Ethereum ERC20 토큰 계약은 리믹스 배포 계약 주소로 월렛에 추가 할 때 토큰 잔액을 반환합니다

Question

아래와 같이 리믹스 편집기에서 ERC20 토큰 스마트 계약 생성을 시도했습니다.

스마트 계약을 배포 할 수 있고 모든 변수가 유지되지만 계약서를 wallet.ethereum.org 계약 페이지 (감시 토큰 아래)에 추가하면 토큰 잔액이 으로 표시되고 토큰 심볼 , 이름, 소수 자릿수가 모두 올바르게 등록됩니다.

코드 : 계약을 배포 할 때 당신은 균형을 설정하지 않을

pragma solidity ^0.4.19; 
//import './IERC20.sol'; 

//contract FuncToken is IERC20 { 

interface IERC20 { 
    function totalsupply() constant returns(uint256 total); 
    function balanceof(address _owner)constant returns(uint256 balance); 
    function transfer(address to, uint256 value)returns(bool success); 
    function transferfrom(address from,address to,uint256 _value) returns(bool success); 
    function approve(address spender,uint256 value)returns(bool success); 
    function allowance(address owner,address spender)constant returns(uint256 remaining); 

    event Transfer(address indexed from,address indexed to,uint256 _value); 
    event Approval(address indexed owner,address indexed spender,uint256 _value); 
} 

contract PerlToken{ 
    uint public constant _totalSupply=100000; 
    string public constant symbol="perl"; 
    string public constant name="PERL Token"; 
    uint8 public constant decimals=3; 

    mapping(address=>uint256) balances; 
    mapping(address=>mapping(address =>uint256)) allowed; 

    function FuncToken(){ 
     balances[msg.sender]=_totalSupply; 
    } 
    function totalsupply() constant returns(uint256 total){ 

     return _totalSupply; 
    } 
    function balanceof(address _owner)constant returns(uint256 balance){ 
     return balances[_owner]; 
    } 
    function transfer(address to, uint256 value)returns(bool success){ 
     require(
      balances[msg.sender]>=_value && _value>0 
      ); 
     balances[msg.sender] -=_value; 
     balances[_to] +=+_value; 
     Transfer(msg.sender,_to,_value); 
     return true; 

    } 
    function transferfrom(address from,address to,uint256 _value) returns(bool success){ 
     require(
      allowed[_from][msg.sender]>=_value 
      && balances[_from]>=_value 
      && _value>0 
      ); 

      balances[_from]-=_value; 
      balances[_to]+= _value; 
      allowed[_from][msg.sender]-=_value; 
      Transfer(_from,_to,_value); 
      return true; 
    } 
    function approve(address spender,uint256 value)returns(bool success){ 
     allowed[msg.sender][_spender]=_value; 
     Approval(msg.sender,_spender,_value); 
     return true; 

    } 
    function allowance(address owner,address spender)constant returns(uint256 remaining){ 
     allowed[_owner][_spender]; 

    } 

    event Transfer(address indexed from,address indexed to,uint256 _value); 
    event Approval(address indexed owner,address indexed spender,uint256 _value);

. 나는 당신이 생성자로 FuncToken을 사용하고자한다고 믿습니다.

계약서를 정리하고 (여기서는 0.4.17을 사용하고 있습니다.) 배포하고 Mist로 가져 왔습니다. 이제 좋아 보인다.

pragma solidity ^0.4.17; 
//import './IERC20.sol'; 

//contract FuncToken is IERC20 { 

interface IERC20 { 
    function totalSupply() constant returns(uint256 total); 
    function balanceOf(address _owner)constant returns(uint256 balance); 
    function transfer(address to, uint256 value)returns(bool success); 
    function transferFrom(address from,address to,uint256 _value) returns(bool success); 
    function approve(address spender,uint256 value)returns(bool success); 
    function allowance(address owner,address spender)constant returns(uint256 remaining); 

    event Transfer(address indexed from,address indexed to,uint256 _value); 
    event Approval(address indexed owner,address indexed spender,uint256 _value); 
} 

contract PerlToken{ 
    uint public constant _totalSupply=100000; 
    string public constant symbol="perl"; 
    string public constant name="PERL Token"; 
    uint8 public constant decimals=3; 

    mapping(address=>uint256) balances; 
    mapping(address=>mapping(address =>uint256)) allowed; 

    function PerlToken(){ 
     balances[msg.sender]=_totalSupply; 
    } 
    function totalSupply() constant returns(uint256 total){ 

     return _totalSupply; 
    } 
    function balanceOf(address _owner)constant returns(uint256 balance){ 
     return balances[_owner]; 
    } 
    function transfer(address _to, uint256 _value)returns(bool success){ 
     require(
      balances[msg.sender]>=_value && _value>0 
      ); 
     balances[msg.sender] -=_value; 
     balances[_to] +=+_value; 
     Transfer(msg.sender,_to,_value); 
     return true; 

    } 
    function transferFrom(address _from,address _to,uint256 _value) returns(bool success){ 
     require(
      allowed[_from][msg.sender]>=_value 
      && balances[_from]>=_value 
      && _value>0 
      ); 

      balances[_from]-=_value; 
      balances[_to]+= _value; 
      allowed[_from][msg.sender]-=_value; 
      Transfer(_from,_to,_value); 
      return true; 
    } 
    function approve(address _spender,uint256 _value)returns(bool success){ 
     allowed[msg.sender][_spender]=_value; 
     Approval(msg.sender,_spender,_value); 
     return true; 

    } 
    function allowance(address _owner,address _spender)constant returns(uint256 remaining){ 
     allowed[_owner][_spender]; 

    } 

    event Transfer(address indexed from,address indexed to,uint256 _value); 
    event Approval(address indexed owner,address indexed spender,uint256 _value); 
}
