部署到Goerli测试网后出错

Question

我在fleek.co上托管了我的彩票网站，一切都很好，而在草帽本地网络上。所以我决定在Goerli上测试它，我面临着一个又一个错误。

首先，我得到了下面的错误1，并手动添加了一个气体限制在硬帽子配置文件。在重新部署合同并在fleek上发布之后，最初，enterRaffle可以正常工作。

当我第二次尝试enterRaffle时，它失败了。其他时候是成功的。但即便如此，它也不会像预期的那样更新球员的数量。

我错过了什么？

错误1

Error: cannot estimate gas; transaction may fail or may require manual gas limit [ See: https://links.ethers.org/v5-errors-UNPREDICTABLE_GAS_LIMIT ] (error={"code":-32603,"message":"execution reverted","data":{"originalError":{"code":3,"data":"0x1425571c","message":"execution reverted"}}}, method="estimateGas", transaction={"from":"0x13A19933267ec307c96f3dE8Ff8A2392C39263EB","to":"0x5507C7e274B5201a98141cCd0507cF6e4416Be30","value":{"type":"BigNumber","hex":"0x2386f26fc10000"},"data":"0x2cfcc539","accessList":null}, code=UNPREDICTABLE_GAS_LIMIT, version=providers/5.6.0)

    at Generator.throw (<anonymous>)
    at s (_app-3ca186e4a2557e86.js:1:2114235)

然后在像这样手动添加气体之后，就会出现错误2。

        goerli: {
            url: GOERLI_RPC_URL,
            accounts: PRIVATE_KEY !== undefined ? [PRIVATE_KEY] : [],
            //   accounts: {
            //     mnemonic: MNEMONIC,
            //   },
            saveDeployments: true,
            chainId: 5,
            gas: 6000000,
        },

Answer 1

忘了在这里写更新。所以，我注意到了一些事情

问题在于ABI。

当我部署时，hh deploy --network goerli abi如下所示(这很好)

{
        "type": "function",
        "name": "getNumWords",
        "constant": true,
        "stateMutability": "pure",
        "payable": false,
        "inputs": [],
        "outputs": [{ "type": "uint256" }]
    },

当我退出我的本地草帽节点，并再次旋转它，‘hh node abi (在常量文件夹中)，更新到这个；(这是加注气田的地方)；

{
        "type": "function",
        "name": "getLastestTimeStamp",
        "constant": true,
        "stateMutability": "view",
        "payable": false,
        "gas": 29000000,           // here
        "inputs": [],
        "outputs": [{ "type": "uint256" }]
    },

我不知道为什么重新运行节点会改变abi，但是在使用正确的ABI运行之后，一切都正常。

Answer 2

在我看来，它与枚举有关-它不会将其状态重置为OPEN (我看到这发生在实际的随机词()函数中)。

我的两个建议：

1. 确保合同链接到有足够测试链接的订阅。
2. 在第154行，您也可以尝试将randomWords号与modulo.In fullfillRandomWords()函数相舍五入，将其更改为：

       uint256 indexOfWinner = (randomWords[0] % s_players.length)*1 ;

我希望这能帮上忙。

Answer 3

气体估计是通过实际运行代码来完成的。如果代码出现错误，应用程序就无法估计气体。即使您手动设置gas并仍然调用该函数，这一次它也将在evm上工作，并且仍然是一个失败的事务。

在您的情况下，如果应用程序在调用enterRaffle时给出“错误:无法估计气体”，那么如果RaffleState在调用时没有打开，或者数量小于i_enteranceFee。
