待批准的 ERC-1155 事件

ERC-1155：

   function approve(address _spender, uint256 _id, uint256 _currentValue, uint256 _value) external;

   /**
       @dev Allow other accounts/contracts to spend tokens on behalf of msg.sender
       Also, to minimize the risk of the approve/transferFrom attack vector
       (see https://docs.google.com/document/d/1YLPtQxZu1UAvO9cZ1O2RPXBbT0mooh4DYKjA_jp-RLM/), this function will throw if the current approved allowance does not equal the expected _currentValue, unless _value is 0
       @param _spender        Address to approve
       @param _ids            IDs of the CryptoItems
       @param _currentValues  Expected current values of allowances per item type
       @param _values         Allowance amounts per item type
   */
   function batchApprove(address _spender, uint256[] calldata _ids, uint256[] calldata _currentValues, uint256[] calldata _values) external;

這兩個函式應該發出哪些事件（以及使用哪些參數）？

這兩個函式不屬於 EIP-1155 ( https://eips.ethereum.org/EIPS/eip-1155 )。實際上，EIP 只定義了：

   /**
   @notice Enable or disable approval for a third party ("operator") to manage all of the caller's tokens.
   @dev MUST emit the ApprovalForAll event on success.
   @param _operator  Address to add to the set of authorized operators
   @param _approved  True if the operator is approved, false to revoke approval
*/
function setApprovalForAll(address _operator, bool _approved) external;

但是，approve您提到的方法已在此處實現為 ERC1155 契約的擴展，以允許特定 ID。
