无法使用java通过REST从VSTS获取数据...总是出现连接超时错误

Question

我正在尝试通过JAVA中的REST连接VSTS，但总是让连接超时。使用此代码，我可以使用http连接，但在尝试连接https时始终会出错。将在评论中发布错误。得到此错误 - > com.sun.jersey.api.client.ClientHandlerException：java.net.SocketTimeoutException：connect timed out

根据您的描述，它似乎与您的代码无关。

我建议您检查TFS服务器是否有Https绑定。

如果没有Https绑定，请尝试添加相应的Https绑定
