類似主動傳訊息給 user，不過在傳訊類型定義為 multicast。要傳訊的目標對象是多位 user，所以 UserId 要存在陣列中。
<php?
date_default_timezone_set('Asia/Taipei');
$sRootDir = $_SERVER['DOCUMENT_ROOT'];
$channelAccessToken = '您的 channel Access Token';
$bodyMsg = file_get_contents('php://input');
// LINE 不會幫我們記錄, 所以要自己寫 log
// 這段不是必要, 只是方便自己除錯
$sLogfile = 'log_'.date('Ymd').'.log'; // 指定 log 檔名, 一天一個檔, 檔名格式為: log_yyyymmdd.log
$fp = fopen($sLogfile, "a+");
fwrite($fp , print_r(date('Y-m-d H:i:s').', Recive: '.$bodyMsg."\n", true));
fclose($fp);
...
...
// 取得 user id, 管道有很多, 此處不贅述
$arrUserId = ['...','...', ...]; ← 要推播的目標 UserId 存入陣列
$payload = [ 'to' => $arrUserId,
'messages' => [
['type' => 'text',
'text' => '恭喜! 您中了特獎!',
]
]
];
SendMsg($payload);
// 傳送訊息給指定使用者
function SendMsg($payload) {
$ch = curl_init();
// curl_setopt($ch, CURLOPT_URL, 'https://api.line.me/v2/bot/message/push');
↓ 注意這裡要改成 multicast
curl_setopt($ch, CURLOPT_URL, 'https://api.line.me/v2/bot/message/multicast');
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'POST');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($payload));
curl_setopt($ch, CURLOPT_HTTPHEADER, [ 'Content-Type: application/json',
'Authorization: Bearer ' . $GLOBALS['channelAccessToken']
]);
$result = curl_exec($ch);
curl_close($ch);
// 寫 log
$sLogfile = 'log_'.date('Ymd').'.log';
$fp = fopen($sLogfile, "a+");
fwrite($fp , print_r(date('Y-m-d H:i:s').', send message result: '.$result."\n", true));
fclose($fp);
}
?>
