使用 decodeparameters 函数 解析币安链的 Transaction 日志数据

查看日志的时候，你会发现数据是加密的。

 let ss1 = `0x00000000000000000000000000000000000000000000000093845de66b9a30fe000000000000000000000000000000000000000000000000000e35fa931a00000000000000000000000000000000000000000000000000330ca85aa35d0afe280000000000000000000000000000000000000000000000000000000000000000`;

        console.log('web3', web3.eth.abi.decodeParameters([{
            type: 'uint256',
            name: 'amount0In'
        },{
            type: 'uint256',
            name: 'amount1In'
        },{
            type: 'uint256',
            name: 'amount0Out'
        },{
            type: 'uint256',
            name: 'amount1Out'
        }], ss1 ));

他这个数据结构需要你去定义。

得到结果：

web3 Result {
  '0': '106297242730341630',
  '1': '4000000000000000',
  '2': '941696026341416828456',
  '3': '0',
  __length__: 4,
  amount0In: '106297242730341630',
  amount1In: '4000000000000000',
  amount0Out: '941696026341416828456',
  amount1Out: '0'
}
