所有已实现的接口:

AuthScheme, ContextAwareAuthScheme

@NotThreadSafe
public class DigestScheme
extends RFC2617Scheme

Digest authentication scheme as defined in RFC 2617. Both MD5 (default) and MD5-sess are supported. Currently only qop=auth or no qop is supported. qop=auth-int is unsupported. If auth and auth-int are provided, auth is used.

Since the digest username is included as clear text in the generated Authentication header, the charset of the username must be compatible with the HTTP element charset used by the connection.

从以下版本开始:

从以下版本开始:

4.3

DigestScheme

@Deprecated
public DigestScheme(ChallengeState challengeState)

已过时。 (4.3) do not use.

Creates an instance of DigestScheme with the given challenge state.

从以下版本开始:

4.2

DigestScheme

public DigestScheme()

方法详细资料

processChallenge

public void processChallenge(Header header)
                      throws MalformedChallengeException

Processes the Digest challenge.

指定者:

processChallenge 在接口中 AuthScheme

覆盖:

processChallenge 在类中 AuthSchemeBase

参数:

header - the challenge header

抛出:

MalformedChallengeException - is thrown if the authentication challenge is malformed

isComplete

public boolean isComplete()

Tests if the Digest authentication process has been completed.

返回:

true if Digest authorization has been processed, false otherwise.

getSchemeName

public java.lang.String getSchemeName()

Returns textual designation of the digest authentication scheme.

返回:

digest

isConnectionBased

public boolean isConnectionBased()

Returns false. Digest authentication scheme is request based.

返回:

false.

overrideParamter

public void overrideParamter(java.lang.String name,
                    java.lang.String value)

authenticate

@Deprecated
public Header authenticate(Credentials credentials,
                             HttpRequest request)
                    throws AuthenticationException

已过时。 (4.2) Use ContextAwareAuthScheme.authenticate( Credentials, HttpRequest, depends.org.apache.http.protocol.HttpContext)

从接口复制的说明: AuthScheme

Produces an authorization string for the given set of Credentials.

参数:

credentials - The set of credentials to be used for athentication

request - The request being authenticated

返回:

the authorization string

抛出:

AuthenticationException - if authorization string cannot be generated due to an authentication failure

authenticate

public Header authenticate(Credentials credentials,
                  HttpRequest request,
                  HttpContext context)
                    throws AuthenticationException

Produces a digest authorization string for the given set of Credentials, method name and URI.

指定者:

authenticate 在接口中 ContextAwareAuthScheme

覆盖:

authenticate 在类中 AuthSchemeBase

参数:

credentials - A set of credentials to be used for athentication

request - The request being authenticated

context - HTTP context

返回:

a digest authorization string

抛出:

InvalidCredentialsException - if authentication credentials are not valid or not applicable for this authentication scheme

AuthenticationException - if authorization string cannot be generated due to an authentication failure

createCnonce

public static java.lang.String createCnonce()

Creates a random cnonce value based on the current time.

返回:

The cnonce value as String.

toString

public java.lang.String toString()

覆盖:

toString 在类中 AuthSchemeBase
