使用 PHP Telegram Bot InputMediaPhoto 方法

Question

我试图用我的 Telegram 机器人将一些图像发送到一条消息中。我使用InputMediaPhoto方法发送，但不幸的是不起作用。这是我的代码：$url = "https://api.telegram.org/bot" . "TOKEN" . "/InputMediaPhoto";$postContent = [    'chat_id' => $GLOBALS['chatId'],    'media' => [        ['type'=>'photo' ,'media' => 'http://www.alcan5000.com/JPG/64Caliente.jpg'], //Just for test        ['type' => 'photo' ,'media' => 'http://www.alcan5000.com/JPG/64Caliente.jpg'],        ['type' => 'photo' ,'media' => 'http://www.alcan5000.com/JPG/64Caliente.jpg']    ]];post($url, $postContent);function post($url, $postContent){    $curl = curl_init();    curl_setopt($curl, CURLOPT_URL, $url);    curl_setopt($curl, CURLOPT_POSTFIELDS, $postContent);    curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);    $result = curl_exec($curl);    curl_close($curl);    return $result;}
