I want to test my chaincode by Golang, so I have used Hyperledger fabric chaincodedev test.

All functions of chaincode (invoke, query, etc.) worked, but there are no logs and messages of chaincode on console.

Logging is set to "debug" in every case.

I want to print out result message of invoke, query on console, but just print out message: "myc"; "myc"; "myc"; ...

    It's look like fmt.Println output.

    But you can user


    You can found an example of shim logger :

    The logs for chaincodes are in their respective containers. So for a chaincode called mycc at version 1.0 on peer0 of org, I'd run:

    docker logs -f

    to see the output of any fmt.Print*s.

    Just in case someone is unfamiliar, you can view your containers with docker ps and the chaincode container is created after you install a chaincode and run instantiate on a new chaincode or upgrade an existing one (this creates a new container, hence the version in the container name above).
