generateAuthResponseback to summary
public String generateAuthResponse(final HttpHost host, final HttpRequest request, final HttpContext context) throws AuthenticationException

Implements org.apache.hc.client5.http.auth.AuthScheme.generateAuthResponse.

Doc from org.apache.hc.client5.http.auth.AuthScheme.generateAuthResponse.

Generates an authorization response based on the current state. Some authentication schemes may need to load user credentials required to generate an authorization response from a CredentialsProvider prior to this method call.

Parameters
request:HttpRequest

The request being authenticated

context:HttpContext

HTTP context

Returns:String

authorization header

Annotations
@Override
Exceptions
AuthenticationException:
if authorization string cannot be generated due to an authentication failure

Doc from org.apache.hc.client5.http.auth.AuthScheme.getName.

Returns textual designation of the given authentication scheme.

Returns:String

getPrincipalback to summary
public Principal getPrincipal()

Implements org.apache.hc.client5.http.auth.AuthScheme.getPrincipal.

Doc from org.apache.hc.client5.http.auth.AuthScheme.getPrincipal.

Returns Principal whose credentials are used to generate an authentication response. Connection based schemes are required to return a user Principal if authorization applies to for the entire life span of connection.

Returns:Principal

user principal

Annotations

getRealmback to summary
public String getRealm()

Implements org.apache.hc.client5.http.auth.AuthScheme.getRealm.

Doc from org.apache.hc.client5.http.auth.AuthScheme.getRealm.

Returns authentication realm. If the concept of an authentication realm is not applicable to the given authentication scheme, returns null.

Returns:String

the authentication realm

Annotations
@Override
isChallengeCompleteback to summary
public boolean isChallengeComplete()

Implements org.apache.hc.client5.http.auth.AuthScheme.isChallengeComplete.

Doc from org.apache.hc.client5.http.auth.AuthScheme.isChallengeComplete.

Authentication process may involve a series of challenge-response exchanges. This method tests if the authorization process has been fully completed (either successfully or unsuccessfully), that is, all the required authorization challenges have been processed in their entirety.

Returns:boolean

true if the authentication process has been completed, false otherwise.

isConnectionBasedback to summary
public boolean isConnectionBased()

Implements org.apache.hc.client5.http.auth.AuthScheme.isConnectionBased.

Doc from org.apache.hc.client5.http.auth.AuthScheme.isConnectionBased.

Determines if the authentication scheme is expected to provide an authorization response on a per connection basis instead of the standard per request basis

Returns:boolean

true if the scheme is connection based, false if the scheme is request based.

Annotations
@Override
isResponseReadyback to summary
public boolean isResponseReady(final HttpHost host, final CredentialsProvider credentialsProvider, final HttpContext context) throws AuthenticationException

Implements org.apache.hc.client5.http.auth.AuthScheme.isResponseReady.

Doc from org.apache.hc.client5.http.auth.AuthScheme.isResponseReady.

Determines whether or not an authorization response can be generated based on the actual authentication state. Generally the outcome of this method will depend upon availability of user credentials necessary to produce an authorization response.

Parameters
credentialsProvider:CredentialsProvider

The credentials to be used for authentication

context:HttpContext

HTTP context

Returns:boolean

true if an authorization response can be generated and the authentication handshake can proceed, false otherwise.

Annotations
@Override
Exceptions
AuthenticationException:
if authorization string cannot be generated due to an authentication failure
processChallengeback to summary
public void processChallenge(final AuthChallenge authChallenge, final HttpContext context) throws MalformedChallengeException

Implements org.apache.hc.client5.http.auth.AuthScheme.processChallenge.

Doc from org.apache.hc.client5.http.auth.AuthScheme.processChallenge.

Processes the given auth challenge. Some authentication schemes may involve multiple challenge-response exchanges. Such schemes must be able to maintain internal state when dealing with sequential challenges

Parameters
authChallenge:AuthChallenge

the auth challenge

context:HttpContext

HTTP context

Annotations
@Override
Exceptions
MalformedChallengeException:
in case the auth challenge is incomplete, malformed or otherwise invalid.
