使用facebook开发者API访问用户的好友信息 - Using Facebooks Developers API to access user's friend information

我目前正在制作一个网站，允许用户通过Facebook登录，并从中获得他们所有的信息，以在我的网站上使用。

e。如果他们是单身，或者他们对女人、男人或两者都感兴趣。

我一直在寻找周围的Facebook开发人员那边的网站，有一些样本代码在那里获得关于他们喜欢什么电影的信息，所以我只是想知道是否有可能改变和适应这是什么我需要的。

以下是我从本页找到的一些代码，并给出了解释:

perms="user_likes, friends_likes"></fb:login-button>
FB.api('/me/friends', function(response) { });
FB.api(‘/USER_ID/movies’, function(response) { });

FB.api('/'+movieListSorted[i].id, function(response) {
  var newDiv = document.createElement("DIV");
  newDiv.innerHTML = "<img src='"+response.picture+"'></img><br/>";
  if( response.link) {
    newDiv.innerHTML+="<a href='"+response.link+"'>"+response.link
    +"</a><br/>";
    newDiv.innerHTML+='<iframe src="http://www.facebook.com'

你检查过图形API了吗:

Facebook Graph API

你还必须确保你有适当的权限:

Facebook API权限

我建议使用PHP SDK来获取这些信息，特别是如果您是初学者的话。你可以使用他们的函数。

你可以在下面的URL找到它的源代码(包括一些文档):https://developers.facebook.com/docs/reference/php/

首先，为了从Graph API获得任何东西，您需要为您的应用程序获得用户的身份验证，这在这里有记录:

https://developers.facebook.com/docs/authentication/

然后，您可以使用API调用获得有关当前用户所需的信息。在这里记录:

http://developers.facebook.com/docs/reference/php/facebook-api/

需要注意的代码如下，我编辑了这段代码，以提供当前登录用户的' interestd_in '字段，记录在这里:

 try {
        $user_profile = $facebook->api('/me?fields=interested_in','GET');
        echo "Interested in: " . $user_profile['interested_in'];
      } catch(FacebookApiException $e) {
        // Failed API call
        error_log($e->getType());
        error_log($e->getMessage());
      }
