js读取文件内容 ，每行一条。

function readFile(filePath) {
  try {
      const data = fs.readFileSync(filePath, 'utf-8');
      return data.split('\n').map(line => line.trim()).filter(line => line !== '');
  } catch (error) {
      logger(`Error reading ${filePath}:`, 'error', error.message || error);
      return [];
  }
}
