描述

The change in this PR https://github.com/apache/incubator-openwhisk/pull/4494/files disabled automatic HEAD responses from the controller. So we need an explicit handler to restore this behavior. This has affected at least one downstream project (https://github.com/apache/incubator-openwhisk-devtools/pull/270).

研究方向
Examine the changes in PR #4494 that disabled automatic HEAD responses. Look at the controller's routing code to add an explicit handler for HEAD requests. Ensure it matches the behavior before the PR. Test with the downstream project's PR #270.
