可以创建一个应用程序来上传Facebook上的个人资料图片

Question

Someone can tell me if Facebook allows to upload photos from the application? I myself have managed to upload a photo together with status but no profile photo. I am sorry for my bad English DIR . '/'; require_once($base_path . 'facebook/autoload.php'); use Facebook\FacebookSession; use Facebook\FacebookRedirectLoginHelper;

# login-callback.php
$fb = new Facebook\Facebook([
  'app_id' => '879976278753562',

  'default_graph_version' => 'v2.3',
  ]);

$helper = $fb->getRedirectLoginHelper();
try {
  $accessToken = $helper->getAccessToken();
} 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;
} catch(Exception $e){
    echo $e->getMessage();
    exit;
}

if (!isset($accessToken)) {

      if ($helper->getError()) {
        header('HTTP/1.0 401 Unauthorized');
        echo "Error: " . $helper->getError() . "

      } else {

        header('HTTP/1.0 400 Bad Request');
        echo 'Bad request';
    }
    exit;
}

// The OAuth 2.0 client handler helps us manage access tokens
$oAuth2Client = $fb->getOAuth2Client();

// Get the access token metadata from /debug_token
$tokenMetadata = $oAuth2Client->debugToken($accessToken);

if (! $accessToken->isLongLived()) {
  // Exchanges a short-lived access token for a long-lived one
  try {
    $accessToken = $oAuth2Client->getLongLivedAccessToken($accessToken);

You can't directly set the profile picture via the Graph API:

• https://developers.facebook.com/docs/graph-api/reference/user/picture/#Creating

You can't perform this operation on this endpoint.
