我如何将令牌从节点移动到Corda中的帐户

Question

我使用Corda代币SDK和Corda帐户。（Corda_version = 4.1，tokens_version = 1.0，accounts_version = 1.0-rc04）

我刚刚构建了一个简单的场景：流程_1。 PartyA节点创建帐户“ lisa”

start CreateAccount name: "lisa"

Flow_2。 PartA节点向自身发行令牌

Party notary = getServiceHub().getNetworkMapCache().getNotaryIdentities().get(0);
MyEvolvableToken myEvolvableToken = new MyEvolvableToken(...);
TransactionState<MyEvolvableToken> transactionState = new TransactionState<>(myEvolvableToken, notary);
subFlow(new CreateEvolvableTokens(myEvolvableToken));

・
//issue token to self
FungibleToken fungibleToken = new FungibleToken(amount, partya,TransactionUtilitiesKt.getAttachmentIdForGenericParam(tokenPointer))
return subFlow(new IssueTokens(ImmutableList.of(fungibleToken)));

Flow_3。 PartA节点将令牌移动到“ lisa”

//Get Token from db
MyEvolvableToken token = stateAndRef.getState().getData();
TokenPointer tokenPointer = token.toPointer(token.getClass());
//Get Account from db
stateAndRefAccount = subFlow(new AccountInfoByName("lisa")).get(0);
AccountInfo lisaAccount = stateAndRefAccount.getState().getData();
//fresh account publicKey
PublicKey key = getServiceHub().getKeyManagementService().freshKey(lisaAccount.getIdentifier().getId()); 
AnonymousParty lisaParty = new AnonyMousParty(key);
//specify amount token to transfer
Amount<TokenPointer> amount = new Amount(10,tokenPointer);
PartyAndAmount partyAndAmount = new PartyAndAmount(lisaParty,amount);
return subFlow(new MoveFungibleTokens(partyAndAmount));

但是，当我启动Flow_3时出现错误。AnonymousParty无法正常工作？如何将令牌从节点转移到帐户？

java.lang.IllegalArgumentException: Called flow with anonymous party that node doesn't know about.Make sure that RequestConfidentialIdentity flow is called before.

Answer 1

请参阅有关帐户+令牌集成的最新示例：https://github.com/corda/samples-java/tree/master/Accounts/worldcupticketbooking

要回答有关如何从节点到帐户发行令牌的问题，您可以将令牌直接发行到帐户的匿名方

例如：

//mention the current holder which is now going to be the dealer account 
NonFungibleToken nonFungibleToken = new NonFungibleToken(issuedTokenType, dealerAccount, new UniqueIdentifier(),TransactionUtilitiesKt.getAttachmentIdForGenericParam(tokenPointer)); 

//call built in flow to issue non fungible tokens 
SignedTransaction stx =  subFlow(new IssueTokens(Arrays.asList(nonFungibleToken)));

dealerAccount是一个匿名方。
