WordPress中的Ajax返回400错误请求，但不确定如何进一步调试 _Ajax

我一直试图使用Ajax将页面的数据(或其他任何东西)输出到div中。数据基于页面上的列表。尽管调用Ajax请求的jQuery函数似乎可以正常工作, 但是从Ajax调用在控制台上却收到了400个错误的请求。如何调试它, 因为我无法从Ajax回调函数中获取任何console.log消息
我有一个wordpress文件, 该文件输出产品类别的列表以及单击列出的类别之一时触发的一些jQuery。该jQuery具有Ajax发布函数来调用我的入队和本地化函数。该函数似乎没有任何作用, 即使是简单的console.log, ajax调用的：error也表明该错误是一个400错误的请求。使用WPEngine密码保护的登台站点, 可能会有所作为。

我一直在控制台中收到错误400错误的错误请求, 但在如何进一步调试方面感到困惑, 因为当我回声, 警报或console.log时, 没有出现回调函数的输出。
#1只是想通了。
我对jQuery.post进行了如下代码更改：原始-无法正常工作：
jQuery.post({url：ajax.url, action：’ show_products’ , term_id：term_id_clicked, success：function(data){
转换为这种格式, 现在返回200代码：
