Question

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轴数据。

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“重定向回应用程序”消息，但在重定向到http://MyDomainName.com/callback.php?oauth_token=someToken&oauth_verifier=someOtherToken后，页面未显示在浏览器和重定向不会发生。手动返回应用程序页面，用户未登录，必须再次登录。有人可以帮我这个吗？

CONFIG.PHP

/**
 * @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');

Answer 1

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将完全限定的网址传递为oauth_callback，或者将回调网址硬编码到您的Twitter应用settings中。

如果您传入oauth_callback，我相信您必须在设置中输入虚拟值，否则它将无效。

Answer 2

我的坏！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。

Twitter API v1.1重定向到应用程序不起作用
