gettint error 400 with AJAX

你好，我得到错误400。这是我的PHP和JS文件路径。PHP

add_action("wp_enqueue_scripts", "js_enqueue_search");
function js_enqueue_search(){
    wp_register_script("search", get_stylesheet_directory_uri() . "/js/search.js", "", wp_get_theme()->get("Version"), true);
    wp_enqueue_script("search");
    wp_localize_script("search","search_x", array("ajaxurl" => admin_url("admin-ajax.php")));
}

add_action("wp_ajax_nopriv_search_data", "search_data");
add_action("wp_ajax_search_data", "search_data");
function search_data(){
    echo "test";
    wp_die();
}

JS公司

let ajax = new XMLHttpRequest();
ajax.open("GET", search_x.ajaxurl, true);
ajax.send();

ajax.onreadystatechange = function() {
  if (this.readyState == 4 && this.status == 200) {
    console.log(this.ajax);
  }
};

let ajax = new XMLHttpRequest(); ajax.open("GET", search_x.ajaxurl + \'?action=search_data\', true); ajax.send(); ajax.onreadystatechange = function() { if (this.readyState == 4 && this.status == 200) { console.log(this.ajax); } };

从unctions.php中的URL拉取GET参数

我跟踪了WordPress, 但是我的functions.php 文件仍无法获取token (abcd) URL中的变量：https://example.com/reset-password/?token=abcd我的职能。php文件包括以下内容：function add_query_vars_filter( $vars ) { $vars[] = \"token\"; return $vars; } add_filter( \'query_vars\', \'ad
