調用未定義的方法Facebook \\ FacebookRequest :: execute（）

Question

這是我使用facebook圖譜API在facebook組中發布帖​​子的代碼。但它返回錯誤。

方法1

include 'vendor/autoload.php';
use Facebook\FacebookApp;
use Facebook\Facebook;
use Facebook\FacebookRequest;

$app_id         = 'xxxxxxxxxxxxxxx';
$psswd          = 'xxxxxxxxxxxxxxx';

$group_id       = 'xxxxxxxxxxxxxxx';

$app = new FacebookApp($app_id, $psswd);
$request = new FacebookRequest(
  $app,
  'POST',
  '/'.$group_id.'/feed',
  array (
    'message' => 'This is a test message',
  )
);
$response = $request->execute();
$graphObject = $response->getGraphObject();

ini_set('display_errors', 1);
include 'vendor/autoload.php';
use Facebook\FacebookApp;
use Facebook\Facebook;
use Facebook\FacebookRequest;

$app_id         = 'xxxxxxxxxxxx';

  'app_secret' => $psswd,
  'default_graph_version' => 'v2.4',
  ]);
$request = $fb->request('POST', '/'.$group_id.'/feed',array('message'=>'This is a test message'));

// Send the request to Graph
try {
  $response = $fb->getClient()->sendRequest($request);
} catch(Facebook\Exceptions\FacebookResponseException $e) {
  // When Graph returns an error
  echo 'Graph returned an error: ' . $e->getMessage();
  exit;
} catch(Facebook\Exceptions\FacebookSDKException $e) {
  // When validation fails or other local issues
  echo 'Facebook SDK returned an error: ' . $e->getMessage();
  exit;
}

$graphNode = $response->getGraphNode();

print_r($graphNode);
