Guide to sending a binary body in a POST request using Meteor.js

I've been struggling with a challenging issue in Meteor.js that I'm hoping to resolve. My goal is to make API calls to a face detection open API service by sending an image and receiving a JSON object in return. However, I have hit a roadblock as I can't figure out how to send an image in the post body using Meteor.js. The default http package in Meteor offers the following methods:

HTTP.post(url, [callOptions], [asyncCallback])

or

HTTP.call(method, url, [options], [asyncCallback])

with the options

[options]  
 data Object
    A JSON-able object to stringify and use as the HTTP request body. Overwrites content.

My main question revolves around how to include a binary stream in the post body.

If anyone could provide assistance, it would be greatly appreciated.

Answer №1

It seems like accomplishing this task with Meteor HTTP.call may not be possible.

Upon examining their source code located at https://github.com/meteor/meteor/blob/devel/packages/http/httpcall_client.js, you will come across the following snippet:

content = JSON.stringify(options.data);

If you need to transmit binary data, it is advised to utilize XMLHttpRequest and FileReader API.

I previously provided insight on a similar subject in response to another question posted on Stack Overflow: Meteor: uploading file from client to Mongo collection vs file system vs GridFS (using Option 2)
