I saw related posts and it didn't help me with this issue.
Below is the code and am getting IllegalStateException, Authentication credentials are missing.
Please help me with this error.
ConfigurationBuilder cb = new ConfigurationBuilder();
cb.setDebugEnabled(true)
.setOAuthConsumerKey("XXXX")
.setOAuthConsumerSecret("XXXXX")
.setOAuthAccessToken("XXXX")
.setOAuthAccessTokenSecret("XXXX");
TwitterFactory tf = new TwitterFactory(cb.build());
Twitter twitter = tf.getSingleton();
Query query = new Query("source:twitter4j sample");
QueryResult result = null;
result = twitter.search(query); //error occurs in this line
for (Status status : result.getTweets()) {
System.out.println("#" + status.getUser().getScreenName() + ":" + status.getText());
}
You code is fine , just one mistake you did in this line ,
Twitter twitter = tf.getSingleton();
The configuration object you provided won't be set in the singleton ,unless you use getInstance() method, so use this
Twitter twitter = tf.getInstance();

I'm struggling to connect to the Facebook Messenger API. The server keeps returning:
The remote server returned an error: (400) Bad Request.
I've been at this for a few days, tried multiple methods, even tried a few VS packages that don't quite work. I've checked my Auth Token several times, and I don't know what else it might be.
Is there something obvious that's causing a bad request? I've copied the root URL from Facebook's API page. The token in the code below has been removed. The application throws an exception when I attempt to read the response. (WebResponse FBresponse = FBrequest.GetResponse();)
private string FBSendMessage(string user, string message)
{
string result = null;
string FBroot = "https://graph.facebook.com/v2.6/me/messages?access_token=";
string token = "EAA...DZD";
string FBURI = FBroot + token;
string FBstring = "{ \"recipient\": { \"id\":\"" + user + "\" }, \"message\": { \"text\":\"" + message + "\" } }";
try
{
//using (WebClient FBclient = new WebClient())
//{
// result =
// FBclient.UploadString(FBURI, FBstring);
//}
HttpWebRequest FBrequest = (HttpWebRequest)WebRequest.Create(FBURI);
FBrequest.Credentials = CredentialCache.DefaultCredentials;
FBrequest.ProtocolVersion = HttpVersion.Version11;
FBrequest.Method = "POST";
FBrequest.ContentType = "application/json";
byte[] FBbytes = Encoding.UTF8.GetBytes(FBstring);
FBrequest.ContentLength = FBbytes.Length;
Stream FBstream = FBrequest.GetRequestStream();
FBstream.Write(FBbytes, 0, FBbytes.Length);
FBstream.Close();
WebResponse FBresponse = FBrequest.GetResponse();
Output((((HttpWebResponse)FBresponse).StatusDescription), Log.Error);
FBstream = FBresponse.GetResponseStream();
StreamReader FBreader = new StreamReader(FBstream);
result = FBreader.ReadToEnd();
FBreader.Close();
FBresponse.Close();
}
catch(Exception ex)
{
Output(ex.Message, Log.Error);
}
return result;
}
I have determined that my code isn't the issue. The issue is that I'm making a request with an invalid user id. Facebook creates a user ID in the application context that isn't the same as your default user id. I have to receive a message to learn that contextualized id before I can send a message.
I'm trying to change Box folder collaboration type for user from salesforce Apex trigger. The first thoughts were to use box.Toolkit but it looks like this class does not have updateCollaboration or changeCollaboration method, only create. I guess my only option is to use Box's Rest API. Is there any way I can get service account token in Apex so I can use it in a callout?
I have created a special "Tokens" object in Salesforce with two fields: access token and refresh token. I then have a batch job that runs to update the access token every 55 minutes such that they never expired.
Here is a code snippet in APEX using the Tokens object.
#future(callout=true)
public static void updateTokens(){
//app info for authenticating
String clientID = 'MY_CLIENT_ID';
String clientSecret = 'MY_CLIENT_SECRET';
//look up value of existing refresh token
Token__c myToken = [SELECT Name, Value__c FROM Token__c WHERE Name='Refresh'];
Token__c myAccessToken = [SELECT Name, Value__c FROM Token__c WHERE Name='Access'];
String refreshToken = myToken.Value__c;
String accessToken = myAccessToken.Value__c;
//variables for storing data
String BoxJSON = '';
String debugTxt = '';
//callout to Box API to get new tokens
HttpRequest reqRefresh = new HttpRequest();
reqRefresh.setMethod('POST');
String endpointRefresh = 'https://www.box.com/api/oauth2/token';
reqRefresh.setEndpoint(endpointRefresh);
String requestBody = ('grant_type=refresh_token&refresh_token=' + refreshToken + '&client_id=' + clientID + '&client_secret=' + clientSecret);
reqRefresh.setBody(requestBody);
System.debug('Body of refresh request: ' + requestBody);
//Create Http, send request
Http httpRefresh = new Http();
Boolean successRefresh = false;
while (successRefresh == false){
try{
HTTPResponse resRefresh = httpRefresh.send(reqRefresh);
BoxJSON = resRefresh.getBody();
System.debug('Body of refresh response: ' + BoxJSON);
successRefresh = true;
}
catch (System.Exception e){
System.debug('Error refreshing: ' + string.valueof(e));
if (Test.isRunningTest()){
successRefresh = true;
}
}
}
Keep in mind that if you are using the Box for Salesforce integration your administrator can set the option for the permissions on the folders to sync with Salesforce permissions. This would reverse any changes you make to collaborations. Check out more about Box's Salesforce integration permissions here: https://support.box.com/hc/en-us/articles/202509066-Box-for-Salesforce-Administration#BfS_admin_perm
I have a problem when trying to post on my own business time line on facebook.
I get an error that says:
"(OAuthException)(#200) The user hasn't authorized the application to perform this action"
I think this has to do with the scope "publish_actions" in somehow but how can I authorize this publish_actions permission exactly?
I have looked everywhere in my account under "https://developers.facebook.com"
I have put my App for review but I cant add "publish_actions" as a permission for Facebook to review because on this permission there is a message which says: "It looks like you haven't made any API requests to access content with the publish_actions permission in the last 30 days"
But how can I use this permission without having the permission??
I would be very greatful for help if I am on the right track and what I am missing out?
Thank you!
try
{
String appID = "12345";
String appSecret = "123456";
String accessToken = "123|1234_a-b";
String clientToken = "1234567";
String pageID = "123456789";
Facebook.FacebookClient client = new Facebook.FacebookClient(accessToken);
var dicParams = new Dictionary<string, object>();
dicParams["message"] = "Hello on the time line message!";
dicParams["caption"] = string.Empty;
dicParams["description"] = string.Empty;
dicParams["name"] = "Some Name";

