不知道行不行，试试吧

exports.main = async (event, context) => {
  var option = {
    headers: {
      'Accept': '*/*',
      'Accept-Encoding': 'utf-8',
      'Accept-Language': 'zh-CN,zh;q=0.8',
      'Connection': 'keep-alive',
      'user-agent': 'Mozilla/5.0 (Linux; Android 5.0; SM-G900P Build/LRX21T) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/78.0.3904.97 Mobile Safari/537.36',
    }
  };
  return await new Promise((resolve, reject) => {
    try {
		https.get(event.url, option, (res) => {
			var contont = '', location = res.headers.location
			res.on('data', (chunk) => {
				contont += chunk
			});
			res.on('end', () => {
				resolve({location,contont})
			});
		}).on('error', (e) => {
			reject(e)
		});
    } catch (e) {
      reject(e)
    }
  })
}
