I was looking for a simple Java example using the Twitter 1.1 API and couldn't find one. Using the PHP sample posted here: Simplest PHP example for retrieving user_timeline with Twitter API version 1.1 and a few other Stackoverflow posts, I was able to come up with the following working example.
public void testUserTimelineWithAuthSample() throws Exception {
//This will read the timeline of your account.
String method = "GET";
String url = "https://api.twitter.com/1.1/statuses/user_timeline.json";
String oAuthConsumerKey = "Your value here.";
String oAuthConsumerSecret = "Your value here."; //<--- DO NOT SHARE THIS VALUE
String oAuthAccessToken = "Your value here.";
String oAuthAccessTokenSecret = "Your value here."; //<--- DO NOT SHARE THIS VALUE
String oAuthNonce = String.valueOf(System.currentTimeMillis());
String oAuthSignatureMethod = "HMAC-SHA1";
String oAuthTimestamp = time();
String oAuthVersion = "1.0";
String signatureBaseString1 = method;
String signatureBaseString2 = url;
String signatureBaseString3Templ = "oauth_consumer_key=%s&oauth_nonce=%s&oauth_signature_method=%s&oauth_timestamp=%s&oauth_token=%s&oauth_version=%s";
String signatureBaseString3 = String.format(signatureBaseString3Templ,
oAuthConsumerKey,
oAuthNonce,
oAuthSignatureMethod,
oAuthTimestamp,
oAuthAccessToken,
oAuthVersion);
String signatureBaseStringTemplate = "%s&%s&%s";
String signatureBaseString = String.format(signatureBaseStringTemplate,
URLEncoder.encode(signatureBaseString1, "UTF-8"),
URLEncoder.encode(signatureBaseString2, "UTF-8"),
URLEncoder.encode(signatureBaseString3, "UTF-8"));
System.out.println("signatureBaseString: "+signatureBaseString);
String compositeKey = URLEncoder.encode(oAuthConsumerSecret, "UTF-8") + "&" + URLEncoder.encode(oAuthAccessTokenSecret, "UTF-8");
String oAuthSignature = computeSignature(signatureBaseString, compositeKey);
System.out.println("oAuthSignature : "+oAuthSignature);
String oAuthSignatureEncoded = URLEncoder.encode(oAuthSignature, "UTF-8");
System.out.println("oAuthSignatureEncoded: "+oAuthSignatureEncoded);
String authorizationHeaderValueTempl = "OAuth oauth_consumer_key=\"%s\", oauth_nonce=\"%s\", oauth_signature=\"%s\", oauth_signature_method=\"%s\", oauth_timestamp=\"%s\", oauth_token=\"%s\", oauth_version=\"%s\"";
String authorizationHeaderValue = String.format(authorizationHeaderValueTempl,
oAuthConsumerKey,
oAuthNonce,
oAuthSignatureEncoded,
oAuthSignatureMethod,
oAuthTimestamp,
oAuthAccessToken,
oAuthVersion);
System.out.println("authorizationHeaderValue: "+authorizationHeaderValue);
System.out.println("url: "+url);
System.out.println("authorizationHeaderValue:"+authorizationHeaderValue);
GetMethod getMethod = new GetMethod(url);
getMethod.addRequestHeader("Authorization", authorizationHeaderValue);
HttpClient cli = new HttpClient();
int status = cli.executeMethod(getMethod);
System.out.println("Status:"+status);
long responseContentLength = getMethod.getResponseContentLength();
System.out.println("responseContentLength:"+responseContentLength);
String response = getMethod.getResponseBodyAsString();
System.out.println("response: "+response);
}
private static String computeSignature(String baseString, String keyString) throws GeneralSecurityException, UnsupportedEncodingException, Exception
{
SecretKey secretKey = null;
byte[] keyBytes = keyString.getBytes();
secretKey = new SecretKeySpec(keyBytes, "HmacSHA1");
Mac mac = Mac.getInstance("HmacSHA1");
mac.init(secretKey);
byte[] text = baseString.getBytes();
return new String(Base64.encodeBase64(mac.doFinal(text))).trim();
}
private String time() {
long millis = System.currentTimeMillis();
long secs = millis / 1000;
return String.valueOf( secs );
}
However, if I add parameters to the url like:
String url = "https://api.twitter.com/1.1/statuses/user_timeline.json?screen_name=twitterapi&count=2";
I get:
response: {"errors":[{"message":"Could not authenticate you","code":32}]}
Any idea where this is going wrong?
This works excellent for Timeline with the new Twitter API 1.1
1) Download twitter4j-core-3.0.3.jar in http://twitter4j.org/en/
2) Try use this code:
private static final String TWITTER_CONSUMER_KEY = "xxxxxxxxxxxxxxxxxx";
private static final String TWITTER_SECRET_KEY = "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx";
private static final String TWITTER_ACCESS_TOKEN = "xxxxxxxxxxxxxxxxxxxxxxx";
private static final String TWITTER_ACCESS_TOKEN_SECRET = "xxxxxxxxxxxxxxxxxxxxxxxxx";
ConfigurationBuilder cb = new ConfigurationBuilder();
cb.setDebugEnabled(true)
.setOAuthConsumerKey(TWITTER_CONSUMER_KEY)
.setOAuthConsumerSecret(TWITTER_SECRET_KEY)
.setOAuthAccessToken(TWITTER_ACCESS_TOKEN)
.setOAuthAccessTokenSecret(TWITTER_ACCESS_TOKEN_SECRET);
TwitterFactory tf = new TwitterFactory(cb.build());
Twitter twitter = tf.getInstance();
try {
Query query = new Query("MrEdPanama");
QueryResult result;
do {
result = twitter.search(query);
List<Status> tweets = result.getTweets();
for (Status tweet : tweets) {
System.out.println("#" + tweet.getUser().getScreenName() + " - " + tweet.getText());
}
} while ((query = result.nextQuery()) != null);
System.exit(0);
} catch (TwitterException te) {
te.printStackTrace();
System.out.println("Failed to search tweets: " + te.getMessage());
System.exit(-1);
}
You are wrong with the oauth_nonce. It is a random 32 bytes string encoded in base 64.
You can build them like this :
public String generateNonce() {
Random gen = new Random(System.currentTimeMillis());
StringBuilder nonceBuilder = new StringBuilder("");
String base = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ";
int baseLength = base.length();
// Taking random word characters
for (int i = 0; i < 32; ++i) {
int position = gen.nextInt(baseLength);
nonceBuilder.append(base.charAt(position));
}
String nonce = toBase64(nonceBuilder.toString());
return nonce;
}
// In your code :
String oAuthNonce = generateNonce();
With String toBase64(String); which is a method to encode a String with Base 64.
Here's a Twitter 1.1 API example that works with parameters. The issue was not related to the nonce. It was the signatureBaseString. Think of the signatureBaseString as a 3 part string delimited by the ampersand (METHOD&URL&PARAMS). The api parameters are NOT to be included in the 2nd part of the signatureBaseString, they are to be included (with the other 6 security parameters) in the last part of signatureBaseString (Also, those params must be in alphabetic order).
public void testUserTimelineWithParams() throws Exception {
//This will read the timeline of the 'twitterapi' account.
String method = "GET";
String url = "https://api.twitter.com/1.1/statuses/user_timeline.json";

