php - Facebook 聊天机器人以 "Action Unsuccessful"错误响应持久菜单回发

Question

直到几天前，我的 facebook Chatbot 的持久菜单都运行良好，当我点击一个持久菜单项时，每隔几次尝试就会出现一个弹出错误:行动不成功将您的消息传递给机器人时出错。请稍后再试。

这种情况偶尔会发生，我检查过当这种情况发生时我的 PHP 代码端没有收到来自 facebook 的任何回传。如果没有错误，回发工作正常。还有其他人收到此错误吗？

我的永久菜单是这样设置的:

//-----------Persistent Menu
$url = 'https://graph.facebook.com/v2.6/me/messenger_profile?access_token='.$access_token;
$ch = curl_init($url); 

$jsonData = '{
  "persistent_menu":[
    {
      "locale":"default",
      "composer_input_disabled": false,
      "call_to_actions":[
            {
              "title":"View in Chinese",
              "type":"postback",
              "payload":"mainMenu"
            },
            {
              "title":"View in English",
              "type":"postback",
              "payload":"mainMenuEN"
            }


      ]
    },
        {
      "locale":"zh_TW",
      "composer_input_disabled": false,
      "call_to_actions":[
            {
              "title":"View in Chinese",
              "type":"postback",
              "payload":"mainMenu"
            },
            {
              "title":"View in English",
              "type":"postback",
              "payload":"mainMenuEN"
            }

      ]
    },      
        {
      "locale":"en_US",
      "composer_input_disabled": false,
      "call_to_actions":[
            {
              "title":"View in Chinese",
              "type":"postback",
              "payload":"mainMenu"
            },
            {
              "title":"View in English",
              "type":"postback",
              "payload":"mainMenuEN"
            }

      ]
    }
  ]
}';
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $jsonData);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json'));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$result = curl_exec($ch);

我遇到了同样的问题。它已通过以下更改修复:

App settings -> [Products] Messenger -> Settings -> Webhooks -> Edit events -> Add messaging_postbacks

您可能忘记添加事件，并且不允许 FB 向服务器发送任何按钮的回发/负载。

彻底检查按钮的类型是否正确指定为以下之一:web_url 或小写的 postback。

还请记住，根据 FB Developers Doc，永久菜单需要 pages_messaging 权限
