我有一个带有以下代码的自定义插件

add_action( \'init\', \'my_script_enqueuer\' );

function my_script_enqueuer() {
   wp_register_script( "gift_card_redeem", WP_PLUGIN_URL.\'/plugin-folder/gift_card_redeem.js\', array(\'jquery\') );
   wp_localize_script( \'gift_card_redeem\', \'myAjax\', array( \'ajaxurl\' => admin_url( \'admin-ajax.php\' )));        

   wp_enqueue_script( \'jquery\' );
   wp_enqueue_script( \'gift_card_redeem\' );

}

add_action("wp_ajax_gift_card_redeem", "gift_card_redeem");

function gift_card_redeem(){

  if(!empty($_SERVER[\'HTTP_X_REQUESTED_WITH\']) && strtolower($_SERVER[\'HTTP_X_REQUESTED_WITH\']) == \'xmlhttprequest\') {
    error_log("test !empty");
    $result[\'type\'] = "success";
    $result = json_encode($result);
    echo $result;
  }
  else {
    error_log("test else");
      header("Location: ".$_SERVER["HTTP_REFERER"]);
  }

  die();
}

插件中有一个js文件，名为gift\\u card\\u redeme。js公司

jQuery(document).ready(function () {
  jQuery(".redeem_gift_card").click(function (e) {
    e.preventDefault();

    jQuery.ajax({
      type: "post",
      dataType: "json",
      url: myAjax.ajaxurl,
      data: { action: "redeem_gift_card" },
      success: function (response) {
        if (response.type == "success") {
          jQuery("#test").html(response);
        } else {
          alert("something broke");
        }
      },
    });
  });
});

表单签出页面上的php和html如下

<?php
    $link = admin_url(\'admin-ajax.php?action=gift_card_redeem\');
        echo \'<a class="redeem_gift_card" href="\' . $link . \'" >test</a>\';
    ?> 

    <h1 id="test">Test</h1>

我收到一个400错误的管理ajax请求错误。php和我不太清楚为什么。任何帮助都将不胜感激。

谢谢
