像这样：

const SwapABI = ["event Swap(address indexed sender,uint amount0In,uint amount1In,uint amount0Out,uint amount1Out,address indexed to)"];

  const swapEvent = new ethers.utils.Interface(SwapABI);

  swapData = swapEvent.parseLog(logs)     

 swapData.args.amount0In.toString()
 swapData.args.amount1Out.toString()
