android facebook sdk - Session:尝试重新授权具有待处理请求的会话

Question

在过去的几天里,我一直在敲打facebook-sdk-for-android-wall,需要帮助.我找不到什么是错的,我应该做什么,或者如何检查一些我缺少的状态.

我的Android应用程序正在录制曲目,对于曲目,用户必须选择将曲目摘要发布到他/她的Facebook时间线.我已经让它作为一个快乐的流程工作,但在测试不同的场景,如没有互联网连接等我现在卡在一个状态,我只得到"会话:尝试重新授权具有待处理请求的会话" - 尝试重新授权权限时出现异常(即使恢复了互联网连接).我正在使用facebook SDK for android和SSO.

package com.test;

import java.io.Fil...

public class FaceBookUtil {

public interface FacebookPostCallback {
    void onComplete(String postId);
    void onError(Exception e);
    void onError();
}

private static final List<String> PERMISSIONS = Arrays.asList("publish_actions", "publish_stream");
private static final int REAUTH_ACTIVITY_CODE = 100;

public static void postToFaceBook(final Track track, final Activity activity, final FacebookPostCallback postCallback) {

    try {
        Session session = initFacebookSession(activity.getApplicationContext());
        Session.setActiveSession(session);

        StatusCallback statusCallback = new StatusCallback() {
            @Override
            public void call(Session session, SessionState state, Exception exception) {

                try {
                    // Check for publish permissions    
                    List<String> permissions = session.getPermissions();
                    if (!isSubsetOf(PERMISSIONS, permissions)) {
                        Session.ReauthorizeRequest reauthRequest = new Session
                                .ReauthorizeRequest(activity, PERMISSIONS)
                                .setRequestCode(REAUTH_ACTIVITY_CODE);
                        session.reauthorizeForPublish(reauthRequest);    //Here's where it breaks and the exceptions is thrown.
                        return;
                    }

                    Bundle postParams = new Bundle();
                    postParams.putString("name", "Facebook post test"); 
                    postParams.putString("caption", "Just a test"); 
                    postParams.putString("description", "A description");
                    postParams.putString("link", "http://www.google.com/");

                    Request.Callback reqCallback = new Request.Callback() {
                        public void onCompleted(Response response) {
                            String postId = null;

                            try {
                                FacebookException error = response.getError();
                                if (error != null)
                                    throw error;

                                JSONObject graphResponse = response.getGraphObject().getInnerJSONObject();

                                postId = graphResponse.getString("id");
                                if (postId != null)
                                    postCallback.onComplete(postId);

                            } catch (Exception e) {
                                postCallback.onError();
                            }

                            if (postId == null)
                                postCallback.onError();
                        }
                    };

                    Request postRequest = new Request(session, "me/feed", postParams, HttpMethod.POST, reqCallback);
                    RequestAsyncTask task = new RequestAsyncTask(postRequest);
                    task.execute();

                } catch (Exception e) {
                    postCallback.onError(e);
                }
            }
        };

        if (session.getState().equals(SessionState.CREATED_TOKEN_LOADED))
            session.openForRead(new Session.OpenRequest(activity).setCallback(statusCallback));

        else if (!session.isOpened() && !session.isClosed()) {
            OpenRequest req = new Session.OpenRequest(activity);
            req.setCallback(statusCallback);
            session.openForRead(req);

        } else {
            Session.openActiveSession(activity, true, statusCallback);

        }

    } catch (Exception e) {
        postCallback.onError(e);
    }    
}

private static boolean isSubsetOf(Collection<String> subset, Collection<String> superset) {
    for (String string : subset) {
        if (!superset.contains(string)) {
            return false;
        }
    }
    return true;
}

private static Session initFacebookSession(Context context) {

    Session session = Session.getActiveSession();

    if (session != null) 
        return session;

    /*
    if (savedInstanceState != null)
        session = Session.restoreSession(this, null, sessionStatusCallback, savedInstanceState);
    */

    if (session == null)
        session = new Session(context);

    return session;
}
}

如果我调试到android SDK我可以看到异常是由Session类中的reauthorize方法引发的,因为pendingRequest不是null但我不明白为什么,设置它或我如何检查它,删除它或者我应该做什么？

private void reauthorize(ReauthorizeRequest reauthorizeRequest, AuthorizationType authType) {
    validatePermissions(reauthorizeRequest, authType);
    validateLoginBehavior(reauthorizeRequest);
    if (reauthorizeRequest != null) {
        synchronized (this.lock) {
            if (pendingRequest != null) {   //Here's where the pendingRequest is already set and causes the exception...
                throw new UnsupportedOperationException(
                        "Session: an attempt was made to reauthorize a session that has a pending request.");
            }
            switch (this.state) {
                case OPENED:
                case OPENED_TOKEN_UPDATED:
                    pendingRequest = reauthorizeRequest;
                    break;
                default:
                    throw new UnsupportedOperationException(
                            "Session: an attempt was made to reauthorize a session that is not currently open.");
            }
        }

        authorize(reauthorizeRequest);
    }
}

我搜索了异常没有任何结果,非常感谢任何帮助.

另外,我可以重构整个FacebookUtil.postToFaceBook方法但是在测试时我将它保存在一个方法中以便于阅读.

Answer 1

在要求更多权限时,您需要在当前Session上调用onActivityResult()方法:

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    Logger.d(LOGTAG, "onActivityResult");
    if (RESULT_CANCELED == resultCode) {
        mAuthorizationCanceled = true;
    }
    **mFacebookSession.onActivityResult(this, requestCode, resultCode, data);**
}

这样再次调用StatusCallback并删除pendingRequest.

Answer 2

检查以确保在Activity中添加了这行代码.

public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data); 
    UiLifecycleHelper.onActivityResult();
}
