语境

我按照7nodes的示例安装了一个仲裁网络。在节点 1 中，我私下部署了一个智能合约，将其公钥"BULeR8JyUWhiuuCMU/HLA0Q5pzkYT+cHII3ZKBey3Bo="以私有形式。

我的目标是转移到这个智能合约，执行它的功能之一。作为私人合同，转让必须签署。

所有这些都来自 nodejs 服务器。

代码

智能合约如下：

pragma solidity ^0.4.19;

contract SimpleStorage {
  uint storedData;
  uint secondData;
  uint TData;
  function set(uint x) external {
    storedData = x;
  }
  function setSecond(uint x) external {
    secondData = x;
  }
  function setT(uint x) external {
    TData = x;
  }
  function get() external view returns (uint retVal) {
    return storedData;
  }
  function getSecond() external view returns (uint retVal) {
    return secondData;
  }
  function getT() external view returns (uint retVal) {
    return TData;
  }
}

nodejs中的代码如下：

const Web3 = require('web3');
const EthereumTx = require('ethereumjs-tx');
const contract = require('truffle-contract');
const simpleStorageInterface = require("./contracts/SimpleStorage.json");
var web3 = new Web3(
    new Web3.providers.HttpProvider('http://172.10.4.159:22000')
);

问题和问题

交易执行成功，但智能合约中的新值“123”没有改变。仅当我在交易await web3.eth.personal.unlockAccount (account, "")真正起作用之前解锁帐户，但出于安全原因我不想阻止和解锁帐户。

正确的转移如下：

{
  blockHash: "0xe5a2df3f592392c71f9995d697721c046f60c81d2988418b0c7b929cb17a0cee",
  blockNumber: 2190,
  from: "0xed9d02e382b34818e88b88a309c7fe71e65f419d",
  gas: 90000,
  gasPrice: 0,
  hash: "0x24df9e01d9fdb7acc7a2842dcdd1d93a37e7be7885ef469a262d8a690f7143f3",
  input: "0xb0101ef545cf42bb490bca4fac873ea06d989abf1fbdc89f7dfd09014c085f163c371efa5acac2b43c9dec5cb20bd11e853069a99f4bcb938d6fdcd6f2918333",
  nonce: 31,
  r: "0x9851006a766b4bd75051cdba9c06b6d251125d68894983eee3a4c1a53a03d77a",
  s: "0x1696039cedf14a82147c858bc17896664c9c74bda313307dbf9386b7d6893938",
  to: "0x1932c48b2bf8102ba33b4a6b545c32236e342f34",
  transactionIndex: 0,
  v: "0x25",
  value: 0
}

我的看起来像这样：

{
  blockHash: "0x6a2aacceabe984b2c368fa9ca7c245065924dd6d88e30f81311e2a5a7e2aeab8",
  blockNumber: 2119,
  from: "0xed9d02e382b34818e88b88a309c7fe71e65f419d",
  gas: 2000000,
  gasPrice: 0,
  hash: "0x4a918c1641478c1f229e7cdfff93669a6e08b37555eafe871fc3b05717cbcb79",
  input: "0x60fe47b1000000000000000000000000000000000000000000000000000000000000007b",
  nonce: 30,
  r: "0xac64a34de4bf0c2d3f1d8da6af3d38ee12be38846f744004eeef460ad94b528e",
  s: "0x10e642925665877c4e2571a2f835af68c025417574462ffc4864e6128e4a4deb",
  to: "0x1932c48b2bf8102ba33b4a6b545c32236e342f34",
  transactionIndex: 0,
  v: "0x1c",
  value: 0
}

不同之处在于属性“v”，在我的转移中固定的值不正确，它必须是 0x25 或 0x26 才能将它们标识为私人转移。我不明白为什么这些值设置不好，请帮帮我。
