署名待ちの アグリゲート トランザクションに署名
このガイドでは、あなたがアグリゲートトランザクションを受信したことを前提とします。ガイド エスクローコントラクトの作成 に従って、アグリゲートトランザクションをアナウンスできます。
署名されるのを待機しているアグリゲートボンデッドトランザクションがある連署者アカウントにログインします。
ホームで “partial” タブをクリックします。トランザクションリストをクリックし、ウォレットのパスワードを入力してトランザクションに署名します。
1. First, check if your account has incoming aggregate transactions that have not been signed.
Use the TransactionHttp repository to search all the incoming aggregate transactions pending to be signed by your account.
// replace with account address
const rawAddress = 'TAXQUT-QQNS6J-EJG7PL-C6FRVJ-2USS44-GLMVUL-PGQ';
const address = Address.createFromRawAddress(rawAddress);
const nodeUrl = 'NODE_URL';
const repositoryFactory = new RepositoryFactoryHttp(nodeUrl);
const transactionHttp = repositoryFactory.createTransactionRepository();
const searchCriteria = {
group: TransactionGroup.Partial,
address,
pageNumber: 1,
pageSize: 100,
};
transactionHttp.search(searchCriteria).subscribe(
(page) => console.log(page.data),
(err) => console.error(err),
);
// replace with account address
const rawAddress = 'TAXQUT-QQNS6J-EJG7PL-C6FRVJ-2USS44-GLMVUL-PGQ';
const address = symbol_sdk_1.Address.createFromRawAddress(rawAddress);
const nodeUrl = 'NODE_URL';
const repositoryFactory = new symbol_sdk_1.RepositoryFactoryHttp(nodeUrl);
const transactionHttp = repositoryFactory.createTransactionRepository();
const searchCriteria = {
group: symbol_sdk_1.TransactionGroup.Partial,
address,
pageNumber: 1,
pageSize: 100,
};
transactionHttp.search(searchCriteria).subscribe((page) => console.log(page.data), (err) => console.error(err));
TransactionRepository transactionHttp = repositoryFactory.createTransactionRepository();
TransactionPaginationStreamer streamer = new TransactionPaginationStreamer(transactionHttp);
List<Transaction> transactions = streamer.search(new TransactionSearchCriteria(TransactionGroup.PARTIAL))
.toList().toFuture().get();
System.out.println(transactions);
あなたのアカウントで連署名するトランザクションハッシュをコピーして保存します。
AggregateBondedTransaction を共同署名する関数を作成します。
const cosignAggregateBondedTransaction = (
transaction: AggregateTransaction,
account: Account,
): CosignatureSignedTransaction => {
const cosignatureTransaction = CosignatureTransaction.create(transaction);
return account.signCosignatureTransaction(cosignatureTransaction);
};
const cosignAggregateBondedTransaction = (transaction, account) => {
const cosignatureTransaction = symbol_sdk_1.CosignatureTransaction.create(transaction);
return account.signCosignatureTransaction(cosignatureTransaction);
};
BiFunction<AggregateTransaction, Account, CosignatureSignedTransaction> cosignAggregateBondedTransaction = ((transaction, account) -> CosignatureTransaction
.create(transaction).signWith(account));
3. Define the transaction hash to cosign and the signer account. If you want to cosign a transaction involving a multisig account, you should be using the cosignatory account instead.
// replace with network type
const networkType = NetworkType.TEST_NET;
// replace with private key
const privateKey =
'0000000000000000000000000000000000000000000000000000000000000000';
const account = Account.createFromPrivateKey(privateKey, networkType);
// replace with node endpoint
// replace with transaction hash to cosign
const transactionHash =
'0000000000000000000000000000000000000000000000000000000000000000';
// replace with network type
const networkType = symbol_sdk_1.NetworkType.TEST_NET;
// replace with private key
const privateKey = '0000000000000000000000000000000000000000000000000000000000000000';
const account = symbol_sdk_1.Account.createFromPrivateKey(privateKey, networkType);
// replace with node endpoint
// replace with transaction hash to cosign
const transactionHash = '0000000000000000000000000000000000000000000000000000000000000000';
NetworkType networkType = repositoryFactory.getNetworkType().toFuture().get();
// replace with cosigner private key
String privateKey = "";
Account account = Account.createFromPrivateKey(privateKey, networkType);
// replace with transaction hash to cosign
String transactionHash = "";
4. Retrieve the complete transaction object from the node using the TransactionHttp repository.
At this point, you might want to do some extra checks, like verifying the contents of the transaction.
If everything looks ok, cosign the transaction with the signer account.
Finally, announce the cosignature to network with transactionHttp.announceAggregateBondedCosignature.
const nodeUrl = 'NODE_URL';
const repositoryFactory = new RepositoryFactoryHttp(nodeUrl);
const transactionHttp = repositoryFactory.createTransactionRepository();
transactionHttp
.getTransaction(transactionHash, TransactionGroup.Partial)
.pipe(
map((transaction) =>
cosignAggregateBondedTransaction(
transaction as AggregateTransaction,
account,
),
),
mergeMap((cosignatureSignedTransaction) =>
transactionHttp.announceAggregateBondedCosignature(
cosignatureSignedTransaction,
),
),
)
.subscribe(
(announcedTransaction) => console.log(announcedTransaction),
(err) => console.error(err),
);
const nodeUrl = 'NODE_URL';
const repositoryFactory = new symbol_sdk_1.RepositoryFactoryHttp(nodeUrl);
const transactionHttp = repositoryFactory.createTransactionRepository();
transactionHttp
.getTransaction(transactionHash, symbol_sdk_1.TransactionGroup.Partial)
.pipe((0, operators_1.map)((transaction) => cosignAggregateBondedTransaction(transaction, account)), (0, operators_1.mergeMap)((cosignatureSignedTransaction) => transactionHttp.announceAggregateBondedCosignature(cosignatureSignedTransaction)))
.subscribe((announcedTransaction) => console.log(announcedTransaction), (err) => console.error(err));
TransactionRepository transactionHttp = repositoryFactory.createTransactionRepository();
TransactionAnnounceResponse announcedTransaction = transactionHttp
.getTransaction(TransactionGroup.PARTIAL, transactionHash)
.map(transaction -> cosignAggregateBondedTransaction.apply((AggregateTransaction) transaction, account))
.flatMap(transactionHttp::announceAggregateBondedCosignature).toFuture().get();
System.out.println(announcedTransaction);
