我正在尝试为联系页面安装Google reCaptcha,而我对php的知识非常有限 . 我不确定谷歌要求的信息应该放在我的php文件中 . 以下是Google对此的说明:
当您的用户提交集成reCAPTCHA的表单时,您将获得有效负载的一部分,其名称为“g-recaptcha-response” . 要检查Google是否已验证该用户,请发送包含以下参数的POST请求:网址:https://www.google.com/recaptcha/api/siteverify secret(required) - xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx response(required) - 值'G-验证码 - 响应' . remoteip - 最终用户的IP地址 .
这是我使用的表单的PHP .
<?php
$secret = 'SECRET KEY HERE';
$verificationResponse = $_POST["g-recaptcha-response"];
$response = file_get_contents("https://www.google.com/recaptcha/api/siteverify?secret=".$secret."&response=".$verificationResponse);
$response = json_decode($response, true);
if($response["success"] === true){
// actions if successful
}else{
// actions if failed
}
/* Set e-mail recipient */
$myemail = "info@thewiseinvestor.net";
/* Check all form inputs using check_input function */
$name = check_input($_POST['inputName'], "First and Last");
$email = check_input($_POST['inputEmail'], "Required");
$phone = check_input($_POST['inputPhone']);
$message = check_input($_POST['inputMessage'], "Brief Description");
/* If e-mail is not valid show error message */
if (!preg_match("/([\w\-]+\@[\w\-]+\.[\w\-]+)/", $email))
{
show_error("Invalid e-mail address");
}
/* Let's prepare the message for the e-mail */
$subject = "Contact Message from thewiseinvestor.net";
$message = "
Someone has sent you a message using your contact form:
Name: $name
Email: $email
Phone: $phone
Message:
$message
";
/* Send the message using mail() function */
mail($myemail, $subject, $message);
/* Redirect visitor to the thank you page */
header('Location:contact.html');
exit();
/* Functions we used */
function check_input($data, $problem='')
{
$data = trim($data);
$data = stripslashes($data);
$data = htmlspecialchars($data);
if ($problem && strlen($data) == 0)
{
show_error($problem);
}
return $data;
}
function show_error($myError)
{
?>
<html>
<body>
<p>Please correct the following error:</p>
<strong><?php echo $myError; ?></strong>
<p>Hit the back button and try again</p>
</body>
</html>
<?php
exit();
}
?>
HTML表单
<div class="row">
<div class="col-md-6 message">
<h2>Send Us A Message</h2>
<form name="contactform" method="post" action="index.php" class="form-vertical">
<div class="form-group">
<label for="inputName" class="control-label">Name</label>
<input type="text" class="form-control" id="inputName" name="inputName" placeholder="First and Last">
</div>
<div class="form-group">
<label for="inputEmail" class="control-label">Email*</label>
<input type="text" class="form-control" id="inputEmail" name="inputEmail" placeholder="Required">
</div>
<div class="form-group">
<label for="inputPhone" class="control-label">Phone Number</label>
<input type="text" class="form-control" id="inputPhone" name="inputPhone" placeholder="Optional">
</div>
<div class="form-group">
<label for="inputMessage" class="control-label">Message</label>
<textarea class="form-control" rows="5" id="inputMessage" name="inputMessage" placeholder="Brief Description"></textarea>
</div>
<div class="g-recaptcha" data-sitekey="DATA SITE KEY HERE"></div>
<div class="form-group">
<button type="submit" class="btn btn-custom pull-right hvr-underline-from-left">Send</button>
</div>
</form>
</div> <!-- end col-md-6 -->
我真的不确定上述信息应该去哪里 . 非常感谢任何帮助 .

谷歌reCaptcha机制在您的表单中注入一个隐藏的IFrame,并将一个散列字符串返回到您的处理脚本,称为“g-recaptcha-response” .
因此,在上面的PHP脚本中,在
/* Set e-mail recipient */
之前,请添加以下内容:应该没有任何问题 . 在检查其他内容或向您发送任何电子邮件之前,代码将检查reCaptcha是否已正确传递 .
祝好运 .
有reCaptcha的官方文档,并准备使用PHP lib .
在这里,您可以找到准备使用的代码和注释:https://github.com/google/recaptcha
您的服务器端代码如下所示:
