Blockchain Solidity在移除uniswap流动性时获得eth金额

因此，我正在从ERC20>ETH池中移除一些流动性，但我想存储移除流动性时获得的ETH金额

function removeETHLiquidityFromToken() public {

// approve token
IERC20(tokenAddressLP).approve(UNISWAP_ROUTER_ADDRESS, IERC20(tokenAddressLP).balanceOf(address(this)));

// remove liquidity
uniswapRouter.removeLiquidityETH(tokenAddress, IERC20(tokenAddressLP).balanceOf(address(this)), 0, 0, address(this), now + 20);

// I want to use the ETH value later in this function

}

这样做效果很好，它消除了流动性

function removeETHLiquidityFromToken() public {

// approve token
IERC20(tokenAddressLP).approve(UNISWAP_ROUTER_ADDRESS, IERC20(tokenAddressLP).balanceOf(address(this)));

// remove liquidity
uniswapRouter.removeLiquidityETH(tokenAddress, IERC20(tokenAddressLP).balanceOf(address(this)), 0, 0, address(this), now + 20);

// I want to use the ETH value later in this function

}

但是我怎样才能得到那个量的乙醚，这样我以后就可以用它了

该函数返回两个值<代码>外部返回（uint amountToken、uint amountth）

因此，您可以识别接收到的

uint

并按如下方式分配返回给它的第二个uint：

( ,ethReceived) = uniswapRouter.removeLiquidityETH(tokenAddress, IERC20(tokenAddressLP).balanceOf(address(this)), 0, 0, address(this), now + 20);
