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 

/**
 * @file
 * A single location to store configuration.
 */

define('CONSUMER_KEY', 'ALPHA_NUMERIC_CONSUMER_KEY');
define('CONSUMER_SECRET', 'ALPHA_NUMERIC_SECRET');
define('OAUTH_CALLBACK', "http://infosys.concordia.ca/MyApps/oauthProxy/callback.php");
define('OAUTH_COOKIE', 'my_twitter_app_oauth');
define('OAUTH_COOKIE_DOMAIN', '.concordia.ca'); //Example ".esri.com"
echo OAUTH_CALLBACK;

//REQUIRED - Encrypt your cookies
//http://si0.twimg.com/images/dev/oauth_diagram.png
//Create your own unique ENCRYPTION_KEY via Encrypt.get_RandomKey()
define('ENCRYPTION_KEY','MY_UNIQUE_ENCRYPTION_KEY'); 
//Create your own unique initialization vector via Encrypt.get_IV()
define('IV','MY_UNIQUE_IV');
define('DEFAULT_TIME_ZONE','America/Toronto');

没有任何代码，很难看出你做错了什么。

您必须在获取初始请求令牌时传递一个完全限定的 URL oauth_callback，或者将回调 URL 硬编码到您的 Twitter 应用程序设置中。

如果您传入 oauth_callback 我相信您必须在设置中输入一个虚拟值，否则它将不起作用。

我的错！应用程序设置中的回调 URL 与 config.php 中的回调 URL 不同。现在一切正常。
