基于Mixin Network的Go语言比特币开发教程 : 用 Mixin Messenger 机器人接受和发送比特币
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：
main.go
fpackage main
import (
"context"
"encoding/base64"
"encoding/json"
"log"
"github.com/MooooonStar/mixin-sdk-go/messenger"
mixin "github.com/MooooonStar/mixin-sdk-go/network"
)
type Listener struct {
*messenger.Messenger
}
// 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(),
PinCode,PinToken,UserId,SessionId,PrivateKey)
return nil
// return l.SendPlainText(ctx, msg.ConversationId, msg.UserId, string(data))
} else if msg.Category == "PLAIN_TEXT" {
log.Printf("I got a message, it said: %s", string(data))

你好, 比特币!
在项目目录下编译并执行
cd mixin_labs-go-bot
go build
./mixin_labs-go-bot
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 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))
}
调用SDK的 mixin.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.
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
}
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
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
}
