Processing and Twitter (Read 65234 times)

PhiLho YaBB Moderator Offline Posts: 4190 Near Paris (France)	Re: Processing and Twitter Reply #45 - May 1^st, 2009, 2:27am I think it is not a problem of scope, which is fine here, but of order of events. If I read correctly, you instanciate the Twitter class with username and password variables before they are set/read, so with null values.

Hmm, im still trying to get a simple example to work. i tried out some of the examples posted here, and i get the same problems, "type status is ambigious" etc. etc. but none of them works. does anybody have a real basic, programm to just test it? Did I install it right? I copied the twitter4j-2.0.8.jar and all the other jars that were in the lib folder to the sketch code folder.
THX!

I read about this in this threat and a lot of people solved it. This is the whole code of one example that seems to work when used by others.
It still tells me "The type Status is Ambigious"

Could you maybe specify where i have to change something?
Thank you!

Code:

Twitter twitter;
String myTimeline;
User[] friends;
String username = "USERNAME"; // add your own here
String password = "PASSWORD"; // add your own here
java.util.List statuses = null;

twitter = new Twitter(username,password);
//java.util.List statuses = twitter.getUserTimeline();
try
{
 statuses = twitter.getUserTimeline(); 
}
catch( TwitterException e) 
{ 
 println(e.getStatusCode());
}
for( int i=0; i<statuses.size(); i++ )
{
   Status status = (Status)statuses.get(i);
   println(status.getUser().getName() + ":" + status.getText());
}

rename the jar file to the same name of your folder..

try folder name "twitter4j" and libname "twitter4j.jar"

im just telling you what i did when i tried it.. and your code compiles just fine here too..

that must be something about java ? are u using expert version of processing? just throwing out ideas, not sure whats going on

sorry to bother you again, now as it is working, i try to use what i was looking for. a simple query search. But im having a hard time converting this :

You can search for Tweets using Query class and Twitter.search(twitter4j.Query) method as following:

Twitter twitter = new Twitter();
Query query = new Query("source:twitter4j yusukey");
QueryResult result = twitter.search(query);
System.out.println("hits:" + result.getTotal());
for (Tweet tweet : result.getTweets()) {
System.out.println(tweet.getFromUser() + ":" + tweet.getText());
}

to processing code. Could you give me a hand on this? Would be great.

Thanks, that seems to work but i get stragnge results.

for example searching for ccc gives me only 1 result 6 days old...
using the twitter search : http://search.twitter.com/search?q=ccc
i get much more.

Also my hit counter always prints -1. so maybe there is an error somewhere?

As soon as i get on your nerves, let me know

Code:

Twitter twitter;
String myTimeline;
User[] friends;
String username = "UN"; // add your own here
String password = "PW"; // add your own here
//java.util.List result = null;




twitter = new Twitter(username,password);

//java.util.List statuses = twitter.getUserTimeline();
try
 {
   Query query = new Query("source:twitter4j  ccc");
   QueryResult result = twitter.search( query );
   System.out.println("hits:" + result.getTotal());

   java.util.List  tweets = result.getTweets();
   for( int i=0; i<tweets.size(); i++ )
   {
	 Tweet tweet = (Tweet)tweets.get( i );
	 System.out.println(tweet.getFromUser() + ":" + tweet.getText());
   }		  
 } catch (TwitterException te) {
     System.out.println("Failed to get queries: " + te.getMessage());
     System.exit( -1);
 }

hmm well the thing is in the query string..

you have "source:twitter4j ccc"

if you look at the results you will see from which client they tweet.

the source gives u results from the source.. so maybe no one is using twitter4j to post..

try :

"source:web ccc"

it will give you all results from tweets created on web..

you will need to find a way to search for all sources and sort them out.. or check the API to see how to do searches like the website.

or madly, just get a list of sources yourself and search them all, sort the results and show them =)

EDIT: i've just tested that, so don't take it for granted.. make some research, i might be wrong.

im an idiot

i didnt realize, that source:twitter4j limits it to messages posted from t4j. i thought it just has to be there as it is part of the library...just deleting the source part and just writing Query query = new Query("ccc"); does a good job, looks the same as the twitter web search. i still get a hits:-1 result but i hope that wont be a problem.
