在自定义插件中设置wp_Schedule_Event

我正在使用WordPress 4.9.6 我正在尝试创建一个插件，从外部API提取数据。

请参见以下我的当前代码：

myPlugin.php

<?php
/**
Plugin Name: myPlugin
description: Get Data via APIs
Version: 1.0
Author: Batman
License: GPLv2 or later
Text Domain: myPlugin
*/

if ( ! defined( \'ABSPATH\' ) ) {
    exit;
}

require_once \'vendor/autoload.php\';

class My_Plugin {

      /**
     * Constructor.
     */
    public function __construct() {
        define( \'MyPlugin_FILE\', __FILE__ );
        define( \'MyPlugin_DIR\', trailingslashit( dirname( __FILE__ ) ) );
        define( \'MyPlugin_VERSION\', \'0.0.1\' );
        register_activation_hook( basename( MyPlugin_DIR ) . \'/\' . basename( MyPlugin_FILE ), array( $this, \'activate\' ) );
        add_action( \'plugins_loaded\', array( $this, \'includes\' ) );
        add_action( \'init\', array( $this, \'maybe_update\' ) );
    }

    public function activate() {
        $this->includes();
        flush_rewrite_rules();
    }

    public function includes() {
        include_once( MyPlugin_DIR . \'includes/WhatToMineAPI.php\' );
    }

    /**
     * Maybe update MyPlugin.
     */
    public function maybe_update() {
        $version = get_option( \'MyPlugin_version\', 0 );
        if ( version_compare( $version, MyPlugin_VERSION, \'<\' ) ) {
            $this->create_tables();
            update_option( \'MyPlugin_version\', MyPlugin_VERSION );
        }
    }
}
new My_Plugin();

WhatToMineAPI.php

<?php

use GuzzleHttp\\Client;

class WhatToMineAPI {

    /**
     * Constructor.
     */
    public function __construct() {
        add_action( \'setupCronJob_whatToMine\', \'setupCronJob\');
        add_action( \'update_whatToMine_api\', \'updateWhatToMineAPI\');

        // variables
        $whatToMineURL = "http://whattomine.com/coins.json";
    }

    public function setupCronJob() {
        //Use wp_next_scheduled to check if the event is already scheduled
        $timestamp = wp_next_scheduled( \'update_whatToMine_api\' );

        //If $timestamp == false schedule daily backups since it hasn\'t been done previously
        if( $timestamp == false ){
            //Schedule the event for right now, then to repeat daily using the hook \'update_whatToMine_api\'
            wp_schedule_event( time(), \'twicedaily\', \'update_whatToMine_api\' );
        }
    }

    public function updateWhatToMineAPI() {

        $client = new GuzzleHttp\\Client();

        $response = $client->request(\'GET\', $whatToMineURL);

    }


}
new WhatToMineAPI();

我已经安装了插件WP-Control 了解我正在运行的cron作业的概况。然而，我的cron工作update_whatToMine_api 在表中找不到？

我当前的cron设置是否错误？

感谢您的回复！

register_activation_hook( __FILE__, array(My_Plugin::class, \'activate\') ); register_deactivation_hook( __FILE__, array(My_Plugin::class, \'deactivate\') ); class MyPlugin { public static function activate() { WhatToMineAPI::setupCronJob(); } public static function deactivate() { WhatToMineAPI::unsetCronJob(); } // your other methods }

class WhatToMineAPI { const CRON_HOOK = \'update_whatToMine_api\'; public static function setupCronJob() { //Use wp_next_scheduled to check if the event is already scheduled $timestamp = wp_next_scheduled( self::CRON_HOOK ); //If $timestamp === false schedule daily backups since it hasn\'t been done previously if( $timestamp === false ){ //Schedule the event for right now, then to repeat daily using the hook \'update_whatToMine_api\' wp_schedule_event( time(), \'twicedaily\', self::CRON_HOOK ); } } public static function unsetCronJob() { // Get the timestamp for the next event. $timestamp = wp_next_scheduled( self::CRON_HOOK ); wp_unschedule_event( $timestamp, self::CRON_HOOK ); } public function __construct() { add_action(self::CRON_HOOK, array($this, \'updateWhatToMineAPI\')); } public function updateWhatToMineAPI() { $client = new GuzzleHttp\\Client(); $response = $client->request(\'GET\', $whatToMineURL); } }

如何强制admin-ajax.php文件通过HTTPS加载？

我最近有一个网站100%支持HTTPS。前端和后端的所有资产都通过HTTPS成功调用，除了admin ajax。php。这会导致任何依赖于文件的功能失败，包括但不限于CF7、Elementor和其他使用AJAX提交的表单等。我得到的错误，你可以在截图中看到是“混合内容：页面位于”https://toursoft.co/contact-us/\' 已通过HTTPS加载，但请求了不安全的XMLHttpRequest终结点\'http://toursoft.co/wp-admin/admin-ajax.php\
