android - facebook 登录无法将发布或管理权限(电子邮件)传递给读取授权请求

Question

我有一个按钮点击登录 facebook，但有时这段代码不起作用。抛出异常:引起:

com.facebook.FacebookException: Cannot pass a publish or manage permission (email) to a request for read authorization

这是我的 Activity 代码:

public class FacebookLoginActivity extends Activity {

    private final static String TAG="FB";

    private static final List<String> PERMISSIONS=Arrays.asList("email", "user_likes", "user_status");

    private Session.StatusCallback statusCallback=new SessionStatusCallback();

    private GraphUser user = null;

    private Bundle bundle;

    private Intent myIntent;

    private Session session;

    private static FacebookLoginActivity instance=new FacebookLoginActivity();
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        if(bundle==null){
            bundle=new Bundle();
        }
        Log.v(TAG, "in FB onCreate method");
        myIntent = this.getIntent();
        requestWindowFeature(Window.FEATURE_NO_TITLE);
        getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
        String action = ClientUtil.getElementValue("action");

        Settings.addLoggingBehavior(LoggingBehavior.INCLUDE_ACCESS_TOKENS);
        session=openActiveSession(this, true, PERMISSIONS);
        onClickLogin();
    }



    public void onClickLogin() {
        Log.v(TAG, "click login btn");
        session = Session.getActiveSession();
        if (!session.isOpened() && !session.isClosed()) {
            OpenRequest openRequest=new Session.OpenRequest(this);
            openRequest.setPermissions(PERMISSIONS);
            openRequest.setCallback(statusCallback);
            openRequest.setDefaultAudience(SessionDefaultAudience.FRIENDS);
            openRequest.setLoginBehavior(SessionLoginBehavior.SSO_WITH_FALLBACK);
            session.openForPublish(openRequest);
        } else {
            Log.v(TAG, "open active session");
            Session.openActiveSession(this, true, statusCallback);

        super.onStop();
        Log.v(TAG, "onStop method to remove fb callback");
        Session.getActiveSession().removeCallback(statusCallback);
    }

    @Override

        super.onActivityResult(requestCode, resultCode, data);
        Log.v(TAG, "onActivityResult method to call Fb Session");
        Session.getActiveSession().onActivityResult(this, requestCode, resultCode, data);
    }

    @Override

        super.onSaveInstanceState(outState);
        Session session=Session.getActiveSession();

            return session;

除非您的应用已先获得基本权限，否则您不能调用 openForPublish。

将您的 PERMISSIONS 列表分成 PERMISSIONS_READ 和 PERMISSIONS_PUBLISH，并将“email”放入 PUBLISH 端。然后调用 openForRead，然后在 session 打开时请求 NewPublishPermissions。
