getAnonymousResolver：配置不允许匿名访问 - 请求凭据

Question

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 returned HTTP response code: 401 for URL: http://localhost:4502/content/sports/jcr:content/parSports/sportsscores.scores"。

如何解决这个问题？（我没有使用凭据做任何事情）

这是我的服务：

我认为您尝试做的事情没有多大意义。你为什么要对实例本身进行 Http 连接？您正在尝试访问创作实例，这需要访问权限。

看来你是在倒退。您应该有一个服务，您可以在其中访问该第三方服务，然后在您的 servlet 中使用它。这样您就不需要对同一实例使用 http 连接。

话虽如此，如果您仍想通过 CQ5 本身处理请求，则可以使用 SlingRequestProcessor 在内部处理请求，而无需打开实际连接
