let provider = new ethers.providers.JsonRpcProvider("..."); let wallet = initMnemonicWallet(provider); let contractIns = new ethers.Contract(routerAddr, Abi, provider);

let contractSinger = contractIns.connect(wallet);

contractSinger.swap();

老师上面是您上回的回复，可是调用时需要设置"gasPrice":{},"nonce":{},"gasLimit":{},"chainId":{}等参数 是同步调用函数时进行设置还是调用前统一进行设置，设置这个的相关代码麻烦给一下，老师辛苦了
