下面是一些嘗試使用帶有空格的軌道(「您將會」)連接到Twitter的代碼。它或多或少以tweetstream4j的方式使用Apache HttpClient和signpost oauth。我用使用Apache HttpClient和Oauth路標連接到帶有空格軌道的Twitter流媒體API?
- 路標 - 核心1.2.1.1.jar
- 路標,commonshttp4-1.2.1.1.jar
- 的HttpClient-4.0.1.jar
- 的HttpCore-4.0.1.jar
如果我運行代碼,我會從Twitter獲得「401未經授權」。如果使用不帶空格的軌跡(例如,「will」而不是「you will」),它會連接並正常工作(只要我填寫oauth消費者密鑰和祕密,令牌和具有有效值的令牌祕密)。
有沒有人發現問題?我認爲它與POST正文中的tracks參數的URL編碼有關,但我不確定。我一直在挖掘路標如何工作,直到我的眼睛流血。
(這與Twitter streaming API in Java with tracks that have spaces?有關)。
