基于 Mixin Network 的 Go 语言比特币开发教程：使用 Mixin Messenger bot 接收和发送比特币
在上一个教程中，我们创建了一个自动回复消息的机器人。当用户发送消息“Hello, World!”时，机器人会自动回复相同的消息！
完成本教程后，您的机器人将接受用户发送的加密货币并立即将其转回给用户。完整代码如下：

}
// interface to implement if you want to handle the message
func (l *Listener) OnMessage(ctx context.Context, msg messenger.MessageView, userId string) error {
data, err := base64.StdEncoding.DecodeString(msg.Data)
if err != nil {
return err
}
if msg.Category == "SYSTEM_ACCOUNT_SNAPSHOT" {
var transfer messenger.TransferView
if err := json.Unmarshal(data, &transfer); err != nil {
return err
}
log.Println("I got a coin: ", transfer.Amount)
mixin.Transfer(msg.UserId,transfer.Amount,transfer.AssetId,"",messenger.UuidNewV4().String(),

你好nbtc新比特币合约地址，比特币！
在项目目录下编译执行
cd mixin_labs-go-bot
go build
./mixin_labs-go-bot复制
开发者可以通过消息面板将比特币转给机器人，当机器人收到比特币后，会立即返还给用户！
事实上，用户可以向机器人发送任何货币，它会立即被退回！
源代码解释
if msg.Category == "SYSTEM_ACCOUNT_SNAPSHOT" {
var transfer messenger.TransferView
if err := json.Unmarshal(data, &transfer); err != nil {
return err
}
log.Println("I got a coin: ", transfer.Amount)
mixin.Transfer(msg.UserId,transfer.Amount,transfer.AssetId,"",messenger.UuidNewV4().String(),
PinCode,PinToken,UserId,SessionId,PrivateKey)
return nil
// return l.SendPlainText(ctx, msg.ConversationId, msg.UserId, string(data))
}复制
调用 SDK 的 mixin.Transfer 将币返还给用户！
高级使用APP_BUTTON_GROUP
在一些应用场景中，例如：一个交易所想提供一种货币兑换服务，将比特币兑换成以太坊、EOS、比特币现金等，你想向用户显示一组按钮，代表不同的币种和不同的数量, APP_BUTTON_GROUP 可以为您做到这一点。
payLinkEOS := "https://mixin.one/pay?recipient=" +
msg.UserId + "&asset=" +
"6cfe566e-4aad-470b-8c9a-2fd35b49c68d" +
"&amount=" + "0.1" +
"&trace=" + messenger.UuidNewV4().String() +
"&memo="
payLinkBTC := "https://mixin.one/pay?recipient=" +
msg.UserId + "&asset=" +
"c6d0c728-2624-429b-8e0d-d9d19b6592fa" +
"&amount=" + "0.001" +
"&trace=" + messenger.UuidNewV4().String() +
"&memo="
log.Println(payLinkBTC)
BtnEOS := messenger.Button{Label: "Pay EOS 0.1", Color: "#0080FF", Action: payLinkEOS}
BtnBTC := messenger.Button{Label: "Pay BTC 0.001", Color: "#00FF80", Action: payLinkBTC}
if err := l.SendAppButtons(ctx, msg.ConversationId, msg.UserId, BtnEOS, BtnBTC); err != nil {
return err
}复制
此演示向用户展示了 BTC 和 EOS，您可以添加更多按钮。
APP_CARD
如果你觉得一组按钮太单调，可以试试APP_CARDnbtc新比特币合约地址，它提供了一个图标的链接
card := messenger.AppCard{Title: "CNB", Description: "Chui Niu Bi", Action: "http://www.google.cn",
IconUrl: "https://images.mixin.one/0sQY63dDMkWTURkJVjowWY6Le4ICjAFuu3ANVyZA4uI3UdkbuOT5fjJUT82ArNYmZvVcxDXyNjxoOv0TAYbQTNKS=s128"}
if err := l.SendAppCard(ctx, msg.ConversationId, msg.UserId, card); err != nil {
return err
}复制
