登录时Facebook PHP API抛出异常 [英] Facebook PHP API throwing exception while login

问题描述

我尝试使用Facebook Graph API登录并获取用户信息.我以前用来获取用户信息的代码之前可以运行，但是今天我尝试使用Facebook登录，但是Facebook API抛出此错误.

I tried to log in with Facebook Graph API and get user info. The code I used to get user info worked before but today I tried login with facebook but Facebook API throwing this error.

未定义偏移量:1 /home/****/vendor/facebook/php-sdk-v4/src/Facebook/Http/GraphRawResponse.php在第108行

Undefined offset: 1 /home/****/vendor/facebook/php-sdk-v4/src/Facebook/Http/GraphRawResponse.php on line 108

该行位于此函数中:

public function 
setHttpResponseCodeFromHeader($rawResponseHeader)
{
    preg_match('|HTTP/\d\.\d\s+(\d+)\s+.*|', $rawResponseHeader, $match);
    $this->httpResponseCode = (int)$match[1]; // <---- HERE
}

我的代码:

    $fb = new Facebook([
        'app_id' => Data::get('fbAppId'),
        'app_secret' => Data::get('fbAppSec'),
        'default_graph_version' => 'v2.5',
    ]);

    $helper = $fb->getRedirectLoginHelper();
    $_SESSION['FBRLH_state'] = $_GET['state'];

    try {
        $accessToken = $helper->getAccessToken();
        $_SESSION['token'] = $accessToken;
        DB::table('settings')->where('userId', Auth::user()->id)->update(['fbAppToken' => $accessToken]); // save user access token to database
        $this->saveFbPages(); // save facebook pages and token
        $this->saveFbGroups(); // save facebook groups to database

    } catch (FacebookResponseException $e) {
        // When Graph returns an error
        return '[a] Graph returned an error: ' . $e->getMessage();

    } catch (FacebookSDKException $e) {
        // When validation fails or other local issues
        return '[a] Facebook SDK returned an error: ' . $e->getMessage();

    }

推荐答案

请在第107行打开/home/xxxxxx/public_html/vendor/facebook/graph-sdk/src/Facebook/Http/GraphRawResponse.php 当前代码:

Please open /home/xxxxxx/public_html/vendor/facebook/graph-sdk/src/Facebook/Http/GraphRawResponse.php on line 107 Current code:

preg_match('|HTTP/\d.\d\s+(\d+)\s+.*|',$rawResponseHeader, $match);

您可以将代码编辑为:

preg_match('/HTTP\/\d(?:\.\d)?\s+(\d+)\s+/',$rawResponseHeader, $match);

这对我来说就像魅力.希望这也能解决您的问题.感谢您提出这个美丽的问题.
