getDirectiveValue

public static java.lang.String getDirectiveValue(java.util.HashMap<java.lang.String,java.lang.String> directivesMap,
                                 java.lang.String directive,
                                 boolean mandatory)
                                          throws javax.security.sasl.AuthenticationException

A directive is a parameter of the digest authentication process. Returns the value of a directive from the map. If mandatory is true and the value is null, then it throws an AuthenticationException.

参数:

directivesMap - the directive's map

directive - the name of the directive we want to retrieve

mandatory - is the directive mandatory

返回:

the mandatory value as a String

抛出:

javax.security.sasl.AuthenticationException - if mandatory is true and if directivesMap.get(directive) == null

copyDirective

public static void copyDirective(java.util.HashMap<java.lang.String,java.lang.String> directives,
                 java.lang.StringBuilder sb,
                 java.lang.String directive)

Copy the directive to the StringBuilder if not null. (A directive is a parameter of the digest authentication process.)

参数:

directives - the directives map

sb - the output buffer

directive - the directive name to look for

copyDirective

public static java.lang.String copyDirective(java.util.HashMap<java.lang.String,java.lang.String> src,
                             java.util.HashMap<java.lang.String,java.lang.String> dst,
                             java.lang.String directive)

Copy the directive from the source map to the destination map, if it's value isn't null. (A directive is a parameter of the digest authentication process.)

参数:

src - the source map

dst - the destination map

directive - the directive name

返回:

the value of the copied directive

parseDirectives

public static java.util.HashMap<java.lang.String,java.lang.String> parseDirectives(byte[] buf)
                                                                            throws javax.security.sasl.SaslException

Parses digest-challenge string, extracting each token and value(s). Each token is a directive.

参数:

buf - A non-null digest-challenge string.

返回:

A Map containing the aprsed directives

抛出:

javax.security.sasl.SaslException - if the String cannot be parsed according to RFC 2831

isLws

public static boolean isLws(byte b)

Is character a linear white space ? LWS = [CRLF] 1*( SP | HT ) Note that we're checking individual bytes instead of CRLF

参数:

b - the byte to check

返回:

true if it's a linear white space

stringTo8859_1

public static java.lang.String stringTo8859_1(java.lang.String str)
                                       throws java.io.UnsupportedEncodingException

Used to convert username-value, passwd or realm to 8859_1 encoding if all chars in string are within the 8859_1 (Latin 1) encoding range.

参数:

str - a non-null String

返回:

a non-null String containing the 8859_1 encoded string

抛出:

java.io.UnsupportedEncodingException - if we weren't able to decode using the ISO 8859_1 encoding

getSingleValuedHeader

public static java.lang.String getSingleValuedHeader(java.util.Map<java.lang.String,java.util.List<java.lang.String>> headers,
                                     java.lang.String key)

Returns the value of the named header. If it has multiple values then an IllegalArgumentException is thrown

参数:

headers - the http headers map

key - the key of the header

返回:

the value of the http header

addValueToHeader

public static void addValueToHeader(java.util.Map<java.lang.String,java.util.List<java.lang.String>> headers,
                    java.lang.String key,
                    java.lang.String value,
                    boolean singleValued)

Adds an header to the provided map of headers.

参数:

headers - the http headers map

key - the name of the new header to add

value - the value of the added header

singleValued - if true and the map already contains one value then it is replaced by the new value. Otherwise it simply adds a new value to this multi-valued header.
