@0xff-dev @bjwswang @zqq454224016 any ideas about test? we can add it in next pr.

IMO, we can update basic-auth in example-test, just add cert with username and password. How we build certificates and the format of certificates can be used as a reference for front-end page display and tester testing.

LGTM. We can do it in next pr. @zqq454224016
