处理事务时的vm异常: gas外

Question

我已经用同样的错误阅读了其他的主题，但这并没有解决我的问题.

当我试图与我的智能契约在web接口之间进行测试rpc通信时，我总是出错“处理事务时的vm异常: out of gas"，而当我的智能契约中只有4个输入时，就没有问题了。

我已经尝试使用它来启动tesrpc (因为只有没有工作的testrpc )：

--account="0x7231a774a538fce22a329729b03087de4cb4a1119494db1c10eae3bb491823e7,10000000000000000000“

介电常数-l 4500000000000

测试--汽油价格20000

介电常数-g 1000000000000000

不管我用的是什么，气体使用量保持在90000，我认为错误与此有关……感谢帮助我的人！

这是我的合同：

       x1 = _x1;
       x2 = _x2;

抱歉我的ABI太长了..。

Answer 1

SendCoin方法将消耗102912个单元。我建议您使用estimateGas()函数。它将返回给定输入的气体消耗量。

请参阅以下修改的代码：

    $("#button").click(function() {
        var _gas = URP.SendCoin.estimateGas($("#x1").val(), $("#x2").val(), $("#y1").val(), $("#y2").val(), $("#z1").val(), $("#z2").val(), $("#retailer").val(), $("#value").val(), $("#x").val(), $("#y").val(), $("#z").val(), $("#shopper").val());
        _gas = Math.floor(gas*1.2); //For safe side.
        URP.SendCoin($("#x1").val(), $("#x2").val(), $("#y1").val(), $("#y2").val(), $("#z1").val(), $("#z2").val(), $("#retailer").val(), $("#value").val(), $("#x").val(), $("#y").val(), $("#z").val(), $("#shopper").val(), {from:'your account', gas:_gas});
    });

我建议您使用异步方法的. MetaMask不会执行同步方法。

试试testrpc --gas-limit 4600000。

请记住，testrpc已改为ganache-cli。我运行ganache-cli --gas-limit 4600000

另外，确保配置了您的truffle.js。你可以改变汽油价格和汽油价格。

networks: {
    development: {
        host: "localhost",
        port: 8545,
        network_id: "0",
        gas: 10000000,
        gasLimit: 10000000
    },
 }
