"The domain of this URL isn't included in the app's domains" 什么时候

Question

我正在尝试从 PHP 脚本 post 到 Facebook 墙。我创建了一个 FB 应用程序，安装了 Graph PHP API，并实现了一些测试脚本如下：

fbinit.php:

<?php

session_start();

require_once('src/Facebook/autoload.php');

$fb = new Facebook\Facebook([
'app_id' => 'REDACTED',
'app_secret' => 'REDACTED',
'default_graph_version' => 'v2.9',
]);

?>

fbpost.php:

<?php

include('fbinit.php');

$helper = $fb->getRedirectLoginHelper();

$permissions = ['manage_pages','publish_pages']; //'publish_actions'
$loginUrl = $helper->getLoginUrl('https://www.REDACTED.net/fb-callback.php', $permissions);

echo '<a href="' . htmlspecialchars($loginUrl) . '">Log in with Facebook!</a>';

?>

fb-callback.php:

<?php

include('fbinit.php');

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

try {

  $accessToken = $helper->getAccessToken();

} 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;

}

if (! isset($accessToken)) {
  echo 'No OAuth data could be obtained from the signed request. User has not authorized your app yet.';
  exit;
}

try {

  $response = $fb->get('me/accounts', $accessToken->getValue());
  $response = $response->getDecodedBody();

} 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;

}

echo "<pre>";
print_r($response);
echo "</pre>";

?>

第一次打开fbpost.php，按预期要求登录Facebook，它在页面上代表我请求post的权限，这很好。但随后我被重定向到回调页面并出现以下错误：

Graph returned an error: Can't load URL: The domain of this URL isn't included in the app's domains. To be able to load this URL, add all domains and sub-domains of your app to the App Domains field in your app settings.

我已经添加了我能想到的应用 URL 和回调 URL 的所有组合，但没有任何效果。有关应用程序设置的屏幕截图，请参见下文。 App ID和secret绝对正确

redirect_uri 参数的值需要与您的登录对话框调用以及随后的 API 尝试将代码交换为令牌的调用完全相同。

当您生成登录 URL 并处理分布在不同脚本上的响应（即，通过不同的 URL 调用）时，很容易导致这样的问题。如果留给自己的设备，SDK 会尝试根据当前脚本 URL 计算出值。

在这种情况下，在您的 getAccessToken 方法调用中也明确指定回调 URL。
