推荐答案
首先请确保您已包含正确渲染reCAPTCHA小部件所需的JavaScript资源，如下所示：
First of all make sure that you've included the necessary JavaScript resource to render reCAPTCHA widget properly, like this:
<html>
<head>
<title>reCAPTCHA demo: Simple page</title>
<script src="https://www.google.com/recaptcha/api.js" async defer></script>
</head>
<body>
<form action="?" method="POST">
<div class="g-recaptcha" data-sitekey="your_site_key"></div>
<br/>
<input type="submit" value="Submit">
</form>
</body>
</html>
以下是参考资料：
- Displaying the widget
现在来看你的用户的回复。用户的验证码挑战的响应可以通过三种方式获取。它可以是，
Now comes to your user's response. The response from the user's captcha challenge can be fetched in three ways. It can be as,
- g-recaptcha-response - 提交表单中的POST参数
- grecaptcha.getResponse（widget_id） - 将在用户完成验证码后提供响应。
- 回调的字符串参数传递给render方法的config对象中指定的函数。
- g-recaptcha-response - a POST parameter in the submitted form
- grecaptcha.getResponse(widget_id) - will provide the response after the user completes the captcha.
- A string argument to the callback function specified in the config object passed to the render method.
这是引用：
- Verifying the user's response
为了您的目的，使用 grecaptcha.getResponse（）来获取用户的回复。
For you purpose use grecaptcha.getResponse() to get the user's response.
作为旁注使用 grecaptcha.reset（）来要求最终用户再次使用reCAPTCHA进行验证。来自手册：
And as a sidenote use grecaptcha.reset() to ask the end user to verify with reCAPTCHA again. From the manual:
如果您的网站使用AJAX请求执行服务器端验证，您应该只验证用户的reCAPTCHA响应令牌（ g-recaptcha-response ）一次。如果使用特定令牌进行了验证尝试，则无法再次使用它。您需要致电 grecaptcha.reset（），要求最终用户再次通过reCAPTCHA验证。
If your website performs server side validation using an AJAX request, you should only verify the user’s reCAPTCHA response token (g-recaptcha-response) once. If a verify attempt has been made with a particular token, it cannot be used again. You will need to call grecaptcha.reset() to ask the end user to verify with reCAPTCHA again.
这是您的 HTML 代码：
<form method = "POST" name = "register" id = "register" class="m-t" role="form" action="login.html">
<div class="form-group">
<input type="text" name = "fname" id = "fname" class="form-control" placeholder="First Name" required="">
</div>
<div class="form-group">
<input type="text" name = "lname" id = "lname" class="form-control" placeholder="Last Name" required="">
</div>
<div class="form-group">
<input type="email" name = "email" id = "email" class="form-control" placeholder="Email" required="">
</div>
<div class="form-group">
<input type="password" name = "password" id = "password" class="form-control" placeholder="Password" required="">
</div>
<div class="form-group">
<input type="mobile" name = "mobile" id = "mobile" class="form-control" placeholder="Mobile No" required="">
</div>
<div class="form-group" id="recaptcha_widget">
<div class="required">
<div class="g-recaptcha" data-sitekey="XXXXXX_SITE-KEY_XXXXXXX"></div>
<!-- End Thumbnail-->
</div>
</div>
<button type="submit" name = "submit" id = "submit" class="btn btn-primary block full-width m-b">Register</button>
</form>
<p class="text-muted text-center"><small>Already have an account?</small></p>
<a class="btn btn-sm btn-white btn-block" href="login.html">Login</a>
您的 jQuery 应如下所示：
$(document).ready(function(){
//execute's the function on click
$("#submit").click(function(e){
var recaptchaResponse = grecaptcha.getResponse();
var status = $('form')[0].checkValidity();
if(status){
/*jquery to call the url requested
and parse the data in json*/
$.ajax({
url: "process.php",
type: "POST",
data: {
fname: $("#fname").val(),
lname: $("#lname").val(),
email: $("#email").val(),
password: $("#password").val(),
mobile: $("#mobile").val(),
recaptchaResponse: recaptchaResponse
},
async: false,
dataType: "JSON",
/*Give out the alert box
to display the results*/
success: function (json){
if(json.error){
alert(json.error_msg);
grecaptcha.reset();
e.preventDefault();
}else{
alert("Registeration successful!",json.user.email);
$('#register').submit();
}
},
error: function(jqXHR, textStatus, errorThrown){
alert(errorThrown);
}
});
}
});
});
最后你的 PHP 应该是这样的：
And finally your PHP should be like this:
<?php
// your code
//your site secret key
$secret = 'XXXXXXX_Secret-key_XXXXXXX';
if(isset($_POST['recaptchaResponse']) && !empty($_POST['recaptchaResponse'])){
//get verified response data
$param = "https://www.google.com/recaptcha/api/siteverify?secret=".$secret."&response=".$_POST['recaptchaResponse'];
$verifyResponse = file_get_contents($param);
$responseData = json_decode($verifyResponse);
if($responseData->success){
// success
}else{
// failure
}
}
// your code
?>
