我是 Twitter API 的新手，我正在尝试在我的应用程序中获取用户时间线数据。
我已正确设置应用程序设置和 config.php 文件，因此用户成功登录并看到“重定向回您的应用程序”消息，但在重定向到http://MyDomainName.com/callback.php?oauth_token=someToken&oauth_verifier =someOtherToken页面不会显示在浏览器中并且不会发生重定向。手动返回应用程序页面，用户未登录，必须再次登录。谁能帮我解决这个问题？
配置文件
/**

* A single location to store configuration.

define('CONSUMER_SECRET', 'ALPHA_NUMERIC_SECRET');
define('OAUTH_CALLBACK', "http://infosys.concordia.ca/MyApps/oauthProxy/callback.php");
define('OAUTH_COOKIE', 'my_twitter_app_oauth');
