Can we find the endorser details in smart contract during execution(Hyperledger Fabric)?

Question

我们可以在执行期间在智能合约中找到背书者的详细信息（Hyperledger Fabric）吗？

Answer 1

Check out the below link, by using this library you access MSPid, fabric-ca certificate details inside the chaincode

https://github.com/hyperledger/fabric-chaincode-go/blob/main/pkg/cid/README.md

https://hyperledger-fabric.readthedocs.io/en/release-2.2/endorsement-policies.html

https://github.com/hyperledger/fabric-samples/blob/main/asset-transfer-secured-agreement/chaincode-go/asset_transfer.go

Answer 2

If you use the internal docker build mechanism then the only thing available to chaincode is CORE_PEER_LOCALMSPID

I've not tried but if you use an external builder you could add more information yourself during the run part see https://hyperledger-fabric.readthedocs.io/en/release-2.2/cc_launcher.html?highlight=builder#external-builder-and-launcher-api

and if you use chaincode as a service then it may be possible for you to bake something into the image you use in different orgs
