token

README

Shows the use of PutState | GetState | DelState

Test the original token.go

1. Launch the env in dev mode dev-init.sh
2. Setup the env context . set-env.sh acme
3. Setup the chain env set-chain-env.sh -n token -v 1.0 -p token/v5 -c '{"args":[]}'
4. In a new terminal set the env context . set-env.sh acme
5. Install chain.sh install -p
6. Instantiate chain.sh instantiate
7. Follow logs in terminal #1 cc-logs.sh -f
8. Setup invoke & query args set-chain-env.sh -i '{"args":["set"]}' -q '{"args":["get"]}'

To Test execute invoke/query .... everytime invoke is called value will increment by 10 9. Execute invoke chain.sh invoke 10. Execute query chain.sh query

Solution to exercise

1. Solution is in the delstate.go

2. Add the following to the invoke function // Solution to the exercise else if(funcName == "delete"){

    // Delete the token
    return DeleteToken(stub)
   

   }

Testing the Solution

PS: You may use it with original version of the token/v5 but keep in mind that the last step will FAIL which is fine as the "delete" function is not supported by the original token/v5 implementation

Using the test.sh file

The test may be run net & dev mode. Prior to running the test install & instantiate the chaincode

1. Launch the setup in net mode dev-init.sh

2. Set the org context . set-env.sh acme

3. Set the chaincode env set-chain-env.sh -n token -v 1.0 -p token/v5 set-chain-env.sh -i '{"args":["set"]}' -q '{"args":["get"]}'

4. Install & Instantiate chain.sh install -p

   set-chain-env.sh -c '{"args":[]}' chain.sh instantiate

5. Launch the test chain.sh query chain.sh invoke

6. Delete & Test again chain.sh query
