Question

我正在尝试获取使用php的用户朋友的列表，但它一直抛出异常，对于开发人员docs，代码与Facebook相同 https://developers.facebook.com/docs/graph-api/reference/v3.0/user/friends

这是我的代码

$fb = new \Facebook\Facebook([
        'app_id' => APP_ID,
        'app_secret' => APP_SECRET,
        'default_graph_version' => DEFAULT_GRAPH_VERSION,
        //'access_token' => '{'.$fbToken.'}', // optional
    ]);

try {
            $response = $fb->get('/friends', $fbToken);
        } catch(FacebookExceptionsFacebookResponseException $e) {
            echo 'Graph returned an error: ' . $e->getMessage();
            exit;
        } catch(FacebookExceptionsFacebookSDKException $e) {
            echo 'Facebook SDK returned an error: ' . $e->getMessage();
            exit;
        }

        $graphNode = $response->getGraphNode();

这是错误的堆栈跟踪

[03-Jul-2018 07:29:33 UTC] PHP Fatal error:  Uncaught exception 'Facebook\Exceptions\FacebookSDKException' with message 'Unable to convert response from Graph to a GraphNode because the response looks like a GraphEdge. Try using GraphNodeFactory::makeGraphEdge() instead.' in /facebook/Facebook/GraphNodes/GraphNodeFactory.php:224

Answer 1

尝试以下方法：

$graphNode = $response->getGraphEdge();

很老，所以我没有将其标记为重复项：FB Graph API query doesn't work in PHP SDK

使用PHP获取用户Facebook朋友会引发异常
