Error: Returned error: VM Exception while processing transaction: out of gas

Error: Returned error: VM Exception while processing transaction: out of gas

我使用 migrate 在本地 truffle env 上部署了一个简单的智能合约。我正在使用 react-components 包来处理智能合约。

所以我的问题是简单的 getter 和 setter 正在工作,但是当我尝试 运行 一个带有 2-3 个参数的方法时,我得到了这个异常。

我的truffleconfig如下:

module.exports = {
  // See <http://truffleframework.com/docs/advanced/configuration>
  // to customize your Truffle configuration!
  contracts_build_directory: path.join(__dirname, "app/src/contracts"),
  networks: {
    develop: { // default with truffle unbox is 7545, but we can use develop to test changes, ex. truffle migrate --network develop
      host: "127.0.0.1",
      port: 8545,
      network_id: "*",
      gas: 6921975,
      gasPrice: 25000000000
    }
  },
  solc: {
        optimizer: {
            enabled: true,
            runs: 200
        }
    }
};

在我的 React 组件中,我这样调用:

  <div className="section">
    <h2>Testing Poni</h2>
    <p>
      This is a initial test to create Poni
    </p>
    <p>
      <strong>Stored Value: </strong>
      <ContractData
        drizzle={drizzle}
        drizzleState={drizzleState}
        contract="PoniOwnership"
        method="getMyPonies"
      />
    </p>
    <ContractForm drizzle={drizzle} contract="PoniOwnership" method="createPoni" />
  </div>

我的solidity函数是这样的:

function createPoni(string memory _code, string memory _imgLink) public onlyOwner poniIsUnique(_code){

    uint randDna = _generateRandomDna(_code);

    //!!pass imgHash here also later
    _createPoni(_code, _imgLink, randDna);
  }

function _createPoni(string memory _code, string memory _imgLink, uint _dna) private {

    uint id = ponies.push(Poni(msg.sender, _code, _imgLink, _dna, 0, true)) - 1;

    poniToOwner[id] = msg.sender;
    codeToId[_code] = id;
    ownerPoniCount[msg.sender] = ownerPoniCount[msg.sender].add(1);

    emit NewPoni(id, _code, _imgLink, _dna);
  }

struct Poni {
    address owner;
    string code;
    string imgLink;
    uint dna;
  }

我已经尝试从毛毛雨反应组件中额外发送气体,因为这里给出了选项:https://www.trufflesuite.com/docs/drizzle/react/react-components,但它会抛出错误,说功能不可支付。我不知道如何处理这个异常。

您想为交易设置更高的 gas

您想调整 ContractForm 组件上的 sendArgs({gas:})。
