篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了UniswapV2路由合约的函数选择器和事件选择器相关的知识，希望对你有一定的参考价值。
UniswapV2路由合约UniswapV2Router02，其继承于IUniswapV2Router02, 而IUniswapV2Router02又继承于IUniswapV2Router01。路由合约用于在原Token与目标Token之间找到一条兑换路径，比如 TokenA --> TokenB --> TokenC，把TokenA兑换TokenC，需要通过TokenB来继续转接。实际是2个交易对: (TokenA,TokenB)，(Token B,TokenC) 。
路由合约的继承图表如下：
