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。 完整代码如下：

复制代码 你好, 比特币!

The bot is listening!
复制代码开发者可以通过消息面板，给机器人转比特币，当机器人收到比特币后，马上返还给用户！
事实上，用户可以发送任意的币种给机器人，它都能马上返还！
源代码解释
if (incomingMessage.data.category == "SYSTEM_ACCOUNT_SNAPSHOT") {
byte[] strOriginal = Convert.FromBase64String(incomingMessage.data.data);
string clearText = System.Text.Encoding.UTF8.GetString(strOriginal);
Transfer trsInfo = JsonConvert.DeserializeObject(clearText);
if ( Int32.Parse(trsInfo.amount) > 0 ) {
Transfer reqInfo = callback.Transfer(trsInfo.asset_id,
trsInfo.opponent_id,
trsInfo.amount,
USRCONFIG.PinCode,
System.Guid.NewGuid().ToString(),
"");
Console.WriteLine(reqInfo);
}
复制代码 如果机器人收到币，trsInfo.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,trsInfo.amount是一个负数. 最后一步，调用SDK的 callback.Transfer 将币返还用户！
高级用法
APP_BUTTON_GROUP
在一些应用场景，比如：有一个交易所想提供换币服务，将比特币换成以太坊，EOS,比特币现金等, 你想显示给用户一组按钮，它们分别代表不同的币与不同的数量,APP_BUTTON_GROUP可以帮你做到这一点.
List appBtnList = new List();
string payLinkEOS = "https://mixin.one/pay?recipient=" +
USRCONFIG.ClientId + "&asset=" +
"6cfe566e-4aad-470b-8c9a-2fd35b49c68d" +
"&amount=" + "0.1" +
"&trace=" + System.Guid.NewGuid().ToString() +
"&memo=";
string payLinkBTC = "https://mixin.one/pay?recipient=" +
USRCONFIG.ClientId + "&asset=" +
"c6d0c728-2624-429b-8e0d-d9d19b6592fa" +
"&amount=" + "0.001" +
"&trace=" + System.Guid.NewGuid().ToString() +
"&memo=";
AppButton btnBTC = new AppButton();
btnBTC.label = "Pay BTC 0.001";
btnBTC.color = "#0080FF";
btnBTC.action = payLinkBTC;
AppButton btnEOS = new AppButton();
btnEOS.label = "Pay EOS 0.1";
btnEOS.color = "#8000FF";
btnEOS.action = payLinkEOS;
appBtnList.Add(btnBTC);
appBtnList.Add(btnEOS);
callback.SendAppButtonGroupMessage(incomingMessage.data.conversation_id,appBtnList);
复制代码 这里演示给用户BTC与EOS两种，你还可以增加更多的按钮.
APP_CARD
如果你觉得一组按钮太单调了，可以试一下APP_CARD,它提供一个图标的链接
AppCard appCard = new AppCard();
appCard.title = "Pay BTC 0.0001";
appCard.icon_url = "https://images.mixin.one/HvYGJsV5TGeZ-X9Ek3FEQohQZ3fE9LBEBGcOcn4c4BNHovP4fW4YB97Dg5LcXoQ1hUjMEgjbl1DPlKg1TW7kK6XP=s128";
appCard.description = "hi";
appCard.action = "https://mixin.one/pay?recipient=" +
USRCONFIG.ClientId + "&asset=" +
"c6d0c728-2624-429b-8e0d-d9d19b6592fa" +
"&amount=" + "0.001" +
"&trace=" + System.Guid.NewGuid().ToString() +
"&memo=";
callback.SendAppCardMessage(incomingMessage.data.conversation_id,appCard);
