fb-upload-image.js

/*
Would be updated

"use strict"

const request = require("request");
const fs = require("fs");
const image = fs.createReadStream("path/to/image.jpg ")

//run from terminal /node app.js/ and get variables from command line
const args = process.argv.slice(2);
const token = args[0];
const fbEnd = "https://graph.facebook.com";
const endpoint = fbEnd + "/v2.6/me/messages?access_token=" + token;

//make 'POST' request and create form (multipart/form-data)
const r = request.post(endpoint, (err, httpResponse, body) => {
    if (err) {return console.error("upload failed: ", err)};
    console.log("upload successfull. server respond: ", body) //FB always sends 'OK' status,
                                                              //so to check errors, look at body.error (if any)
});
const form = r.form();

form.append('recipient', JSON.stringify({id: "1351158114933843"}));
form.append('text', 'look at image'); //sadly, but fb never shows text while uploading/sending image; bug?!
form.append('message', JSON.stringify({attachment:{type:"image", payload:{is_reusable:true}}}));
form.append('filedata', image);
