Question

这是我使用脸谱图API在Facebook群组中发帖的代码。但是它会返回错误。

方法1

...
Gson gson = new GsonBuilder.create();
Hashtable<Action, String> table = new Hashtable<>();
table.put(Action.CREATE, "");
gson.toJson(table) // => { "CREATE" : "" } instead of { "create" : "" }
...

ERROR

致命错误：调用未定义的方法 Facebook的\ FacebookRequest ::执行（）

方法2

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();

错误

        echo "Mail sent <br/>";
    } else {
        echo "Mail not sent. Something wrong <br/>";
    }

}

调用未定义的方法Facebook \ FacebookRequest :: execute（）
