WordPress Customize Plugin – 微信客製外掛-Token認證

建立微信 ( Weixin ) token verified 的回覆頁面, 要先安裝 plugin: wp-router
  1. 建立轉向的網址
  2. 設定 function 要處理的程式檔
  3. 微信 token 驗證的程式處理
  • 建立轉向的網址: wpwxtoken & 對應處理的 function: wpwxtoken_route_callback
add_action( 'wp_router_generate_routes', 'add_wpwxtoken_route', 20 );
function add_wpwxtoken_route( $router ) { 
    $route_args = array(
                        'path' => '^wpwxtoken',
                        'query_vars' => array( ),
                        'page_callback' => 'wpwxtoken_route_callback',
                        'page_arguments' => array( ),
                        'access_callback' => true,
                        'title' => __( 'weixin token Route' ),
                        'template' => array(
                                    'page.php',
                                dirname( __FILE__ ) . '/page.php'
                        )
                );

    $router->add_route( 'wpwxtoken-route-id', $route_args );
}
  • 設定 function: wpwxtoken_route_callback 要處理的程式檔
// 轉到這個頁面: /admin/wx-token.php 
function wpwxtoken_route_callback( ) {
    include (WPWX_PLUGIN_DIR . '/admin/wx-token.php');
}
  • wx-token.php : 微信 token 驗證的程式處理
<?php
/**
 * 驗證微信的 token
 */
$path = $_SERVER['DOCUMENT_ROOT'];
include_once $path . '/wp-config.php';
include_once $path . '/wp-load.php';
include_once $path . '/wp-includes/wp-db.php';
include_once $path . '/wp-includes/pluggable.php';

// 由微信平台自已設定的 token 值
$token     = get_option( 'wpwx_Token');

// 由微信平台 post 送來的參數
$signature =isset($_GET["signature"])?$_GET["signature"]:'';
$timestamp =isset($_GET["timestamp"])?$_GET["timestamp"]:'';
$nonce = isset($_GET["nonce"])?$_GET["nonce"]:'';
$echostr   = isset($_GET['echostr'])?$_GET["echostr"]:'';
$post_data = "{'signature':$signature, 'timestamp:', $timestamp, 'nonce:': $nonce, 'echostr': $echostr }";
//組合參數作 shal 運算
$tmpArr = array($token, $timestamp, $nonce);
sort($tmpArr,SORT_STRING);
$tmpStr = implode( $tmpArr );
$tmpStr = sha1( $tmpStr );

//驗證 
if( $tmpStr == $signature ){
  echo $echostr;  
}else{  
  //wp_send_json_error( array('code' => 500, 'data' => $post_data, 'msg' => '錯誤的請求')  );
  wp_redirect(home_url());
}
exit();