dicParams["access_token"] = accessToken;
var publishResponse = client.Post("/" + pageID + "/feed", dicParams);
MessageBox.Show("You posted on the timeline successfully!");
}
catch (Exception ex)
{ MessageBox.Show(ex.ToString()); }
Attempt 2:
I was looking at the facebook documentation and found an URL which seems relevant to post a message on the business page timeline:
POST graph.facebook.com/{user-id}/feed?message={message}&access_token={access-token}
I have tried to put it down in code like below but again, I receive the same error message:
(OAuthException)(#200) The user hasn't authorized the application to perform this action
Question is what I do wrong. Do I need to get any other access token with "publish_action" permission?. If that is the case I can't figure out how to get such token?
String appID = "12345";
String appSecret = "123456";
String accessToken = "123|1234_a-b";
String clientToken = "1234567";
String pageID = "123456789";
String message = "Hello World";
String requestUrl = "https://graph.facebook.com/" + pageID + "/feed?message=" + message + "&access_token=" + accessToken;
RestSharp.RestClient rc = new RestSharp.RestClient();
RestSharp.RestRequest request = new RestSharp.RestRequest(requestUrl, RestSharp.Method.POST);
request.AddHeader("Content-Type", "application/json");
request.AddHeader("x-li-format", "json");
request.RequestFormat = RestSharp.DataFormat.Json;
RestSharp.RestResponse restResponse = (RestSharp.RestResponse)rc.Execute(request);
RestSharp.ResponseStatus responseStatus = restResponse.ResponseStatus;
//"(OAuthException)(#200) The user hasn't authorized the application to perform this action"
MessageBox.Show(restResponse.Content.ToString());
I have found a solution which works. This code do post a "Message" to the timeline.
Question This code works for my business page. I also like to post on my personal page for friends. So tried to change the pageID to the the ID which is my personal page: (pageID = "987654321") but still it posts on my business page.
I wonder if I need to get a page token specifically for the personal page as well?
If that is the case, I wonder how this token can be achieved?
/*********************************************************************************************************************************************************************/
//STEPS!!! to get a non-expiring page access token:
//1. access the following URL and note the returned access token within the browser's address bar:

