摘要：如果机器人收到币，大于零如果机器人支付币给用户，接收到的消息是一样的，唯一不同的是是一个负数最后一步，调用将币还给用户完整的代码在这儿

在上一篇教程中, 我们创建了自动回复消息的机器人,当用户发送消息"Hello,World!"时，机器人会自动回复同一条消息!

按本篇教程后学习后完成后，你的机器人将会接受用户发送过来的加密货币，然后立即转回用户。下面是全部源代码，创建一个app.php试一下吧！

你好，我的币!

在工程目录下，执行 php app.php

php app.php

wenewzha:mixin_labs-php-bot wenewzhang$ php app.php
a1ce2967-a534-417d-bf12-c86571e4eefa{"id":"12c7a470-d6a4-403d-94e8-e6f8ae833971","action":"LIST_PENDING_MESSAGES"}stdClass Object
(
    [id] => 12c7a470-d6a4-403d-94e8-e6f8ae833971
    [action] => LIST_PENDING_MESSAGES
)

如果控制台出现 "LIST_PENDING_MESSAGES"字样, 连接到mixin.one成功了，正在侦听用户发送消息给它!

按帮助来操作,发送消息得到相应的支付提示

1 机器人回复 APP_CARD 支付链接.

2 机器人回复 APP_BUTTON_GROUP 支付链接.

? or help : 显示帮助

点击上面的链接，将会弹出一个窗口，输入你的密码，将支付币给机器人!

Mixin Messenger支持的消息类型

如下图所示，用户点击支付链接，输入密码，支付0.01 EOS给机器人，机器人马上返还给用户！

亲爱的开发者，你也可以从消息控制面板里，点击转帐，直接将币转给机器人！它还是一样的立即返还！

源代码解释

$msg = new Frame(gzencode(json_encode($msgData)),true,Frame::OP_BINARY);
$conn->send($msg);

机器人发送给用户的消息，先用json序列化，再用gzencode压缩。

if ($jsMsg->data->category === "SYSTEM_ACCOUNT_SNAPSHOT") {
  // refundInstant
    echo "user id:".$jsMsg->data->user_id;
    $dtPay = json_decode(base64_decode($jsMsg->data->data));
    print_r($dtPay);
    if ($dtPay->amount > 0) {
      echo "paid!".$dtPay->asset_id;
      refundInstant($dtPay->asset_id,$dtPay->amount,$jsMsg->data->user_id);
    }
} //end of SYSTEM_ACCOUNT_SNAPSHOT

如果机器人收到币，

$dtPay->amount

大于零；如果机器人支付币给用户，接收到的消息是一样的，唯一不同的是

$dtPay->amount

是一个负数.

function refundInstant($_assetID,$_amount,$_opponent_id) {
  $mixinSdk = new MixinSDK(require "./config.php");
  // print_r();
  $BotInfo = $mixinSdk->Wallet()->transfer($_assetID,$_opponent_id,
                                           $mixinSdk->getConfig()["default"]["pin"],$_amount);
  print_r($BotInfo);
}

最后一步，调用MixinSDK将币还给用户！
