javascript - 用facebook做ajax功能

Question

我正在编写一个代码，将数据从 facebook 检索到我的本地主机。我被这个问题困扰了，希望你能帮忙:

(1)我通过cURL从这个fb页面获取数据:

<?php
/* ACC INFO */
$EMAIL      = "";
$PASSWORD   = "";
function cURL($url, $header=NULL, $cookie=NULL, $p=NULL)
{
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_HEADER, $header);
    curl_setopt($ch, CURLOPT_NOBODY, $header);
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
    curl_setopt($ch, CURLOPT_COOKIE, $cookie);
    curl_setopt($ch, CURLOPT_USERAGENT, $_SERVER['HTTP_USER_AGENT']);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
    if ($p) {
        curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
        curl_setopt($ch, CURLOPT_POST, 1);
        curl_setopt($ch, CURLOPT_POSTFIELDS, $p);
    }
    $result = curl_exec($ch);
    if ($result) {
        return $result;
    } else {
        return curl_error($ch);
    }
    curl_close($ch);
}
// CREATE THE COOKIES
$cookie = null;
$a = cURL("https://login.facebook.com/login.php?login_attempt=1",true,null,"email=$EMAIL&pass=$PASSWORD");
preg_match('%Set-Cookie: ([^;]+);%',$a,$b);
$c = cURL("https://login.facebook.com/login.php?login_attempt=1",true,$b[1],"email=$EMAIL&pass=$PASSWORD");
preg_match_all('%Set-Cookie: ([^;]+);%',$c,$d);
for($i=0;$i<count($d[0]);$i++)
    $cookie.=$d[1][$i].";";
/*
CODE BODY
*/
echo cURL("https://www.facebook.com/browse/likes?id=730777097049823",null,$cookie,null);
?>

(2) 我想做的下一件事是检索更多喜欢的用户。

Facebook 在“查看更多”按钮中插入了 AJAX 代码，因此我尝试使用 xmlHTTP 从 this GET 数据关联。但此链接中没有任何内容(responsexml 和responsetext)。我被困在这里了。我现在能做什么？

希望能帮到你。谢谢。

查看 Facebook Graph API:

它完全符合您的要求:

https://developers.facebook.com/docs/graph-api/reference/v2.3/object/likes

GET https://graph.facebook.com/v2.3/730777097049823/likes?access_token={insert_your_access_token_here}

{
  "data": [
    {
      "id": "123", 
      "name": "John Doe"
    }, 
    {
      "id": "234", 
      "name": "Joe Anon"
    }, 
    {
      "id": "345", 
      "name": "Ieat Pizza"
    }
  ], 
  "paging": {
    "cursors": {
      "after": "asdfasdfadsf", 
      "before": "asdfasdfadsf"
    }
  }
}
