Fabric composer tips and tricks - working with current identity

If you work with Fabric Composer, the ACL (Access Control List) language is meant to handle access rules in the system. However there might be the case that you need to define access rules directly in the smart contract code in a hard coded way. If that is the case, you can ask the current identity with the getCurrentIdentity() API call and implement the corresponding access logic based on the identity information:

 var identity = getCurrentIdentity();    


 console.log("identity namespace : " + identity);

 console.log("identity certificate : " + identity.certificate);

 console.log("identity identityId : " + identity.identityId);

 console.log("identity name : " + identity.name);

 console.log("identity participant identifier : " + identity.participant.$identifier);

 console.log("identity participant namespace : " + identity.participant.$namespace);

 console.log("identity participant type : " + identity.participant.$type);
