如何管理AMP-Access-Control-Allow-Source-Origin标头？

Question

在我们网站上的两个页面上，我基本上具有相同的PHP脚本。一种形式完美无瑕，另一种形式则引发以下错误： *响应必须包含AMP-Access-Control-Allow-Source-Origin标头 *表单提交失败：错误：响应必须包含AMP-Access-Control-Allow-Source-Origin标头

预订表格不起作用

<?php
if(isset($_POST['email'])) {
    header("access-control-allow-credentials:true");
    header("access-control-allow-headers:Content-Type, Content-Length, Accept-Encoding, X-CSRF-Token");
    header("access-control-allow-methods:POST, GET, OPTIONS");
    header("access-control-allow-origin:".$_SERVER['HTTP_ORIGIN']);
    header("access-control-expose-headers:AMP-Access-Control-Allow-Source-Origin");
    header("amp-access-control-allow-source-origin:https://".$_SERVER['HTTP_HOST']);
    header("Content-Type: application/json");

    $email_to = "kevin@domain.com.tw;jypbobwr@mydomain.io";
    $email_subject = "Booking Form";

    $date = date('Y-m-d H:i:s');
    $name = $_POST['name'];
    $telephone = $_POST['telephone'];
    $event = $_POST['event'];
    $time = $_POST['time'];
    $guests = $_POST['guests'];
    $highchair = $_POST['highchair'];
    $ipaddress = $_SERVER['REMOTE_ADDR'];
    $output = ['name' => $name];
    $output = ['telephone' => $telephone];
    $output = ['event' => $event];
    $output = ['time' => $time];
    $output = ['guests' => $guests];
    $output = ['highchair' => $highchair];
    $output = ['ipaddress' => $ipaddress];
    echo json_encode($output);
    }

    function clean_string($string) {
      $bad = array("content-type","bcc:","to:","cc:","href");
      return str_replace($bad,"",$string);
    }

    $email_message = "Created: ".clean_string($date)."\n";
    $email_message .= "Name: ".clean_string($name)."\n";
    $email_message .= "Telephone: ".clean_string($telephone)."\n";
    $email_message .= "Event: ".clean_string($event)."\n";
    $email_message .= "Time: ".clean_string($time)."\n";
    $email_message .= "Guests: ".clean_string($guests)."\n";
    $email_message .= "Highchairs: ".clean_string($highchair)."\n";
    $email_message .= "IP: ".clean_string($ipaddress)."\n";


    $headers = 'From: '.$email_to."\r\n".
    'Reply-To: '.$email."\r\n" .
    'X-Mailer: PHP/' . phpversion();
    @mail($email_to, $email_subject, $email_message, $headers);  
?>

这种餐饮形式非常有用

<?php
if(isset($_POST['email'])) {
    header("access-control-allow-credentials:true");
    header("access-control-allow-headers:Content-Type, Content-Length, Accept-Encoding, X-CSRF-Token");
    header("access-control-allow-methods:POST, GET, OPTIONS");
    header("access-control-allow-origin:".$_SERVER['HTTP_ORIGIN']);
    header("access-control-expose-headers:AMP-Access-Control-Allow-Source-Origin");
    header("amp-access-control-allow-source-origin:https://".$_SERVER['HTTP_HOST']);
    header("Content-Type: application/json");

    $email_to = "kevin@domain.com.tw;jypbobwr@mydomain.io";
    $email_subject = "Catering Form";

    $date = date('Y-m-d H:i:s');
    $name = $_POST['name'];
    $email = $_POST['email'];
    $telephone = $_POST['telephone'];
    $company = $_POST['company'];
    $vat = $_POST['vat'];
    $address = $_POST['address'];
    $event = $_POST['event'];
    $time = $_POST['time'];
    $comments = $_POST['comments'];
    $ipaddress = $_SERVER['REMOTE_ADDR'];
    $output = ['name' => $name];
    $output = ['email' => $email_from];
    $output = ['telephone' => $telephone];
    $output = ['company' => $company];
    $output = ['vat' => $vat];
    $output = ['address' => $address];
    $output = ['event' => $event];
    $output = ['time' => $time];
    $output = ['comments' => $comments];
    $output = ['ipaddress' => $ipaddress];
    echo json_encode($output);
    }

    function clean_string($string) {
      $bad = array("content-type","bcc:","to:","cc:","href");
      return str_replace($bad,"",$string);
    }

    $email_message = "Created: ".clean_string($date)."\n";
    $email_message .= "Name: ".clean_string($name)."\n";
    $email_message .= "Email: ".clean_string($email)."\n";
    $email_message .= "Telephone: ".clean_string($telephone)."\n";
    $email_message .= "Company: ".clean_string($company)."\n";
    $email_message .= "VAT: ".clean_string($vat)."\n";
    $email_message .= "Address: ".clean_string($address)."\n";
    $email_message .= "Event: ".clean_string($event)."\n";
    $email_message .= "Time: ".clean_string($time)."\n";
    $email_message .= "Comments: ".clean_string($comments)."\n";
    $email_message .= "IP: ".clean_string($ipaddress)."\n";


    $headers = 'From: '.$email_to."\r\n".
    'Reply-To: '.$email."\r\n" .
    'X-Mailer: PHP/' . phpversion();
    @mail($email_to, $email_subject, $email_message, $headers);  
?>

我正在拔头发。我可以看到没有理由不起作用。
