IBM hyperlegder面料Bluemix实现 - errror部署chaincode

Question

时，虽然按照“中的步骤部署你的chaincode从IBM BluemixBlockchain文档，我发现了以下错误：

响应体

    "jsonrpc": "2.0", 
    "error": { 
    "code": -32001, 
    "message": "Deployment failure",

    },

} 

参考以下链接： IBM Blockchain (Hyperledger) - "Error when deploying chaincode"

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

go代码正确地构建，但仍然出现'Shim interface'问题的失败错误。 Go代码仍然有问题吗？

Answer 1

此问题似乎与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)。

有关适用于Hyperledger Fabric版本0.6.1的链式代码示例，请参阅https://github.com/IBM-Blockchain/learn-chaincode/blob/v2.0/finished/chaincode_finished.go上的“了解Chaincode”示例链接代码。请注意，Init函数的签名是Init(stub shim.ChaincodeStubInterface, function string, args []string) ([]byte, error)。
