如何在一个链码中部署多个合约（Hyperledger Fabric）答案

【问题标题】：How to deploy multiple contracts in one chaincode(Hyperledger fabric)如何在一个链码中部署多个合约（Hyperledger Fabric）

【问题描述】：

我使用fabric-contractapi-go 编写我的链码，这个链码包含两个合约。我已经在fabric-chaincodedev-mode 中对其进行了测试。但是当我使用这样的命令在fabric-firstnetwork中部署它时，无论是在命令行中还是在fabric-gateway-sdk-java中，我都无法获得第二个合约。

#package
docker exec cli peer lifecycle chaincode package helloworld.tar.gz \
--path github.com/hyperledger/fabric-samples/chaincode/helloworld/go/ \
--label helloworld_1

#install in two orgs
docker exec cli peer lifecycle chaincode install helloworld.tar.gz

如果你知道了，请告诉我！

【解决方案1】：

在你的链码中

func main () {
  contracts := []contractapi.ContractInterface{&contract.A{}, &contract.B{}}
  yourChaincode, _ := contractapi.NewChaincode(contracts...)
  if err := yourChaincode.Start();err!=nil{
    log.Panicf("Error starting chaincode: %v",err) 
  }
}

在您的应用程序中，您可以将其用作

contractA := network.GetContractWithName("yourChaincodeName","contractA")
contractB := network.GetContractWithName("yourChaincodeName","contractB")

“yourChaincodeName”是您在频道中部署链码时使用的名称
