As of V2 of the graph api the accepted answer no longer works using a username. So now you need the userid first, and you can no longer use a username to get this. To further complicate matters, for privacy reasons, Facebook is now changing userid's per app (see https://developers.facebook.com/docs/graph-api/reference/v2.2/user/ and https://developers.facebook.com/docs/apps/upgrading/#upgrading_v2_0_user_ids ), so you will have to have some kind of proper authentication to retrieve a userid you can use. Technically the profile pic is still public and available at /userid/picture (see docs at https://developers.facebook.com/docs/graph-api/reference/v2.0/user/picture and this example user: http://graph.facebook.com/v2.2/4/picture?redirect=0) however figuring out a user's standard userid seems impossible based just on their profile - your app would need to get them to approve interaction with the app which for my use case (just showing a profile pic next to their FB profile link) is overkill.

如果有人想出了一种方法来获得基于用户名的个人资料图片，或者，如何获得一个用户id(甚至是一个交替的)来检索个人资料图片，请分享!与此同时，旧的图形url在2015年4月之前仍然有效。

获取图片URL，而不是二进制内容:

$url = "http://graph.facebook.com/$fbId/picture?type=$size";

$headers = get_headers($url, 1);

if( isset($headers['Location']) )
    echo $headers['Location']; // string
else
    echo "ERROR";

你必须使用你的FACEBOOK ID，而不是用户名。你可以在那里获得你的facebook id:

http://findmyfbid.com/

一种方法是使用Gamlet在他的回答中发布的代码:

保存为curl.php 然后在你的文件中: 需要“curl.php”; 美元的照片= " https://graph.facebook.com/me/picture?access_token= "。美元的会话(“access_token”); $sample = new sfFacebookPhoto; $thephotoURL = $sample->getRealUrl($photo); echo $ thephotoURL;

我想我应该张贴这个，因为我花了一些时间来弄清楚细节……即使个人资料照片是公开的，你仍然需要有一个访问令牌在那里，当你卷曲它。

简单的一行代码，保存完整尺寸的档案图像在您的服务器上。

<?php

copy("https://graph.facebook.com/FACEBOOKID/picture?width=9999&height=9999", "picture.jpg");

?>

只有在php.ini中启用了openssl，这才有效。

博客文章“抓取Facebook图形对象的图片”可能会提供另一种解决方案。使用教程中的代码以及Facebook的Graph API及其PHP SDK库。
