完整的区块链坚固课程第7课：未知功能或类型＆＃x27; gasleft＆＃x27;
下面的功能是在调用gasleft（）和（bool成功）时抛出“未知函数或类型错误”。
function callBackWithRandomness(
bytes32 requestId,
uint256 randomness,
address consumerContract
) public {
VRFConsumerBase v;
bytes memory resp = abi.encodeWithSelector(v.rawFulfillRandomness.selector, requestId, randomness);
uint256 b = 206000;
require(gasleft() >= b, "not enough gas for consumer");
(bool success,) = consumerContract.call(resp);
}
谢谢
the function below is throwing an "unknow function or type error" when calling gasleft() and (bool success) is not being read.
function callBackWithRandomness(
bytes32 requestId,
uint256 randomness,
address consumerContract
) public {
VRFConsumerBase v;
bytes memory resp = abi.encodeWithSelector(v.rawFulfillRandomness.selector, requestId, randomness);
uint256 b = 206000;
require(gasleft() >= b, "not enough gas for consumer");
(bool success,) = consumerContract.call(resp);
}
thank you

Hi DorianDaSilva
Can you confirm that you've followed the addenda/udpates from this README regarding Lesson 7? Specifically, that you're using a VRF V1 contract address?
