我正在以太坊学习智能合约编程,我和松露一起工作。现在我在这里做这个教程: https://truffleframework.com/tutorials/building-dapps-for-quorum-private-enterprise-blockchains

学习如何创建具有仲裁的DAPP。但现在我有个问题。

我做的每件事都和描述的一样,但当我做的时候:

truffle migrate

我在这里得到这个错误:

    Truffle v5.0.1 (core: 5.0.1)
    Node v8.11.4

现在我不知道为什么…

有没有人有同样的问题可以帮我解决?

这是我的智能合约:

pragma solidity ^0.4.17;

contract SimpleStorage {
  uint public storedData;

  constructor(uint initVal) public {
    storedData = initVal;
  }

  function set(uint x) public {
    storedData = x;
  }

  function get() view public returns (uint retVal) {
    return storedData;
  }
}

我的truffle-config.js文件:

module.exports = {
  networks: {
    development: {
      host: "127.0.0.1",
      port: 22000, // was 8545
      network_id: "*", // Match any network id
      gasPrice: 0,
      gas: 4500000
    },
    nodefour:  {
      host: "127.0.0.1",
      port: 22003,
      network_id: "*", // Match any network id
      gasPrice: 0,
      gas: 4500000
    },
    nodeseven:  {
      host: "127.0.0.1",
      port: 22006,
      network_id: "*", // Match any network id
      gasPrice: 0,
      gas: 4500000
    }
  },
  // Set default mocha options here, use special reporters etc.
  mocha: {
    // timeout: 100000
  },

  // Configure your compilers
  compilers: {
    solc: {
      version: "0.4.25",    // Fetch exact version from solc-bin (default: truffle's version)
    }
  }
}

以及迁移文件:

var SimpleStorage = artifacts.require("SimpleStorage");

module.exports = function(deployer) {
  // Pass 42 to the contract as the first constructor parameter
  deployer.deploy(SimpleStorage, 2, { privateFor: ["ROAZBWtSacxXQrOe3FGAqJDyJjFePR5ce4TSIzmJ0Bc="] })
};

所以问题是块时间戳是以纳秒为单位的。

@Edgraaff写了一个代理,它将时间戳从纳秒转换为秒。您可以在此处找到代码-> https://github.com/edgraaff/quorum-rpc-proxy

我要做的是克隆代理并将config.js文件更改为:

module.exports = {
  rpcUrl: 'http://localhost:22000',
  port: 7545
};

在truffle-config.js文件中,我必须更改端口。代码如下:

module.exports = {
  networks: {
    development: {
      host: "127.0.0.1",
      port: 7545, // was 8545
      network_id: "*", // Match any network id
      gasPrice: 0,
      gas: 4500000
    },
    nodefour:  {
      host: "127.0.0.1",
      port: 22003,
      network_id: "*", // Match any network id
      gasPrice: 0,
      gas: 4500000
    },
    nodeseven:  {
      host: "127.0.0.1",
      port: 22006,
      network_id: "*", // Match any network id
      gasPrice: 0,
      gas: 4500000
    }
  },
  // Set default mocha options here, use special reporters etc.
  mocha: {
    // timeout: 100000
  },

  // Configure your compilers
  compilers: {
    solc: {
      version: "0.4.25",    // Fetch exact version from solc-bin (default: truffle's version)
    }
  }
}

@QuorumPrivateBlockchain嘿,伙计。

这是我的truffle-config.js文件:

module.exports = {
  networks: {
    development: {
      host: "127.0.0.1",
      port: 7545,
      network_id: "*",
      gasPrice: 0,
      gas: 4500000
    },
    nodefour:  {
      host: "127.0.0.1",
      port: 7546,
      network_id: "*",
      gasPrice: 0,
      gas: 4500000
    },
    nodeseven:  {
      host: "127.0.0.1",
      port: 7547,
      network_id: "*",
      gasPrice: 0,
      gas: 4500000
    }
  },
  compilers: {
    solc: {
      version: "0.4.25",   
    }
  }
}

这是代理服务器上的config.js文件:

module.exports = [
  {
    rpcUrl: 'http://localhost:22000',
    port: 7545
  },
  {
    rpcUrl: 'http://localhost:22003',
    port: 7546
  },
  {
    rpcUrl: 'http://localhost:22006',
    port: 7547
  },
];

所以,您要做的是,将来自truffle的请求发送到代理服务器,然后代理服务器转换时间戳并将请求进一步发送到节点。

代理本身就是一个程序,您不必从代理代码中复制config.js文件。看看Github如何启动代理。

代理是不够的,因为web3.js可以通过ws在subscription中获取块

同样,在按编号获取块的仲裁中,它只接受十六进制,但是web3.js假定十六进制为blockhash

这是我的解决方案

web3.extend({
  property: 'eth',
  methods: [new web3.extend.Method({
    name: 'getBlockByNumber',
    call: 'eth_getBlockByNumber',
    params: 2,
    inputFormatter: [web3.extend.formatters.inputBlockNumberFormatter, v => !!v],
    outputFormatter: web3.extend.formatters.outputBlockFormatter
  })]
});
web3.utils.hexToNumber = v => {
  if (!v) return v;
  try {
    return numberToBN(v).toNumber();
  } catch (e) {
    return numberToBN(v).toString();
  }
};

现在注意时间戳是字符串

这是web3.js repo中的相关问题 https://github.com/ethereum/web3.js/issues/1215
