擴展合約時如何呼叫外部建構子並傳遞參數？

我有以下契約

import "zeppelin-solidity/contracts/token/ERC721/ERC721Token.sol";

contract Contract is ERC721Token {
   function Contract(string _name, string _symbol) public { 
       name_ = _name; // This does not work because name_ is internal
       symbol_ = _symbol; // This does not work because symbol_ is internal
   }
}

ERC721Token 合約在**建構子中設置了一個****name_**變數，如何呼叫這個建構子或從這個合約設置 var？

您可以呼叫超級建構子作為聲明的一部分：

constructor(string _name, string _symbol) ERC721Token(_name, _symbol) public {    
    // Any additional constructor code you need
}
