安全读取查询字符串参数的最佳方法？

const cloud = require('tencentcloud-sdk-nodejs');
const scf = new cloud.scf.v20180416.Client({
  credential: {
    secretId: 'your_secret_id',
    secretKey: 'your_secret_key',
  },
  region: 'ap-guangzhou',
  profile: {
    httpProfile: {
      endpoint: 'scf.tencentcloudapi.com',
    },
  },
});

exports.main_handler = async (event, context, callback) => {
  const query = event.queryStringParameters;
  // 在这里处理查询字符串参数
  return {
    isBase64Encoded: false,
    statusCode: 200,
    headers: { 'Content-Type': 'application/json' },
    body: JSON.stringify({ message: 'success' }),
  };
};
