Get Twitter Friends List

Get twitter friends list?

In Swift 4.2, Xcode 10.1 and iOS 12.1

Finally i got the solution for this. Here first we need Authorisation then need to implement friends list api.

Pure Swift code is not available. But i implemented in pure swift.

If you want to get friends/list data from twitter you need to use two API's.

1) oauth2/token API

2) friends/list API

In oauth2/token api you can get access token, because you need access token for friends list. And you need user id, screen name.

But here you must remember one important point.

1) First use oauth2/token api for access token.

2) After getting access token use twitter login api for user id and screen name.

3) Now use friends/list api.

Here first if you use twitter login then oauth2/token api for access token, you can get like Bad Authentication data error. So you please follow above 3 steps in order.

1) Get access token code (oauth2/token api):

func getAccessToken() {

    //RFC encoding of ConsumerKey and ConsumerSecretKey
    let encodedConsumerKeyString:String = "sx5r...S9QRw".addingPercentEncoding(withAllowedCharacters: CharacterSet.urlHostAllowed)!
    let encodedConsumerSecretKeyString:String = "KpaSpSt.....tZVGhY".addingPercentEncoding(withAllowedCharacters: CharacterSet.urlHostAllowed)!
    print(encodedConsumerKeyString)
    print(encodedConsumerSecretKeyString)
    //Combine both encodedConsumerKeyString & encodedConsumerSecretKeyString with " : "
    let combinedString = encodedConsumerKeyString+":"+encodedConsumerSecretKeyString
    print(combinedString)
    //Base64 encoding
    let data = combinedString.data(using: .utf8)
    let encodingString = "Basic "+(data?.base64EncodedString())!
    print(encodingString)
    //Create URL request
    var request = URLRequest(url: URL(string: "https://api.twitter.com/oauth2/token")!)
    request.httpMethod = "POST"
    request.setValue(encodingString, forHTTPHeaderField: "Authorization")
    request.setValue("application/x-www-form-urlencoded;charset=UTF-8", forHTTPHeaderField: "Content-Type")
    let bodyData = "grant_type=client_credentials".data(using: .utf8)!
    request.setValue("\(bodyData.count)", forHTTPHeaderField: "Content-Length")
    request.httpBody = bodyData

    let task = URLSession.shared.dataTask(with: request) { data, response, error in guard let data = data, error == nil else { // check for fundamental networking error
        print("error=\(String(describing: error))")
        return
        }

        let responseString = String(data: data, encoding: .utf8)
        let dictionary = data
        print("dictionary = \(dictionary)")
        print("responseString = \(String(describing: responseString!))")

        if let httpStatus = response as? HTTPURLResponse, httpStatus.statusCode != 200 { // check for http errors
            print("statusCode should be 200, but is \(httpStatus.statusCode)")
            print("response = \(String(describing: response))")
        }

        do {
            let response = try JSONSerialization.jsonObject(with: data, options: []) as! Dictionary<String, Any>
            print("Access Token response : \(response)")
            print(response["access_token"]!)
            self.accessToken = response["access_token"] as! String

            self.getStatusesUserTimeline(accessToken:self.accessToken)

        } catch let error as NSError {
            print(error)
        }
    }

    task.resume()
}

Output :

{"token_type":"bearer","access_token":"AAAAAAAAAAAAAAAAAAA............xqT3t8T"}

2) Login with twitter code

@IBAction func onClickTwitterSignin(_ sender: UIButton) {

    //Login and get session
    TWTRTwitter.sharedInstance().logIn { (session, error) in

        if (session != nil) {
            //Read data
            let name = session?.userName ?? ""
            print(name)
            print(session?.userID  ?? "")
            print(session?.authToken  ?? "")
            print(session?.authTokenSecret  ?? "")

             // self.loadFollowers(userid: session?.userID ?? "")

            //Get user email id
            let client = TWTRAPIClient.withCurrentUser()
            client.requestEmail { email, error in
                if (email != nil) {
                    let recivedEmailID = email ?? ""
                    print(recivedEmailID)
                } else {
                    print("error--: \(String(describing: error?.localizedDescription))");
                }
            }
            //Get user profile image url's and screen name
            let twitterClient = TWTRAPIClient(userID: session?.userID)
            twitterClient.loadUser(withID: session?.userID ?? "") { (user, error) in
                print(user?.profileImageURL ?? "")
                print(user?.profileImageLargeURL ?? "")
                print(user?.screenName ?? "")
            }



            let storyboard = self.storyboard?.instantiateViewController(withIdentifier: "SVC") as! SecondViewController
            self.navigationController?.pushViewController(storyboard, animated: true)
        } else {
            print("error: \(String(describing: error?.localizedDescription))");
        }
    }

}

Output:

Here you will get userName, userId, authtoken, authTokenSecret, screen name and email etc.

