在“硬帽子”节点中找不到函数选择器

Question

我试图使用getTokenDepositAmount(uint inputToken)从前端(Reactjs)调用一个智能契约，但我在浏览器控制台中得到了这个错误：

Error: call revert exception [ See: https://links.ethers.org/v5-errors-CALL_EXCEPTION ] (method="getTokenDepositAmount(uint256)", data="0x", errorArgs=null, errorName=null, errorSignature=null, reason=null, code=CALL_EXCEPTION, version=abi/5.7.0)

    at Contract.<anonymous> (index.ts:400:1)
    at Generator.next (<anonymous>)
    at fulfilled (index.ts:1:1)

在“硬帽子”节点控制台中，我得到了以下信息：

eth_call
  Contract call:       UniswapClone#<unrecognized-selector>
  From:                0xf39fd6e51aad88f6f4ce6ab8827279cfffb92266
  To:                  0x9fe46736679d2d9a65f0992f2272de9f3c7fa6e0

Smart合同功能：

function getTokenDepositAmount(uint inputToken) public view returns (uint) {
        uint256 ethReserve = address(this).balance; 
        return ((inputToken * tokenReserve) / ethReserve) + 1;
    }

我在这里没有回复语句，但是我得到了这个错误。有人能告诉我我在这里做错了什么吗？

注意:我已经在本地主机上:8545，并将其中一个帐户从“草帽”节点导入到元数据库中。

编辑

下面是我调用函数的代码：

async function fetchDepositTokenAmount() {
    console.log(contract);
    const depositAmount = await contract.getTokenDepositAmount(
      ethers.utils.parseEther("1")
    );
    console.log("deposit amount: ", depositAmount);
  }

Answer 1

你试过预先兑换金额了吗？

async function fetchDepositTokenAmount() {
    console.log(contract);
    let amount =  ethers.utils.parseEther("1");
    const depositAmount = await contract.getTokenDepositAmount(amount);
    console.log("deposit amount: ", depositAmount);
  }

现在该起作用了。希望能帮上忙
