require_auth() not working as expected

Question

I adapted the hello contract, expanding with require_auth() and added an additional account oliver that should be able to execute the action hashin on behalf of the contract owner doctest1. I adjusted the permission within the account doctest1.

When I try to push action hashin, I get an error:

cleos push action doctest1 hashin '["oliver"]' -p oliver@active


Error 3090004: Missing required authority
Ensure that you have the related authority inside your transaction!;
If you are currently using 'cleos push action' command, try to add the relevant authority using -p option.
Error Details:
missing authority of active
pending console output:


my contract looks like this:

 #include "../include/doctest1.hpp" 

ACTION doctest1::hi(name nm) {   print_f("Name : %\n", nm); }

ACTION doctest1::check(name nm) {
   print_f("Name : %\n", nm);
   eosio::check(nm == "doctest1"_n, "check name not equal to `doctest1`");
 }

  ACTION doctest1::hashin(std::string h) {
   require_auth(_self);
   print_f("my hash: %", h.c_str());
 }

 EOSIO_DISPATCH(doctest1, (hi)(check)(hashin))


doctest1 account permission:

What do I need to adjust so doctest1 account can serve as a group of accounts (growing with accounts that need to execute hashin)?

Answer 1

If several users need to be able to use this function, but they have to authorize themselves to use it, then you would write your function as follows:

ACTION doctest1::hashin(eosio::name user, std::string h){
  require_auth(user);
  print_f("my hash: %", h.c_str());
}

Then the user would call the function as follows:

cleos push action doctest1 hashin '["oliver","oliver"]' -p oliver@active

Answer 2

you have put the "require_auth(_self);" , that means the action will be only executed by the deployed contract account. The keyword "_self" allow only one account which is the name of the deployed contract account. If u want to push that action with ur oliver account just comment the line "require_auth(_self);"
