PHP 设置跨域 Access-Control-Allow-Origin 绑定多个域名

Question

Access-Control-Allow-Origin 一般情况下只能绑定一个值，当然 * 可以任意，但是不推荐，下面介绍如果绑定多个值。

$origins = ['http://127.0.0.1:7001', 'https://www.wenjiangs.com'];
$origin = isset($_SERVER['HTTP_ORIGIN']) ? $_SERVER['HTTP_ORIGIN'] : '';
if (in_array($origin, $origins)) {
    header("Access-Control-Allow-Origin: " . $origin);
    header('Access-Control-Allow-Credentials: true');
    header("Access-Control-Allow-Headers: Origin, X-Requested-With, Content-Type, Accept");
}
