如何将自定义业务逻辑应用于Hyperledger上的背书策略？

// 示例链码
package main

import (
    "fmt"
    "github.com/hyperledger/fabric/core/chaincode/shim"
    "github.com/hyperledger/fabric/protos/peer"
)

type SimpleChaincode struct {
}

func (t *SimpleChaincode) Init(stub shim.ChaincodeStubInterface) peer.Response {
    return shim.Success(nil)
}

func (t *SimpleChaincode) Invoke(stub shim.ChaincodeStubInterface) peer.Response {
    function, args := stub.GetFunctionAndParameters()
    if function == "invoke" {
        // 业务逻辑处理
        return shim.Success([]byte("Invoke successful"))
    }
    return shim.Error("Invalid function name")
}

func main() {
    err := shim.Start(new(SimpleChaincode))
    if err != nil {
        fmt.Printf("Error starting SimpleChaincode: %s", err)
    }
}

peer chaincode deploy -p path/to/chaincode -c '{"function":"init","args":["arg1","arg2"]}' -P "AND('Org1MSP.member','Org2MSP.member')"
