如何从facebook API获取组ID

我有代码，我得到了数组（[name] =＆gt; xxxx [first_name] =＆gt; xxxx [last_name] =＆gt; xxxx [email] =＆gt; xxxx [id] =＆gt; xxxxx）

现在我想要群组ID，如何可能请协助

Answer 1

如何获取您管理的所有群组的列表在文档中得到了很好的解释，包括示例代码：https://developers.facebook.com/docs/graph-api/reference/user/groups/

您需要使用or授权进行授权，并调用 user_managed_groups 端点。不要使用该端点的用户ID，只需使用/me/groups - 它无论如何都指向当前用户：

/me

请注意，您只能获得自己管理的群组，而无法访问您所属的群组。取消所有群组的$groups_request = $fb->get('/me/groups'); $groups = $groups_request->getGraphNode()->asArray();权限已被删除： https://developers.facebook.com/docs/apps/changelog#v2_4（搜索＆＃34; 90天弃用＆＃34;）

Answer 2

要访问用户组，您需要使用User Groups endpoint

要阅读用户的Facebook群组，您需要通过以下方式进行另一次API调用：

$profile_request = $fb->get('/me?fields=name,first_name,last_name,email');
$profile = $profile_request->getGraphNode()->asArray();

$groups_request = $fb->get("{$profile['id']}/groups");
$groups = $groups_request->getGraphNode()->asArray();

由于您在“/ me”电话中检索了ID，因此您几乎就在那里。

您可以稍微更改一下代码：
