我正在使用Facebook Ads API,对此我是全新的。提取广告帐户时出现错误。错误是Invalid OAuth access token.收到此错误后,我来到Google并进行了类似的搜索 First Link Another one another one。但是没有找到任何解决方案,所以我决定来Stackoverflow ,所以这个问题不再重复

这是我如何使用Facebook Ads API的代码

public function login() {

        $helper = $this->facebook->getRedirectLoginHelper();
        $this->request->session()->write('fb_access_token', false);
        $access_token =  $this->request->session()->read('fb_access_token');

        if ($access_token) {
            echo "You are logged in!";
          } else {
            $permissions = ['email', 'ads_management', 'pages_show_list', 'publish_pages', 'manage_pages', 'ads_read'];
            $loginUrl = $helper->getLoginUrl('http://localhost/FacebookManager/Adsmanagement/authenticate', $permissions);
            echo '<a href="' . $loginUrl . '">Log in with Facebook</a>';
          }
    }

    public function authenticate() {
        if (isset($_GET['state'])) {
            $helper = $this->facebook->getRedirectLoginHelper();
            $helper->getPersistentDataHandler()->set('state', $_GET['state']);
            $accessToken = $helper->getAccessToken();
            if($accessToken) {
                echo "got the token";
                $this->request->session()->write('fb_access_token', $accessToken);
                //echo $accessToken; 
                $oAuth2Client = $this->facebook->getOAuth2Client();
                $longLivedAccessToken = $oAuth2Client->getLongLivedAccessToken($accessToken);

                $this->facebook->setDefaultAccessToken($longLivedAccessToken);


            }
        }
    }

我正在获得这样的帐户

public function getAdsAccount() {
        $accesstoken = $this->request->session()->read('fb_access_token');
        //$accesstoken = "AQwfmuNgKZCZCiZBuhAMGB8xZBty5dgNR7J9ZBO2ZCDl1SWYxnBLn9ahIn5FQTWxkJ0FPKbemeG0vUAwPsZCN2FFxOFey9BQr8CZBW07IwlZB0FK81SH8ozOil2GllR35BCyxQGhQ7JrtuCdNE6kjEOU0FZCAZDZD";
        Api::init(
            $this->app_id, // App ID
            $this->appsecret,
            $accesstoken // Your user access token
          );
        //*****************
        $account = new AdAccount('****************');
        $contracts = $account->read();

        echo "<pre>"; print_r($contracts->getData());
    }

因此,我正在使用开发人员帐户,尝试通过Facebook的测试用户从APP仪表板->角色->测试用户中获取此帐户。我正在设置适当的权限等。不知道我在哪里错了。

更新 现在的问题是,是否可以从Graph Explorar创建访问令牌,但是可以,如果我使用SDK创建,则会给我错误“无效的Tokan Tokan”

请帮助我。提前致谢。

您好@manoj Kumar,请使用下面的URL(具有管理员登录名)进行检查,以调试AccessToken

https://developers.facebook.com/tools/explorer/

请检查以下来自Facebook PHP SDK的代码,以获取具有权限ads_management的有效访问令牌。

require_once __DIR__ . '/vendor/autoload.php';

use Facebook\Facebook;
use Facebook\Exceptions\FacebookResponseException;
use Facebook\Exceptions\FacebookSDKException;

// Init PHP Sessions
session_start();

$fb = new Facebook([
  'app_id' => '{your-app-id}',
  'app_secret' => '{your-app-secret}',
]);

$helper = $fb->getRedirectLoginHelper();

if (!isset($_SESSION['facebook_access_token'])) {
  $_SESSION['facebook_access_token'] = null;
}

if (!$_SESSION['facebook_access_token']) {
  $helper = $fb->getRedirectLoginHelper();
  try {
    $_SESSION['facebook_access_token'] = (string) $helper->getAccessToken();
  } catch(FacebookResponseException $e) {
    // When Graph returns an error
    echo 'Graph returned an error: ' . $e->getMessage();
    exit;
  } catch(FacebookSDKException $e) {
    // When validation fails or other local issues
    echo 'Facebook SDK returned an error: ' . $e->getMessage();
    exit;
  }
}

if ($_SESSION['facebook_access_token']) {
  echo "You are logged in!";
} else {
  $permissions = ['ads_management'];
  $loginUrl = $helper->getLoginUrl('http://localhost:8888/marketing-api/', $permissions);
  echo '<a href="' . $loginUrl . '">Log in with Facebook</a>';
}

之后,您必须获取AdAccount,因此请使用以下代码

use FacebookAds\Object\AdUser;

// Add after Api::init()
$me = new AdUser('me');
$my_adaccount = $me->getAdAccounts()->current();

这实际上是我的错误。 Facebook API向我们返回一个保护对象。如果您打印变量,它将显示为字符串。

<?php
echo $longLivedAccessToken;
var_dump($longLivedAccessToken);
?>

输出类似于 enter image description here

我尝试了$longLivedAccessToken->getValue();

$oAuth2Client = $this->facebook->getOAuth2Client();
$longLivedAccessToken = $oAuth2Client->getLongLivedAccessToken($accessToken);
$accesstoken = $longLivedAccessToken->getValue();
$this->request->session()->write('fb_access_token', $accesstoken);
$this->facebook->setDefaultAccessToken($longLivedAccessToken);
