java - Twitter + Scribe + 无法从空对象获取字符串

Question

我正在尝试使用 scribe 进行 Twitter 授权。当我尝试时

requestToken = service.getRequestToken()

我收到以下错误

14:10:11,305 ERROR [ajp-bio-8009-exec-4][IncludeTag:154]   java.lang.IllegalArgumentException: Cannot get String from a null object

我尝试了以下帖子中提到的答案，但没有任何效果

<强> scribe + twitter > Cannot get String from a null object

每当我尝试包含 TwitterApi.SSL.class 或 TwitterApi.Authenticate.class 时，都会出现“无法解析为类型”错误。

有人遇到过这个问题吗？

Answer 1

使用 .provider(TwitterApi.SSL.class) 代替 .provider(TwitterApi.class)。它应该可以工作。
