未在Goerli网络上创建NFT

Question

我试图使用以下3部分教程启动nft：https://ethereum.org/en/developers/tutorials/how-to-write-and-deploy-an-nft/

我一直跟踪到课程的第三部分，但是当我去那里的时候，以太扫描页面并没有显示TokenID或contractID。

以下是我的薄荷-nft代码：

require("dotenv").config()
const API_URL = process.env.API_URL
const PUBLIC_KEY = process.env.PUBLIC_KEY
const PRIVATE_KEY = process.env.PRIVATE_KEY

const { createAlchemyWeb3 } = require("@alch/alchemy-web3")
const web3 = createAlchemyWeb3(API_URL)

const contract = require("../artifacts/contracts/MyNFT.sol/MyNFT.json")
const contractAddress = "0x81c587EB0fE773404c42c1d2666b5f557C470eED"
const nftContract = new web3.eth.Contract(abi, contractAddress)

async function mintNFT(tokenURI) {
  const nonce = await web3.eth.getTransactionCount(PUBLIC_KEY, "latest") //get latest nonce

  //the transaction
  const tx = {
    from: PUBLIC_KEY,
    to: contractAddress,
    nonce: nonce,
    gas: 500000,
    data: nftContract.methods.mintNFT(PUBLIC_KEY, tokenURI).encodeABI(),
  }

  const signPromise = web3.eth.accounts.signTransaction(tx, PRIVATE_KEY)
  signPromise
    .then((signedTx) => {
      web3.eth.sendSignedTransaction(
        signedTx.rawTransaction,
        function (err, hash) {
          if (!err) {
            console.log(
              "The hash of your transaction is: ",
              hash,
              "\nCheck Alchemy's Mempool to view the status of your transaction!"
            )
          } else {
            console.log(
              "Something went wrong when submitting your transaction:",
              err
            )
          }
        }
      )
    })
    .catch((err) => {
      console.log("Promise failed:", err)
    })
}

mintNFT("ipfs://QmQgvyZRVBQeDHBP6zLPvvjDy6f9QBSCkrrzSF7H8K7wgx")

请帮帮忙

我刚刚检查了您在Goerli contractAddress = "0x81c587EB0fE773404c42c1d2666b5f557C470eED"上使用的合同地址，它看起来不像合同，而是EOA。

检查以上钱包的tx。您可能需要的合同地址是：0x3A632C370dFE7d32F74Da5A84b7e72571bD6Da7C，但我还没有测试它。

希望它对社会有帮助和欢迎！
