我想我无法在申请注册表中提供主持人。我确实提供了本地主机，但它没有工作。请帮助??

Answer 1

java.net.UnknownHostException: api.linkedin.com表示您无法访问服务器。

检查您是否不在代理服务器后面。如果是这样，您必须找到一种在linkedin API中绕过此代理的方法。

Answer 2

Caused by: java.net.UnknownHostException: api.linkedin.com

您似乎无法访问api.linkedin.com。如果您不在代理服务器后面，请确保您可以访问https://api.linkedin.com。
