Getting error as : Error: Client.createUser parameter 'opts mspid' is required

Question

我正在尝试使用 IBM 区块链。我已经在 IBM 区块链上创建了设置，现在我正尝试通过 IBM 区块链上的节点 SDK 注册用户，但是，当我尝试将应用程序管理员注册到 IBM 区块链时，我遇到了问题。

请帮我找出问题所在，或者让我知道哪里做错了。

如果我遗漏了什么，请告诉我。并感谢您的提前。

Answer 1

您传递给 createIdentity 的 mspid 值为空。在您的配置中，您将 msp id 定义为

"orgMSPIiD": "dFarmMSP",

而在您的代码中您尝试将其检索为

var orgMSPID = config1.orgMSPID;

（注意 iD 与 ID 之间的区别）

所以基本上 orgMSPID 的值将是 undefined。

但是，由于没有给出 mspid，因此 createIdentity 报告错误会很有用，因此我建议您在 https://jira.hyperledger.org 为 fabric-sdk-node 项目 (FABN) 提出一个 jira，并建议createIdentity 应检查输入参数中是否存在未定义的 mspid
