[Twitter] Pulling images from tweets

in Contributed Library Questions • 7 months ago

Hi,

I need help. I'd like to pull images from tweets with a certein hashtag.

I use this API for the first time ever (most of the code is from the tutorial http://blog.blprnt.com/blog/blprnt/updated-quick-tutorial-processing-twitter - that's why I'm using a dated library).

I've managed to pull URLs from tweets but:

1. Not every URL is an image

2. 99% of images are not direct file link but something like this: http://instagram.com/p/XA5EPtQgs6/

I know that it's possible to pull media data only - https://dev.twitter.com/docs/tweet-entities - but it's JSON and I'm kinda lost.

ATM all I get is an error "The file http://instagr.am/p/XA5EPtQgs6/ contains bad image data, or may not be an image."

Here's the code (it's a mess but I was trying to get it to work, not to make it pretty:)

/*
Moje dane:
consumer key:
consumer secret:
acces token:
acces token secret:
*/
//Build an ArrayList to hold all of the words that we get from the imported tweets
ArrayList<String> words = new ArrayList();
String url,y;
URL x;
PImage webImg;
void setup() {
//Set the size of the stage, and the background to black.
size(400,400);
background(0);
smooth();
//Credentials
ConfigurationBuilder cb = new ConfigurationBuilder();
cb.setOAuthConsumerKey("");
cb.setOAuthConsumerSecret("");
cb.setOAuthAccessToken("");
cb.setOAuthAccessTokenSecret("");
//Make the twitter object and prepare the query
Twitter twitter = new TwitterFactory(cb.build()).getInstance();
Query query = new Query(""#art"");
query.setRpp(100);
//Try making the query request.
try {
QueryResult result = twitter.search(query);
ArrayList tweets = (ArrayList) result.getTweets();
for (int i = 0; i < tweets.size(); i++) {
Tweet t = (Tweet) tweets.get(i);
String user = t.getFromUser();
String msg = t.getText();
//url = t.getProfileImageUrl();
//url = t.getURL();
//URL url = t.getURL();
Date d = t.getCreatedAt();
//println("Tweet by " + user + " at " + d + ": " + msg);
URLEntity[] urls = t.getURLEntities();
for(URLEntity url : urls){
//System.out.println("A TO JEST DZIWNE" + url.getURL());
x = url.getExpandedURL();
println(url.getURL());
}
//Break the tweet into words
String[] input = msg.split(" ");
for (int j = 0; j < input.length; j++) {
//Put each word into the words ArrayList
words.add(input[j]);
}
};
}
catch (TwitterException te) {
println("Couldn't connect: " + te);
};
}
void draw() {
//Draw a faint black rectangle over what is currently on the stage so it fades over time.
fill(0,1);
//rect(0,0,width,height);
//Draw a word from the list of words that we've built
int i = (frameCount % words.size());
String word = words.get(i);
//Put it somewhere random on the stage, with a random size and colour
fill(255,random(50,150));
textSize(random(10,30));
text(word, random(width), random(height));
//String img = url;
// Load image from a web server
if(mousePressed){
word= words.get(i+1);
}
y=""+x;
//println(y);
webImg = loadImage(y, "jpg");
image(webImg,0,0);
}

Thx! :)
