关于合约某些方法开关的使用

`// SPDX-License-Identifier: MIT<br /> pragma solidity ^0.8.9;<br /> contract lockFunction{<br /> address private owner;<br /> bool private openFunction = true;<br /> uint num=1;</p> <p> /// @custom:oz-upgrades-unsafe-allow constructor<br /> constructor() {<br /> owner = payable(msg.sender);<br /> }<br /> //手动开启<br /> function unlock() public onlyOwner{<br /> openFunction = true;<br /> }<br /> //手动关闭<br /> function lock() public onlyOwner{<br /> openFunction = false;<br /> }</p> <p> function getNumber(string memory thisThing)public view returns(string memory){<br /> require(openFunction,"close");<br /> string memory setRecord = thisThing;<br /> return setRecord;<br /> }</p> <p> modifier onlyOwner() {<br /> require(isOwner());<br /> _;<br /> }</p> <p> function isOwner() internal view returns (bool) {<br /> return msg.sender == owner;<br /> }<br /> }`</p> <p>之前提问过这个问题，特地为各位做个总结，`require(openFunction,"close");`是需要加在每个方法的第一列，记住lock需要用onlyowner，否则每个人都可以开关，这很危险

 /// @custom:oz-upgrades-unsafe-allow constructor
constructor() {
    owner = payable(msg.sender);
}
//手动开启
function unlock() public onlyOwner{
    openFunction = true;
}
//手动关闭
function lock() public onlyOwner{
    openFunction = false;
}

function getNumber(string memory thisThing)public view returns(string memory){
    require(openFunction,"close");
    string memory setRecord = thisThing;
    return setRecord;
}

modifier onlyOwner() {
    require(isOwner());
    _;
}

function isOwner() internal view returns (bool) {
    return msg.sender == owner;
}
