在映射中依賴於參數的查找後找不到成員或不可見成員

pragma solidity >=0.4.0 <0.7.0;

contract New{

   mapping(address => string) public users;

   string name;

   address[] public userAddress ;
   //string[] public userNames;

   function updateUser(string memory name) public{
       users[msg.sender]= name;

   }
   function getUser(address[] calldata) external view returns(string memory){
       return users.name;
   }

}

我想設置一個名字，我想得到我的名字。為此，我做了一個 getUser 函式。但我不知道我的名字。

但我有這樣的錯誤：

browser/asd.sol:17:16: TypeError: Member "name" not found or not visible after argument-dependent lookup in mapping(address => string storage ref). return users.name; ^--------^

我該怎麼辦 ？

試試這個：

pragma solidity >=0.4.0 <0.7.0;

contract New{

   mapping(address => string) public users; // contains a name for every address

   // string name;

   // address[] public userAddress ;
   // string[] public userNames;

   function updateUser(string memory name) public {
       users[msg.sender] = name; // set name for address

   }
   function getUser(address a) public view returns(string memory) {
       return users[a]; // return address name
   }
}

希望能幫助到你。