I succeeded to get every credentials(Oauth_token,Oauth_verifier).
With it, I tried to post a text to twitter account, but it always fail with error message "No authentication challenges found"
I found some solution like
"Check the time zone automatically",
"import latest twitter4j library" etc..
but after check it, still not work.
Is there anyone can show me the way.
code is like below
public static void updateStatus(final String pOauth_token,final String pOauth_verifier) {
new Thread() {
public void run() {
Looper.prepare();
try {
TwitterFactory factory = new TwitterFactory();
AccessToken accessToken = new AccessToken(pOauth_token,pOauth_verifier);
Twitter twitter = factory.getInstance();
twitter.setOAuthConsumer(Cdef.consumerKey, Cdef.consumerSecret);
twitter.setOAuthAccessToken(accessToken);
if (twitter.getAuthorization().isEnabled()) {
Log.e("btnTwSend","인증값을 셋팅하였고 API를 호출합니다.");
Status status = twitter.updateStatus(Cdef.sendText + " #" + String.valueOf(System.currentTimeMillis()));
Log.e("btnTwSend","status:" + status.getText());
}
} catch (Exception e) {
Log.e("btnTwSend",e.toString());
}
};
}.start();
}
"No authentication challenges found"
I think you are missing Access token secret in your code. That is why you are getting this exception.
Try following :
ConfigurationBuilder configurationBuilder;
Configuration configuration;
// Set the proper configuration parameters
configurationBuilder = new ConfigurationBuilder();
configurationBuilder
.setOAuthConsumerKey(TWITTER_CONSUMER_KEY);
configurationBuilder
.setOAuthConsumerSecret(TWITTER_CONSUMER_SECRET);
// Access token
configurationBuilder.setOAuthAccessToken(ACCESS_TOKEN);
// Access token secret
configurationBuilder
.setOAuthAccessTokenSecret(ACCESS_TOKEN_SECRET);
// Get the configuration object based on the params
configuration = configurationBuilder.build();
// Pass it to twitter factory to get the proprt twitter instance.
twitterFactory = new TwitterFactory(configuration);
twitter = twitterFactory.getInstance();
// use this instance to update
twitter.updateStatus("Your status");
I finally found the reason.
I thought parameter named 'oauth_token' , 'oauth_verifier' is member of accesstoken,
but it was not true.
I just had to pass one more way to get correct key.
and this way needs 'oauth_token' , 'oauth_verifier' to get accesstoken.
This code must add one more code below:
mAccessToken = mTwitter.getOAuthAccessToken(REQUEST_TOKEN,OAUTH_VERIFIER);
I want to update the facebookpage using c# sdk. I have partially successful with this, the problem is whenever I post messages to the page, post is visible only for admin(i am the admin of the page)is logged In. I want the post or feed to be visible to every one who visit the page.
(even admin is logged out post's are not visible to admin also)
The following code i am trying to achieve
public ActionResult FacebookPagePost()
{
string app_id = "xxxx";
string app_secret = "xxx";
string scope = "publish_stream,manage_pages";
string page_Id = "xxX";
if (Request["code"] == null)
{
return Redirect(string.Format(
"https://graph.facebook.com/oauth/authorize?client_id={0}&redirect_uri={1}&scope={2}",
app_id, Request.Url.AbsoluteUri, scope));
}
else
{
try
{
Dictionary<string, string> tokens = new Dictionary<string, string>();
string url = string.Format("https://graph.facebook.com/oauth/access_token?client_id={0}&redirect_uri={1}&scope={2}&code={3}&client_secret={4}",
app_id, Request.Url.AbsoluteUri, scope, Request["code"].ToString(), app_secret);
HttpWebRequest request = WebRequest.Create(url) as HttpWebRequest;
using (HttpWebResponse response = request.GetResponse() as HttpWebResponse)
{
StreamReader reader = new StreamReader(response.GetResponseStream());
string vals = reader.ReadToEnd();
foreach (string token in vals.Split('&'))
{
tokens.Add(token.Substring(0, token.IndexOf("=")),
token.Substring(token.IndexOf("=") + 1, token.Length - token.IndexOf("=") - 1));
}
}
string access_token = tokens["access_token"];
var client = new FacebookClient(access_token);
dynamic fbAccounts = client.Get("/me/accounts");
dynamic messagePost = new ExpandoObject();
messagePost.picture = "http://pic.com/pic.png";
messagePost.link = "http://www.examplearticle.com";
messagePost.name = "name goes here";
messagePost.description = "description goes here";
//Loop over the accounts looking for the ID that matches your destination ID (Fan Page ID)
foreach (dynamic account in fbAccounts.data) {
if (account.id == page_Id)
{
//When you find it, grab the associated access token and put it in the Dictionary to pass in the FB Post, then break out.
messagePost.access_token = account.access_token;
break;
}
}
client.Post("/" + page_Id + "/feed", messagePost);
}
catch (FacebookOAuthException ex)

}
catch (Exception e)
{
}
}

1) Create a Facebook App at: developers.facebook.com and get yourself an APPID and APPSECRET. (there are a lot of tutorials online for doing this so I will skip repeating it)
2) Go to: http://developers.facebook.com/tools/explorer and choose your app from the dropdown and click "generate access token".
3) After that do the following steps here:
https://stackoverflow.com/questions/17197970/facebook-permanent-page-access-token to get yourself a permanent page token.
(I can not stress this enough, follow the steps carefully and thoroughly)*
*I have tool I built that does this for me, all I enter is the APPID, APPSECRET and ACCESSTOKEN which the tool then generates a permanent page token for me. Anyone is welcomed to use it and help make it better,
https://github.com/devfunkd/facebookpagetokengenerator
=========================================================================
Ok at this point you should have your APPID, APPSECRET and a PERMANENT PAGE TOKEN.
=========================================================================
In your Visual Studio solution:
4) Using Nuget:Install-Package Facebook
5) Implement the Facebook client:
public void PostMessage(string message)
{
try
{
var fb = new FacebookClient
{
AppId = ConfigurationManager.AppSettings.Get("FacebookAppID"),
AppSecret = ConfigurationManager.AppSettings.Get("FacebookAppSecret"),
AccessToken = ConfigurationManager.AppSettings.Get("FacebookAccessToken")
};
dynamic result = fb.Post("me/feed", new
{
message = message
});
}
catch (Exception exception)
{
// Handle your exception
}
}
I hope this helps anyone who is struggling to figure this out.
