android - 在 Facebook Android SDK 3.0 中将读取会话切换为发布会话

Question

我真的需要关闭一个会话（比如从一个 READ 会话），并建立一个新的 PUBLISH 活动会话，以便我执行 publish_stream 请求。

如果是（或不是），我有什么有效的方法吗？

Answer 1

不需要。打电话session.requestNewPublishPermissions(new Session.NewPermissionsRequest(this, PERMISSIONS));

其中PERMISSIONS是（相应地改变它）：

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

完成后，您将收到回调：

SessionState.OPENED_TOKEN_UPDATED

检查上述状态并通过调用再次发布您的消息：

Request statusRequest=Request.newStatusUpdateRequest(Session.getActiveSession(), mStatus.getText().toString(), reqestCallback);
if(statusRequest!=null){
statusRequest.executeAsync();

    private class App_Session_StatusCallback implements Session.StatusCallback
    {
        @Override
        public void call(Session session, SessionState state, Exception exception) 
        {
            Log.d("asd", "state changed");
            handleSessionStateChanged(session, state, exception);
        }
    }

    private void handleSessionStateChanged(Session session, SessionState state, Exception exception)
    {
        if(state == SessionState.OPENED_TOKEN_UPDATED)
        {
            Request statusRequest=Request.newStatusUpdateRequest(Session.getActiveSession(), mStatus.getText().toString(), reqestCallback);
            if(statusRequest!=null){
                statusRequest.executeAsync();
            }
        }

        if(session != null)
        {
            if(session.isOpened())
            {
                Log.d("asd", "session is opened");

                Log.d("asd", "Token = " + session.getAccessToken());
                Log.d("asd", "Expiry = " + session.getExpirationDate().toGMTString());
            }
            else
            {
                Log.d("asd", "session is NOT opened");
            }
        }
    }

    Session.getActiveSession().requestNewPublishPermissions(new Session.NewPermissionsRequest(this, Arrays.asList("publish_actions")));
