Remix没有显示对契约部署的构造函数调用(remix中的bug？)

Question

我想测试与我的客户端一起发送ERC20令牌，所以我需要在一个测试网上创建一些令牌。我正在使用Remix和，但是混合已经不再是我习惯的了。当我在此之前(创建一个契约)时，曾经有一个文本字段，可以在其中放置构造函数参数来部署契约。但是现在我看到的只是Local contract from Address的一个测试字段。以前存在的构造函数字段在哪里？

我看到的是：

这是我的合同：

/*
Implements EIP20 token standard: https://github.com/ethereum/EIPs/blob/master/EIPS/eip-20.md
.*/


pragma solidity ^0.4.21;

import "./EIP20Interface.sol";
import "./SafeMath.sol";


contract MyToken is EIP20Interface {

    uint256 constant private MAX_UINT256 = 2**256 - 1;
    mapping (address => uint256) public balances;
    mapping (address => mapping (address => uint256)) public allowed;
    /*
    NOTE:
    The following variables are OPTIONAL vanities. One does not have to include them.
    They allow one to customise the token contract & in no way influences the core functionality.
    Some wallets/interfaces might not even bother to look at this information.

    string public name;                   //fancy name: eg Simon Bucks
    uint8 public decimals;                //How many decimals to show.
    string public symbol;                 //An identifier: eg SBX

    function Constructor (
        uint256 _initialAmount,
        string _tokenName,
        uint8 _decimalUnits,
        string _tokenSymbol
    ) public {
        balances[msg.sender] = _initialAmount;               // Give the creator all initial tokens
        totalSupply = _initialAmount;                        // Update total supply
        name = _tokenName;                                   // Set the name for display purposes
        decimals = _decimalUnits;                            // Amount of decimals for display purposes
        symbol = _tokenSymbol;                               // Set the symbol for display purposes
    }

    function transfer(address _to, uint256 _value) public returns (bool success) {
        require(balances[msg.sender] >= _value);
        balances[msg.sender] = SafeMath.sub(balances[msg.sender], _value);
        balances[_to] = SafeMath.add(balances[_to], _value);
        emit Transfer(msg.sender, _to, _value); //solhint-disable-line indent, no-unused-vars
        return true;
    }

    function transferFrom(address _from, address _to, uint256 _value) public returns (bool success) {
        uint256 allowance = allowed[_from][msg.sender];
        require(balances[_from] >= _value && allowance >= _value);
        balances[_to] = SafeMath.add(balances[_to], _value);
        balances[_from] = SafeMath.sub(balances[_from], _value);
        if (allowance < MAX_UINT256) {
            allowed[_from][msg.sender] = SafeMath.sub(allowed[_from][msg.sender], _value);
        }
        emit Transfer(_from, _to, _value); //solhint-disable-line indent, no-unused-vars
        return true;
    }

    function balanceOf(address _owner) public view returns (uint256 balance) {
        return balances[_owner];
    }

    function approve(address _spender, uint256 _value) public returns (bool success) {
        allowed[msg.sender][_spender] = _value;
        emit Approval(msg.sender, _spender, _value); //solhint-disable-line indent, no-unused-vars
        return true;
    }

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

编辑：

我发现，如果我将构造函数从Constructor更改为MyToken，它就能工作。显然，remix重新推荐使用Constructor并使用类名作为废弃的调用，但是如果这样做，您将无法部署您的合同。听起来像虫子？

Answer 1

您不必在构造函数前面添加函数关键字。它不会在部署期间出现，因为您将它声明为契约函数。删除函数关键字并尝试。肯定会成功的。

constructor (uint256 _initialAmount, string _tokenName, uint8 _decimalUnits, string _tokenSymbol) public {
    balances[msg.sender] = _initialAmount; // Give the creator all initial tokens 
    totalSupply = _initialAmount; // Update total supply 
    name = _tokenName; // Set the name for display purposes 
    decimals = _decimalUnits; // Amount of decimals for display purposes 
    symbol = _tokenSymbol; // Set the symbol for display purposes 
}

转到右上角的“编译”选项卡，单击“编译”按钮，然后勾选“自动编译”复选框。

当您返回部署时，应该有文本框来传递初始参数。
