line-bot-sdk-phpとreplyToken

LINE Messaging APIを使用した開発をやります。
$ php composer.phar require linecorp/line-bot-sdk
$ php composer.phar require guzzlehttp/guzzle

こちらでは上手くいかない

require("vendor/autoload.php");

use LINE\LINEBot\Constant\HTTPHeader;
use LINE\LINEBot\HTTPClient\CurlHTTPClient;
use LINE\LINEBot;

$channel_access_token = 'xxxx';
$channel_secret = 'xxxx';

$http_client = new CurlHTTPClient($channel_access_token);
$bot = new LINEBot($http_client, ['channelSecret' => $channel_secret]);
$signature = $_SERVER['HTTP_' . HTTPHeader::LINE_SIGNATURE];
$http_request_body = file_get_contents('php://input');
$events = $bot->parseEventRequest($http_request_body, $signature);
$event = $events[0];

$reply_token = $event->getReplyToken();
$reply_text = $event->getText();
$bot->replyText($reply_token, $reply_text);

Githubを見ながら少し内容を変更します。SDKのバージョンによってライブラリのclass構成が変わっているようです。

replyTokenは、{“events”}[0]に入っている。line-bot-sdk-phpのsampleを見ても全然わからなかったので、凄い時間がかったw

ini_set("display_errors", 1);
error_reporting(E_ALL);
require("vendor/autoload.php");

$jsonString = file_get_contents('php://input'); error_log($jsonString); 
$jsonObj = json_decode($jsonString); $message = $jsonObj->{"events"}[0]->{"message"}; 
$replyToken = $jsonObj->{"events"}[0]->{"replyToken"};

$client = new \GuzzleHttp\Client();
$config = new \LINE\Clients\MessagingApi\Configuration();
$config->setAccessToken('');
$messagingApi = new \LINE\Clients\MessagingApi\Api\MessagingApiApi(
  client: $client,
  config: $config,
);

$message = new \LINE\Clients\MessagingApi\Model\TextMessage(['type' => 'text','text' => $message->{"text"}]);
$request = new \LINE\Clients\MessagingApi\Model\ReplyMessageRequest([
    'replyToken' => $replyToken,
    'messages' => [$message],
]);
$response = $messagingApi->replyMessage($request);
