我正在使用CQ5.6并从服务进行servlet调用。在我的错误日志中，我从日志语句中得到“java.io.IOException：Server返回HTTP响应代码：401 for URL：http://localhost:4502/content/sports/jcr:content/parSports/sportsscores.scores”。
如何解决此问题？ （我没有用凭证做任何事情）
这是我的服务：

I don't think what you are trying to do make much sense. Why are you doing an Http connection to the instance itself? You are trying to access an authoring instance, which requires permissions to access it.
It seems you are doing things backwards. You should have a service where you access that third party service, and then use it in your servlet. That way you don't need to use an http connection to the same instance.
Having said that, if you still want to process a request through CQ5 from itself, you can use the SlingRequestProcessor上触发，无需打开实际连接即可在内部处理请求
