检查ganache-cli中的事务

Question

是否有命令进入终端以检查本地部署的ganache-cli块链上的过去事务？使用加纳奇桂，可以获取事务按钮。对于ganache-cli是否有类似的功能，还是必须滚动？提前感谢

Answer 1

您可以使用松露控制台和web3-eth API：

# connect to 'development' network
truffle console

获取最新事务的日志：

truffle(development)> await web3.eth.getPastLogs({})
[
  {
    logIndex: 0,
    transactionIndex: 0,
    transactionHash: '0x8d550f02c2ad9ce0770100ea35fddcb4239605338904999bac0b44ab98d47469',
    blockHash: '0x51cfc9b9fb563729ea9791258d172e2d7e15526fa39df3cc8002d8c1e124b023',
    blockNumber: 14,
    address: '0xc8474d35f43c485A193f4619AD5dfc13E6Ef7670',
    data: '0x0000000000000000000000000000000000000000000000000000000000000000',
    topics: [
      '0x6c0fa476682fe2e95bf3de06aae1b1660cd12883277ff64b03496b5e1a7d08dd',
      '0x000000000000000000000000000000000000000000000000000000006047e03d',
      '0x000000000000000000000000000000000000000000000000000000006047e040',
      '0x000000000000000000000000000000000000000000000000000000006047e041'
    ],
    type: 'mined',
    id: 'log_320edfe0'
  }
]

获取第n块中第n次事务的信息：

# get info about the first transaction on the 14th block

truffle(development)> await web3.eth.getTransactionFromBlock(14, 0)
{
  hash: '0x8d550f02c2ad9ce0770100ea35fddcb4239605338904999bac0b44ab98d47469',
