php - FacebookSDK search by username/pagename -

-

i'm trying access public information user based on username/pagename.

i'm doing this:

$uname = 'csga5000';  $session = new facebook\facebook([     'app_id' => self::$facebook_app_id,     'app_secret' => self::$facebook_app_secret,     'default_graph_version' => 'v2.2' ]);  try {     // returns `facebook\facebookresponse` object     $response = $session->get('/search?q='+$uname+'&type=user'); } catch(facebook\exceptions\facebookresponseexception $e) {     print_r($e);     echo 'graph returned error: ' . $e->getmessage();     exit; } catch(facebook\exceptions\facebooksdkexception $e) {     echo 'facebook sdk returned error: ' . $e->getmessage();     exit; }

but exception thrown, here output:

graph returned error: (#803) of aliases requested not exist: v2.20

alternatively(got looking @ source code)

$response = $session->sendrequest('get','/search',['q'=>$uname,'type'=>'user']);

returns "graph returned error: access token required request resource." stole reference somewhere using app id , secret token in format:

$response = $session->sendrequest('get','/search',['q'=>$uname,'type'=>'user'], self::$facebook_app_id.'|'.self::$facebook_app_secret);

this throws: "graph returned error: user access token required request resource."

i don't understand why user access token required :/

anyone know how search user based on username in php? i've seen other examples outdated, pretty same claim worked.

edit: information want acquire follower count.

first of all, can´t search users username anymore. earlier possible using simple api call: graph.facebook.com/username

this not work anymore, , search api allows search name (first/last). not supposed use username anymore.

that being said, need authorize , use user token, error message tells you. that´s how is, , can read in docs too:

  • searches across page , place objects requires app access token.
  • all other endpoints require user access token.

source: https://developers.facebook.com/docs/graph-api/using-graph-api/v2.4#search

more information tokens:
