是否可以从Hyperledger Composer脚本文件访问GO lang链码

Question

This might seem like a weird question . But i want to know if it is possible to access a GO language chaincode installed in the peers from Composer script file .

That is in script.js file of the BNA file is it possible to access the GO Lang chaincode installed in the peers from Hyperledger Fabric side .

I want to invoke a chaincode 'mycc' from the script.js file and try to call 'mycc' functions from Composer

Any suggestions? Also an example would be good . Thanks !

Answer 1

It is possible to invoke another chaincode from a Composer transaction script. You would need to use the getNativeAPI() function. It is introduced in the Composer documentation halfway down in this document where I think the example uses the native api to access the 'current' network (chaincode).

There is an additional example in this tutorial where the getNativeAPI().invokeChaincode method is used to connect to a different Business Network.

I have not seen other examples, but this should work for connecting to other chaincodes.
