facebook api php 新闻提要 获取大图

Question

我在我的会员网站中添加新闻提要图片，需要帮助从新闻提要中获取大图片。

这是我获取新闻提要图片的代码

$json_object = @file_get_contents('https://graph.facebook.com/me/home?access_token=' . $fb_access_token); $news_feeds = json_decode($json_object, true);

foreach($news_feeds['data'] as $news_feed) 
{
echo '<img src="' . $news_feed['picture'] . '" />' . '<br />';
}

这给了我很好的新闻提要图片，但大小不同。

任何帮助都会很好！

我找了很久还是找不到答案？

这是我试图从中获取大图的 facebook 新闻提要数组的示例。

[id] => 1423830694520861_1508536172716979
                [from] => Array
                    (
                        [category] => Public figure
                        [name] => Dan Bilzerian
                        [id] => 1423830694520861
                    )

                [to] => Array
                    (
                        [data] => Array
                            (
                                [0] => Array
                                    (

                                        [id] => 244183679061369
                                    )

                            )

                    )

                [message] => Happy 21st to Jen Selter and her #NeverEndingAss
                [message_tags] => Array
                    (
                        [14] => Array
                            (
                                [0] => Array
                                    (
                                        [id] => 244183679061369
                                        [name] => Jen Selter
                                        [type] => page
                                        [offset] => 14
                                        [length] => 10
                                    )

                            )

                    )

我相信我必须将 _n.jpg 更改为 _b.jpg 或 p130x130 到 b740x740 但该功能不起作用？？

我尝试在 foreach 循环之前/之后运行此函数。但是还是不行？

$news_feed ['picture'] = str_replace("_n.jpg", "_b.jpg", $news_feed['picture']);

还有这个

$news_feed ['picture'] = str_replace("p130x130", "b740x740", $news_feed['picture']);

有人可以帮忙吗，:(谢谢

试试 object_id ....它对我有用 :)

echo '<img src="https://graph.facebook.com/' . $news_feed['object_id'] . '/picture?type=normal">' . '<br />';
