如何在移动端获取wordpress woocommerce的有效期？

Question

我有wordpress woocommerce网站。我正在尝试从这个网站获取移动后端的数据。当用户通过后端登录时，我想从我的后端从网站获得过期日期。但是我得到了一些错误。

我想知道的是，为了运行wc_memberships_get_user_memberships()函数，我应该包含哪些woocommerce文件。

这是我的后端源代码。

<?php
// required headers
header("Access-Control-Allow-Origin: *");
header("Content-Type: application/json; charset=UTF-8");

// include database and object files
include_once 'db_connect.php';
include_once '../wp-content/plugins/woocommerce/includes/class_woocommerce.php';
include_once '../wp-content/plugins/woocommerce-memberships/woocommerce-memberships.php';
include_once '../wp-content/plugins/woocommerce-memberships/includes/functions/wc-memberships-functions-user-memberships.php';

class FetchData {

    public function logIn() {
        if( isset($_POST['user_name']) && isset($_POST['password']) ){

            $password = $_POST['password'];

            $sql = "SELECT * FROM `wprl_users` WHERE `user_email` = '".$_POST['user_name']."' limit 1";
            $query = mysqli_query(DBOpen(), $sql);
            $user_info = mysqli_fetch_assoc($query);            

            if (count($user_info) > 0) {

                require_once( '../wp-includes/class-phpass.php' );
                $hasher = new PasswordHash(8, TRUE);

                $pass_match = $hasher->CheckPassword( $password, $user_info['user_pass'] );

                if($pass_match == TRUE) {
                    // Get memberships for the current user.
                    $memberships = wc_memberships_get_user_memberships($user_info['ID']);

                    // Verify that they have some memberships.
                    if ( $memberships ) {
                            foreach( $memberships as $memberships ) {
                                // Print the expiration date in mysql format.
                                $end_date = $membership->get_end_date();
                            }
                    }
                    echo json_encode(array('result'=>'success', 'member_name'=>$user_info['display_name'], 'member_num'=>
                                            $user_info['ID'], 'expiry_date'=>$end_date));
                }
                else {
                    echo json_encode(array('result'=>'failed', 'message'=>'User name or password incorrect!'));
                }
            }
            else {                                              
                echo json_encode(array('result'=>'failed', 'message'=>'User name or password incorrect!'));
            }   
        }
        else {
            echo json_encode(array('result'=>'failed', 'message'=>'Wrong parameter'));
        }
    }
}

$option = new Fetchdata();

$options = (isset($_POST['options'])) ? $_POST['options'] : 1;

    switch ($options){ 
        case "login":
            $option->logIn();
            break;
    }

?>

Wordpress有一种特定的方式来引导他们的代码，连接到数据库，初始化插件等等。在你这样做的时候，你尝试手动包含这些文件，即使你是手动使用check pass。这就是https://codex.wordpress.org/Function_Reference/wp_check_password本身。所以你所做的有点不符合他们的模式。如果你真的想这样做，你可以从/index.php回溯引导代码

然而，对你来说最好的解决方案是你应该创建一个wordpress插件。你可以按照这个指南https://codex.wordpress.org/Writing_a_Plugin

或https://www.smashingmagazine.com/2011/09/how-to-create-a-wordpress-plugin/
