etherjs调用合约过程

前言：调用合约成功，虽然是一小步，但总算有进展了，慢慢往前。

 

 方式一，直接使用私钥，读写合约

// library是provider

const { account, library, active } = useWeb3React();


// 取消挂单
  async function cancelOrder(orderHash: string) {
    var privateKey = "";
    let wallet = new ethers.Wallet(privateKey, library);

    var contractAddr = "0xf1730217Bd65f86D2F008f1821D8Ca9A26d64619";
    var jsonStr = '[{"inputs":[{"internalType":"address","name":"perpetualV1","type":"address"},{"internalType":"uint256","name":"chainId","type":"uint256"}],"payable":false,"stateMutability":"nonpayable","type":"constructor"},{"anonymous":false,"inputs":[{"indexed":true,"internalType":"address","name":"maker","type":"address"},{"indexed":false,"internalType":"bytes32","name":"orderHash","type":"bytes32"}],"name":"LogOrderApproved","type":"event"},{"anonymous":false,"inputs":[{"indexed":true,"internalType":"address","name":"maker","type":"address"},{"indexed":false,"internalType":"bytes32","name":"orderHash","type":"bytes32"}],"name":"LogOrderCanceled","type":"event"},{"anonymous":false,"inputs":[{"indexed":false,"internalType":"bytes32","name":"orderHash","type":"bytes32"},{"indexed":false,"internalType":"bytes32","name":"flags","type":"bytes32"},{"indexed":false,"internalType":"uint256","name":"triggerPrice","type":"uint256"},{"components":[{"internalType":"uint256","name":"amount","type":"uint256"},{"internalType":"uint256","name":"price","type":"uint256"},{"internalType":"uint256","name":"fee","type":"uint256"},{"internalType":"bool","name":"isNegativeFee","type":"bool"}],"indexed":false,"internalType":"structP1Orders.Fill","name":"fill","type":"tuple"}],"name":"LogOrderFilled","type":"event"},{"constant":true,"inputs":[],"name":"_EIP712_DOMAIN_HASH_","outputs":[{"internalType":"bytes32","name":"","type":"bytes32"}],"payable":false,"stateMutability":"view","type":"function"},{"constant":true,"inputs":[{"internalType":"bytes32","name":"","type":"bytes32"}],"name":"_FILLED_AMOUNT_","outputs":[{"internalType":"uint256","name":"","type":"uint256"}],"payable":false,"stateMutability":"view","type":"function"},{"constant":true,"inputs":[],"name":"_PERPETUAL_V1_","outputs":[{"internalType":"address","name":"","type":"address"}],"payable":false,"stateMutability":"view","type":"function"},{"constant":true,"inputs":[{"internalType":"bytes32","name":"","type":"bytes32"}],"name":"_STATUS_","outputs":[{"internalType":"enumP1Orders.OrderStatus","name":"","type":"uint8"}],"payable":false,"stateMutability":"view","type":"function"},{"constant":false,"inputs":[{"internalType":"address","name":"sender","type":"address"},{"internalType":"address","name":"maker","type":"address"},{"internalType":"address","name":"taker","type":"address"},{"internalType":"uint256","name":"price","type":"uint256"},{"internalType":"bytes","name":"data","type":"bytes"},{"internalType":"bytes32","name":"","type":"bytes32"}],"name":"trade","outputs":[{"components":[{"internalType":"uint256","name":"marginAmount","type":"uint256"},{"internalType":"uint256","name":"positionAmount","type":"uint256"},{"internalType":"bool","name":"isBuy","type":"bool"},{"internalType":"bytes32","name":"traderFlags","type":"bytes32"}],"internalType":"structP1Types.TradeResult","name":"","type":"tuple"}],"payable":false,"stateMutability":"nonpayable","type":"function"},{"constant":false,"inputs":[{"components":[{"internalType":"bytes32","name":"flags","type":"bytes32"},{"internalType":"uint256","name":"amount","type":"uint256"},{"internalType":"uint256","name":"limitPrice","type":"uint256"},{"internalType":"uint256","name":"triggerPrice","type":"uint256"},{"internalType":"uint256","name":"limitFee","type":"uint256"},{"internalType":"address","name":"maker","type":"address"},{"internalType":"address","name":"taker","type":"address"},{"internalType":"uint256","name":"expiration","type":"uint256"}],"internalType":"structP1Orders.Order","name":"order","type":"tuple"}],"name":"approveOrder","outputs":[],"payable":false,"stateMutability":"nonpayable","type":"function"},{"constant":false,"inputs":[{"components":[{"internalType":"bytes32","name":"flags","type":"bytes32"},{"internalType":"uint256","name":"amount","type":"uint256"},{"internalType":"uint256","name":"limitPrice","type":"uint256"},{"internalType":"uint256","name":"triggerPrice","type":"uint256"},{"internalType":"uint256","name":"limitFee","type":"uint256"},{"internalType":"address","name":"maker","type":"address"},{"internalType":"address","name":"taker","type":"address"},{"internalType":"uint256","name":"expiration","type":"uint256"}],"internalType":"structP1Orders.Order","name":"order","type":"tuple"}],"name":"cancelOrder","outputs":[],"payable":false,"stateMutability":"nonpayable","type":"function"},{"constant":true,"inputs":[{"internalType":"bytes32[]","name":"orderHashes","type":"bytes32[]"}],"name":"getOrdersStatus","outputs":[{"components":[{"internalType":"enumP1Orders.OrderStatus","name":"status","type":"uint8"},{"internalType":"uint256","name":"filledAmount","type":"uint256"}],"internalType":"structP1Orders.OrderQueryOutput[]","name":"","type":"tuple[]"}],"payable":false,"stateMutability":"view","type":"function"}]';
    var jsonAbi = JSON.parse(jsonStr);

    // 取到合约
    let contract = new ethers.Contract(contractAddr, jsonAbi, wallet);
    console.log(contract);
    contract.cancelOrder();

　　  console.log(stringOrder);

    var jsonOrder = JSON.parse(stringOrder);

    console.log(jsonOrder);

    // 调用合约方法 Sign and send tx and wait for receipt

    const createReceipt = await contract.cancelOrder(jsonOrder);

    await createReceipt.wait();

    console.log(`Tx successful with hash: ${createReceipt.hash}`);

// await axios.post(
    //   `http://${SERVER_HOST}:${SERVER_PORT}/orderbook/v1/cancelOrder`,
    //   { ordersHash: [orderHash] }
    // );
    // dispatch(removeOrder(orderHash));
  }

 

方式二：没有私钥，使用metamask签名

其中getSigner()是签名

// deposit
    const iface = PerpetualV1__factory.createInterface();
    // check allowance
    const data = iface.encodeFunctionData("deposit", [account, amount]);
    // 授权两个参数：to是永续合约的地址；data是deposit(account, amount)
    await library
      .getSigner()
      .sendTransaction({ to: PERPETUAL_PROXY_ADDR, data });
