基於Mixin Network的C#語言比特幣開發教程 : 用 Mixin Messenger 機器人接受和發送比特幣
在 上一篇教程中, 咱們建立了自動回覆消息的機器人,當用戶發送消息"Hello,World!"時，機器人會自動回覆同一條消息!git
按本篇教程後學習後完成後，你的機器人將會接受用戶發送過來的加密貨幣，而後當即轉回用戶。 完整代碼以下：github

複製代碼
開發者能夠經過消息面板，給機器人轉比特幣，當機器人收到比特幣後，立刻返還給用戶！ 學習
事實上，用戶能夠發送任意的幣種給機器人，它都能立刻返還！ ui
源代碼解釋
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<Transfer>(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);
}
複製代碼
若是機器人收到幣，trsInfo.amount 大於零；若是機器人支付幣給用戶，接收到的消息是同樣的，惟一不一樣的是,trsInfo.amount是一個負數. 最後一步，調用SDK的 callback.Transfer 將幣返還用戶！this
高級用法
APP_BUTTON_GROUP
在一些應用場景，好比：有一個交易所想提供換幣服務，將比特幣換成以太坊，EOS,比特幣現金等, 你想顯示給用戶一組按鈕，它們分別表明不一樣的幣與不一樣的數量,APP_BUTTON_GROUP能夠幫你作到這一點.加密
List<AppButton> appBtnList = new List<AppButton>();
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);

這裏演示給用戶BTC與EOS兩種，你還能夠增長更多的按鈕.url
APP_CARD
若是你以爲一組按鈕太單調了，能夠試一下APP_CARD,它提供一個圖標的連接spa
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() +

callback.SendAppCardMessage(incomingMessage.data.conversation_id,appCard);
