如何从firebase云函数发送自定义响应？

const functions = require('firebase-functions');

exports.customResponse = functions.https.onRequest((request, response) => {
  // 在这里编写自定义响应的逻辑
});

response.status(200).send('自定义响应');

const data = {
  message: '自定义响应',
  status: 'success'
};

response.status(200).json(data);

const queryParam = request.query.param;

if (queryParam === 'value1') {
  response.status(200).send('自定义响应1');
} else if (queryParam === 'value2') {
  response.status(200).send('自定义响应2');
} else {
  response.status(400).send('无效的参数');
}
