未擷取的類型錯誤：contract.name 不是函式

我正在嘗試檢查我是否正確部署了帶有鬆露和甘納許的契約。我跑truffle console，然後contract = await Kryptobird.deployed()。但是當我嘗試獲取契約的名稱時，我遇到了這個錯誤

truffle(development)> contract.name()
evalmachine.<anonymous>:0
contract.name()
        ^

Uncaught TypeError: contract.name is not a function
   at evalmachine.<anonymous>

合約程式碼

// SPDX-License-Identifier: MIT
pragma solidity ^0.8.0;


contract Kryptobird{

   string private name;
   string private symbol;

   constructor() {

       name = 'Kryptobirdz';
       symbol = 'KBIRDZ';
   }
}    

string private name;

它被明確設置為私有可見性，這意味著它不可見……意味著沒有name()功能。

如果能見度是，將生成一個大致如下的函式public：

function name() public view returns(string memory) {
 return name;
}

但它不是，所以沒有功能。

希望能幫助到你。

解決方案程式碼是

// SPDX-License-Identifier: MIT
pragma solidity ^0.8.0;


contract Kryptobird{

   string private _name;
   string private _symbol;

   constructor() {

       _name = 'Kryptobirdz';
       _symbol = 'KBIRDZ';
   }

   function name() public view returns(string memory) {
       return _name;
   }

   function symbol() public view returns(string memory) {
       return _symbol;
   }

}
