利用WP_Query 类，即tax_query 和fields 参数。从$found_posts 所有物请注意，这是示例代码。

$query = new WP_Query( [
  \'post_type\' => \'games\',
  \'tax_query\' = [
    \'relation\' => \'AND\',
    [
      \'taxonomy\' => \'game_status\',
      \'field\' => \'slug\',
      \'terms\' => [ \'beaten\' ],
    ],
    [
      \'taxonomy\' => \'console\',
      \'field\' => \'slug\',
      \'terms\' => [ \'switch\' ],
    ]
  ],
  \'fields\' => \'ids\',
] );

$count = $query->found_posts;
