Get current user's info from Twitter API

Question

I am building a Twitter app (with oAuth) and I cannot find any info on how I can get the current user's info.

By current user, I mean the user which granted my app permissions and for whom the app is making the requests to the API.

Any suggestions?

Link to the documentation for API v. 1.1: https://dev.twitter.com/docs/api/1.1/get/account/verify_credentials

Using oAuth you are able to make calls to get user info from your TwitterOAuth object.

e.g if

$oauth = new TwitterOAuth([keys here]);

$credentials = $oauth->get('account/verify_credentials');

echo "Connected as @" . $credentials->screen_name ."\n";

Solution respecting iOS:

1) If you have a Twitter account (i.e. ACAccount from ACAccountStore) on your device, the only thing you need is to attach it to SLRequest and get all the user info from the returned dictionary:

NSURL *url = [NSURL URLWithString:@"https://api.twitter.com/1.1/account/verify_credentials.json"];
NSMutableDictionary *params = [NSMutableDictionary new];
[params setObject:[Twitter sharedInstance].session.userID forKey:@"user_id"];
[params setObject:@"0" forKey:@"include_entities"];
[params setObject:@"1" forKey:@"skip_status"];
[params setObject:@"1" forKey:@"include_email"];

SLRequest *request = [SLRequest requestForServiceType:SLServiceTypeTwitter requestMethod:SLRequestMethodGET URL:url parameters:params];
[request setAccount:twitterAccount]; //one of the Twitter Acc
[request performRequestWithHandler:^(NSData *responseData, NSHTTPURLResponse *urlResponse, NSError *error) {
    if (responseData) {
        NSDictionary *twitterData = [NSJSONSerialization JSONObjectWithData:responseData options:NSJSONReadingAllowFragments error:NULL];
        });

    }else {
        NSLog(@"Error while downloading Twitter user data: %@", error);
    }
}];

2) Otherwise - you need to send OAuth (X-Auth) user credentials. The easiest way is to use TWTROAuthSigning class to retrieve OAuth-params:

TWTROAuthSigning *oauthSigning =
                         [[TWTROAuthSigning alloc]
                          initWithAuthConfig:
                          [Twitter sharedInstance].authConfig
                          authSession:session];
                         NSDictionary *authHeaders =
                         [oauthSigning OAuthEchoHeadersToVerifyCredentials];

and than send the ordinary request attaching credentials as header fields:

  NSString *oauthParameters = authHeaders[@"X-Verify-Credentials-Authorization"];
                         NSString *urlString = authHeaders[@"X-Auth-Service-Provider"];
                         NSMutableURLRequest *request =
                         [NSMutableURLRequest requestWithURL:[NSURL URLWithString:urlString]];
                         request.allHTTPHeaderFields = @{@"Authorization":oauthParameters};
                         [request setHTTPMethod:@"GET"];
                         NSOperationQueue *queue = [[NSOperationQueue alloc]init];
                         [NSURLConnection sendAsynchronousRequest:request queue:queue completionHandler:^(NSURLResponse *response,NSData *data,NSError *error){
                              NSDictionary *twitterData = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingAllowFragments error:NULL];
                         }];

If you support an old version of Twitter SDK or searching for more options I'd recommend to look at STTwitter lib

It was actually "account/verify_credentials" as seen here:
