在Ubuntu机器上构建go代码时遇到错误。我检查了GOPATH变量，一切似乎都很好。下面是我得到的错误的堆栈跟踪：
/ go / src / Chaincodeexample $ go build＃_ / home / ubuntu / go / src / Chaincodeexample
./Samplesupplychain.go:13:14: cannot refer to unexported name shim.logger
./Samplesupplychain.go:91:5: syntax error: non-declaration statement outside function body
下面是我的代码：
import(
"errors"
"fmt"
"encoding/json"
"github.com/hyperledger/fabric/core/chaincode/shim"
)
var logger = shim.logger("my logger")
//Create a struct for these 2 values
type testuser struct{
Username string `json:"username"`
Fileuploaded string `json:"fileuploaded"`
}
//A function to create a user on the ledger
func CreateUser(stub shim.ChaincodeStubInterface, args []string) ([]byte, error){
if len(args) < 2 {
logger.Error("Invalid number of args")
return nil, errors.New("Expected atleast 1 argument for user creation")
}
var Username = args[0]
var UsernameInput = args[1]
//trying to understand
err := stub.PutState(Username, []byte(UsernameInput))
if err != nil {
logger.Error("Could not save new User to ledger", err)
return nil, err
}
var customEvent = "{eventType: 'UserCreation', description:" + Username + "' Successfully created'}"
err = stub.SetEvent("evtSender", []byte(customEvent))
if err != nil {
return nil, err
}
logger.Info("Successfully saved a supply chain user")
return nil, nil
}
func Checkuploadstatus(stub shim.ChaincodeStubInterface, args []string) ([]byte, error) {
logger.Debug("Entering supply-chain application")
if len(args) < 1 {
logger.Error("Invalid number of arguments")
return nil, errors.New("Missing details")
}
var Fileuploadedstatus = args[0]
bytes, err := stub.GetState(Fileuploadedstatus)
if err != nil {
logger.Error("Could not fetch Fileuploadedstatus with "+ Fileuploadedstatus +" from ledger", err)
return nil, err
}
return bytes, nil
}
给我想法解决这个问题。
