[root@localhost chaincode-go]# GO111MODULE=on go mod vendor
[root@localhost chaincode-go]# cd ../../test-network-myself安装依赖后将出现vendor目录 ，如下图：
打包链码
[root@localhost test-network-myself]# peer lifecycle chaincode package ${CC_NAME}.tar.gz --path ${CC_SRC_PATH} --lang ${CC_RUNTIME_LANGUAGE} --label ${CC_NAME}_${CC_VERSION}
打包完成将生成打包文件，如下图：

查询组织2中peer节点安装链码的链码包ID
在组织1与组织2中安装链码的链码包ID是一样的，因此在一个组织中查看即可
[root@localhost test-network-myself]# peer lifecycle chaincode queryinstalled >&log.txt
[root@localhost test-network-myself]# export PACKAGE_ID=$(sed -n "/${CC_NAME}_${CC_VERSION}/{s/^Package ID: //; s/, Label:.*$//; p;}" log.txt)

调用链码函数
当前是调用的是组织2中的peer节点
设置初始资产
[root@localhost test-network-myself]# peer chaincode invoke -o localhost:7050 --ordererTLSHostnameOverride orderer.example.com --tls --cafile ${PWD}/organizations/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem -C mychannel -n basic ${PEER_CONN_PARMS[@]} -c '{"function":"InitLedger","Args":[]}'
2021-11-26 21:12:58.719 CST [chaincodeCmd] chaincodeInvokeOrQuery -> INFO 001 Chaincode invoke successful. result: status:200
查询所有资产
[root@localhost test-network-myself]# peer chaincode query -C mychannel -n basic -c '{"Args":["GetAllAssets"]}'
[{"AppraisedValue":300,"Color":"blue","ID":"asset1","Owner":"Tomoko","Size":5},{"AppraisedValue":400,"Color":"red","ID":"asset2","Owner":"Brad","Size":5},{"AppraisedValue":500,"Color":"green","ID":"asset3","Owner":"Jin Soo","Size":10},{"AppraisedValue":600,"Color":"yellow","ID":"asset4","Owner":"Max","Size":10},{"AppraisedValue":700,"Color":"black","ID":"asset5","Owner":"Adriana","Size":15},{"AppraisedValue":800,"Color":"white","ID":"asset6","Owner":"Michel","Size":15}]
调用的是组织1中的peer节点查询所有资产
[root@localhost test-network-myself]# export CORE_PEER_LOCALMSPID="Org1MSP"
[root@localhost test-network-myself]# export CORE_PEER_TLS_ROOTCERT_FILE=$PEER0_ORG1_CA
[root@localhost test-network-myself]# export CORE_PEER_MSPCONFIGPATH=${PWD}/organizations/peerOrganizations/org1.example.com/users/[email protected]/msp
[root@localhost test-network-myself]# export CORE_PEER_ADDRESS=localhost:7051

在组织1与组织2的peer节点中查询的数据是一样的。此链码中还有一些转资产，查询个人资产操作，在这里就不演示啦。
