java - 如何使用 Eclipse Lyo 获取 IBM RTC 中的工作项？

Question

所以我想使用 LYo 2.1 请求 RTC 3.X 工作项目，但我无法从流中提取它们: 其中客户端是 OslcOAuthClient。

ClientResponse response = client.getResource(resultsUrl, CT_RDF); ChangeRequest req = response.getEntity(ChangeRequest.class);

我想知道什么是正确的资源对象，是 ChangeRequest 还是另一个？我的流中有(当我使用 String.class 时):

Answer 1

RTC3是第一个支持OSLC2的RTC版本，因此它同时支持OSLC1和OSLC2。默认情况下，RTC3 返回 OSLC1 中指定的结果。因此，您的问题可能是 OSLC4J 期望 OSLC2 结果，但得到 OSLC1 结果。

发送请求时，您应该将 OSLC-Core-Version header 设置为 2.0。这应该会导致 RTC3 响应与 OSLC2 规范兼容的结果。
