Solidity function 在混音中返回真，但在 web3 function 调用中返回假

Question

I have this Solidity function, it is returning the right answer when called in remix IDE but in web3 call, it is returning false always

function checkSubscribed() public view returns(bool){
        if(block.timestamp>subscriptionPeriod[msg.sender]){
            return false;
        }
        else{
             return true;
        }
     
    }

My web3 call function(version 1.2.9)

myContract.methods.checkSubscribed().call({from:userAccount},(err,status)=>{
   console.log(status);

});

Answer 1

Check subscriptionPeriod[msg.sender] and block.timestamp .

If you don't know where to look at the timestamp value, just add a debug method to the contract:

function timestamp() external view returns (uint256) {
  return block.timestamp;
}
