Answer 1

Facebook 登录成功后使用 Spring 社交库获取头像。

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

    private Facebook facebook;
    private ConnectionRepository connectionRepository;

    public MainController(Facebook facebook, ConnectionRepository connectionRepository) {
        this.facebook = facebook;
        this.connectionRepository = connectionRepository;
    }

    @RequestMapping(value = "feed", method = RequestMethod.GET)
    public String feed(Model model) {

        if(connectionRepository.findPrimaryConnection(Facebook.class) == null) {
            return "redirect:/connect/facebook";
        }

        byte[] profilePicture = facebook.userOperations().getUserProfileImage();
        User userProfile = facebook.userOperations().getUserProfile();
        model.addAttribute("userProfile", userProfile);
        PagedList<Post> userFeed = facebook.feedOperations().getFeed();
        model.addAttribute("userFeed", userFeed);
        return "feed";
    }
}
