在联系表 PHP 文件中安装 Google reCaptcha 的信息
Install Info For Google reCaptcha on Contact Form PHP File
我正在尝试为联系人页面安装 Google reCaptcha，但我对 php 的了解非常有限。我不确定 Google 需要的信息应该放在我的 php 文件中的什么位置。以下是 Google 的说明：
When your users submit the form where you integrated reCAPTCHA, you'll get as part of the payload a string with the name "g-recaptcha-response". In order to check whether Google has verified that user, send a POST request with these parameters:
URL: https://www.google.com/recaptcha/api/siteverify
secret (required) - xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
response (required) - The value of 'g-recaptcha-response'.
remoteip - The end user's ip address.
这是我使用的 php 表格。
<?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();
}
?>

我真的不确定上述信息应该放在哪里。非常感谢任何帮助。
reCaptcha 有官方文档，可以使用 PHP 库。
在这里您可以找到随时可用的代码和注释：
https://github.com/google/recaptcha
您的服务器端代码将如下所示：
<?php
$recaptcha = new \ReCaptcha\ReCaptcha($secret);
$resp = $recaptcha->verify($gRecaptchaResponse, $remoteIp);
if ($resp->isSuccess()) {
// verified!
} else {
$errors = $resp->getErrorCodes();
}
google reCaptcha 机制在您的表单中注入一个隐藏的 IFrame，并 returns 一个散列字符串到您的处理脚本 'g-recaptcha-response'。
因此，在您上面的 PHP 脚本中，请在 /* Set e-mail recipient */ 之前添加以下内容：
<?php
// error_reporting(E_WARNING);
function readURL($url)
{
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$output = curl_exec($ch);
curl_close($ch);
return $output;
}
$secret = "PASTE-YOUR-SECRET-KEY-HERE";
$verificationResponse = $_POST["g-recaptcha-response"];
if( empty($verificationResponse) ) die("Google did not POST the required g-recaptha-response");
$response = readURL("https://www.google.com/recaptcha/api/siteverify?secret=" . $secret . "&response=" . $verificationResponse . "");
$responseArray = json_decode($response, true);
if( $responseArray["success"] !== true) die("Invalid reCaptcha <a href=\"javascript:history.go(-1);\">Try Again</a>");
/* 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();
}
?>
应该可以正常工作。该代码将在检查其他内容或向您发送任何电子邮件之前检查 reCaptcha 是否正确传递。
祝你好运。
