ofxTwitterstream example > doesn't work

beginners
#1

hei,
I’m trying to fetch tweets with a certain hashtag. I ran into the ofxTwitterstream addon but when trying to run the example I am confused what’s going wrong. I used a couple of very common hashtags but it doesn’t return anything. I’m not even sure if the login is successful or anything.
can anyone help?

//--------------------------------------------------------------
void testApp::setup(){
	ofBackground(33,33,33);
	ofSetFrameRate(60);
	ofSetVerticalSync(true);
	
	twitter.connect(
		"my username"
		,"my pw"
		,"stream.twitter.com"
		,"/1/statuses/filter.json?track=#photography"
	);
}

//--------------------------------------------------------------
void testApp::update(){
	ofSetWindowTitle(ofToString(ofGetFrameRate()));
	while(twitter.hasNewTweets()) {
		ofxTweet t = twitter.getNextTweet();
        printf("text %s", t.getText().c_str());
		cout << "avatar:" << t.getAvatar() << endl;
		cout << "---" << endl;
	}
}

I’ve actually started trying this before I posted the question but I cannot get the search example to work either.
is there a way to check if twitterClient.authorize(CONSUMER_KEY, CONSUMER_SECRET); is successful or not? the search example loads from cached file (twitterClient.loadCacheFile();) but not even the simple search // Simple Query. You can find tweets containing that word. ofxTwitterSearch search; search.query = "cat"; twitterClient.startSearch(search);

It works fine for me. Are you sure that you put the right keys? if the app is authorized a new browser page will open and you will redirect to the twitter server asked to authorize your application. After that it will stored in bin/data folder a credentials.xml file for the next use of your app. I think you can query if the app is auhorized with

bool ofxTwitter::isAuthorized()

but maybe @pelayo can give some more hints on it.

I entered a new app into dev.twitter.com and copypasted the codes. however, for me the openframeworks app doesn’t open a browser page which redirects to twitter… is that what you meant should happen?
here are my error messages logged to the console:

    [notice ] ofxTwitter::authorize: Authorizing app...
[notice ] ofxOAuth::loadCredentials: Unable to locate credentials file: ../../../data/credentials.xml

i had a similar issue before see here but no remember well what was the reason (maybe the wrong keys or i missed to put some files in /data folder) do you create the app from scratch or are you testing the example?

#7

indeed. the data folder is missing that credentials file. I’m trying to get the example to work…
and about the link: I’m checking the readme file now. at least the link says that the credentials file is created automatically after first authorization. I don’t get to that authorization is my problem…

Hi @suse_m Have yo specified a callback url on the Twitter side, any URL will work.

Hi @pelayo do you know if the addon still works? Im getting the same error like @suse_m

[notice ] ofxTwitter::authorize: Authorizing app...
[notice ] ofxOAuth::loadCredentials: Unable to locate credentials file: ../../../data/credentials.xml
ERROR: \200
[warning] ofxOAuth::obtainRequestToken: Return parameter did not have 2 values: <html>\n<head>\n<meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>\n<title>Error 401 Unauthorized</title>
</head>
<body>
<h2>HTTP ERROR: 401</h2>
<p>Problem accessing '/oauth/request_token?'. Reason:
<pre>    Unauthorized</pre>
</body>
</html>
 - skipping.

And i set an url in the twitter callback in the twitter side…

Best!
