一、js：

  1. 要點：
    js通過ajax傳送header資訊php接收
  2. 完整程式碼： 
    <!DOCTYPE html>
<html lang="en">
    <head>
        <meta charset="UTF-8">
        <title>Document</title>
        <script src="jquery.min.js"></script>
    </head>
    <body>
            <script>
                    $.ajax({
                            `url`:`http://localhost/index.php`,
                            `data`:{`sex`:`male`},
                            `beforeSend`:function(xhr){
                                xhr.setRequestHeader(`name`,`lee`);
                                xhr.setRequestHeader(`sex`,`male`);
                                xhr.setRequestHeader(`height`,`168`);
                            },
                            `success`:function(data){
                                console.log(data);
                            }
                        });
            </script>
    </body>
</html>

    二、php：

  3. 要點：
    js通過ajax傳送header資訊php接收
  4. 完整程式碼： 
    <?php
        header(`Access-Control-Allow-Origin:*`);
        header(`Access-Control-Allow-Credentials: true`);
        header(`Access-Control-Allow-Methods:GET,PUT,POST,DELETE,OPTIONS`);

        $header = apache_request_headers();
        var_Dump($header);exit;
