如何使用 Spring Social 获取 Facebook 好友列表

How to get Facebook friends list in using Spring Social

我正在尝试获取 FB 好友列表。我知道它 return 只有那些也在使用该应用程序的人。

我做了 REST 点,应该 return 好友列表。这是修改后的测试代码:

@RequestMapping(value = "/fbfriends",
    method = RequestMethod.GET,
    produces = MediaType.APPLICATION_JSON_VALUE)
@Timed
public List<User> GetFriends(Connection<?> connection) {
    log.debug("REST request to get all Friends");
    if (connection == null) {
        log.error("Cannot create social user because connection is null");
        throw new IllegalArgumentException("Connection cannot be null");
    }
    log.debug("Got connection");

    List<Permission> permissions = facebook.userOperations().getUserPermissions();
    log.debug("Permission size: " + permissions.size() + " Permission: " + permissions);
    for (Permission perm: permissions){
        log.debug(perm.getName() + " " + perm.getStatus());
    }

    List<User> friends = facebook.friendOperations().getFriendProfiles();
    log.debug("Friends size: " + friends.size() + " Friends:" + friends.toString());

    PagedList<Post> feed = facebook.feedOperations().getFeed();
    log.debug("Feed size: " + feed.size() + " Feed: " + feed.toString());

    PagedList<UserTaggableFriend> taggable = facebook.friendOperations().getTaggableFriends();
    log.debug("Taggable size: " + friends.size() + " Taggable:" + friends.toString());

    log.debug("Ho Ho Ho");

    return friends;
}

所有这些 log.debug 只为我,结果如下:

如您所见,只授予了两个权限:public_profileemail

在一些示例中,我发现可以添加权限:

我没有找到这样的东西。在我的应用程序设置中,我只在 "App Review"

下找到了这个页面

这里是user_friends"live and available for users"

  1. 我做错了什么或如何使用 Spring Social 实际使用此 "granted by default" 权限?
  2. 我如何请求像 user_posts 这样的额外权限并在 Spring 框架中使用它们?

我的问题的解决方案非常简单。如果有人遇到同样的问题,请在 Facebook 登录按钮上向 FB 请求定义应用程序的权限。

这取决于你的情况。

<fb:login-button scope="public_profile,email,user_friends" onlogin="checkLoginState();">
</fb:login-button>

对此不熟悉,只是使用了登录按钮的示例代码,未经审查,认为在应用程序设置中定义了权限。
