Ropsten网络不确定

Question

我正在尝试将MetAmask上的Ropsten TestNet连接到我的项目。但是我有一个我几天无法解决的问题。我对要重定向的页面上的定义如下。

当我希望它是一个错误时，我希望它给我一条消息。我现在正好遇到这个错误。 '确保您在Corrent网络上。将网络设置为Ropsten Test Network的

publicDashboard.jsx

    useEffect(() => {
        const init = async () => {
            try {
                const web3 = await getWeb3();
                const accounts = await web3.eth.getAccounts();
                const networkId = await web3.eth.net.getId();
                const deployedNetwork = Project.networks[networkId];
                if(deployedNetwork === undefined)
                    throw new Error('Make sure you are on the corrent network. Set the network to Ropsten Test Network');
                const contract = new web3.eth.Contract(
                    Project.abi,
                    deployedNetwork.address,
                );
                setWeb3(web3);
                setAccounts(accounts);
                setContract(contract);
            } catch (error) {
                window.alert(error);
                history.push("/dashboard");
            }
        }
        init();
        if (isReady()) {
            window.ethereum.on('accountsChanged', accounts => {
                setAccounts(accounts);
            });
        }
    }, [history]);

，这是我的Truffle-config.js文件。一切似乎正常。我不明白为什么它没有连接。你能帮我吗？

const path = require("path");

const HDWalletProvider = require('@truffle/hdwallet-provider');

const fs = require('fs');
const mnemonic = fs.readFileSync(".secret").toString().trim();

module.exports = {
  
  contracts_build_directory: path.join(__dirname, "src/contracts"),
  networks: {
    ropsten: {
      provider: () => new HDWalletProvider(mnemonic, 'https://ropsten.infura.io/v3/08ac778579d74dbaa8d2e3d02e5c0092'),
      network_id: 3, // Ropsten's id
      gas: 5500000, // Ropsten has a lower block limit than mainnet
      confirmations: 2, // # of confs to wait between deployments. (default: 0)
      timeoutBlocks: 200, // # of blocks before a deployment times out  (minimum/default: 50)
      skipDryRun: false // Skip dry run before migrations? (default: false for public nets )
    },
  },

  mocha: {
    // timeout: 100000
  },

  compilers: {
    solc: {
      //version: "0.8.13",      // Fetch exact version from solc-bin (default: truffle's version)
      // docker: true,        // Use "0.5.1" you've installed locally with docker (default: false)
      // settings: {          // See the solidity docs for advice about optimization and evmVersion
      //  optimizer: {
      //    enabled: false,
      //    runs: 200
      //  },
      //  evmVersion: "byzantium"
      // }
    }
  },

 }
};

而且我还编写了终端此代码“松露迁移 - 网络ropsten”。我没有看到任何错误。

对于将来的参考，请勿发布以08AC7785开头的API密钥...这意味着任何人都可以使用它，请在可能的情况下删除API键。似乎您的项目名称空间无效。比使用HDWALLETPROVIDER更好的新解决方案是使用新的松露仪表板命令与MetAmask连接，该MetAmask连接到您的硬件钱包
