如何通过facebook graph api获取群组的所有帖子 [英] How to get all posts of a group via facebook graph api

问题描述

我想从 facebook 群组中获取其 ID 中的所有帖子.我试过这个:

I want to grab all the posts from the facebook group with reference to its ID. I tried this:

https://graph.facebook.com/".$group_id."/feed?time_format=U&".$authToken

它只给我某些帖子.如果可能的话，如果不是通过分页 url，我希望所有帖子都可以通过单个 url 检索.但是分页网址包含分页标记为

which only gives me certain posts. I want all the posts to be retrieved by a single url if possible if not by pagination url. But pagination url contains paging token as

https://graph.facebook.com/55259308085/feed?limit=500&access_token=ACCESS_TOKEN&until=1298025645&__paging_token=55259308085_10150259582898086

什么是分页令牌和直到 ??

What is paging token and Until ??

请指引我走向正确的道路.谢谢.

Please direct me to the right path. Thank you.

推荐答案

set_time_limit(99999999);
ini_set('memory_limit', "9999M");

function fetchUrl($url) {
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_TIMEOUT, 40);
    
    $data = curl_exec($ch);
    curl_close($ch);
    
    return $data;
}

$url_array = array();

function recurse_it($url, $c) {
    global $url_array;
    $feeds         = fetchUrl($url);
    $feed_data_obj = json_decode($feeds, true);
    if (!empty($feed_data_obj['data'])) {
        $next_url      = $feed_data_obj['paging']['next'];
        $url_array[$c] = $next_url;
        recurse_it($next_url, $c + 1);
    }
    return $url_array;
}

$url = "https://graph.facebook.com/55259308085/groups?access_token=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx";
$arr = recurse_it($url, 0);
print_r($arr);

其中 $arr 是所有可用分页链接的数组，我使用 foreach 循环遍历分页的所有内容.

Where $arr is an array of all the available pagination links for which I used a foreach to loop through all the contents of the pagination.
