实例化链码时出错 [英] Error when instantiate chaincode

问题描述

请帮助我解决这个问题，当我实例化我的链码时发生错误:

Please help me this issue, error happened when I instantiate my chaincode:

当前，我猜是与shim软件包有关的问题，因为我已将其删除到utils软件包中，成功实例化了.

Currently, I guess the issue related to shim package, because I remove it in my utils package, instantiate successfully.

import (
    "bytes"
    "encoding/hex"
    "encoding/json"
    "fmt"
    "strconv"

    "github.com/golang/protobuf/proto"
    "github.com/hyperledger/fabric/core/chaincode/shim"
    "github.com/hyperledger/fabric/protos/msp"
    pb "github.com/hyperledger/fabric/protos/peer"
    "github.com/myproj/models"
    "github.com/myproj/packages/utils"
)

APIstub shim.ChaincodeStubInterface
...
username, _ = utils.GetCurrentUser(APIstub)
...

我的包裹

package utils

import (
    "github.com/hyperledger/fabric/core/chaincode/shim"
    "golang.org/x/crypto/bcrypt"
)

func GetCurrentUser(stub shim.ChaincodeStubInterface) (string, error) {
    cert, err := GetCreatorCert(stub)

    return cert.Subject.CommonName, err
}

织物版本1.1.0

转到1.9.2版

推荐答案

将结构升级到1.2.0后，我遇到了同样的问题. Fabric 1.2.0需要go1.10.x.所以我将go lang升级到1.10.3，它像一个魅力一样工作.

I faced the same problem after upgrading fabric to 1.2.0. Fabric 1.2.0 requires go 1.10.x. So I upgraded go lang to 1.10.3 and it worked like a charm.
