Question

我正在使用php开发一个Facebook Messenger机器人我想按正式文档中的说明设置问候语文本：Greeting text

curl -X POST -H "Content-Type: application/json" -d '{
  "setting_type":"greeting",
  "greeting":{
    "text":"New message."
  }
}' "https://graph.facebook.com/v2.6/me/thread_settings?access_token=my_token"

上面的命令有效，我得到了：

{"result":"Successfully updated greeting"}

我写了相应的PHP代码利用Guzzle：

$data = '{"setting_type":"greeting","greeting":{"text":"New message."}}';
$client = new \GuzzleHttp\Client();
$response = $client->post(
    'https://graph.facebook.com/v2.6/me/messages?access_token=' . $my_token,
       [
            'headers' => ['Content-Type' => 'application/json'],
            'body' => $data,
            'debug' => true
       ]
);

但它不起作用..请注意上面的php代码可以正常使用Send API参考的其他方法，例如Text message。

我做错了什么？我会根据要求提供任何其他信息。感谢。
