call Api facebook with php

本文关键字：php with facebook Api call | 更新日期: 2023-09-27

你好

我的代码有点问题：

如果我使用，它会起作用

FB.api('https://graph.facebook.com/','post',  {
    id: 'http://example.fr/',
    scrape: true,
    access_token:'xxxxx|xxxxxx'
}, function(response) {
    console.log('rescrape!',response);
});

对于安全令牌，我想使用serveur端，如果我使用以下代码（使用ajax发送url）：

    class FacebookDebugger {
        public function reload($url)
{
    $token = 'xxxxxxxxxxxxxxx|xxxxxxxxxxx';
    $graph = 'https://graph.facebook.com/';
    $post = 'id='.urlencode($url).'&scrape=true&access_token='.$token;
    return $this->send_post($graph, $post);
}
    private function send_post($url, $post)
    {
        $r = curl_init();
        curl_setopt($r, CURLOPT_URL, $url);
        curl_setopt($r, CURLOPT_POST, 1);
        curl_setopt($r, CURLOPT_POSTFIELDS, $post);
        curl_setopt($r, CURLOPT_RETURNTRANSFER, 1);
        curl_setopt($r, CURLOPT_CONNECTTIMEOUT, 5);
        $data = curl_exec($r);
        curl_close($r);
        return $data;
    }
}

    $fb = new FacebookDebugger();
    $fb = $fb->reload($url)

它不起作用。响应ajax

   $fb = new FacebookDebugger();
        $fbrepons = $fb->reload($url)
        echo var_dump($fbrepons);

我有"布尔false"。

一个主意？

感谢您的帮助

在这里找到好的代码

有没有API可以迫使Facebook再次抓取页面？

//Provide a URL in $url to empty the OG cache
function clear_open_graph_cache($url) {
  $vars = array('id' => $url, 'scrape' => 'true');
  $body = http_build_query($vars);
  $fp = fsockopen('ssl://graph.facebook.com', 443);
  fwrite($fp, "POST / HTTP/1.1'r'n");
  fwrite($fp, "Host: graph.facebook.com'r'n");
  fwrite($fp, "Content-Type: application/x-www-form-urlencoded'r'n");
  fwrite($fp, "Content-Length: ".strlen($body)."'r'n");
  fwrite($fp, "Connection: close'r'n");
  fwrite($fp, "'r'n");
  fwrite($fp, $body);
  fclose($fp);
}

有一个如何生成Oauth令牌的指南。然后，您必须在curl请求中附加附加头。

private function send_post($url, $post) {
    $r = curl_init();
    curl_setopt($r, CURLOPT_URL, $url);
    curl_setopt($r, CURLOPT_POST, 1);
    curl_setopt($r, CURLOPT_POSTFIELDS, $post);
    curl_setopt($r, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($r, CURLOPT_CONNECTTIMEOUT, 5);
    $auth_header = 'Oauth ' . {YOUR OAUTH TOKEN};
    curl_setopt($r, CURLOPT_HTTPHEADER, array($auth_header));
    $data = curl_exec($r);
    curl_close($r);
    return $data;
}
