如何验证 Facebook 应用 ID

发布于 2024-11-19 13:59:38 字数 136 浏览 0 评论 0原文

我需要检查给定的 Facebook 应用程序 ID 是否有效。另外，我需要检查为此应用程序 ID 设置了哪些域和站点配置。它是通过 PHP 还是 Javascript 完成并不重要。

我查遍了所有地方，但找不到任何有关此的信息。有什么想法吗？

您可以通过访问 http://graph.facebook.com/ 并查看它是否加载您期望的内容来验证 ID。有关应用程序信息，请尝试使用 admin.getAppProperties，使用属性从此列表。

使用图形 API。简单的请求：

https://graph.facebook.com/<appid>

它应该返回一个如下所示的 JSON 对象：

{
  id: "<appid>",
  name: "<appname>",
  category: "<app category>",
  subcategory: "<app subcategory>",
  link: "<applink>",
  type: "application",
}

因此，要验证指定的 app_id 是否确实是应用程序的 id，请查找 type 属性并检查它是否为 application。如果根本没有找到 id，它只会返回 false。

例如：

<?php
$app_id = 246554168145;
$object = json_decode(file_get_contents('https://graph.facebook.com/'.$app_id));
// the object is supposed to have a type property (according to the FB docs)
// but doesn't, so checking on the link as well. If that gets fixed
// then check on isset($object->type) && $object->type == 'application'
if ($object && isset($object->link) && strstr($object->link, 'http://www.facebook.com/apps/application.php')) {
   print "The name of this app is: {$object->name}";
} else {
   throw new InvalidArgumentException('This is not the id of an application');
}
?>

Use the Graph API. Simply request:

https://graph.facebook.com/<appid>

It should return you a JSON object that looks like this:

{
  id: "<appid>",
  name: "<appname>",
  category: "<app category>",
  subcategory: "<app subcategory>",
  link: "<applink>",
  type: "application",
}

So, to validate if the specified app_id is indeed the id of an application, look for the type property and check if it says application. If the id is not found at all, it will just return false.

More info: https://developers.facebook.com/docs/reference/api/application/

For example:

<?php
$app_id = 246554168145;
$object = json_decode(file_get_contents('https://graph.facebook.com/'.$app_id));
// the object is supposed to have a type property (according to the FB docs)
// but doesn't, so checking on the link as well. If that gets fixed
// then check on isset($object->type) && $object->type == 'application'
if ($object && isset($object->link) && strstr($object->link, 'http://www.facebook.com/apps/application.php')) {
   print "The name of this app is: {$object->name}";
} else {
   throw new InvalidArgumentException('This is not the id of an application');
}
?>

使用 Graph API：

$fb = new Facebook\Facebook(/* . . . */);

// Send the request to Graph
try {
  $response = $fb->get('/me');
} 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;
}

var_dump($response);
// class Facebook\FacebookResponse . . .

Use the Graph API:

$fb = new Facebook\Facebook(/* . . . */);

// Send the request to Graph
try {
  $response = $fb->get('/me');
} 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;
}

var_dump($response);
// class Facebook\FacebookResponse . . .
