php facebook sdk不会在wordpress中创建用户

更新时间：2023-12-01 22:19:46

请在下面找到示例代码。我已经使用JavaScript SDK进行登录，并使用PHP SDK生成访问令牌。我希望它适合你。

Please find the sample code below. I have made the use of JavaScript SDK for the login and PHP SDK for generating access-token. I hope it will work for you.

** HTML Code:: **

    <html>

    <body>

  <p><a href="#" onClick="logInWithFacebook()">Log In with the JavaScript SDK</a></p>

  <script>
    logInWithFacebook = function() {
      FB.login(function(response) {
        if (response.authResponse) {
          alert('You are logged in &amp; cookie set!');
          location.href = "//localhost/facebook/testfb.php"
            // Now you can redirect the user or do an AJAX request to
            // a PHP script that grabs the signed request from the cookie.
        } else {
          alert('User cancelled login or did not fully authorize.');
        }
      });
      return false;
    };
    window.fbAsyncInit = function() {
      FB.init({
        appId: 'app-id',
        cookie: true, // This is important, it's not enabled by default
        version: 'v2.9'
      });
    };

    (function(d, s, id) {
      var js, fjs = d.getElementsByTagName(s)[0];
      if (d.getElementById(id)) {
        return;
      }
      js = d.createElement(s);
      js.id = id;
      js.src = "//connect.facebook.net/en_US/sdk.js";
      fjs.parentNode.insertBefore(js, fjs);
    }(document, 'script', 'facebook-jssdk'));
  </script>
</body>

</html>

** PHP代码**

** PHP Code **

<?php
require_once('Facebook/autoload.php');
# /js-login.php
$fb = new Facebook\Facebook([
'app_id' => '{app-id}',
'app_secret' => '{app-secret}',
'default_graph_version' => 'v2.9',
]);

$helper = $fb->getJavaScriptHelper();


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;
}


if (!isset($accessToken)) {
    echo 'No cookie set or no OAuth data could be obtained from cookie.';
    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);


// Validation (these will throw FacebookSDKException's when they fail)
$tokenMetadata->validateAppId('{app-id}'); // Replace {app-id} with your app id
// If you know the user ID this access token belongs to, you can validate it here
//$tokenMetadata->validateUserId('123');
$tokenMetadata->validateExpiration();

if (! $accessToken->isLongLived()) {
  // Exchanges a short-lived access token for a long-lived one
  try {
    $accessToken = $oAuth2Client->getLongLivedAccessToken($accessToken);
  } catch (Facebook\Exceptions\FacebookSDKException $e) {
    echo "<p>Error getting long-lived access token: " . $helper->getMessage() . "</p>\n\n";
    exit;
  }

  echo '<h3>Long-lived</h3>';
  var_dump($accessToken->getValue());
}

$_SESSION['fb_access_token'] = (string) $accessToken;

try {
  // Returns a `Facebook\FacebookResponse` object
  $response = $fb->get('/me?fields=id,name,email', $accessToken->getValue());
} catch(Facebook\Exceptions\FacebookResponseException $e) {
  echo 'Graph returned an error: ' . $e->getMessage();
  exit;
} catch(Facebook\Exceptions\FacebookSDKException $e) {
  echo 'Facebook SDK returned an error: ' . $e->getMessage();
  exit;
}

$user = $response->getGraphUser();

echo 'Name: ' . $user['name'];
echo 'Email: ' . $user['email'];
