通过test-network-k8s和chaincode service在vscode调试智能合约

概要步骤

通过fabric sample中的test-network-k8s和chaincode service在vscode调试智能合约。 合约选用fabric sample中的chaincode-external

网络配置

127.0.0.1 host.docker.internal > /etc/hosts

合约配置

{
  "address": "host.docker.internal:9999",
  "dial_timeout": "10s",
  "tls_required": false
}

启动test-network-k8s指向位于host.docker.internal:9999的合约

$ ./network up
$ ./network channel create
$ export TEST_NETWORK_CHAINCODE_NAME=asset-transfer-basic-debug
$ export TEST_NETWORK_CHAINCODE_IMAGE=localhost:5000/asset-transfer-basic

$ ./network chaincode install
Installing chaincode "asset-transfer-basic-debug":
✅ - Packaging chaincode folder chaincode/asset-transfer-basic-debug ...
✅ - Transferring chaincode archive to org1 ...
✅ - Installing chaincode for org org1 ...
 - Chaincode is installed with CHAINCODE_ID=basic_1.0:159ed2f227586f40c5804e157919903fda2b861488f35eefb365eb9d85a73da3

配置vscode启动器监听host.docker.internal:9999并且绑定合约id basic_1.0:159ed2f227586f40c5804e157919903fda2b861488f35eefb365eb9d85a73da3

    "version": "0.2.0",
    "configurations": [
        {
            "name": "Launch Package",
            "type": "go",
            "request": "launch",
            "mode": "auto",
            //"program": "${fileDirname}"
            "program": "${workspaceFolder}",
            "env": {
                "CHAINCODE_ID": "basic_1.0:a265635539e1fb9358664e124c95757d9253534902ac00f880b4eb0231613667",
                "CHAINCODE_SERVER_ADDRESS": "0.0.0.0:9999",
            },
            "args": []

        }
    ]
}

启动vscode暂停在服务启动的断点

释放vscode debug模式的断点 在test-network-k8s中发起调用

$ ./network chaincode activate 

./network chaincode invoke '{"Args":["CreateAsset","1","blue","35","tom","1000"]}' 
./network chaincode query '{"Args":["ReadAsset","1"]}'

完成（进入到业务上的断点）

提示

在本模式中，如果不及时释放vscode中的短点
会触发 合约调用超时异常
