tsunagi-functions for Go

関数群の提供のため、sdkという名称は今後functionsに変更予定です。

実装例

まずは簡単な実装例を紹介します。

転送トランザクション

func getNetworkInfo() map[string]any {
	return map[string]any{
		"version":1,
		"network":"TESTNET",
		"generationHash":"7fccd304802016bebbcd342a332f91ff1f3bb5e902988b352697be245f48e836",
		"epochAdjustment":1637848847,
		"catjasonBase":"https://xembook.github.io/tsunagi-sdk/catjson/",
	}
}

func getDeadline(network map[string]any) int {
	//	now := time.Now()
	now := network["epochAdjustment"].(int)
	deadline := ((now + 7200) - network["epochAdjustment"].(int)) * 1000
	return deadline
}

func getPayload(tx map[string]any,network map[string]any) string {
	catjson := loadCatjson(tx,network)
	layout := loadLayout(tx,catjson,false)
	preparedTx := prepareTransaction(tx,layout,network) //TX事前準備
	parsedTx := parseTransaction(preparedTx,layout,catjson,network)
	builtTx := buildTransaction(parsedTx) 
	signature := signTransaction(builtTx,"94ee0f4d7fe388ac4b04a6a6ae2ba969617879b83616e4d25710d688a89d80c7",network)
	builtTx = updateTransaction(builtTx,"signature","value",signature)
	//	txHash := hashTransaction(tx1["signer_public_key"].(string),signature,builtTx,network);
	payload := hexlifyTransaction(builtTx,0)
	return payload
}

network  := getNetworkInfo()
deadline := getDeadline(network)

tx1 := map[string]any{
	"type" : "TRANSFER",
	"signer_public_key" : "5f594dfc018578662e0b5a2f5f83ecfb1cda2b32e29ff1d9b2c5e7325c4cf7cb",
	"fee" : 25000,
	"deadline" : deadline,
	"recipient_address" : generateAddressId("TCO7HLVDQUX6V7C737BCM3VYJ3MKP6REE2EKROA"),

	},
	"message" : "Hello Tsunagi(Catjson) SDK!",
}

payload := getPayload(tx1,network)

通知

	client := &http.Client{}
	json, _ := json.Marshal(payload)
	req , _ := http.NewRequest(http.MethodPut, "https://sym-test-02.opening-line.jp:3001/transactions", bytes.NewBuffer(json))
	req.Header.Set("Content-Type", "application/json; charset=utf-8")
	resp, _ := client.Do(req)
	fmt.Println(resp.StatusCode)

連署

連署を必要とするトランザクションの場合は、tx1 に加えて以下のような定義と署名の追加が必要になります。


cosignature1 := map[string]any{
	"version":0,
	"signer_public_key":"6199bae3b241df60418e258d046c22c8c1a5de2f4f325753554e7fd9c650afec",
	"signature":"",
}

cosignature2 := map[string]any{
	"version":0,
	"signer_public_key":"886adfbd4213576d63ea7e7a4bece61c6933c27cd2ff36f85155c8febfb6eb4e",
	"signature":"",
}

aggTx := map[string]any{
	"type" : "AGGREGATE_COMPLETE",
	"signer_public_key" : "5f594dfc018578662e0b5a2f5f83ecfb1cda2b32e29ff1d9b2c5e7325c4cf7cb",
	"fee" : 1000000,
	"deadline" : deadline,
	"transactions": []any{tx1,tx2,tx3},
	"cosignatures": []any{cosignature1,cosignature2},
}

catjson := loadCatjson(aggTx,network)
layout := loadLayout(aggTx,catjson,false)
preparedTx := prepareTransaction(aggTx,layout,network) //TX事前準備
parsedTx := parseTransaction(preparedTx,layout,catjson,network)
builtTx := buildTransaction(parsedTx) 
signature := signTransaction(builtTx,"94ee0f4d7fe388ac4b04a6a6ae2ba969617879b83616e4d25710d688a89d80c7",network)
builtTx = updateTransaction(builtTx,"signature","value",signature)
txHash := hashTransaction(aggTx["signer_public_key"].(string),signature,builtTx,network);

preparedTx["cosignatures"].([]any)[0].(map[string]any)["signature"] = cosignTransaction(txHash,"fa6373f4f497773c5cc55c103e348b139461d61fd4b45387e69d08a68000e06b")
preparedTx["cosignatures"].([]any)[1].(map[string]any)["signature"] = cosignTransaction(txHash,"1e090b2a266877a9f88a510af2eb0945a63dc69dbce674ccd83272717d4175cf")

idx := slices.IndexFunc(layout, func(item any) bool {return item.(map[string]any)["name"] == "cosignatures"})
if idx >= 0 {
	cosignaturesLayout := layout[idx].(map[string]any)
	parsedCosignatures := parseTransaction(preparedTx,[]any{cosignaturesLayout},catjson,network)
	builtTx = updateTransaction(builtTx,"cosignatures","layout",parsedCosignatures[0].(map[string]any)["layout"])
}
payload := hexlifyTransaction(builtTx,0);

他にもテストスクリプトに様々なトランザクションを記述しているのでぜひお試しください！
