php调用智能合约报错
Fatal error: Uncaught InvalidArgumentException: Please make sure you have put all function params and callback. in D:\wwwroot\NFTtest\vendor\sc0vu\web3.php\src\Contract.php:561 Stack trace: #0 D:\wwwroot\NFTtest\1.php(28): Web3\Contract->send('transfer', '0x6669867D746ba...', Array, Object(Closure)) #1 {main} thrown in D:\wwwroot\NFTtest\vendor\sc0vu\web3.php\src\Contract.php on line 561
请问这样有什么问题吗? 为什么会回调报错呢?
