How to get username from Facebook ID
提问by Andrew
On the Internet there are a few topics about this problem, but I have not found any complex solution. Therefore, I would like to ask you for help.
在互联网上有一些关于这个问题的主题，但我没有找到任何复杂的解决方案。因此，我想请你帮忙。
I need to change facebook id to username.
我需要将 facebook id 更改为用户名。
When you type web site like this:
当您像这样输入网站时：
http://facebook.com/profile.php?id=4(num 4 is FB id), it will give you http://www.facebook.com/zuck, which is Mark Zuckerberg's profile.
http://facebook.com/profile.php?id=4（num 4 是FB id），它会给你http://www.facebook.com/zuck，这是马克扎克伯格的个人资料。
On this principle I need to find out who a id is.
根据这个原则，我需要找出一个 id 是谁。
I have typed id 4a got it is zuck.
我输入了 id4得到它是zuck。
But I need it for more ids, so it would take a lot of time do it manually. Please help me, how I can do it.
但是我需要它来获得更多的 id，所以手动完成需要很多时间。请帮助我，我该怎么做。

If you already have an ID of that particular user, then just add it on this url:
如果您已经拥有该特定用户的 ID，则只需将其添加到此 url 上：
https://graph.facebook.com/<USER_ID>
Simple example:
简单的例子：
function get_basic_info($id) {
$url = 'https://graph.facebook.com/' . $id;
$info = json_decode(file_get_contents($url), true);
return $info;
}
$id = 4;
$user = get_basic_info($id);
echo '<pre>';
print_r($user);
This should basically yield:
这应该基本上产生：
Array
(
[id] => 4
[first_name] => Mark
[gender] => male
[last_name] => Zuckerberg
[link] => https://www.facebook.com/zuck
[locale] => en_US
[name] => Mark Zuckerberg
[username] => zuck
)
Then you could just call it like a normal array:
然后你可以像普通数组一样调用它：
echo $user['username'];
Sidenote: Why not use the PHP SDK instead.
旁注：为什么不改用 PHP SDK。

As the username is NO more available from Graph API endpoint /user-idas discussed here, I propose another workaround here (but with Python code)
由于用户名不再可从 Graph API 端点获得/user-id，如此处讨论，我在这里提出另一种解决方法（但使用 Python 代码）
In brief, we open the page at fb.com/USER_IDand scrape the username from it
简而言之，我们在fb.com/USER_ID打开页面并从中抓取用户名
#get html of a page via pure python ref. https://stackoverflow.com/a/23565355/248616
import requests
r = requests.get('http://fb.com/%s' % FB_USER_ID) #open profile page of the facebook user
r.raise_for_status()
html = r.content
#search string with regex ref. https://stackoverflow.com/a/4667014/248616
import re
# m = re.search('meta http-equiv="refresh" content="0; URL=/([^?]+)\?', html)
m = re.search('a class="profileLink" href="([^"]+)"', html)
href = m.group(1) #will be https://www.facebook.com/$FB_USER_NAME on 201705.24
username = href.split('/')[-1]
print(href)
print(username)

As of October 2019, The only way it is possible is to request for user_links in request and permissions
截至 2019 年 10 月，唯一可能的方法是在请求和权限中请求 user_links
And then pass it in a scope, something like this
然后在一个范围内传递它，像这样
scope: ['user_link']
