如何在Corda中将令牌从节点移动到帐户

Question

我使用Corda token 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：
Flow_1.PartyA节点创建帐户“lisa”

start CreateAccount name: "lisa"

Flow_2。PartA-节点向自身颁发令牌

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。部分节点将令牌移动到“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时出现了一个错误。< br >匿名聚会不起作用？？< br >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.

请参考我们关于帐户令牌集成的最新示例:https://github . com/corda/samples-Java/tree/master/Accounts/worldcupticketbooking

要回答如何从节点向帐户颁发令牌的问题，您可以直接向帐户的匿名方颁发令牌

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)));

其中经销商帐户是匿名方。
