如何從 Solidity/Remix 中的映射數組中獲取索引？

我可以將工作人員地址推送到與經理地址的映射。我嘗試像這段程式碼一樣獲取經理地址。

contract Test {

  struct Worker{
       address manager_add;
       address worker_add;
   }

  mapping(address => Worker[]) manager;

  function setWorkerAddress(address worker_add) public{

     manager[msg.sender].push(Worker(msg.sender, worker_add));  // push worker address map with manager address

  }

  function getManagerAddress() public returns(uint){
     return manager[msg.sender].x;  // worker get manage address
  }
}

它顯示這樣的錯誤。

TypeError: Return argument type address is not implicitly convertible to expected type (type of first return variable) uint256.
 --> contracts/test.sol:21:14:
  |
21 |       return manager[msg.sender][index].manager_add;
  |              ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

如何解決？

您正在嘗試查看工人經理的地址。因為您要返回一個地址，所以您必須更改function getManagerAddress(uint index) public returns(uint)為function getManagerAddress(uint index) public returns(address)
