如何检查用户是否已经授予我的PHP应用程序的一定权限？ [英] How to check if a user has granted a certain set of permissions to my PHP app?

问题描述

根据，有没有办法检查用户是否已经使用基于PHP的Facebook SDK向应用程序授予了一定的权限？
我浏览过API，但找不到任何东西。

Based on this question, is there a way to check if a user has granted a certain set of permissions to an app using PHP based Facebook SDK? I've browsed the API but couldn't find anything.

推荐答案

$permissions = $facebook->api("/me/permissions");

然后使用if来检查你需要的权限

then use the if to check which permission you need

EX：

if (array_key_exists('publish_stream', $permissions['data'][0])) {
    postToWall();
} else {
    //Does not have permission
}

如果您正在使用FQL

If you are using FQL

$perms = $facebook->api(array(
    "method" => "fql.query",
    "query" => "SELECT read_stream,offline_access,publish_stream FROM permissions WHERE uid=me()"
        ));
echo "<ul>";
foreach ($perms[0] as $k => $v) {
    echo "<li>";
    if ($v === "1") {
        echo "<strong>$k</strong> permission is granted.";
    } else {
        echo "<strong>$k</strong> permission is not granted.";
    }
    echo "</li>";
}
