如何从Facebook Graph Api访问帖子数据,如[message]和[created_time]?
这是JSON的print_r,我从Facebook Graph Api获得
Array
(
[posts] => Array
(
[data] => Array
(
[0] => Array
(
[message] => random message.
[created_time] => 2016-11-12T07:26:23+0000
[id] => id786456786
)
[1] => Array
(
[message] => random message.
[created_time] => 2016-11-11T04:30:02+0000
[id] => id123456768
)
)
[paging] => Array
(
[previous] => https://graph.facebook.com/v2.8/pageid/posts?limit=2&since=1478935583&access_token=MY ACCESS TOKEN ....
)
)
[id] => id
)
我的PHP代码:
$data = file_get_contents("https://graph.facebook.com/v2.8facebookpageid?fields=posts.limit(2)&access_token=MY_ACCESS_TOKEN");
$decoded = json_decode($data,true);
print_r($decoded);

您只需按照数组的键即可:
$decoded = json_decode($data, true);
// Retrieve the first message.
$message = $decoded['posts']['data'][0]['message']
// Retrieve the second message.
$message = $decoded['posts']['data'][1]['message']
更好的是,您可以循环浏览$decoded['posts']['data']
,如此:
$decoded = json_decode($data, true);
foreach ($decoded['posts']['data'] as $item) {
echo "Message: {$item['message']}\n";
echo "Created Time: {$item['created_time']}\n";
}

希望这有帮助!
