How to set SignaturePolicy for Collections

[1gezhanghao]

// Definition of a chaincode in https://github.com/hyperledger/fabric-admin-sdk/blob/main/pkg/chaincode/lifecycle.go

type Definition struct {
    ChannelName         string
    PackageID           string
    Name                string
    Version             string
    EndorsementPlugin   string
    ValidationPlugin    string
    Sequence            int64
    ValidationParameter []byte
    InitRequired        bool
    Collections         *peer.CollectionConfigPackage
}

https://github.com/hyperledger/fabric-admin-sdk/blob/main/test/e2e_test.go#L236 in this demo Collections is set to nil, nothing more.How to set a SignaturePolicy in Collections is my question

eg:the SignaturePolicy expression is "AND('Org2MSP.peer','Org1MSP.peer')" , how to set this?

[SamYuan1990]

ok, could you give me an example with peer cli then I am going to trace with the code.

[1gezhanghao]

you can find the example in https://hyperledger-fabric.readthedocs.io/en/latest/commands/peerlifecycle.html in chapter : peer lifecycle chaincode approveformyorg example

use the cmd like this

peer lifecycle chaincode approveformyorg  -o orderer.example.com:7050 --tls --cafile $ORDERER_CA --channelID mychannel --name mycc --version 1.0 --init-required --package-id myccv1:a7ca45a7cc85f1d89c905b775920361ed089a364e12a9b6d55ba75c965ddd6a9 --sequence 1 --signature-policy "AND ('Org1MSP.peer','Org2MSP.peer')"
