可能跟 token的decimals有关。需要具体看下，token0，token1，reserve0，reserve1的值。 ``` function getPrice() public view returns (uint256 price, uint112 reserve0, uint112 reserve1) { ISwapPair pair = ISwapPair(swapPair); (reserve0, reserve1, ) = pair.getReserves(); require(reserve1 > 0, "Reserve1 must be greater than zero"); return (getAmountOut(1 ether, reserve0, reserve1), reserve0, reserve1); } function getAmountOut(uint256 amountIn, uint reserveIn, uint reserveOut) public pure returns (uint amountOut) { require(amountIn > 0, "INSUFFICIENT_INPUT_AMOUNT"); require(reserveIn > 0 && reserveOut > 0, "INSUFFICIENT_LIQUIDITY"); uint amountInWithFee = amountIn * 990; uint numerator = amountInWithFee * reserveOut; uint denominator = (reserveIn * 1000) + amountInWithFee; amountOut = numerator / denominator; } ```
