Facebook access_token 2 小时后过期

Question

PHP 脚本成功从我的 Facebook 页面获取提要：

    $access_token = 'XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX';

    $url = 'https://graph.facebook.com/v2.2/711493158867950/feed?access_token='.$access_token;
    $curl = curl_init();

    $header[0] = "Accept: text/xml,application/xml,application/xhtml+xml,";
    $header[0] .= "text/html;q=0.9,text/plain;q=0.8,image/png,*/*;q=0.5";
    $header[] = "Cache-Control: max-age=0";
    $header[] = "Connection: keep-alive";
    $header[] = "Keep-Alive: 300";
    $header[] = "Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7";
    $header[] = "Accept-Language: en-us,en;q=0.5";
    $header[] = "Pragma: "; // browsers keep this blank.

    curl_setopt($curl, CURLOPT_URL, $url);
    curl_setopt($curl, CURLOPT_USERAGENT, 'Mozilla');
    curl_setopt($curl, CURLOPT_HTTPHEADER, $header);
    curl_setopt($curl, CURLOPT_REFERER, '');
    curl_setopt($curl, CURLOPT_ENCODING, 'gzip,deflate');
    curl_setopt($curl, CURLOPT_AUTOREFERER, true);
    curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($curl, CURLOPT_TIMEOUT, 10);

    $json = curl_exec($curl);

但两个小时后 access_token 到期，我收到以下错误：http://prntscr.com/60jyqt。如何将下面的php代码重写为"renew"access_token键？

Answer 1

您可以先看看文档：

Answer 2

这对我有用（Facebook SDK v3.1）：

1) 创建一个"system user"

2) 授予他访问我需要的属性的权限（在我的例子中是应用程序）

3) 为该应用程序和系统用户生成一个新令牌

我使用的指令可以找到here
