How to resolve 401 Unauthorized The request requires user authentication. The response MUST include a WWW-Authenticate header field (section 14.47) containing a challenge applicable to the requested resource in Java

In this blog, we are going to know about resolving the 401 Unauthorized The request requires user authentication. The response MUST include a WWW-Authenticate header field (section 14.47) containing a challenge applicable to the requested resource.

Recently I was testing an API and I got this error “401 Unauthorized The request requires user authentication. The response MUST include a WWW-Authenticate header field (section 14.47) containing a challenge applicable to the requested resource”.

In Java we can exclude or disable the authorization in our application by searching the authorization related code i.e.,

//.filter(oAuth);

If the OAuth Discovery spec weren’t already out of date and a replacement spec hadn’t been created, it would specify what to put in the WWW-Authenticate header.

According to RFC2617, the auth-scheme can be anything; hence, if you absolutely want a 401, creating something new like WWW-Authenticate is not strictly against the specification. OpenID location=”http://my/login/location” realm=“My Realm” Having said that, it is unknown how other people’s codes will act when you do that.
