smartcontracts - 我正在尝试在想要用以太预订我的艺术家但我收到 ParserError 的俱乐部发起人之间建立一个托管智能联系

Question

我编译时遇到的错误是：(ParserError: Expected primary expression.price = _price; * (1 ether);)

我想为发起人添加一个 7 天的时间戳，以将所有资金全部添加到托管中，而不是一半以满足我预订我们的条件。这甚至可能作为我们加入的条件吗？我是否需要在我的智能合约中添加多重签名以使其在双方都安全，或者这段代码可以吗？谁能帮我解决这个问题？

    function deposit() onlyBuyer public payable {
        require(currState == State.AWAITING_PAYMENT, "Already paiid");
        require(msg.value == price, "Wrong deposit amount");
        currState = State.AWAITING_DELIVERY;
    
    }
    
    function confimDelivery() onlyBuyer payable public {
        require(currState == State.AWAITING_DELIVERY, "Cannot confirm delivery");
        seller.transfer(price);
        currState = State.COMPLETE;
    }

    function withdraw() onlyBuyer payable public {
        require(currState == State.AWAITING_DELIVERY, "Cannot withdraw at this stage");
        payable(msg.sender).transfer(price);
        currState = State.COMPLETE;
    }

}

Answer 1

您price在constructor.

代替

// original code, extra semicolon
price = _price; * (1 ether);

和

// updated code, removed the semicolon
price = _price * (1 ether);
