Facebook API：获取喜欢页面的人的粉丝/ [英] Facebook API: Get fans of / people who like a page

问题描述

我想得到一个喜欢某个页面或者粉丝的用户列表。

I'd like to get a list of users who like a certain page or a fan of it.

FB API文档指出，您只能使用社交图表获取某个网页的粉丝的数量，但不能使用粉丝列表。

The FB API documentation states that you can only get the count of the fans of a certain page using the social graph, but not a list of the fans.

这里的讨论检索Facebook粉丝名称表明可以使用FQL查询，如 SELECT user_id FROM like WHERE object_id =您的页面ID以获取喜欢该页面的人数，但是对于同一页面，它给出了一个空的响应{}

A discussion here Retrieve Facebook Fan Names suggests that one could use an FQL query like SELECT user_id FROM like WHERE object_id="YOUR PAGE ID" to get the number of people who liked the page, but for the same page, it gives an empty response "{}".

所以我想知道是否有人有想法，如果这可以完成。

So I was wondering if anyone has an idea if this can be done.

推荐答案

有一种方式来获取一些粉丝列表的一部分，其中没有标记的个人资料ID。

There is a "way" to get some part of fan list with their profile ids of some fanpage without token.

1. 获取有公开图形数据的粉丝专页的编号： http://graph.facebook.com/cocacola - 可口可乐有40796308305。 更新2016.04.30 ：Facebook now req使用访问令牌以通过图形获取page_id，以便您可以解析f​​anpage HTML语法来获取此ID，而无需任何 https://www.facebook.com/ {PAGENAME} 的授权在下面的例子中，基于粉丝页面上的og标签。


2. 获取可口可乐的like pluginiframe直接显示一些修改的参数： http://www.facebook.com/plugins/fan.php?connections=100&id=40796308305


3. 现在查看页面来源，有很多粉丝拥有其个人资料的链接，您可以在其中找到他们的个人资料ID或昵称，如： http://www.facebook.com/michal.semeniuk 。


4. 如果你只对配置文件ids有兴趣再次使用图表api - 它会直接给你个人资料ID： http：//图.facebo ok.com/michal.semeniuk 更新2016.04.30：Facebook现在需要访问令牌才能获取此类信息。您可以解析配置文件HTML语法，就像第一步元标记是您最好的朋友：
   < meta property =al：android：urlcontent =fb：// profile / {PROFILE_ID}/>

1. Get id of a fanpage with public graph data: http://graph.facebook.com/cocacola - Coca-Cola has 40796308305. UPDATE 2016.04.30: Facebook now requires access token to get page_id through graph so you can parse fanpage HTML syntax to get this id without any authorization from https://www.facebook.com/{PAGENAME} as in example below based on og tags present on the fanpage.
2. Get Coca-Cola's "like plugin" iframe display directly with some modified params: http://www.facebook.com/plugins/fan.php?connections=100&id=40796308305
3. Now check the page sources, there are a lot of fans with links to their profiles, where you can find their profile ids or nicknames like: http://www.facebook.com/michal.semeniuk .
4. If you are interested only in profile ids use the graph api again - it will give you profile id directly: http://graph.facebook.com/michal.semeniuk UPDATE 2016.04.30: Facebook now requires access token to get such info. You can parse profile HTML syntax, just like in the first step meta tag is your best friend: <meta property="al:android:url" content="fb://profile/{PROFILE_ID}" />

现在是最好的部分：尝试刷新）点2中的链接..有一个新的可口可乐的另一个粉丝的全套。只有单一的，你可以得到一些很好的，几乎完整的粉丝列表。

And now is the best part: try to refresh (F5) the link in point 2.. There is a new full set of another fans of Coca-Cola. Take only uniques and you will be able to get some nice, almost full list of fans.

为什么不使用我的PHP脚本来获取一些粉丝？ ：）

Why don't you use my ready PHP script to fetch some fans? :)

更新2016.04.30 ：更新了在Facebook开始需要访问令牌以从图形API获取公开数据后使用新方法的示例脚本

UPDATE 2016.04.30: Updated example script to use new methods after Facebook started to require access token to get public data from graph api.

function fetch_fb_fans($fanpage_name, $no_of_retries = 10, $pause = 500000 /* 500ms */){
    $ret = array();
    // prepare real like user agent and accept headers
    $context = stream_context_create(array('http' => array('header' => 'User-Agent: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Ubuntu Chromium/49.0.2623.108 Chrome/49.0.2623.108 Safari/537.36\r\nAccept: text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8\r\nAccept-encoding: gzip, deflate, sdch\r\nAccept-language: en-US,en;q=0.8,pl;q=0.6\r\n')));
    // get page id from facebook html og tags for mobile apps
    $fanpage_html = file_get_contents('https://www.facebook.com/' . $fanpage_name, false, $context);
    if(!preg_match('{fb://page/(\d+)}', $fanpage_html, $id_matches)){
        // invalid fanpage name
        return $ret;
    }
    $url = 'http://www.facebook.com/plugins/fan.php?connections=100&id=' . $id_matches[1];
    for($a = 0; $a < $no_of_retries; $a++){
        $like_html = file_get_contents($url, false, $context);
        preg_match_all('{href="https?://www\.facebook\.com/([a-zA-Z0-9\._-]+)" data-jsid="anchor" target="_blank"}', $like_html, $matches);
        if(empty($matches[1])){
            // failed to fetch any fans - convert returning array, cause it might be not empty
            return array_keys($ret);
        }else{
            // merge profiles as array keys so they will stay unique
            $ret = array_merge($ret, array_flip($matches[1]));
        }
        // don't get banned as flooder
        usleep($pause);
    }
    return array_keys($ret);
}

print_r(fetch_fb_fans('TigerPolska', 2, 400000));
