如何制作在每个合约调用中调用的 function？ – 坚固性

Question

I need to make a function that will be called each time someone called my contract. And I need to do it without using modifiers because there are many functions in my contract and I use third-party contracts.

How can I do it?

Answer 1

You can inherit third-party contracts and make a new child contract and then modify each function with a modifier you defined in the child contract, that's the only way to do.

Example:

Contract ThirdParty {
    address owner;

    function f() public {}
}


Contract Child is ThirdParty {

    modifier onlyOwner {
        require(msg.sender == owner);
        _;
    }

    function f() public onlyOwner {}
}
