下面是一些尝试使用带有空格的轨道(“you will”)连接到 Twitter 的代码。它或多或少地以tweetstream4j的方式使用Apache HttpClient和路标 oauth。我用
- 路标核心1.2.1.1.jar
- 路标-commonshttp4-1.2.1.1.jar
- httpclient-4.0.1.jar
- httpcore-4.0.1.jar
如果我运行代码,我会从 Twitter 收到“401 未授权”。如果使用没有空格的轨道(例如,“will”而不是“you will”),它会连接并正常工作(只要我用有效值填写 oauth 消费者密钥和秘密、令牌和令牌秘密)。
有没有人发现问题?我认为这与 POST 正文中轨道参数的 URL 编码有关,但我不确定。我一直在研究路标是如何工作的,直到我的眼睛流血为止。
(这与Java 中带有空格的 Twitter 流 API 相关?)。
