如何使用 Node.js 从 Twilio whatsapp API 下载图像

Question

My goal is to get the image from Twilio api to store it somewhere else because Twilio deletes media after 4h. (See here)

I'm using node and I have read https://www.twilio.com/docs/sms/api/media-resource#fetch-a-media-resource

...and it says that to do a request to this URL without the "json" extension should return the media with its original MIME type

https://api.twilio.com/2010-041/Accounts/{AccountSid}/Messages/{MessageSid}/Media/{Sid}.json

However, i need auth, so I need to use

const client = require('twilio')(accountSid, authToken);

How can I fetch the image? Any sample code to achieve it? In the docs seem to do it without auth.

UPDATE ----------------------------------------

After accessing the MediaUrl0 on the browser, twilio redirects me to the following URL:

https://s3-external-1.amazonaws.com/media.twiliocdn.com/{AccountSid}/{?}

I was thinking of building my own URL but i dont know how to get the {?}

You do not need authentication to retrieve media for an incoming sms . They are all hosted (as of now on Aws S3) and accessible publicly through a (hard to guess) url. you can access them using any http client
