java - 以页面而非用户身份在 Facebook 页面上发帖

Question

我正在尝试以管理员身份发布到 Facebook 页面。该帖子始终显示为用户，而不是该帖子由页面保存。

这是代码，我在用户墙上发布了一个示例，并添加了manages_page权限并将me/feed更改为page_id

Java 文件:

public class MainFragment extends Fragment {

private static final String TAG = "MainFragment";

private UiLifecycleHelper uiHelper;
private Session.StatusCallback callback = new Session.StatusCallback() {
    @Override
    public void call(final Session session, final SessionState state,
            final Exception exception) {
        onSessionStateChange(session, state, exception);
    }
};

private Button shareButton;

private static final List<String> PERMISSIONS = Arrays.asList("publish_actions");


private static final String PENDING_PUBLISH_KEY = "pendingPublishReauthorization";

private boolean pendingPublishReauthorization = false;
TextView text;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {
    View view = inflater.inflate(R.layout.main, container, false);
    text = (TextView)view.findViewById(R.id.textView1);
    LoginButton authButton = (LoginButton) view
            .findViewById(R.id.authButton);
    authButton.setFragment(this);
    authButton.setPublishPermissions("manage_pages");
    shareButton = (Button) view.findViewById(R.id.shareButton);
    shareButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            publishStory();
        }
    });

    if (savedInstanceState != null) {
        pendingPublishReauthorization = savedInstanceState.getBoolean(
                PENDING_PUBLISH_KEY, false);
    }
    return view;
}

@Override

    super.onCreate(savedInstanceState);

    uiHelper = new UiLifecycleHelper(getActivity(), callback);
    uiHelper.onCreate(savedInstanceState);
}

@Override

    super.onResume();

    // For scenarios where the main activity is launched and user
    // session is not null, the session state change notification
    // may not be triggered. Trigger it if it's open/closed.
    Session session = Session.getActiveSession();

    outState.putBoolean(PENDING_PUBLISH_KEY, pendingPublishReauthorization);
    uiHelper.onSaveInstanceState(outState);

Answer 1

显然您没有获取页面访问 token ，而是使用用户访问 token 。请求 manage_pages 权限是正确的做法，但之后您需要调用

/me/accounts

获取各个页面的访问 token 。之后，您必须使用此访问 token 向

{page_id}/feed
