Blockchain 使用web3从智能合约中提取乙醚到特定帐户

我在智能合约中有如下功能：

function transferToaddress(address payable addressToSend) public payable{
    addressToSend.transfer(0.5 ether);
}

var response = await this.contract.transferToaddress(vm.userAccountAddress,{
   from: vm.userAccountAddress,
   gas: vm.gas
})

从我的前端，我按如下方式调用上述函数：

function transferToaddress(address payable addressToSend) public payable{
    addressToSend.transfer(0.5 ether);
}

var response = await this.contract.transferToaddress(vm.userAccountAddress,{
   from: vm.userAccountAddress,
   gas: vm.gas
})

交易失败。我的合同有一些平衡。点击一个按钮，我希望一些乙醚（本例中为0.5）从智能合约传输到传递给函数的地址。 知道我做错了什么吗

var response = await this.contract.transferToaddress(vm.userAccountAddress)
.send({ from: vm.userAccountAddress, gas: vm.gas })

您错过了send关键字

合同不应支付，因为用户正在获取以太，而它没有提供以太

function transferToaddress(address payable addressToSend) public{
    addressToSend.transfer(0.5 ether);
}

var response = await this.contract.transferToaddress(vm.userAccountAddress)
    .send({ from: vm.userAccountAddress, gas: vm.gas })
