if ($resp->isSuccess()) {
echo 'GREAT!'; //insert here the code you'll want to process if the verification is ok or the value you want to return (if this code is inserted in a function)
} else {
$errors = $resp->getErrorCodes();
echo 'NOOPE..'; //print_r($errors): you'll see which is/are the error
}
?>
表单将属性
g-recaptcha-response
传递给PHP脚本;如果你print\r($\u POST['g-recaptcha-response']
或者你print\r($\u POST)
你会看到如果检查结果是肯定的(你没有被标记为机器人),g-recaptcha-response的值是一个很长的字母数字字符串。网上有很多关于recaptcha集成的教程。你用谷歌搜索过吗?有一个我试过了,但我无法植入它。我对php还是新手,我的网站是由别人开发的。我很感谢有人能帮我,我加上这个来阻止垃圾邮件制造者由@Thamilan链接的教程是第一个谷歌结果,但它实际上非常无用和陈旧;至少有几条评论是有用的。在这里,你可以找到更好的解释。我想用一个完整的代码来回答你,但我也在努力
<?php require('path_where_you_uploaded_the_folder/recaptcha/src/autoload.php'); ?>
<?php
$siteKey = 'your_public_key'; //ex. 6OfGWERRRRt17YkojJGk2mEeM8fgEPKSpiPe
$secret = 'your_private_key';
$recaptcha = new \ReCaptcha\ReCaptcha($secret);
$resp = $recaptcha->verify($_POST['g-recaptcha-response'], $_SERVER['REMOTE_ADDR']); //the values for: $gRecaptchaResponse, $remoteIp
if ($resp->isSuccess()) {
echo 'GREAT!'; //insert here the code you'll want to process if the verification is ok or the value you want to return (if this code is inserted in a function)
} else {
$errors = $resp->getErrorCodes();
echo 'NOOPE..'; //print_r($errors): you'll see which is/are the error
}
?>
