我正在尝试使用 Spring Social Facebook 检索用户的朋友姓名。列出好友 = facebook.friendOperations().getFriendProfiles(); 该语句给了我一个 400 Bad Request 错误。

@Controller
@RequestMapping("/")
public class HelloController {

    private Facebook facebook;

    @Inject
    public HelloController(Facebook facebook) {
        this.facebook = facebook;
    }

    @RequestMapping(method=RequestMethod.GET)
    public String helloFacebook(Model model) {
        if (!facebook.isAuthorized()) {
            return "redirect:/connect/facebook";
        }

        model.addAttribute(facebook.userOperations().getUserProfile());
        System.out.println(facebook.userOperations().getUserProfile().getName());
        System.out.println(facebook.userOperations().getUserProfile().getEmail());
        //PagedList<FacebookProfile> fbFrnds = facebook.friendOperations().getFriendProfiles();
        List<String> friendIds = facebook.friendOperations().getFriendIds();
        System.out.println("Id size : "+friendIds.size());
        List<FacebookProfile> friends = facebook.friendOperations().getFriendProfiles();
        System.out.println("Size : "+friends.size());
        for (FacebookProfile id : friends) {
            System.out.println(id.getName());
        }
        return "hello";
    }

}

错误如下所示。

我在“配置应用中心权限”中授予了以下权限。 在此处输入图像描述

知道为什么会这样吗？提前致谢。

不幸的是，Facebook 在其 Graph API 的 v2.0 中删除了“用户名”属性。因此，Spring Social Facebook 将无法尝试获取该属性。（如果这让你感到沮丧，那么想象一下当我发现他们在删除 Spring Social Facebook 版本后仅几天就将其删除时我的沮丧。）

如果您将 Spring Social Facebook 依赖项更改为 2.0.0.M1（并确保您在构建中注册了 Spring 的里程碑存储库http://repo.spring.io/milestone），那么它应该适合您。事实上，如果您试用此版本并向https://jira.spring.io/browse/SOCIALFB报告错误或改进想法，我将非常感激。

但也请注意，Facebook 的 Graph API 现在限制了应用程序可以获取哪些朋友。具体来说，如果这些朋友也是您的应用程序的用户，Graph API 只会返回用户朋友的列表。我不确定这是否能满足您的需求，但这完全是由于 Facebook 端的变化……在 Spring Social 中我无能为力。
