我正在尝试创建一个 Wordpress 插件,它将接收一个简单的 AJAX 请求,并且目前只发布它的正文。我的代码是:

文件/wp-content/plugins/prova/prova.php:

<?php

/**
 * Plugin Name:       My Basics Plugin
 * Plugin URI:        https://example.com/plugins/the-basics/
 * Description:       Handle the basics with this plugin.
 */

function risposta_mia_azione() {
  $param = $_POST["param"];
  echo $param;
  wp_die();
}

/**
 * Register the "book" custom post type
 */
function pluginprefix_setup_post_type() {
} 
add_action( 'init', 'pluginprefix_setup_post_type' );

/**
* Activate the plugin.
*/
function pluginprefix_activate() { 
}
register_activation_hook( __FILE__, 'pluginprefix_activate' );

/**
 * Deactivation hook.
 */
function pluginprefix_deactivate() {
}
register_deactivation_hook( __FILE__, 'pluginprefix_deactivate' );

/**
 * Uninstallation hook.
 */
function pluginprefix_uninstall() {

}
register_uninstall_hook( __FILE__, 'pluginprefix_uninstall' );


add_action("wp_ajax_nopriv_mia_azione", "risposta_mia_azione");

?>

我的 Wordpress 安装的根目录是http://123.compute.amazonaws.com/wordpress/. 现在,如果我在该安装的页面中打开开发工具控制台并粘贴以下 jQuery ajax 调用,我将得到POST http://132.compute.amazonaws.com/wordpress/wp-admin/admin-ajax.php 400 (Bad Request)

(function( $ ) {
$.ajax({
    url : 'http://123.compute.amazonaws.com/wordpress/wp-admin/admin-ajax.php',
    data : {"action" : "mia_azione", "param" : "ciao"},
    method : 'POST',
    success : function( response ){ console.log(response) },
    error : function(error){ console.log(error) }
  })
})(jQuery)

多年来我没有接触过 Wordpress,而且我对 Wordpress 的底层非常不熟悉,从我在类似问题中读到的内容来看,这通常是请求格式不正确的情况,但我真的看不到我的错误。例如,像这样的调用:

ajaxresponse = await fetch("http://ec2-3-129-17-101.us-east-2.compute.amazonaws.com/wordpress/wp-admin/admin-ajax.php", {
    method: 'POST', mode: 'no-cors',
    headers: {
      'Content-Type': 'application/json'
      // 'Content-Type': 'application/x-www-form-urlencoded',
    },
    body: JSON.stringify({action: "mia_azione", param: "ciao"}) 
  });

会给我这样的回应:

body: ReadableStream
bodyUsed: true
headers: Headers {}
ok: false
redirected: false
status: 400
statusText: "Bad Request"
type: "basic"
url: "http://123.compute.amazonaws.com/wordpress/w

有人可以帮助我吗?

编辑:正如响应所指出的,我使用了错误的功能 - 我需要的是:https ://developer.wordpress.org/rest-api/extending-the-rest-api/adding-custom-endpoints/

也许你需要这样的东西:

function my_enqueue() {
      wp_enqueue_script( 'ajax-script', get_template_directory_uri() . '/js/my-ajax-script.js', array('jquery') );
      wp_localize_script( 'ajax-script', 'my_ajax_object', array( 'ajax_url' => admin_url( 'admin-ajax.php' ) ) );
 }
 add_action( 'wp_enqueue_scripts', 'my_enqueue' );
