我想我不能在申请注册表中提供主机。我确实提供了本地主机，但它不工作。请帮帮忙？？

Answer 1

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

看起来您没有访问api.linkedin.com的网络权限。请确保，无论您是否在代理服务器之后，您都可以访问https://api.linkedin.com。

Answer 2

java.net.UnknownHostException: api.linkedin.com表示您无法连接到服务器。

检查您的服务器是否位于代理服务器之后。如果是这样，您必须找到在linkedin API中绕过此代理的方法。
