我正在开发一个WordPress插件来进行短代码和查看PowerBI报告。我有json文件中的所有数据。我已经测试了文件和功能代码。WordPress代码没有问题。下面的AJAX中有一些错误，在控制台中显示以下错误。

POST: http://localhost/xxx/wp-admin/admin-ajax.php [HTTP/1.1 400 Bad Request 418ms]

以下是jQuery代码：

jQuery(document).ready( function(){         
    jQuery(\'.subjectdiv\').on(\'click\', \'a.acaret\', function(e) { 
        e.preventDefault();
        var rml_post_id = jQuery(this).attr( \'mydata\' );    

        jQuery.ajax({
            url : mypowerbi_ajax.ajax_url,
            type : \'post\',
            data : {
                action : \'powerbi_manager_ajax\',
                _ajax_nonce: mypowerbi_ajax.check_nonce,
                post_id : rml_post_id
            },
            success : function( response ) {
              jQuery(\'.powerbitabwindow\').html(response);
            }
        });
    });     
});

下面是函数及其代码

function fn_powerbi_manager($atts) {
  wp_enqueue_style(\'bootstrapstyle\', plugins_url(\'/powerbi_manager/assets/css/bootstrap.min.css\'), __FILE__);
  wp_enqueue_script(\'bootstrapscript\', plugins_url(\'/powerbi_manager/assets/js/bootstrap.min.js\'), __FILE__);
  wp_enqueue_style(\'powerbistyle\', plugins_url(\'/powerbi_manager/assets/css/style.css\'), __FILE__);
  wp_enqueue_script(\'jqueryscript\', plugins_url(\'/powerbi_manager/assets/js/jquery.min-v3.5.1.js\'), __FILE__);
  wp_enqueue_script(\'powerbiscript\', plugins_url(\'/powerbi_manager/assets/js/scripts.js\'), __FILE__);

  add_action(\'wp_enqueue_scripts\', \'bootstrapstyle\');
  add_action(\'wp_enqueue_scripts\', \'bootstrapscript\');
  add_action(\'wp_enqueue_scripts\', \'powerbistyle\');
  add_action(\'wp_enqueue_scripts\', \'jqueryscript\');
  add_action(\'wp_enqueue_scripts\', \'powerbiscript\');
  
  wp_register_script( \'myajax-script\', plugins_url( \'assets/js/ajaxcall.js\', __FILE__ ), array(\'jquery\'), null, true );
  wp_enqueue_script( \'myajax-script\' );
  wp_localize_script( \'myajax-script\', \'mypowerbi_ajax\', array( \'ajax_url\' => admin_url(\'admin-ajax.php\'), \'check_nonce\' => wp_create_nonce(\'powerbi_manager_nonce\') ));

   require_once plugin_dir_path( __FILE__).\'templates/frontend-page.php\';
}
function my_powerbi_manager_ajax() 
{
    check_ajax_referer( \'powerbi_manager_nonce\' );
     $rml_post_id = $_POST[\'post_id\'];
     $json = file_get_contents(plugins_url(\'/powerbi_manager/json/powerbimanager.json\'));
     $decoded_json = json_decode($json, true);
     $shortcodedata = array();
     foreach ($decoded_json as $rkey => $jsondata){
       if ($jsondata[\'visualidentifier\'] == $rml_post_id){

           $shortcodedata[] = $jsondata[\'shortcode\'];
       } 
    }
     echo do_shortcode($shortcodedata[0]);
}

if (function_exists(\'my_powerbi_manager_ajax\'))
{
  add_action( \'wp_ajax_powerbi_manager_ajax\', \'my_powerbi_manager_ajax\' ); 
}
add_shortcode(\'powerbi-manager\', \'fn_powerbi_manager\');

谁能找出错误或给我建议？提前感谢

add_action( \'wp_ajax_nopriv_powerbi_manager_ajax\', \'my_powerbi_manager_ajax\' );
