How can I get facebook cover url from Facebook graph API

本文关键字：facebook 获得封面 url API 图形 | 更新日期: 2023-09-27

我使用:http://graph.facebook.com/{user_id or page_id}?fields=cover

浏览器返回:

{
  "cover": {
    "id": "XXX", 
    "source": "https://fbcdn-sphotos-a-a.akamaihd.net/hphotos-ak-ash4/311205_989690200741_1231438675_n.jpg", 
    "offset_y": 66
  }, 
  "id": "XXXXXX"
}

如何将字段source和offset_y转换为PHP变量?

我的函数:

function cover_img($fb_user_name) {
    $cover_data = 'https://graph.facebook.com/'.$fb_user_name.'?fields=cover';
    $JSONString = file_get_contents($cover_data);
    $parsedJSON = json_decode($JSONString);
    echo $source = $parsedJSON->cover->source;
    echo $offset_y = $parsedJSON->cover->offset_y;
}

要在PHP中解析JSON，您需要使用json_decode(returned_facebook_json)，然后像访问对象一样访问数据，例如

$JSONString=file_get_contents('http://graph.facebook.com/{user_id or page_id}?fields=cover');
$parsedJSON = json_decode($JSONString);
echo $source = $parsedJSON->cover->source;
echo $offset_y = $parsedJSON->cover->offset_y;
