验证码不在jquery端进行验证
首先，请确保您已包含必要的JavaScript资源以正确呈现reCAPTCHA小部件，如下所示：
<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 data-sitekey="your_site_key"></div>
<br/>
<input type="submit" value="Submit">
</form>
</body>
</html>
这是参考：
- 显示小部件
现在是用户的响应。用户验证码质询的响应可以三种方式获取。可以是
- 提交表单中的POST参数
- -在用户完成验证码输入后将提供响应。
- 传递给render方法的config对象中指定的回调函数的字符串参数。
这是参考：
- 验证用户的响应
出于您的目的，请使用 获取用户的响应。
作为旁注，请使用 要求最终用户再次使用reCAPTCHA进行验证。从手册中：
如果您的网站使用AJAX请求执行服务器端验证，则应该只验证一次用户的reCAPTCHA响应令牌（ ）。如果使用特定令牌进行了验证尝试，则无法再次使用它。您将需要调用 来要求最终用户再次使用reCAPTCHA进行验证。
这是您的 代码：
<form method = "POST" name = "register" id = "register" role="form" action="login.html">
<div>
<input type="text" name = "fname" id = "fname" placeholder="First Name" required="">
</div>
<div>
<input type="text" name = "lname" id = "lname" placeholder="Last Name" required="">
</div>
<div>
<input type="email" name = "email" id = "email" placeholder="Email" required="">
</div>
<div>
<input type="password" name = "password" id = "password" placeholder="Password" required="">
</div>
<div>
<input type="mobile" name = "mobile" id = "mobile" placeholder="Mobile No" required="">
</div>
<div id="recaptcha_widget">
<div>
<div data-sitekey="XXXXXX_SITE-KEY_XXXXXXX"></div>
<!-- End Thumbnail-->
</div>
</div>
<button type="submit" name = "submit" id = "submit">Register</button>
</form>
<p><small>Already have an account?</small></p>
<a href="login.html">Login</a>
您的 应该是这样的：
$(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，您的 应该是这样的：
<?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
?>
解决方法
我正在使用php来验证google REcaptcha
..就后端验证而言，如果验证码未提交并且完成的用户存储在数据库中，但是当我将其与jquery连接时出现主要问题，则会给出错误提示。
..问题是，即使验证码在后端经过验证，每次也总是发出错误“您缺少的验证码”，请帮帮我，如果有错，请原谅我.. !!
