POST using multipart/form-data in NodeJS - node.js

Question

I need to essentially POST a local image to Cisco Webex room from my NodeJS service. For local files, you need to do a multipart/form-data request instead of JSON as mentioned in the documentation.
The CURL looks like
curl --request POST \
--header "Authorization: Bearer ACCESS_TOKEN" \
--form "files=#/home/desktop/example.png;type=image/png" \
--form "roomId=Y2lzY2....." \
--form "text=example attached" \
https://api.ciscospark.com/v1/messages
But I am not sure how to convert it to nodeJS request format. I tried to use CURL to Node request converter here but doesn't seem like it is handling the multipart/form-data type. Please suggest.
EDIT: after doing some research, I came up with the below code
var request = require('request');
var fs = require('fs');
var params = { roomId: ROOMID,
text: "hello....",
files: {
value: fs.createReadStream(PATH_WO_FILENAME),
options: {
filename: 'image.jpg',
contentType: 'jpg'
}
}
};
var headersWebex = {
'Authorization': 'Bearer MY_BOT_ACCESS_TOKEN',
'Content-Type': 'multipart/form-data' }
request.post({
headers: headersWebex,
url: 'https://api.ciscospark.com/v1/messages',
method: 'POST',
body: params
}, function(error, response, body){
console.log(body);
});
But it is throwing error
undefined
_http_outgoing.js:642
throw new TypeError('First argument must be a string or Buffer');

Answer 1

Ok so here is how I made it work. I essentially needed to look deeper into the docs that #Evan mentioned
var request = require('request');
var fs = require('fs');
var roomID = 'MY_ROOM_ID'
var params = {
roomId: roomID,
text: "hello....",
files: {
value: fs.createReadStream('./image.jpg'),
options: {
filename: 'image.jpg',
contentType: 'image/jpg'
}
}
};
var headersWebex = {
'Authorization': 'Bearer MY_BOT_ACCESS_TOKEN',
'Content-Type': 'application/json'
}
request.post({
headers: headersWebex,
url: 'https://api.ciscospark.com/v1/messages',
method: 'POST',
formData: params
}, function(error, response, body){
if (error)
console.log(error)
console.log(body);
});
