• Constructor Detail

  • HttpAuthHeader

    public HttpAuthHeader(String header)

    Creates a new HTTP-authentication header object from the input header string. The header string is assumed to contain parameters of at most one authentication-scheme (ensured by the caller).

• Method Detail

  • isProxy

    public boolean isProxy()

    Returns:

    True iff this is a proxy authentication header.

  • setProxy

    public void setProxy()

    Marks this header as a proxy authentication header.

  • getUsername

    public String getUsername()

    Returns:

    The username string.

  • setUsername

    public void setUsername(String username)

    Sets the username string.

  • getPassword

    public String getPassword()

    Returns:

    The password string.

  • setPassword

    public void setPassword(String password)

    Sets the password string.

  • isBasic

    public boolean isBasic()

    Returns:

    True iff this is the BASIC-authentication request.

  • isDigest

    public boolean isDigest()

    Returns:

    True iff this is the DIGEST-authentication request.

  • getScheme

    public int getScheme()

    Returns:

    The authentication scheme requested. We currently support two schemes: HttpAuthHeader.BASIC - basic, and HttpAuthHeader.DIGEST - digest (algorithm=MD5, QOP="auth").

  • getStale

    public boolean getStale()

    Returns:

    True if indicating that the previous request from the client was rejected because the nonce value was stale.

  • getRealm

    public String getRealm()

    Returns:

    The realm value or null if there is none.

  • getNonce

    public String getNonce()

    Returns:

    The nonce value or null if there is none.

  • getOpaque

    public String getOpaque()

    Returns:

    The opaque value or null if there is none.

  • getQop

    public String getQop()

    Returns:

    The QOP ("quality-of_protection") value or null if there is none. The QOP value is always lower-case.

  • getAlgorithm

    public String getAlgorithm()

    Returns:

    The name of the algorithm used or null if there is none. By default, MD5 is used.

  • isSupportedScheme

    public boolean isSupportedScheme()

    Returns:

    True iff the authentication scheme requested by the server is supported; currently supported schemes: BASIC, DIGEST (only algorithm="md5", no qop or qop="auth).
