Delphi代码：

uses
      IdGlobal, IdHashSHA, IdHMACSHA1, IdSSLOpenSSL
    
    //Add by wh 2021-03-19
    function HMACSHA256(const sValue, sKey: String): String;
    var
      hmac: TIdHMACSHA256;
      hash: TIdBytes;
    begin
      LoadOpenSSLLibrary;
      if not TIdHashSHA256.IsAvailable then
        raise Exception.Create('SHA256 hashing is not available!');
      hmac := TIdHMACSHA256.Create;
      try

        Result := LowerCase(ToHex(hash));
      finally
        hmac.Free;
