parseQueryString

public static java.util.Map parseQueryString(java.lang.String aQS)

Parse a query string, creating a map of name=value pairs
26-Nov-02 olsok -- substituting algorithm from Tomcat 4.0.4 to more correctly deal with %hh escapes and character set encodings. This MAY cause problems for query/post data forwarded via the service interfaces that contains characters previously decoded and resulting in a string that contains something other than 8-bit characters. If this problem arises, olsok thinks the best solution would be to clone the parseURLParameter routine and let it parse characters instead of bytes -- but the issue of whether or not to treat %hh streams is problematic due to possible multiple interpretation.

Parameters:

aQS - The query string to parse, assumed to consist of 8-bit characters in UTF-8 encoding.

Returns:

Map A HashMap of name=value pairs.

parseURLParameters

public static void parseURLParameters(java.util.Map map,
                                      java.lang.String data,
                                      java.lang.String encoding)

Append request parameters from the specified String to the specified Map. It is presumed that the specified Map is not accessed from any other thread, so no synchronization is performed.

IMPLEMENTATION NOTE: URL decoding is performed individually on the parsed name and value elements, rather than on the entire query string ahead of time, to properly deal with the case where the name or value includes an encoded "=" or "&" character that would otherwise be interpreted as a delimiter. NOTE: The input String is assumed to contain 8-bit data only (such as might be retrieved from a servlet query parameter that was encoded in UTF-8 by the browser and handled as ISO-8859-1 by the servlet -- that is, what one typically sees in Tomcat on W2K).

Parameters:

map - Map that accumulates the resulting parameters

data - Input String containing request parameters

encoding - Encoding to use for converting bytes to String

parseURLParameters

public static void parseURLParameters(java.util.Map map,
                                      byte[] data,
                                      java.lang.String encoding)

parse the full byte array as a URL-encoded string

Parameters:

map - output parameter map

data - byte array to parse

encoding - character encoding

parseURLParameters

public static void parseURLParameters(java.util.Map map,
                                      byte[] data,
                                      int useLen,
                                      java.lang.String encoding)

26-Nov-02 OLSOK -- adapted parseParameters from Tomcat 4.0.4 and merged with PegaRULES heuristics (dealing with '&' entities in query strings) in order to get internationalization logic correct and plausible... see also:
Internationalized Resource Identifiers: http://www.w3.org/International/O-URL-and-ident
RFC-2718, Guidelines for new URL Schemes http://www.ietf.org/rfc/rfc2718.txt
HTML 4.0 Recommendation for handling non-ascii characters in URLs (encode the URL as UTF-8, then escape bytes using the %hh mechanism -- this results in using %hh as a byte of a UTF-8 character, NOT a character in some other encoding). http://www.w3.org/TR/REC-html40/appendix/notes.html#h-B.2.1 Append request parameters from the specified String to the specified Map. It is presumed that the specified Map is not accessed from any other thread, so no synchronization is performed.

IMPLEMENTATION NOTE: URL decoding is performed individually on the parsed name and value elements, rather than on the entire query string ahead of time, to properly deal with the case where the name or value includes an encoded "=" or "&" character that would otherwise be interpreted as a delimiter. NOTE: byte array data is modified by this method. Caller beware.

Parameters:

map - Map that accumulates the resulting parameters

data - Input byte array containing request parameters

useLen - length of "data" byte array to consider during parse

encoding - Encoding to use for converting bytes to String

                                                  java.lang.String encoding)

Translate byte array using the specified character encoding

Parameters:

aData - byte array to translate

Returns:

string which is not quoted.
