问题
I am building a sample smart contract . I am trying to deposit ether from 1 account to another but the issue is amount is deducted from the sender's account but not able to deposit to receiver's account.
Here is my contract code :
pragma solidity ^0.5.0;
contract ApprovalContract{
address public sender;
address public receiver;
function deposit(address _receiver) external payable {
require(msg.value > 0);
sender = msg.sender;
receiver = _receiver;
address payable _rec = receiver.make_payable();
_rec.transfer(address(this).balance);
}
using address_make_payable for address;
}
library address_make_payable {
function make_payable(address x) internal pure returns (address payable) {
return address(uint160(x));
}
}
Here is my web3 code :
let ApprovalContract = new web3.eth.Contract(
abi,
"0xABd4495e3afc9E61Bbbf54620587aB4B48CEd7d3" //contract address
);
ApprovalContract.methods
.deposit("0xF33ca58CbD25bC0fFe5546Dc494E5c61C8D7fFc3")
.send(
{
from: "0x7186ffcf5ea764257fdbaefccb9472f054495d11",
gas: 100000,
value: web3.utils.toWei("1", "ether")
},
(err, res) =>
err
? console.log(`error: ${err}`)
: console.log(`Success: ${res}`)
);
回答1:
Just add some mapping in your smart contract, like this mapping( address => uint256 ) balance
and this is fixed smart contract for you :
pragma solidity ^0.5.0;
contract ApprovalContract{
address payable owner = msg.sender;
mapping(address => uint256) balance;
function deposit() external payable {
require(msg.value > 0);
sender = msg.sender;
deposited = msg.value;
receiver = owner;
balance[sender] = deposited;
receiver.transfer(deposited);
}
}
