【開発者ブログ】PHPでLINE Messaging APIを使ってメッセージ送信してみた

composer require linecorp/line-bot-sdk

<?php
require_once __DIR__ . "/vendor/autoload.php";

use LINE\Clients\MessagingApi\Api\MessagingApiApi;
use LINE\Clients\MessagingApi\Configuration;
use LINE\Clients\MessagingApi\Model\PushMessageRequest;
use LINE\Clients\MessagingApi\Model\TextMessage;
use GuzzleHttp\Client;

$accessToken = 'YOUR_CHANNEL_ACCESS_TOKEN'; //チャネルアクセストークン
$userId = 'Uxxxxxxxxxxxxxxxxxxxx'; //ユーザーID

// --- Guzzle クライアントに Authorization ヘッダーを明示的にセット ---
$httpClient = new Client([
    'headers' => [
        'Authorization' => 'Bearer ' . $accessToken,
        'Content-Type' => 'application/json',
    ],
]);

// --- Configuration オブジェクト（空でも可） ---
$config = new Configuration();

// --- MessagingApiApi を Guzzle + Configuration で初期化 ---
$client = new MessagingApiApi($httpClient, $config);

// --- メッセージ作成 ---
$textMessage = new TextMessage([
    'type' => 'text',
    'text' => 'テスト送信!',
]);

$request = new PushMessageRequest([
    'to' => $userId,
    'messages' => [$textMessage],
]);

try {
    $response = $client->pushMessage($request);
    var_dump($response);
    echo "送信成功！";
} catch (\LINE\Clients\MessagingApi\ApiException $e) {
    echo "API Error: " . $e->getMessage();
    echo "\nResponse Body: " . $e->getResponseBody();
}
