    这是一个创建于 2129 天前的主题，其中的信息可能已经有所发展或是发生改变。

    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!

    第二课: PHP 机器人接受比特币并立即退还用户

    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！