Where the NvpComparator is:

String name1 = arg1.getName();
return name0.compareTo(name1);
}

Here is my solution using twitter4j lib
Twitter twitter = new TwitterFactory().getInstance();
AccessToken accessToken = new AccessToken(accessTokenStr, accessTokenSecretStr);
twitter.setOAuthConsumer(consumerKeyStr, consumerSecretStr);
twitter.setOAuthAccessToken(accessToken);
try {
Query query = new Query("#<HASHTAG TO SEARCH>");
QueryResult result;
result = twitter.search(query);
List<Status> tweets = result.getTweets();
for (Status tweet : tweets) {
System.out.println("#" + tweet.getUser().getScreenName() + " - " + tweet.getText());
}
}
catch (TwitterException te) {
te.printStackTrace();
System.out.println("Failed to search tweets: " + te.getMessage());
System.exit(-1);
}

I'm trying to modify the TestSets property of a TestCase.
JsonArray newTestSets = new JsonArray();
... add values as needed ( in the simplest case I'm clearing the property )
JsonObject updates = new JsonObject();
updates.add("TestSets", newTestSets);
I create the updateRequest like I do for all other updates
UpdateRequest updateRequest = new UpdateRequest(ref, updates)
I don't get any error but nothing has changed. The TestCase is still in several TestSets
What am I missing?
I verified that it works to update TestSets collection on a TestCase. See this github repo.

