我正在使用发件人。net获取电子邮件订阅列表。这个网站给了我一些信息，可以将用户的电子邮件添加到订阅列表中。我想使用WordPress ajax来实现这一点。但它返回错误400错误请求。我的代码是：

文件ajax新闻脚本。js公司：

    jQuery(document).ready(function($){

    // Perform AJAX send news on form submit
    $(\'form#fnews\').on(\'submit\', function(e){

        $(\'form#fnews #fsubmit\').text(ajax_news_object.loadingmessage);
        $.ajax({
            type: \'POST\',
            dataType: \'json\',
            url: ajax_news_object.ajaxurl,
            data: { 
                \'action\': \'ajaxnews\', //calls wp_ajax_nopriv_ajaxnews
                \'email\': $(\'form#fnews #femail\').val(),  
                \'security\': $(\'form#fnews #security\').val() },

            success: function(data){
                $(\'form#fnews #fsubmit\').text(data.message);
              }
            });
            e.preventDefault();
        });
    });
