如何向js脚本添加自定义标头？

Question

是否可以在以下脚本中添加自定义标头？可以在python中使用，而我只需要在lambda中进行测试即可。

const http = require('http');
exports.handler = async (event, context) => {
    return new Promise((resolve, reject) => {
        const options = {
            host: 'www.some.url.com',
            path: '/api/',
            port: 80,
            method: 'GET'
        };
        const req = http.request(options, (res) => {
          let data = '';

          // A chunk of data has been recieved.
          res.on('data', (chunk) => {
            data += chunk;
          });

          // The whole response has been received. Print out the result.
          res.on('end', () => {
            console.log(JSON.parse(data));
            });

        });
        req.write('');
        req.end();
    });
};

示例为：

host: 'www.some.url.com',
path: '/api/',
port: 80,
method: 'GET'
header: User-Agent: chrome
header: Content-Type: application/xjson

我不是开发人员，所以也许根本不可能：）
