Saya tidak tahu sama ada ia diperlukan, tetapi saya menemui penyelesaiannya dengan cara ini. FungsitriggerConstantContract可以返回实际网络调用之前的能量消耗，但由于某种原因iexbase没有实现这样的逻辑。因此，我在TransactionBuilder.php中的public function triggerConstantContractKemudian menambah fungsi saya sendiri yang mengembalikan hasil lengkap termasuk maklumat tenaga

public function triggerConstantContractFull($abi, $contract, $function, $params = [], $address = '410000000000000000000000000000000000000000') { $func_abi = []; foreach($abi as $key =>$item) { if(isset($item['name']) && $item['name'] === $function) { $func_abi = $item + ['inputs' => []]; break; } } if(count($func_abi) === 0) throw new TronException("Function $function not defined in ABI"); if(!is_array($params)) throw new TronException("Function params must be an array"); if(count($func_abi['inputs']) !== count($params)) throw new TronException("Count of params and abi inputs must be identical"); $inputs = array_map(function($item){ return $item['type']; },$func_abi['inputs']); $signature = $func_abi['name'].'('; if(count($inputs) > 0) $signature .= implode(',',$inputs); $signature .= ')'; $eth_abi = new Ethabi([ 'address' => new Address, 'bool' => new Boolean, 'bytes' => new Bytes, 'dynamicBytes' => new DynamicBytes, 'int' => new Integer, 'string' => new Str, 'uint' => new Uinteger, ]); $parameters = substr($eth_abi->encodeParameters($func_abi, $params),2); $result = $this->tron->getManager()->request('wallet/triggerconstantcontract', [ 'contract_address' => $contract, 'function_selector' => $signature, 'parameter' => $parameters, 'owner_address' => $address, ]); if(!isset($result['result'])){ throw new TronException('No result field in response. Raw response:'.print_r($result,true)); } if(isset($result['result']['result'])) { return $result; } $message = isset($result['result']['message']) ? $this->tron->hexString2Utf8($result['result']['message']) : ''; throw new TronException('Failed to execute. Error:'.$message); } }

Jadi anda boleh melakukan sesuatu seperti ini

$transfer = $this->_tron->getTransactionBuilder() ->triggerConstantContractFull( $this->abiData, $this->_tron->address2HexString($this->contractAddress), 'transfer', [$this->_tron->address2HexString($to), $tokenAmount], $this->_tron->address2HexString($from) );
