require_auth for custom role

Question

Some of my action require a special role "admin". What is the best way to handle set some user as admin and some action require the users with admin role? (In solidity, I can have a setAdmin() function and modifier requireAdmin().)

Answer 1

You can use the require_auth2() function, which can check a custom permission

Verifies that name exists in the set of provided auths on a action. Throws if not found

Parameters

• name - name of the account to be verified

• permission - permission level to be verified

The official docs have an article explaining permissions in EOSIO, and you can create and manage new permissions using $ cleos set account permission