3) Now get friends list from friends/list api. Here you can get friends/list, users/lookup, followers/ids, followers/list api's data etc...

func getStatusesUserTimeline(accessToken:String) {

    let userId = "109....456"
    let twitterClient = TWTRAPIClient(userID: userId)
    twitterClient.loadUser(withID: userId) { (user, error) in
        if user != nil {
            //Get users timeline tweets
            var request = URLRequest(url: URL(string: "https://api.twitter.com/1.1/friends/list.json?screen_name=KS....80&count=10")!) //users/lookup, followers/ids, followers/list 
            request.httpMethod = "GET"
            request.setValue("Bearer "+accessToken, forHTTPHeaderField: "Authorization")

            let task = URLSession.shared.dataTask(with: request) { data, response, error in guard let data = data, error == nil else { // check for fundamental networking error
                print("error=\(String(describing: error))")
                return
                }

      //                    let responseString = String(data: data, encoding: .utf8)
      //                    let dictionary = data
      //                    print("dictionary = \(dictionary)")
      //                    print("responseString = \(String(describing: responseString!))")

                if let httpStatus = response as? HTTPURLResponse, httpStatus.statusCode != 200 { // check for http errors
                    print("statusCode should be 200, but is \(httpStatus.statusCode)")
                    print("response = \(String(describing: response))")
                }

                do {
                    let response = try JSONSerialization.jsonObject(with: data, options: [])
                    print(response)

                } catch let error as NSError {
                    print(error)
                }
            }

            task.resume()

        }
    }

}

This code not available any where. I tried a lot for this code and i spent lot of time for this. Thank you.

How to get Twitter Friends List?

Use this library, you can easily achieve that

Full list of twitter friends using python and tweepy

According to the source code, friends() is referred to the GET friends / list twitter endpoint, which allows a count parameter to be passed in:

The number of users to return per page, up to a maximum of 200. Defaults to 20.

This would allow you to get 200 friends via friends().

Or, better approach would be to use a Cursor which is a paginated way to get all of the friends:

for friend in tweepy.Cursor(api.friends).items():
    # Process the friend here
    process_friend(friend)

How to get list of all twitter followers using twitter4j?

Just Change like this and try, this is working for me

    try {
        Log.i("act twitter...........", "ModifiedCustomTabBarActivity.class");
        // final JSONArray twitterFriendsIDsJsonArray = new JSONArray();
        IDs ids = mTwitter.mTwitter.getFriendsIDs(-1);// ids
        // for (long id : ids.getIDs()) {
        do {
            for (long id : ids.getIDs()) {               


                String ID = "followers ID #" + id;
                String[] firstname = ID.split("#");
                String first_Name = firstname[0];
                String Id = firstname[1];

                Log.i("split...........", first_Name + Id);

                String Name = mTwitter.mTwitter.showUser(id).getName();
                String screenname = mTwitter.mTwitter.showUser(id).getScreenName();


  //            Log.i("id.......", "followers ID #" + id);

How to get the Twitter followers count using Twitter API (in 2022)?

Yes, there is a simple way to do this using the Twitter API v2!

The follower and following counts for a user are part of the public_metrics fields in the User object.

The API endpoint and parameters are in the format

https://api.twitter.com/2/users/[ID]?user.fields=public_metrics,[any other fields]

Here's an example of the output, using the twurl command line tool (which handles the authentication etc, you may need to use a library to help with OAuth):

$ twurl -j "/2/users/786491?user.fields=public_metrics,created_at"
{
  "data": {
    "id": "786491",
    "username": "andypiper",
    "created_at": "2007-02-21T15:14:48.000Z",
    "name": "andypiper.xyz",
    "public_metrics": {
      "followers_count": 16570,
      "following_count": 3247,
      "tweet_count": 134651,
      "listed_count": 826
    }
  }
}
