使用节点 SDK 在 hyperledger fabric 中注册和注册时遇到错误

Question

我需要帮助。我正在使用 2Orgs.The 开发自定义 HLF 网络 Fabric 网络与 cli 完美配合，当我想连接节点 sdk 时，出现错误。我成功注册了管理员，但未能注册用户，并且在注册和注册用户 1 时遇到错误。you can see the error and ca container logs。文件如下所述提前致谢

Answer 1

正如您的错误消息所说，user1 已经在 ca 服务器上注册，因此您必须重新启动网络，或者您必须从 ca 服务器中删除该身份。我建议您重新启动网络并从钱包文件夹中删除所有内容，然后它将起作用。或者用不同的身份试试，比如 user

Answer 2

您似乎已经 "user1" 注册了。尝试删除注册生成的本地文件，或者您应该动态设置用户注册
