尝试参考链接： IBM Blockchain (Hyperledger) - "Error when deploying chaincode"

"Error getting chaincode package bytes" when deploying chaincode on hyperledger via REST

go代码构建正确，但我仍然遇到“Shim interface”问题导致此失败错误。 Go代码中还有什么问题吗？

Answer 1

该问题似乎与Asgn1.go文件中的Go代码有关。该消息表明Init函数的签名是Init(shim.ChaincodeStubInterface) ([]byte, error)而不是Init(shim.ChaincodeStubInterface, string, []string) ([]byte, error)。

有关与Hyperledger Fabric版本0.6.1一起使用的示例链代码，请参阅https://github.com/IBM-Blockchain/learn-chaincode/blob/v2.0/finished/chaincode_finished.go处的“Learn Chaincode”示例链代码。请注意，Init函数的签名是Init(stub shim.ChaincodeStubInterface, function string, args []string) ([]byte, error)。
