Php 获取访问控制允许原始标头的错误

我正在我的网站上尝试贝宝支付方式。 表单提交时，控制台日志中显示错误

Access to XMLHttpRequest at 'https://www.sandbox.paypal.com/cgi-bin/webscr' from origin 'http://localhost' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.

我已经在文件上添加了标题代码

header("Access-Control-Allow-Origin: *");
header("Access-Control-Allow-Credentials: true");
header("Access-Control-Max-Age: 1000");
header("Access-Control-Allow-Headers: X-Requested-With, Content-Type, 
Origin, Cache-Control, Pragma, Authorization, Accept, Accept-Encoding");
header("Access-Control-Allow-Methods: PUT, POST, GET, OPTIONS, DELETE");

并且还添加到apache服务器中

Header set Access-Control-Allow-Origin "*"

但显示出错误。 请帮忙

这是我的原始脚本

<form action="<?php echo $paypalURL; ?>" method="post">

                        <span>What service do yon need?</span><br>

这只是帮助您的代码示例。这样您就可以使用CURL将请求发送到另一台服务器。此处
$posted\u data
将是数组中的所有值

APIURL替换为您的url“”

希望你能了解如何解决你的问题

    try {
        $headers = array(
            'Content-Type: application/json',
        );
        $ch = curl_init();
        $options = array(
            CURLOPT_URL => 'APIURL',
            CURLOPT_HEADER => false,
            CURLOPT_POST => true,
            CURLOPT_HTTPHEADER => $headers,
            CURLOPT_POSTFIELDS => json_encode($posted_data),
            CURLOPT_FAILONERROR => true,
            CURLOPT_FOLLOWLOCATION => true,
            CURLOPT_RETURNTRANSFER => true,
            CURLOPT_SAFE_UPLOAD => false,
            CURLOPT_SSL_VERIFYPEER => false,
        );
        curl_setopt_array($ch, $options);
        $jsonResponse = curl_exec($ch);
        curl_close($ch);

} catch (\Exception $ex) {
    $result['status'] = 0;
    $result['message'] = 'error';
    $result['debug'] = $ex->getMessage();
}

您可以使用CURL，否则必须在发送数据操作的服务器上启用CROS origin。请提供一个简单的示例-