I am trying to create a dynamic md5 hash system for authenticating to the Marvel API.
I create a timestamp variable, add the private / public key and then try and turn that into a md5 hash. When I print out the results, the timestamp in the url and the timestamp in the string to be hashed becomes different.
//I declare the timestamp here
Long tsLong = System.currentTimeMillis()/1000;
final String ts = tsLong.toString();
//Create the string to be hashed
final String toHash = ts + privateKey + publicKey;
url = "" + publicKey;
String hash = new String();
//my hashing algorithm
try {
MessageDigest md = MessageDigest.getInstance("MD5");
byte[] hashe = md.digest(toHash.getBytes("UTF-8"));
StringBuffer hex = new StringBuffer(2*hashe.length);
for (byte b : hashe) {
hex.append(String.format("%02x", b&0xff));
}
hash = hex.toString();
}
catch(NoSuchAlgorithmException e) {
}
catch(UnsupportedEncodingException e) {
}
//append the url to include the hash
url += "&hash=";
url += hash;
//call the api
RequestQueue queue = VolleySingleton.getInstance().getRequestQueue();
JsonObjectRequest obj = new JsonObjectRequest
(Request.Method.GET,
url,
null,

So as you can see: the url ts and the toHash have different values. Why is this?
I am a fool. I was hard coding the ts into my url, instead of updating it by adding the generated ts.
i am using following piece of code to query for workspace. But apparently, if the workspace is not set as default, this query fails.
How can I successfully query for a workspace which is not my default workspace?
Thanks.

System.out.println("Workspace found.");
}catch (IndexOutOfBoundsException e){

Since by default Rally REST queries are workspace-scoped, to obtain an enumeration of Workspaces, you need to query the Subscription object and then pull its Workspace collection.
Here's a quick example:
public class RestExample_QueryWorkspacesAndProjects {
public static void main(String[] args) throws URISyntaxException, IOException {
// Create and configure a new instance of RallyRestApi
// Connection parameters
String rallyURL = "https://rally1.rallydev.com";

String applicationName = "RestExample_QueryWorkspacesAndProjects";
// Credentials
String userName = "user#company.com";
String userPassword = "topsecret";
RallyRestApi restApi = new RallyRestApi(
new URI(rallyURL),
userName,
userPassword);
restApi.setWsapiVersion(wsapiVersion);
restApi.setApplicationName(applicationName);
//Read Subscription
QueryRequest subscriptionRequest = new QueryRequest("Subscriptions");
subscriptionRequest.setFetch(new Fetch("Name", "SubscriptionID", "Workspaces", "Name"));
QueryResponse subscriptionQueryResponse = restApi.query(subscriptionRequest);
JsonArray subscriptionQueryResults = subscriptionQueryResponse.getResults();
JsonElement subscriptionQueryElement = subscriptionQueryResults.get(0);
JsonObject subscriptionQueryObject = subscriptionQueryElement.getAsJsonObject();
String subID = subscriptionQueryObject.get("SubscriptionID").toString();
System.out.println("Read Subscription: " + subID);
// Grab Workspaces Collection
JsonArray myWorkspaces = subscriptionQueryObject.get("Workspaces").getAsJsonArray();
// Initialize Project counter
int numberProjects = 0;
for (int i=0; i<myWorkspaces.size(); i++) {
JsonObject workspaceObject = myWorkspaces.get(i).getAsJsonObject();
String workspaceRef = workspaceObject.get("_ref").getAsString();
GetRequest workspaceRequest = new GetRequest(workspaceRef);
workspaceRequest.setFetch(new Fetch("Name", "Projects"));
GetResponse workspaceResponse = restApi.get(workspaceRequest);
JsonObject workspaceObj = workspaceResponse.getObject();
String workspaceName = workspaceObj.get("Name").getAsString();
System.out.printf("Workspace %d ==> %s\n", i, workspaceName);
JsonArray myProjects = workspaceObj.get("Projects").getAsJsonArray();
for (int j=0; j<myProjects.size(); j++)
{
JsonObject projectObject = myProjects.get(j).getAsJsonObject();
String projectRef = projectObject.get("_ref").getAsString();
GetRequest projectRequest = new GetRequest(projectRef);
projectRequest.setFetch(new Fetch("Name"));
GetResponse projectResponse = restApi.get(projectRequest);
JsonObject projectObj = projectResponse.getObject();
String projectName = projectObj.get("Name").getAsString();
System.out.printf("==> Project %d ==> %s\n", j, projectName);
numberProjects++;
}
}
String numberWorkspacesStr = String.valueOf(myWorkspaces.size());
String numberProjectsStr = String.valueOf(numberProjects);
System.out.println("Total Workspaces: " + numberWorkspacesStr);
System.out.println("Total Projects: " + numberProjectsStr);
restApi.close();
}
