Test chaincode

You can go to the playground(instead of /graphql, use /playground) and use the following mutation and query to test the chaincode:

mutation invoke {
  invokeChaincode(input:{
    chaincodeName:"template_go"
    function: "InitLedger"
    args: []
    transientMap: []
  }){
    response
    transactionID
    chaincodeStatus
  }
}

mutation query {
  queryChaincode(input:{
    chaincodeName:"template_go"
    function: "GetAllAssets"
    args: []
    transientMap: []
  }){
    response
    chaincodeStatus
  }
}
