Question

我正在使用PHP开发一个FB messenger机器人，但我有一个关于按钮点击事件的查询，如何触发＆amp;打电话给新卡/文字。任何人都可以用PHP解释一下按钮回发的例子吗？

这是你的意思吗？

$data = json_decode(file_get_contents("php://input"), true, 512, JSON_BIGINT_AS_STRING);

         else if (!empty($message['postback'])) {
             $command = $message['postback']['payload'];
        }
    }

使用PHP，您将发送相信您的FB机器人是人类的请求。

通常它是生成这些查询的javascript。您必须发送相同的内容。

您可以使用CURL库和chrome devtools＆amp;网络标签。
