如何从字符串创建聚会对象？

Question

给定mystring =“ O = PartyB，L = New York，C = US”，有没有一种简单的方法可以将字符串转换为真实的Party对象？一直在查看CordaRPCOps.wellKnownPartyFromX500Name（），但无法使其正常工作...已尝试以下变化：

val rpcOps = new CordaRPCOps()
val otherParty: Party = rpcOps.wellKnownPartyFromX500Name(partyString) ?: throw Exception("Party not recognised.")

Answer 1

有几种方法可以执行此操作：

将字符串解析为X500名称

val x500Name = CordaX500Name.parse("O=PartyB,L=New York,C=US")
val party = rpcOps.wellKnownPartyFromX500Name(x500Name)

直接构造X500名称

val x500Name = CordaX500Name(organisation = "PartyB", locality = "New York", country = "US")
val party = rpcOps.wellKnownPartyFromX500Name(x500Name)

模糊匹配

val matchingParties = rpcOps.partiesFromName("PartyB", false)
if (matchingParties.size != 1) {
    throw IllegalArgumentException()
}
val party2 = matchingParties.single()

获取CordaRPCOps实例

这是一个如何首先获得CordaRPCOps实例的示例：

val rpcAddress = NetworkHostAndPort(host, rpcPort)
val rpcClient = CordaRPCClient(rpcAddress)
val rpcConnection = rpcClient.start(username, password)
val cordaRPCOps = rpcConnection.proxy
