Javascript JS FQL评论“U信息不断返回：”；“服务暂时不可用”；

我使用JavaScript运行一个非常基本的FQL查询，并不断返回一个错误对象

{error\u code:“2”，error\u msg:“服务暂时不可用”，request\u args:Array[8]}

我的目标是阅读最近通过Facebook发布到我的网站（所有网站，不限于特定帖子）的评论的

comment_info.XID

这是我的代码，主要基于StackOverflow上发布的一些示例：

<div id="fb-root"></div>
<div id="fbcomments"></div>
<script type="text/javascript">

window.fbAsyncInit = function() {
    var fb_app_id = '*';

    FB.init({
        appId    : fb_app_id,
        session : null, // don't refetch the session when PHP already has it
        status  : true, // check login status
        cookie  : true, // enable cookies to allow the server to access the session
        xfbml    : true // parse XFBML
    });

    FB.getLoginStatus(function (response) {

        if (response.status === 'connected') {
            if (response.authResponse) {

                var fb_access_token = response.authResponse.accessToken; // I even tried hard-coding the value from: https://graph.facebook.com/oauth/access_token?type=client_cred

                FB.api(
                    {
                        method: 'fql.query',
                        query: 'SELECT xid,count FROM comments_info WHERE app_id="'+fb_app_id+'"',
                        access_token : fb_access_token
                    },
                    function(newresponse) {
                        $.each(newresponse, function(i, e) {
                             $("#fbcomments").append(""+e.text+""); // we get here, but e.text is undefined (see my error on top)
                        });         

                    }
                ); //FB.api
                    } else { //response.authResponse
                        console.log('no response.authResponse');// do something...maybe show a login prompt
                    }
            } else if (response.status === 'not_authorized') {
                console.log(' not_authorized')
            } else {
                console.log('not_logged_in')
            }
    });
};

</script>
 <script type="text/javascript"> (function(d){ var js, id = 'facebook-jssdk'; if (d.getElementById(id)) {return;} js = d.createElement('script'); js.id = id; js.async = true;js.src = "//connect.facebook.net/he_IL/all.js#appId=*&amp;xfbml=1";d.getElementsByTagName('head')[0].appendChild(js); }(document)); </script>

似乎什么都不管用。

有什么问题吗？

读取该表需要一个应用访问令牌，不应该在公共客户端代码中公开。如果我通过PHP获取应用访问令牌，javascript会自动识别它吗？如果你仍然使用PHP，那么首先用PHP进行查询-再次，您的应用程序访问令牌不应暴露在客户端。PHP也不起作用。我也犯了同样的错误：（你可能会看到我的PHP代码在上面的原始问题中被更新了……还有其他建议吗？

// get user access_token
$token_url = "https://graph.facebook.com/oauth/access_token?client_id=$app_id&client_secret=$app_secret&grant_type=client_credentials";

// response is of the format "access_token=AAAC..."
$access_token = substr(file_get_contents($token_url), 13);

$config = array(
        'appId'  => $app_id,
        'secret' => $app_secret
);
$facebook = new Facebook($config);

$user_id = $facebook->getUser();

if ($user_id) {
    $params = array(
            'method' => 'fql.query',
            'query' => "SELECT xid,count FROM comments_info WHERE app_id=$app_id",
            'access_token' => $access_token
    );

    try {
        $result = $facebook->api($params);
        var_dump($result);
    } catch (Exception $e) {
        var_dump($e);
    }


} else {
    $login_url = $facebook->getLoginUrl();
    echo 'Please <a href="' . $login_url . '">login.</a>';
}
