[Twitter] Pulling images from tweets

[0 Replies]

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:)
2. /*
3. Moje dane:
4. consumer key:
5. consumer secret:
7. acces token:
8. acces token secret:
9. */
11. //Build an ArrayList to hold all of the words that we get from the imported tweets
12. ArrayList<String> words = new ArrayList();
13. String url,y;
14. URL x;
15. PImage webImg;
16. void setup() {
17. //Set the size of the stage, and the background to black.
18. size(400,400);
19. background(0);
20. smooth();
22. //Credentials
23. ConfigurationBuilder cb = new ConfigurationBuilder();
24. cb.setOAuthConsumerKey("");
25. cb.setOAuthConsumerSecret("");
26. cb.setOAuthAccessToken("");
27. cb.setOAuthAccessTokenSecret("");
29. //Make the twitter object and prepare the query
30. Twitter twitter = new TwitterFactory(cb.build()).getInstance();
31. Query query = new Query(""#art"");
32. query.setRpp(100);
33. //Try making the query request.
35. try {
36. QueryResult result = twitter.search(query);
37. ArrayList tweets = (ArrayList) result.getTweets();
39. for (int i = 0; i < tweets.size(); i++) {
40. Tweet t = (Tweet) tweets.get(i);
41. String user = t.getFromUser();
42. String msg = t.getText();
43. //url = t.getProfileImageUrl();
44. //url = t.getURL();
45. //URL url = t.getURL();
46. Date d = t.getCreatedAt();
47. //println("Tweet by " + user + " at " + d + ": " + msg);
49. URLEntity[] urls = t.getURLEntities();
50. for(URLEntity url : urls){
51. //System.out.println("A TO JEST DZIWNE" + url.getURL());
52. x = url.getExpandedURL();
53. println(url.getURL());
54. }
55. //Break the tweet into words
56. String[] input = msg.split(" ");
57. for (int j = 0; j < input.length; j++) {
58. //Put each word into the words ArrayList
59. words.add(input[j]);
60. }
61. };
63. }
67. catch (TwitterException te) {
68. println("Couldn't connect: " + te);
69. };
70. }
72. void draw() {
73. //Draw a faint black rectangle over what is currently on the stage so it fades over time.
74. fill(0,1);
75. //rect(0,0,width,height);
77. //Draw a word from the list of words that we've built
78. int i = (frameCount % words.size());
79. String word = words.get(i);
81. //Put it somewhere random on the stage, with a random size and colour
82. fill(255,random(50,150));
83. textSize(random(10,30));
84. text(word, random(width), random(height));
85. //String img = url;
86. // Load image from a web server
87. if(mousePressed){
88. word= words.get(i+1);
89. }
90. y=""+x;
91. //println(y);
92. webImg = loadImage(y, "jpg");
93. image(webImg,0,0);
94. }
Thx! :)
