我正在测试具有区域约束的Corda 4.1开源，我有4个节点，分别是Node A，Node B，Node C和Notary（Notary是Corda 4.1的CE版本）
我运行 IssueFlow 来创建从节点B到节点A的 StateA 。 并在提交事务节点A的子流程后的IssueFlow.Responder中，通过 TestFlow 来更新 StateA ，这会将Node C添加到 StateA 的参与者中
这是IssueFlow.Responder中的代码
@InitiatedBy(IssueFlow.Initiator::class)
class Responder(val otherFlow: FlowSession) : FlowLogic<SignedTransaction>() {
@Suspendable
override fun call(): SignedTransaction {
val flow = object : SignTransactionFlow(otherFlow) {
@Suspendable
override fun checkTransaction(stx: SignedTransaction) {
// Custom validation here
}
}
val stx = subFlow(flow)
val waitForLedgerCommit = subFlow(ReceiveFinalityFlow(otherFlow, stx.id))
executableAfterCommit(waitForLedgerCommit)
return waitForLedgerCommit
}
@Suspendable
private fun executableAfterCommit(stx: SignedTransaction) {
val listOfStateA = stx.tx.outputsOfType<StateA>()
require(listOfStateA.size == 1) { "Only one document of StateA is allowed in the transaction." }
val stateA = listOfStateA.single()
subFlow(TestFlow.Initiator(listOf(stateA.linearId.id.toString())))
}
}
在TestFlow中，我将更新 StateA 的一些信息，并将Node C添加为其他参与者，但我只希望NodeA和NodeB进行签名。 代码如下：
object TestFlow {
@InitiatingFlow
@StartableByRPC
class Initiator(private val linearId: String) : FlowLogic<SignedTransaction>() {
override val progressTracker: ProgressTracker()
val window by lazy { TimeWindow.withTolerance(currentClock.instant(), 30.minutes) }
@Suspendable
override fun call(): SignedTransaction {
val stx = collectSignatures(verifyAndSign(build()))
val sessions = transaction.sessionsOfParticipants()
return subFlow(FinalityFlow(stx, sessions))
}
private fun build(): TransactionBuilder {
val statesIn = queryByLinear(listOf(linearId.toUUID())).single()
val stateOut = stateIn.changeData("field1").addParticipants(NodeC)
val result = TransactionBuilder(firstNotary).apply {
// Add inputs
withItems(statesIn)
// Add outputs
withItems(StateAndContract(stateOut, StateAContract.CONTRACT_ID))
// Signer only NodeA and NodeB
val listOfSigner = listOf(statesIn.state.data, stateOut)
.selectKeysOf(addNodeA = true, addNodeB = true)
.toList()
// Add commands
addCommand(StateAContract.Commands.Test(), listOfSigner)
setTimeWindow(window)
}
return result.toLedgerTransaction(serviceHub)
}
private fun verifyAndSign(transaction: TransactionBuilder): SignedTransaction {
transaction.verify(serviceHub)
return serviceHub.signInitialTransaction(transaction)
}
@Suspendable
private fun collectSignatures(transaction: SignedTransaction): SignedTransaction {
val signers = excludeNotary(groupPublicKeysByWellKnownParty(serviceHub, transaction.getMissingSigners()), transaction).map { it.key }
return subFlow(CollectSignatureInitiator(transaction, signers))
}
}
@InitiatedBy(Initiator::class)
class Responder(private val otherFlow: FlowSession) : FlowLogic<SignedTransaction>() {
@Suspendable
override fun call(): SignedTransaction {
return subFlow(ReceiveFinalityFlow(otherFlow))
}
}
/**
* Collect signature initiating flow
*/
@InitiatingFlow
class CollectSignatureInitiator(private val transaction: SignedTransaction, private val signers: List<Party>) : FlowLogic<SignedTransaction>() {
@Suspendable
override fun call(): SignedTransaction {
val sessions = signers.map { initiateFlow(it) }
return subFlow(CollectSignaturesFlow(transaction, sessions))
}
}
/**
* Collect signature responder flow
*/
@InitiatedBy(CollectSignatureInitiator::class)
class CollectSignatureResponder(private val session: FlowSession) : FlowLogic<SignedTransaction>() {
@Suspendable
override fun call(): SignedTransaction {
return subFlow(object : SignTransactionFlow(session) {
override fun checkTransaction(stx: SignedTransaction) {
subFlow(ValidateDocument(session, stx))
return
}
})
}
}
}
并且TestFlow在Node C中引发错误，如下所示：
