safeTransferFrom 不会将以太币传输到目标 ERC-721

如何解决safeTransferFrom 不会将以太币传输到目标 ERC-721

我与 ERC-721 签订了合同，并尝试用钱转移代币。我正在使用 web3.js 和 openzeppelin。因此，交易被确认，但没有资金发送到目标钱包。

这里是合约买入函数；

function buy(uint256 _tokenId) public payable {
address buyer = msg.sender;

require(_isApprovedOrOwner(msg.sender,_tokenId),"ERC721: transfer caller is not owner nor approved");
approve(buyer,_tokenId);
safeTransferFrom(ownerOf(_tokenId),buyer,_tokenId); 
}

这里是 web3.js :

const buy = (2,2) => {
//Token ID: 2
//Price: 2 ether
contract.methods.buy(2).send({ from: account,value: web3.utils.toWei(2,'ether') })
}

这里是Buy Function的交易响应

请帮帮我。谢谢。

解决方法

我像这样改变了我的合约购买功能；

function buy(uint256 _tokenId,address payable _owner,uint256 _amount) public payable {
    address payable buyer = msg.sender; 
    address payable owner = _owner;  //<-- *payable (important)
    
    _transfer(ownerOf(_tokenId),buyer,_tokenId);
      
    owner.transfer(_amount); //<--- this function send the amount to the token owner.

}

问题解决了！
注意：这是一个简单的合同。如果你想使用，请小心。
