Question

我是wordpress插件的新手。我有问题，访问wordpress插件的正确方法是什么？让我们说在我的插件中，我需要创建端点来处理不同的回调。我尝试了很多谷歌搜索结果，但没有工作。我不知道出了什么问题。请帮忙。

<?php
/*
Plugin Name: MyPlugin
Description: MyPlugin
Author: Myself
Author URI:
Version: 1.0
License:
License URI:
*/

class MyPlugin {

  private static $instance;

  public static function getInstance() {
    if(self::$instance == NULL) {
      self::$instance = new self();
    }
    return self::$instance;
  }

  private function __construct() {
    add_action( 'init', array($this, 'set_endpoint' ) );
  }

  function set_endpoint() {
     add_rewrite_rule( 'callback/$', plugin_dir_url(__FILE__) . 'callback.php', 'top' );
  }

  static function activate() {
    global $wp_rewrite;
    $wp_rewrite->flush_rules(true);
  }
}

MyPlugin::getInstance();
register_deactivation_hook(__FILE__,'flush_rewrite_rules');
register_activation_hook(__FILE__,'MyPlugin::activate');

callback.php

<?php  echo '<h1> Hello </h1>'; ?>

Answer 1

好的，我找到了答案。

<?php

class MyPlugin {

  private static $instance;

  public static function getInstance() {
    if(self::$instance == NULL) {
      self::$instance = new self();
    }
    return self::$instance;
  }

  private function __construct() {
    add_action( 'init', array($this,'callback_init_internal' ) );
    add_filter( 'query_vars', array($this,'callback_query_vars' ) );
    add_action( 'parse_request', array($this,'callback_request' ) );
  }

  function callback_init_internal()
  {
      add_rewrite_rule( 'callback.php', plugin_dir_url(__FILE__) . 'callback.php?callback=$matches[1]', 'top' );
  }

  function callback_query_vars( $query_vars )
  {
      $query_vars[] = 'callback';
      return $query_vars;
  }

  function callback_request( &$wp )
  {
      if ( array_key_exists( 'callback', $wp->query_vars ) ) {
        header('content-type: text/html; charset=utf-8');
        $value = $wp->query_vars['callback'];
        if ( $value === 'return' ) {
            echo 'Return URL';
        } else if ( $value === 'notify' ) {
            echo 'Notify URL';
        } else {
            echo '404 Invalid endpoint';
        }
        exit();
      }
      return;
  }

  static function activate() {
    global $wp_rewrite;
    flush_rewrite_rules();
    $wp_rewrite->flush_rules(true);
  }
}


MyPlugin::getInstance();

register_deactivation_hook(__FILE__,'flush_rewrite_rules');
register_activation_hook(__FILE__,'MyPlugin::activate');

从浏览器访问网址

接受的参数=通知或返回

http://localhost:8080/wordpress/callback.php?callback=notify 通知网址

http://localhost:8080/wordpress/callback.php?callback=something 404无效端点
