First, use POST multipart/form-data or base64 encoded files to .1/media/upload.json.

but get error : code 38 "media parameter is missing."

here is my code

var Twitter = require('./twitter.js');
var request = require('request');
var fs = require('fs');
var path = require('path');
var FormData = require('form-data');
var utf8 = require('utf8');
var base64_encode = require('base64').encode;

var oauth = {
    consumer_key: '',
    consumer_secret: '',
    token: '',
    token_secret: ''
};

var form = new FormData();
fs.readFile(__dirname + '/image.jpg', function(err, data) {
    if (err) {
        throw err;
    }
    var encoded = base64_encode(data);
    form.append('media[]', encoded); // I've also tried media instead of media[]
    form.getLength(function(err, length) {
        var r = request.post({
            url: '.1/media/upload.json',
            oauth: oauth,
        }, function(error, response, body) {
            if (error) {
                console.error(error);
                return;
            }
            console.dir(body);
        });
        r._form = form;
        r.setHeader('content-length', length);
    });
});

I reuse code from this topic : Upload images to twitter API from node.js

Any suggestion? Thank you

• javascript
• node.js

• Did you try just media and not media[]? – mscdex Commented Oct 13, 2014 at 13:17
• Yes, I did. Same result. – Methuz Kaewsai-kao Commented Oct 13, 2014 at 13:43

Here is what I use to upload media :
(I only use OAuth to create Oauth authentification)
I also add /statuses/update.json to link a new post to your media.

var oauth = require('oauth');
var fs = require('fs');

var a = new oauth.OAuth("https://twitter./oauth/request_token",
    "https://twitter./oauth/access_token",
    config.consumerKey,
    config.consumerSecret,
    "1.0",
    config.callbackUrl,
    "HMAC-SHA1");

a.post("https://upload.twitter./1.1/media/upload.json", oauth_access_token, oauth_access_token_secret, {media:fs.readFileSync(file_path).toString("base64")} ,"" , function (e, data, res){
    if (e) {
        console.error(e);
    }else {
        try{
            data = JSON.parse(data);
        }catch (e){
            console.error("Error Json : " + e);
        }
        console.log(data.media_id);

        a.post("https://api.twitter./1.1/statuses/update.json", oauth_access_token, oauth_access_token_secret, {status:message,media_ids:[data.media_id_string]}, "", function (e, data, res){
            if (e) {
                console.error(e);
            }else {
                console.log("Success");
            }
        });
    }
});

PHP solution

Libraries taken from here: https://github./abraham/twitteroauth Check your image limit here: https://dev.twitter./rest/reference/get/help/configuration

The glitch is to send base64_encode data and the size to not exceed the image limitation (default is 3MB) otherwise you will receive "not recognized." error.

Here is the code (only the image upload thing) which worked for me: require_once('includes/twitter/twitteroauth.php');

$connection = new TwitterOAuth(CONSUMER_KEY, CONSUMER_SECRET, ACCESS_TOKEN, ACCESS_SECRET);

$filePath = '/absolute path to the file/';
$url = 'https://upload.twitter./1.1/media/upload.json';
$method = 'POST';
$parameters = array(
    'media' => base64_encode(file_get_contents($filePath)),
);
$request = OAuthRequest::from_consumer_and_token($connection->consumer, $connection->token, $method, $url, $parameters);
$request->sign_request($connection->sha1_method, $connection->consumer, $connection->token);

$response = $connection->http($request->get_normalized_http_url(), $method, $request->to_postdata());
if ($connection->format === 'json' && $connection->decode_json) {
    $response = json_decode($response);
}
print_r($response);
