基于Mixin Network的PHP比特幣開發教程: 機器人接受比特幣并立即退還用戶

摘要：如果機器人收到幣，大于零如果機器人支付幣給用戶，接收到的消息是一樣的，唯一不同的是是一個負數最后一步，調用將幣還給用戶完整的代碼在這兒

在上一篇教程中, 我們創建了自動回復消息的機器人,當用戶發送消息"Hello,World!"時，機器人會自動回復同一條消息!

按本篇教程后學習后完成后，你的機器人將會接受用戶發送過來的加密貨幣，然后立即轉回用戶。下面是全部源代碼，創建一個app.php試一下吧！

你好，我的幣!

在工程目錄下，執行 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
)

如果控制臺出現 "LIST_PENDING_MESSAGES"字樣, 連接到mixin.one成功了，正在偵聽用戶發送消息給它!

按幫助來操作,發送消息得到相應的支付提示

1 機器人回復 APP_CARD 支付鏈接.

2 機器人回復 APP_BUTTON_GROUP 支付鏈接.

? or help : 顯示幫助

點擊上面的鏈接，將會彈出一個窗口，輸入你的密碼，將支付幣給機器人!

Mixin Messenger支持的消息類型

如下圖所示，用戶點擊支付鏈接，輸入密碼，支付0.01 EOS給機器人，機器人馬上返還給用戶！

親愛的開發者，你也可以從消息控制面板里，點擊轉帳，直接將幣轉給機器人！它還是一樣的立即返還！

源代碼解釋

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

機器人發送給用戶的消息，先用json序列化，再用gzencode壓縮。

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

如果機器人收到幣，

$dtPay->amount

大于零；如果機器人支付幣給用戶，接收到的消息是一樣的，唯一不同的是

$dtPay->amount

是一個負數.

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，調用MixinSDK將幣還給用戶！
