universal_router 中inputs bytes要如何构造 web3j

if (command == Commands.V2_SWAP_EXACT_IN) { // equivalent: abi.decode(inputs, (address, uint256, uint256, bytes, bool)) address recipient; uint256 amountIn; uint256 amountOutMin; bool payerIsUser; assembly { recipient := calldataload(inputs.offset) amountIn := calldataload(add(inputs.offset, 0x20)) amountOutMin := calldataload(add(inputs.offset, 0x40)) // 0x60 offset is the path, decoded below payerIsUser := calldataload(add(inputs.offset, 0x80)) } address[] calldata path = inputs.toAddressArray(3); address payer = payerIsUser ? lockedBy : address(this); v2SwapExactInput(map(recipient), amountIn, amountOutMin, path, payer); }
